DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0031] Hereinbelow, a description is given of the structure of
a digital camera according to an embodiment of the present invention
with reference to FIG. 1. According to the present invention, a
digital camera (hereinafter, simply referred to as a camera) 10
comprises: an optical lens (not shown); a charge coupled-device
(hereinafter, referred to as a CCD) 11; an analog signal processing
unit 12; an analog/digital converter (hereinafter, referred to as
an A/D converter) 13; a digital signal processing unit 14; a memory
15; a microcomputer 16; a recording medium 17; a liquid crystal
display panel (hereinafter, referred to as an LCD) 18; an input
button unit 19; a touch panel 20; and a microphone 21.
[0032] The CCD 11 forms an image of a subject through the optical
lens, photoelectrically converts the subject image, and generates
an analog electric signal.
[0033] The analog signal processing unit 12 amplifies and filters
the waves of the analog electric signal generated by the CCD 11.
[0034] The A/D converter 13 converts the analog electric signal
from the analog signal processing unit 12 into a digital signal.
[0035] The digital signal processing unit 14 performs predetermined
digital signal processing of the digital signal from the A/D converter
13, and generates video data. In the digital signal processing,
the still-image photographing operation uses JPEG system, and the
moving-image photographing operation uses MPEG2 system for coding,
thereby generating the compressed digital video data.
[0036] The memory 15 temporarily records the digital video data
generated by the digital signal processing unit 14.
[0037] The microcomputer 16 controls the driving operation of the
digital signal processing unit 14, and controls the photographing
operation of the digital camera 10.
[0038] The recording medium 17 records the digital video data which
is temporarily recorded in the memory 15 under the control of the
microcomputer 16. The recording medium 17 is a recording medium
such as a semiconductor memory, which is detachably attached to
the camera 10 and to/from which the digital video data is written
or is read.
[0039] The LCD 18 displays a photographing image based on the digital
video data that is generated by the digital signal processing unit
14 and is temporarily recorded to the memory 15 and the digital
video data recorded to the recording medium 17. Further, the LCD
18 displays a screen for selecting a photographing function of the
camera 10, in addition to the photographing image of the digital
video data recorded to the recording medium 17 and the memory 15.
[0040] The input button unit 19 includes an instructing button
for measuring the distance to the subject and the brightness of
the subject, a shutter button, a zoom button, a selecting button
of various photographing modes, and a power button. Information
on the button operated by the input button unit 19 is inputted to
the microcomputer 16.
[0041] The touch panel 20 is arranged to an image display screen
of the LCD 18. A user touches, via the touch panel 20, a screen
for selecting the photographing function displayed on the LCD 18
and then the coordinate of the user touching position is detected.
The microcomputer 16 determines the coordinate of the finger touching
position detected by the touch panel 20 and the position of the
selecting screen of the photographing function displayed on the
LCD 18, and recognizes the photographing function selected by the
user.
[0042] The microphone 21 inputs voice as a part of user identification
information of the camera 10, which will be described later.
[0043] The microcomputer 16 comprises a ROM 16a which stores a
program of various control modes for controlling the driving of
the digital signal processing unit 14 and a program of user confirming
processing and registering processing of the photographing function
used by every user and registering processing of the user including
the owner, which will be described later. Further, the microcomputer
16 comprises a RAM 16b which is used as a working area of the program
read from the ROM 16a. In the microcomputer 16, the program is developed
in accordance with the input operation using the input button unit
19 and the touch panel 20, and the driving of the digital signal
processing unit 14 and the photographing function are controlled.
