Digital Camera Patent Description
TECHNICAL FIELD OF THE INVENTION
[0001] This invention relates to a stroboscopic flash device comprising
at least two stroboscopic flash units attached to a front end of
a lens barrel of a digital camera and more particularly to a stroboscopic
flash device adapted to be able to set the optimum direction (posture)
of the stroboscopic flash units relative to every photographic part
of an object.
BACKGROUND OF THE INVENTION
[0002] Lately, a patient's whole body, its upper half of the body,
its face and its whole mouth or its part are taken a photograph
of by using a digital camera for the purpose of dentistry medical
treatment. In this manner, when the photographic object having various
sizes over a wide range from a small part of the object to a whole
thereof should be taken the photograph of, it is required to uniformly
irradiate a light to every part of the photographic object by adjusting
the position of the stroboscopic flash units relative to every photographic
part of the object.
[0003] In order to take a stroboscopic flash photograph of the
object for such a purpose, the stroboscopic flash units may be desirably
disposed at least on both sides of the lens barrel of the digital
camera so as to uniformly irradiate the light to the photographic
object.
[0004] There has been known by JU 57-182728A a stroboscopic flash
device adapted to be able to adjust the position thereof so as to
irradiate the light from the stroboscopic flash units from various
angles.
[0005] This prior stroboscopic flash device comprises a ring-like
holder attached to a front end of the lens barrel of the camera
and stroboscopic flash holding bases holding the stroboscopic flash
units, respectively and slipperily supported on the ring-like holder.
When a pair of knobs of the stroboscopic flash unit holding bases
are forced so as to be moved in a direction where they approach
each other, the bases can be released relative to the ring-like
holder whereby the position of the stroboscopic flash units can
be adjusted in a circumferential direction.
[0006] However, since this prior stroboscopic flash device can
adjust only the circumferential position of the stroboscopic flash
units, it could not be applied to the photography of the object
having varying in the size of the photographic parts such as the
patient's whole body or its part of the mouth in the dentistry clinical
photography. Especially, the digital camera has a dynamic range
(latitude) narrower than a silver salt film camera and therefore
the digital camera is required to irradiate the light onto the photographic
object at a precise angle and with a stable optical quantity. Thus
it will be understood that the conventional stroboscopic flash unit
position adjustment used in the stroboscopic flash device for the
silver salt film camera could not be used for the digital camera
as it is.
[0007] Moreover, since the photographer sets the posture of the
stroboscopic flash units depending on self experiential intuition,
considerable skill was required for obtaining the optimal stroboscopic
flash setup position for every photographic part of the object.
Furthermore, a delicate position deflection tends to occur in the
position setup for every setup even if it is an expert and therefore,
a fixed posture was not always able to be imparted to the stroboscopic
flash units, some deviation might possibly arise in the picture
photography.
SUMMARY OF THE INVENTION
[0008] Accordingly, it is a principal object of the invention to
provide a stroboscopic flash device for a digital camera adapted
to more easily set the optimum posture of stroboscopic flash units
relative to every photographic part of an object.
[0009] It is another object of the invention to provide a stroboscopic
flash device for a digital camera adapted to set the optimum posture
of stroboscopic flash units relative to every photographic part
of an object without any high skill.
[0010] In accordance with a feature of the invention, there is
provided a stroboscopic flash device for a digital camera including
a ring-like holder removably attached to a lens barrel of a camera
body of the digital camera and a plurality of stroboscopic flash
unit holding bases to hold a plurality of stroboscopic flash units,
respectively and comprising a circumferential position adjustment
mechanism to adjust a circumferential position of the stroboscopic
flash unit holding bases in a circumferential direction of the ring-like
holder along the ring-like holder, characterized by further comprising
an upward and downward position adjustment mechanism to adjust an
upward and downward position of a flash face of the stroboscopic
flash units by swinging the stroboscopic flash units about an axis
perpendicular to the base surface of the stroboscopic flash unit
holding bases and a rightward and leftward position mechanism to
adjust a rightward and leftward position of the flash face of the
stroboscopic flash units by swinging the stroboscopic flash units
about an axis parallel to the base surface of the stroboscopic flash
unit holding bases.
[0011] In the stroboscopic flash device of the invention, the circumferential
position adjustment mechanism, the upward and downward position
adjustment mechanism and the rightward and leftward position adjustment
mechanism may preferably include click stop means to resiliently
fix the optimum stroboscopic setup position relative to a photographic
part of an object to be photographed.
[0012] This click stop means may typically comprises a plunger
attached to one of two members relatively moved to each other and
having a ball resiliently protruding therefrom and engagement holes
provided in the other member and with which the ball of the plunger
is to be engaged.
