Digital Camera Patent Description
BACKGROUND OF THE INVENTION
[0001] The invention relates generally to consumer electronics,
and more particularly to digital cameras with a detachable display
used as a remote control to operate the camera.
[0002] Digital cameras, both video and still, have been very popular
nowadays. People can take the advantages of digital cameras to record
favorite scenes and pictures and share them with others. A traditional
digital camera usually requires a person to act as the photographer
to hold and operate the camera to take video or still pictures on
other people or subjects. In the case where one would like to take
video or pictures of himself, he would need to make an estimate
of the focus of the camera lens and then use a remote control unit
of the camera to record. Oftentimes, such an estimate is very rough
and the subject in the resulting video or picture is not in a desired
position. Further, it involves a number of adjustments in order
to obtain acceptable video or pictures. Making the adjustments back
and forth gives much inconvenience and hassles to users such that
this feature of the camera is rarely used by many users.
[0003] Therefore, there is a need for an improved digital camera
that allows a user to be able to conveniently and accurately record
video or pictures of the user himself.
SUMMARY OF THE INVENTION
[0004] The present invention provides an improved digital camera
that enables a user to conveniently and accurately record video
or pictures of the user himself. The invention is applicable to
both digital video and still cameras.
[0005] In one embodiment of the invention, a digital camera comprises
a camera body and a display panel detachably connected to the camera
body. The display panel includes a remote control circuit that is
configured to wirelessly operate the camera, so that a user can
record any contents seen in the display panel.
[0006] In another embodiment of the invention, the camera further
includes a motor attached to the camera body, and the remote control
circuit controls the motor to focus the lens on a desired subject.
The remote control circuit includes a wireless communication interface
that supports at least one of the following protocols: Bluetooth,
Zigbee, IEEE 802.11 and infrared.
[0007] Other objects and attainments together with a fuller understanding
of the invention will become apparent and appreciated by referring
to the following description and claims taken in conjunction with
the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The invention is explained in further detail, and by way
of example, with reference to the accompanying drawings wherein:
[0009] FIG. 1 illustrates a digital camera in accordance with one
embodiment of the invention;
[0010] FIG. 2 shows a display panel in accordance with one embodiment
of the invention; and
[0011] FIG. 3 is a functional block diagram of a display panel
in accordance with one embodiment of the invention.
[0012] Throughout the drawings, the same reference numerals indicate
similar or corresponding features or functions.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] FIG. 1 illustrates a digital camera 10 in accordance with
one embodiment of the invention. Camera 10 includes a camera body
12, a detachable display panel 20, e.g., a LCD panel, and a motorized
unit 22. Display panel 20 includes remote control circuitry for
wirelessly controlling the operation of camera 10 when it is detached
from the camera body. When it is attached to the camera body, display
panel 20 functions as a normal display and camera 10 returns to
a normal operation mode. Motorized unit 22 includes a small motor
that can change the direction of the camera body to focus the camera
lens on a subject, in response to control signals wirelessly received
from display panel 20.
[0014] FIG. 2 shows display panel 20 in accordance with one embodiment
of the invention. Display panel 20 has a LCD display 24 and a plurality
of control buttons 26 for remotely controlling the operation of
camera 10, e.g., to record video and play back the video previously
taken. LCD display 24 may be a touch screen, so that control buttons
26 may be implemented on the display itself.
[0015] FIG. 3 is a functional block diagram of display panel 20
in accordance with one embodiment of the invention. As illustrated,
display panel 20 includes a wireless communication interface 32,
a wireless communication control unit 36, a micro control unit 42,
a LCD display and control unit 46 and a memory 52. Display panel
also includes a rechargeable battery 56 and a connector 62 for connecting
to camera body 12. Wireless communication interface 32 can support
various protocols, e.g., Bluetooth, Zigbee, IEEE 802.11, infrared,
etc.
[0016] When a user wants to record video of himself, he can place
camera 10 on a tripod and detach display panel 20 from camera body
12. Then he can operate the remote control buttons on the display
panel to focus the lens on himself. If he likes what he sees on
the display, he can simply record it. He may also make appropriate
adjustments by changing the direction and level of the camera lens
and then record it. He may even move around and control the camera
lens to focus on himself while he is moving around and record the
whole event. Alternatively, the user may use camera 10, as a monitoring
system, to monitor movable subjects, e.g., a child, a pet, etc.
In this way, a user can accurately record himself or anything without
having another dedicated person physically holding and operating
the camera.
[0017] In the above, a video camera is used as an example to illustrate
one embodiment of the invention. In another embodiment of the invention,
a still digital camera may be remotely controlled by a detachable
display panel in a similar way.
[0018] While the invention has been described in conjunction with
specific embodiments, it is evident that many alternatives, modifications
and variations will be apparent to those skilled in the art in light
of the foregoing description. Accordingly, it is intended to embrace
all such alternatives, modifications and variations as fall within
the spirit and scope of the appended claims.