[0044] In the camera 10, the power button arranged to the input
button unit 19 is turned on, the shutter button is operated, the
CCD 11 as an image pick-up unit is driven, and the subject image
is converted into the analog electric signal. The analog electric
signal is amplified and is subjected to analog signal processing
such as filtering processing by the analog signal processing unit
12 as a signal processing unit. Then, the A/D converter 13 converts
the analog electric signal into the digital signal. Under the control
of the microcomputer 16, the digital signal processing unit 14 encodes
the digital signal of the still image in JPEG system and the digital
signal of the moving image in MPEG2 system. Further, the digital
signal is subjected to the digital signal processing such as compression
and is converted into the digital video data. The digital video
data is temporarily recorded to the memory 15 as a storing unit,
and is read from the memory 15 based on the control of the microcomputer
16 and is recorded to the recording medium 17. Furthermore, the
digital video data read from the memory 15 is decoded and decompressed,
and is sent to the LCD 18 as a display unit, serving as a video
signal. That is, the LCD 18 displays the still image or moving image
which is picked-up and is subjected to the signal processing by
the CCD 11, the analog signal processing unit 12, the A/D converter
13, and the digital signal processing unit 14. The still image or
moving image is recorded to the recording medium 17, serving as
the digital video data.
[0045] The camera 10 sets the registration of the owner of the
camera 10 and the user except for the owner, further sets the registration
of the photographing function which can be used by each of the user,
and confirms the user when the user uses the camera 10.
[0046] The microcomputer 16 of the camera 10 stores a control program
having a mode for setting the registration of the owner and the
user except for the owner, a mode for setting the photographing
function which can be used by each of the user, and a user registering
mode. Further, the microcomputer 16 stores a control program of
a user confirming mode for confirming whether or not the user has
already been registered for user, upon using the camera 10 for photographing
operation.
[0047] A description is given of the operation in the user registering
mode of the control program stored in the microcomputer 16 with
reference to FIGS. 2 to 5. First, a description is given of the
conceptual definition of the owner of the camera 10 and the user
other than the owner. For example, it is assumed that when the family
uses the camera 10, a husband as a purchaser of the camera 10 is
the owner of the camera 10, and a wife and a child of the owner
serving as the family of the owner use the camera 10. Further, it
is assumed that the owner of the camera 10 freely uses all the photographing
functions provided for the camera 10, and limits the user registration,
user addition, user deletion, and photographing function used by
each user. Furthermore, it is assumed that the user is permitted
in the use of the camera 10 within the range of the photographing
function that is set by the owner.
[0048] A description is given of the registering and setting of
the owner and the user in the user registering mode of the camera
10 with reference to FIG. 2.
[0049] The owner turns on a power button arranged to the input
button unit 19, and the camera 10 enters an initial starting state.
In step S1, the owner operates an operating mode selecting button
of the input button unit 19 in the camera 10 in the initial starting
state and thus the LCD 18 displays an owner setting screen 31.
[0050] In step S1, the microcomputer 16 reads the user registering
mode stored in the ROM 16a based on the operating mode selecting
button of the input button unit 19, and develops the mode to the
RAM 16b. The microcomputer 16 displays the owner setting screen
31 on the LCD 18 via the digital signal processing unit 14 in accordance
with the user registering mode.
[0051] Referring to FIG. 3, the owner setting screen 31 comprises:
an owner name input column 31a of the camera 10; a name input button
31b; a password input column 31c of the owner; a password input
button 31d; a start message 31e of "usually start by this user";
a YES/NO confirming button 31f; a user setting button 31g which
shifts to the setting screen of the user other than the owner; and
an end button 31h which ends the owner setting screen 31.
[0052] In step S2, the owner inputs the owner name in the owner
name input column 31a in accordance with the owner setting screen
31 displayed on the LCD 18. The owner touches the name input button
31b of the owner setting screen 31 displayed on the LCD 18 and thus
the owner name is inputted as shown in step S2. The touch panel
20 detects the touching operation at the position of the name input
button 31b by the owner. The microcomputer 16 enables the touch
panel 20 to display a character input screen (not shown), in place
of the owner setting screen 31, based on positional information
on the owner touching operation and positional information of the
name input button 31b displayed on the LCD 18. The character input
screen displays a character list of alphabet, number, and symbol.
The owner directly touches and selects his name character from the
character list displayed on the LCD 18. Alternatively, a cursor
which is movable in the vertical and horizontal directions on the
character list is displayed, then, the cursor is moved in the vertical
and horizontal directions, and characters of his name are selected.