[0013] In the stroboscopic flash device of the invention, the circumferential
position adjustment mechanism, the upward and downward position
adjustment mechanism and the rightward and leftward position adjustment
mechanism may preferably include position indication means to indicate
the optimum stroboscopic flash setup position of the respective
position adjustment mechanism relative to every photographic part
of the object.
[0014] This position indication means may comprise a pointer provided
a movable part of the respective mechanism and indication parts
provided at a fixed part of the respective mechanism to correspond
to the pointer at the optimum position of the stroboscopic flash
units relative to every photographic part of the object. The position
indication means may indicate the corresponding position by color
distinction.
[0015] In this manner, since the stroboscopic flash device of the
invention is adapted to adjust the position of the stroboscopic
flash units in a circumferential direction, an upward or downward
direction and a rightward or leftward direction, the optimum positions
of the stroboscopic flash units can be set in the circumferential
direction, the upward or downward direction and the rightward or
leftward direction for every photographic part of the object whereby
the predetermined posture of the stroboscopic flash units can be
obtained.
[0016] Especially, with the optimum stroboscopic flash position
previously known for the respective position adjustment mechanisms
indicated, the circumferential, upward or downward and rightward
or leftward optimum positions of the stroboscopic flash units are
set in accordance with the indication for every photographic part
of the object whereby the optimum posture of the stroboscopic flash
units can be easily obtained.
[0017] With the optimum stroboscopic flash unit setup positions
relative to the photographic part of the object resiliently fixed
by the click stop means, since the optimum setup positions of the
stroboscopic flash units can be promptly detected, the operation
of photographic picture for the dentistry medical treatment can
be more effectively accomplished.
[0018] The optimum positions of the stroboscopic flash units can
be positively set by selecting the indication parts provided on
the fixed parts of the respective position adjustment mechanisms
in correspondence with the pointer provided on the movable parts
of the respective position adjustment mechanisms and therefore the
optimum position (posture) of the stroboscopic flash units can be
easily confirmed.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0026] The invention will now be described with reference to accompanying
drawings. FIG. 1 illustrates a digital camera 12 having a stroboscopic
flash device 10 constructed in accordance with one embodiment form
of the invention. The digital camera 12 comprises a camera body
14 including a plurality of lens barrels provided at a front thereof
and having a zoom function.
[0027] The stroboscopic flash device 10 comprises a ring-like holder
16 removably attached to the lens barrel 14A of the camera body
14 and a plurality of (in the illustrated embodiment, two) stroboscopic
flash unit holding bases 20 and 20' to hold a plurality of (in the
illustrated embodiment, two) stroboscopic flash units 18 and 18',
respectively through various position adjustment mechanisms described
later.
[0028] The stroboscopic flash units 18 and 18' are connected by
cables 82 and 82' to a mount type multistage stroboscopic flash
regulator 80 on which the camera body 14 is securely mounted. In
FIG. 1, a reference numeral 84 designates a screw rotating knob
for securing the camera body 14 to a case 86 of the regulator 80
in a threaded engagement manner.
[0029] The ring-like holder 16 may be removably attached to a front
end of the lens barrel 14A by conventional means. The typical attachment
means may have the same construction as that for a ring-like stroboscopic
flash holder as disclosed in JP 2002-122936A. The detailed construction
of the attachment means will be omitted because it is not a gist
of the invention.
[0030] As shown in FIG. 3, the ring-like holder 16 may comprise
an attachment ring 22 attached to the lens barrel 14A in a threaded
engagement manner, a flame body 26 having a flange 24 and a attachment
flange 30 to be secured to a non-flange side of the flame body 26
through a spacer ring 28. The flange 24 is secured to the attachment
ring 22 by screws 32 (also see FIG. 2) extending through the flange
24 and threaded into not shown threaded holes in the attachment
ring 22.
[0031] The stroboscopic flash device 10 is provided with a circumferential
position adjustment mechanism 34 to adjust the position of the stroboscopic
flash units 18 and 18' together with the ring-like holder 16 in
a circumferential direction of the ring-like holder 16, an upward
and downward position adjustment mechanism 36 to adjust the position
of the stroboscopic flash units 18 and 18' in an upward or downward
direction and a rightward and leftward position mechanism 38 to
adjust the position of the stroboscopic flash units 18 and 18' in
a rightward or leftward direction.
[0032] The circumferential position adjustment mechanism 34 comprises
annular grooves 24G and 30G (see FIGS. 2 and 3) formed in the inside
faces of the flanges 24 and 30 of the ring-like holders 16 and the
stroboscopic flash unit holding bases 20 and 20' on both sides thereof
have arc-like slider portions 20S and 20'S to be engaged into the
annular grooves 24G and 30G to be slipperily held in the ring-like
holder 16. Thus, it will be understood that the stroboscopic flash
units 18 and 18' held in the stroboscopic flash unit holding bases
20 and 20' through the upward and downward position adjustment mechanism
36 and the rightward and leftward position mechanism 38 as later
described can move along the annular grooves 24G and 30G in the
ring-like holder 16 in the circumferential direction. In FIGS. 2
and 3, a reference numeral 40 designates stops to limit the circumferential
movement of the stroboscopic flash unit holding bases 20 and 20'
beyond the predetermined critical circumferential position.