The microcomputer 16 returns the display screen of the LCD 18 to
the owner setting screen 31 after ending the character input of
the name from the character list displayed on the LCD 18 by the
owner, and the characters of the name inputted to the input column
31a are displayed.
[0053] Next, in step S3, the owner inputs owner's password in the
password input column 31c in accordance with the owner setting screen
31 displayed on the LCD 18. The owner touches the password input
button 31d of the owner setting screen 31 displayed on the LCD 18,
thereby inputting the password in step S3. The touch panel 20 detects
that the owner touches the position of the password input button
31d. The microcomputer 16 enables the LCD 18 to display a password
input screen (not shown), in place of the owner setting screen 31,
based on positional information of the owner touching operation
and positional information of the password input button 31d displayed
on the LCD 18. The password includes a character, figure, voice,
and face video image.
[0054] In the case of setting the registration of the password
with characters, similarly to the input of the owner name described
in step S2, the LCD 18 displays the character list for inputting
the character, and the character selected from the character list
is registered as the password.
[0055] In the case of setting the registration of the password
with the figure, the LCD 18 displays a figure input screen. The
touch panel 20 detects a favorite figure which is drawn by the owner
on the figure input screen displayed on the LCD 18. Figure data
detected by the touch panel 20 is registered as the password.
[0056] In the case of setting the registration of the password
with the voice, the owner himself speaks a specific word to the
microphone 21, a voice signal from the microphone 21 is converted,
voice signal data is generated, and the data is inputted as the
password.
[0057] In the case of setting the registration of the password
with the face video image, the owner photographs his own face by
the camera 10, and video data of the photographed face is inputted
as the password.
[0058] The microcomputer 16 returns the display screen on the LCD
18 to the owner setting screen 31 after ending the setting of registration
of the password, and displays "*****" data indicating
the end of registering setting of the password on the password input
column 31c.
[0059] After ending the setting for inputting the password in step
S3, the owner sets the start message 31e in accordance with the
owner setting screen 31 displayed on the LCD 18. In step S4, the
owner touches the YES/NO confirming button 31f in response to the
start message 31e of "usually start by this user" on the
owner setting screen 31 displayed on the LCD 18, thereby setting
the start message 31e. The owner touches the YES/NO confirming button
31f of the touch panel 20 and then the microcomputer 16 switches
the YES/NO confirming button 31f to "YES" or "NO",
thereby displaying the result. In the case of using the camera 10
only by the owner, or preferentially using the camera 10 by the
owner, the YES/NO confirming button 31f is set to "YES".
The camera 10 sets the YES/NO confirming button 31f to "NO"
in the case of preferentially using the camera 10 by the user other
than the owner.
[0060] After ending the input of the owner name, the setting of
the password, and the setting of the start message 31e in steps
S2 and S3, in step S4, the owner selects and touches, from the owner
setting screen 31, any of the user setting button 31g which sets
a mode for setting the user other than the owner and the end button
31h which ends the owner setting screen 31.
[0061] When the touch panel 20 detects in step S4 that the owner
touches the end button 31h, the microcomputer 16 ends the display
operation of the owner setting screen 31 displayed on the LCD 18.
The owner freely uses all the photographing functions of the camera
10.
[0062] After the touch panel 20 detects in step S4 that the owner
touches the user setting button 31g, the microcomputer 16 executes
a mode for setting of the user other than the owner in steps subsequent
to step S5.
[0063] The owner touches the user setting button 31g and then,
in step S5, a user setting screen 32 is displayed on the LCD 18.
Referring to FIG. 4, the user setting screen 32 comprises: a user
name input column 32a of the user (owner's family according to the
embodiment) other than the owner of the camera 10; a name input
button 32b; a password input column 32c of the user; a password
input button 32d; a start message 32e of "usually start by
this user"; a YES/NO confirming button 32f; a function setting
button 32g for setting the photographing function permitted to the
user; a user setting button 32h which shifts to the setting screen
of another user other than the current user; and an end button 32i
which ends the user setting screen 32.
[0064] In step S6, the owner sets and registers, in accordance
with the user setting screen 32 displayed on the LCD 18, the user
name, e.g., his wife name if the user is his wife or his child name
if the user is his child, in the user name input column 32a. The
input operation of the password in step S6 is the same as that in
step S2.
[0065] In step S7, the owner sets and registers the password of
the user whose name is inputted to the user name input column 32a
to the password input column 32c in accordance with the user setting
screen 32 displayed on the LCD 18. The password input operation
in step S7 is the same as that in step S3.
[0066] The setting and registration of the user password end and
then the owner selects the YES/NO confirming button 32f in response
to "usually start by this user" of the start message 32e
on the user setting screen 32. The selection of the YES/NO confirming
button 32f is the same as that of the YES/NO confirming button 31f
on the owner setting screen 31.
[0067] In the case of using the camera 10 only by the user who
is set for registration, or preferentially using the camera 10 by
the user who is set for registration, the owner sets the YES/NO
confirming button 32f to "YES". In the case of using camera
10 not by the owner or preferentially using camera 10 not by another
user, the owner sets the YES/NO confirming button 32f to "NO".
[0068] In step S8, the owner touches the function setting button
32g which sets the photographing function upon using the camera
10 by the user who is set for registration in steps S6 and S7. After
the touch panel 20 detects in step S8 that the owner touches the
function setting button 32g, in step S9, the microcomputer 16 displays
a function setting screen 33 on the LCD 18, in place of the user
setting screen 32.
[0069] Referring to FIG. 5, the function setting screen 33 comprises:
a permission/prohibition selecting button 33a' of a format setting
function 33a; a permission/prohibition selecting button 33b' of
a video data deleting function 33b; a permission/prohibition button
33c' of another folder viewing function 33c; a permission/prohibition
button 33d' of the folder creating function 33d; a selecting button

[0071] In the beginner photographing mode, upon a photographer
operating the shutter button, first, the automatic setting and photographing
operation is performed, including the focusing adjustment of the
optical lens by the distance measurement to the subject, the exposure
by light measurement of the subject, the adjustment of a shutter
speed, and strobe light-emission control. In the professional photographing
mode, the operations are individually set and an image is photographed
in accordance with the photographer's selection and the subject,
including the focusing adjustment, the setting of exposure and shutter
speed, and the presence or absence of strobe light-emission.
[0072] In step S10, the owner selects and registers the photographing
function which is permitted to the user, in accordance with the
function setting screen 33 displayed on the LCD 18. With regard
to the format setting function 33a, the owner selects the permission
or prohibition by operating the permission/prohibition selecting
button 33a'. With regard to the deleting function 33b of the video
data, the owner selects the permission or prohibition by operating
the permission/prohibition selecting button 33b'. With regard to
the folder viewing function 33c, the owner selects the permission
or prohibition by operating the permission/prohibition button 33c'.
With regard to the folder creating function 33d, the owner selects
the permission or prohibition by operating the permission/prohibition
button 33d'. With regard to the photographing operation mode function
33e, the owner selects the beginner photographing operation or professional
photographing operation by operating the selecting button 33e'.
[0073] Referring to FIG. 5, the function setting screen 33 is an
example in which the child is permitted as the user. The format
setting function 33a is set to the prohibition, the deleting function
33b is set to the permission regarding the video data photographed
by the user himself, the folder viewing function 33c is set to the
prohibition regarding the video data of another user, the folder
creating function 33d is set to the permission regarding the video
data photographed by the user himself, and the photographing operation
mode function 33e is set to the beginner photographing mode.
[0074] The owner ends the function setting in accordance with the
function setting screen 33 in step S10. Then, the owner operates
the end button 33g. By operating the end button 33g, the microcomputer
16 returns to step S4 whereupon the user setting screen 32 is displayed
again on the LCD 18 and it is determined whether or not the setting
of another user continues.
[0075] The photographing function set by the function setting screen
33 is not limited to the format setting function 33a to the photographing
operation mode function 33e, and may be applied to another operating
function, other than the above-mentioned functions. The owner of
the camera 10 freely uses all the photographing functions, and further
freely views the folder of the user other than the owner and freely
deletes the video data. However, the photographing function used
by the owner is limited, at least the deletion and the viewing of
the video data photographed by the user other than the owner may
be prevented.
[0076] As mentioned above, the camera 10 comprises: a user setting
unit for setting the registration of the owner in steps S2 and S3
and of a plurality of users in steps S6 and S7 and for setting the
registration of the password serving as identification information
for identifying the user including the owner; and a using photographing-function
setting unit for setting and registering the photographing function
which permits the user to the user registered in steps S9 and S10.
[0077] Next, a description is given of a mode for confirming the
user in the photographing operation of the camera 10 with reference
to FIGS. 6 to 16.
[0078] In step S21, the user turns on the power button included
in the input button unit 19 in the camera 10, and sets the starting
state for photographing operation. The camera 10 enters the starting
state and then, in step S22, the microcomputer 6 sets the number
N of counting of a counter to zero (N=0).
[0079] In step S23, the microcomputer 16 reads the mode for confirming
the user from the control program stored in the ROM 16a, and displays
a user selecting screen 34 on the LCD 18.
[0080] Referring to FIG. 7, the user selecting screen 34 displays
the list of users including the owner which is registered and is
set to the camera 10.
[0081] The user selecting screen 34 displays, e.g., an owner name
34a, a child name 34b, and a wife name 34c which are registered
by inputting the names of the owner and the user as mentioned above
with reference to FIG. 2. Further, the user selecting screen 34
comprises a selecting button 34d with up and down arrows which vertically
operates a cursor for selecting the user from the user names 34a
to 34c, and a determining button 34e which determines the user selected
by the selecting button 34d.
[0082] Referring to FIG. 7, in step S24, the user of the camera
10 moves the cursor to the user name by using the selecting button
34d, and selects the user by operating the determining button 34e.
For example, referring to FIG. 7, when the user is the child, the
cursor is moved to the child name 34b by using the selecting button
34d, and the determining button 34e is operated.
[0083] When the YES/NO confirming button 31f of the start message
31e is set to "YES" on the owner setting screen 31 as
mentioned above with reference to FIG. 3 or when the YES/NO confirming
button 32f of the start message 32e is selected "YES"
on the user setting screen 32 as mentioned above with reference
to FIG. 4, the user selecting screen 34 is set so that the cursor
is positioned to the user of "YES" of the YES/NO confirming
button 31f or the YES/NO confirming button 32f. That is, in the
selection and setting of the YES/NO confirming button 31f and the
YES/NO confirming button 32f of the start message 31e and the start
message 32e, the start operation of the preferential user of the
camera 10 is fast executed by setting the user who frequently uses
the camera 10 or preferentially uses the camera 10.
[0084] After ending the selection of the user of the camera 10
in step S24, in step S25, the microcomputer 16 displays a password
log-in screen 35 for inputting the user password on the LCD 18.
[0085] In steps S3 and S7 as mentioned above with reference to
FIG. 2, on the password log-in screen 35, the password is inputted
with the character, figure, voice, or face video image which is
used upon setting the password of the owner and the user other than
the owner. Herein, a description is given of an example of the password
comprising the character, and the input and comparison of the password
comprising the figure, voice, or face video image will be described
later.
[0086] In step S25, the password log-in screen 35 is displayed
to input the password comprising the character on the LCD 18. Referring
to FIG. 8, the password log-in screen 35 comprises: a user name
display 35a for displaying the user name; a user character password
input column 35b; a password input button 35c; a return button 35d
which returns the screen from the password log-in screen 35 of the
character to the user selecting screen 34; and a log-in button 35e
for log-in of the input password comprising the character.
[0087] The user operates the password input button 35c of the password
log-in screen 35. Although not shown, the microcomputer 16 displays
the list of characters, in place of the password log-in screen 35,
similarly to steps S3 and S7. The user selects and inputs the characters
of the password which is registered from the list of characters.
When the characters of the password are inputted, the microcomputer
16 returns the display screen of the LCD 18 to the password log-in
screen 35 from the list of characters.
[0088] Next, in step S26, the microcomputer 16 adds one to the
number N of counting of the counter (N=N+1), and the number N of
the password input times is counted.
[0089] Subsequently, in step S27, the microcomputer 16 determines
the password by comparing the user name selected in step S24 and
the user password inputted in step S25 with the user name and the
password registered in advance. When the microcomputer 16 determines
in step S27 that the user name and the password are correct, in
step S28, the microcomputer 16 starts the camera 10 which is operated
for photographing operation based on the photographing function
permitted to the user which is set in advance.
[0090] When the microcomputer 16 determines in step S27 that the
password inputted in step S25 is not correct, in step S29, the microcomputer
16 determines whether or not the number N of input times of the
password counted in step S26 is 3 (N=3). When the microcomputer
16 determines in step S29 that the number N of input times of the
password is 3, in step S30, the microcomputer 16 disconnects the
power switch of the camera 10 so as to prevent the photographing
operation. When the microcomputer 16 determines in step S29 that
the number N of input times of the password is exceeding 3, the
microcomputer 16 displays an error message so that the correct password
is inputted to the LCD 18, and the processing returns to step S25
whereupon the password is inputted.
[0091] In the user confirming mode, regarding the photographing
function of the camera 10 for every user and the user name and password
including the owner of the camera 10 which are registered in advance,
it is determined whether or not the user is the user to whom the
use of the camera 10 is permitted by comparing the user name inputted
upon using the camera 10 with the user password. Further, a user
determining unit is provided to enable the photographing operation
using the photographing function set to the use-permitted user.
[0092] Thus, in the camera 10, the identification of the owner
and the user of the camera 10 is possible. Further, it is possible
to prevent the erroneous deletion and free viewing of the video
data which is photographed by another user.
[0093] In the description of the password input in step S25, the
user password comprises the character. As mentioned above, in the
camera 10, the password can be set by using the figure, voice, and
face video image, in addition to the character. Then, a description
is given of the password input in step S25 upon setting the password
comprising the figure, voice, and face video image, other than the
character. The input method of the password can be applied to the
password input in steps S2 and S7 as mentioned above.
[0094] In step S24, the user of the camera 10 is selected. In step
S25, the microcomputer 16 displays a password log-in screen 36 shown
in FIG. 9 on the LCD 18. The password log-in screen 36 comprises:
a user name display 36a which displays the user name; a user character
password input column 36b; a password input button 36c; a face video
password selecting button 36d; a voice password selecting button
36e; a figure password selecting button 36f; a return button 36g;
and a log-in button 36h.
[0095] In the case of the password comprising the character, the
user touches the user character password input column 36b and the
password input button 36c on the password log-in screen 36, then,
displays the character password input screen on the LCD 18 as mentioned
above, and inputs the character password.
[0096] In the case of the password comprising the face video image,
the user operates the face video password selecting button 36d and
the password input button 36c which are shown by the shade in FIG.
9 and thus displays a face photographing screen 37 on the LCD 18
as shown in FIG. 10. The face photographing screen 37 comprises:
a user name display 37a; a message 37b of "Photograph user
face"; a cancel button 37c; and a registering button 37d.
[0097] Referring to FIG. 11, the user photographs his face by directing
the camera 10 to his face in accordance with the face photographing
screen 37. After photographing the user's face, the user touches
the registering button 37d, thereby capturing video data of the
photographed user's face. Further, the display of the LCD 18 is
returned to the password log-in screen 36.
[0098] When the user erroneously selects and displays the face
photographing screen 37 on the LCD 18, he touches the cancel button
37c and returns the display operation on the LCD 18 to the password
log-in screen 36.
[0099] On the password log-in screen 36, the user operates the
log-in button 36h so as to compare the face video image photographed
on the face photographing screen 37 with the user face video image
which is set in advance. The microcomputer 16 confirms the user
password by touching the log-in button 36h. If the input password
matches the password of the face video image, the microcomputer
16 enables the photographing operation using the photographing function
permitted to the user.
[0100] In the case of the password comprising the voice, the user
touches the voice password selecting button 36e which is shown by
the shade in FIG. 12 and the password input button 36c, and displays
a voice input screen 38 on the LCD 18 as shown in FIG. 13. The voice
input screen 38 comprises: a user name display 38a; a message 38b
of "speak registered word"; a cancel button 38c; and a
registering button 38d.
[0101] Referring to FIG. 14, the user generates, to the microphone
21 of the camera 10, the voice of a word that is set as a voice
password in advance. The generated word is converted into a voice
signal by the microphone 21. After generating the voice of the user
word, the user touches the registering button 38d and then the voice
signal is captured. Then, the display operation on the LCD 18 is
returned to the password log-in screen 36. Further, when the user
erroneously selects and displays the voice input screen 38, he touches
the cancel button 38c and the display operation on the LCD 18 is
returned to the password log-in screen 36.
[0102] On the password log-in screen 36, the user touches the log-in
button 36h so as to compare the voice signal captured on the voice
input screen 38 with the voice signal of the user which is set in
advance. The microcomputer 16 confirms the password of the user
by the user touching the log-in button 36h. If the input password
matches the password comprising the voice, the microcomputer 16
enables the photographing operation using the predetermined function
permitted to the user.
[0103] In the case of the password comprising the figure, the user
touches the figure password selecting button 36f which are shown
by the shade in FIG. 15 and the password input button 36c, and displays
a figure input screen 39 on the LCD 18 as shown in FIG. 16. The
figure input screen 39 comprises: a message 39a of "Draw registered
figure"; a figure drawing area 39b; a cancel button 39c; and
a registering button 39d. Although not shown, the figure input screen
39 may display the user name.
[0104] Referring to FIG. 16, the user draws a FIG. 39b' which is
set as a figure password in advance in the figure drawing area 39b
in accordance with the figure input screen 39 by using the finger
or an elongate stick with a circular tip. The drawn FIG. 39b' is
converted into a figure signal. After drawing the figure, the user
touches the registering button 39d, and then the figure signal is
captured. Then, the display of the LCD 18 is returned to the password
log-in screen 36. The user erroneously selects and displays the
figure input screen 39 on the LCD 18, then, touches the cancel button
39c, and returns the display of the LCD 18 to the password log-in
screen 36.
[0105] On the password log-in screen 36, the user touches the log-in
button 36h so as to compare the figure signal captured on the figure
input screen 39 with the figure signal of the user which is set
in advance. The microcomputer 16 confirms the user password by the
user touching the log-in button 36h. When the password matches the
registered password comprising the figure, the photographing using
the function of the photographing operation permitted to the user
can be executed.
[0106] As mentioned above, the camera 10 according to the embodiment
of the present invention can set a plurality of types of passwords
including the character, figure, voice, and video face so as to
confirm the user including the owner. Further, the user can be confirmed
more strictly by combining the passwords, e.g., the character and
the figure, the character and the voice, and the character and face
video image. Therefore, the camera 10 does not easily enable the
change or deletion of the user registration including the owner.
[0107] The camera 10 is not operated upon losing the password of
the owner and the password of the user other than the owner described
with reference to FIGS. 2 to 4 or by losing the password set to
the camera 10 due to any reason.
[0108] Meanwhile, the camera 10 comprises a CD-ROM having a program
for writing and recording the video data recorded to the recording
medium 17 to another recording medium such as a CD or DVD by using
a personal computer.
[0109] Then, the camera 10 further comprises a user resetting program
for resetting the camera 10 to the registering state of the owner
and the owner other than the owner in the initial setting state,
in addition to the program for writing and recording the video data
of the CD-ROM to a CD or DVD. The user resetting program arranged
to the CD-ROM returns the camera 10 to the state for resetting and
registering the owner and the user via the personal computer when
the password of the camera 10 is lost or the password set to the
camera 10 is lost due to any reason.
[0110] Having described the preferred embodiment of the invention
referring to the accompanying drawings, it should be understood
that the present invention is not limited to the precise embodiment
and various changes and modifications thereof could be made by one
skilled in the art without departing from the spirit or scope of