[0033] As shown in FIG. 4, the upward and downward position adjustment
mechanism 36 comprises an upward and downward position adjustment
member 44 in the form of circular flame rotationally held by a rotary
shaft 42 at the centers of the stroboscopic flash unit holding bases
20 and 20' so as to swing about an axis perpendicular to the flat
surfaces 20F and 20'F (also see FIG. 2) of the stroboscopic flash
unit holding bases 20 and 20' and holding the stroboscopic flash
units 18 and 18' through the rightward and leftward position mechanism
38 later described. Thus, it will be understood that the flash faces
of the stroboscopic flash units 18 and 18' are adjusted in their
positions in the upward or downward direction by the rotation of
the upward and downward position adjustment member 36.
[0034] Also, as shown in FIG. 4, the rightward and leftward position
adjustment mechanism 38 comprises a rightward and leftward position
adjustment member 48 rotationally held by a rotary shaft 46 between
opposing brackets 44B of the upward and downward position adjustment
member 44 so as to swing about an axis parallel to the flat surfaces
20F and 20'F of the stroboscopic flash unit holding bases 20 and
20' and holding the stroboscopic flash units 18 and 18' as later
described. Thus, it will be understood that the flash faces of the
stroboscopic flash units 18 and 18' are adjusted in their positions
in the rightward or leftward direction by the rotation of the rightward
and leftward position adjustment member 48.
[0035] As shown in FIG. 4, there is provided stroboscopic flash
unit attachment means 50, which comprises a female type accessory
shoe 52 secured by screws to an outer face of the rightward and
leftward position adjustment member 48 and a male type accessory
shoe 54 resiliently inserted into and held by the female type accessory
shoe 54 and the stroboscopic flash units 18 and 18' are attached
to the male type accessory shoe 54 by conventional means. In FIG.
4, a reference numeral 53 designates a leaf spring attached to the
female type accessory shoe 52 to resiliently hold the male type
accessory shoe 54.
[0036] In this manner, the stroboscopic flash units 18 and 18'
can be set having the optimum posture relative to the photographic
part of the object by the circumferential position adjustment mechanism
34, the upward and downward position adjustment mechanism 36 and
the rightward and leftward position mechanism 38. Although FIG.
4 shows the position adjustment mechanisms 34, 36 and 38 only on
the side of the stroboscopic flash unit holding bases 20, those
on the side of the stroboscopic flash unit holding bases 20' are
also constructed in the same manner.
[0037] The circumferential position adjustment mechanism 34, the
upward and downward position adjustment mechanism 36 and the rightward
and leftward position mechanism 38 include click stop means 60 to
fix the position of the stroboscopic flash units 18 and 18' at the
optimum stroboscopic flash setup position relative to the photographic
part of the object.
[0038] The click stop means 60 may typically comprises a plunger
62 attached to one of two members relatively moved to each other
for every position adjustment mechanism and having a ball 62B resiliently
protruding therefrom by a spring 62S and engagement holes 64 provided
in the other member and with which the ball 62B of the plunger 62
is to be engaged.
[0039] More particularly, in the illustrated embodiment, the plunger
62 is embedded in the stroboscopic flash unit holding bases 20 and
20' (one of the members) of the circumferential position adjustment
mechanism 34 on one of the sides thereof so that the ball 62B protrudes
from one of the side faces thereof while the engagement holes 64
are provided in the flange 24 (the other member) of the ring-like
holder 16 in a circumferentially spaced manner. Similarly, the plunger
62 is embedded in the wall of the upward and downward position adjustment
member 44 of the upward and downward position adjustment mechanism
36 facing the stroboscopic flash unit holding bases 20 and 20' so
that the ball 62B protrudes from the wall of the upward and downward
position adjustment member 44 while the engagement holes 64 are
provided in the stroboscopic flash unit holding bases 20 and 20'
(the other member) on the surface thereof in a circumferentially
spaced manner. Also similarly, the plunger 62 is embedded in the
upper and lower portions (one of the members) of the upward and
downward position adjustment member 44 on the inside face thereof
so that the ball 62B protrudes from the inside face thereof while
the engagement holes 64 are provided in the upper and lower wall
(the other member) of the rightward and leftward position adjustment
member 48 of the rightward and leftward position adjustment mechanism
38 in a manner spaced in the direction of arc.
[0040] The click stop means 60 of these position adjustment mechanisms
34, 36 and 38 is so set that the ball 62B is engaged in one of the
engagement holes 64 corresponding to the optimum position of the
stroboscopic flash units 18 and 18' where the flash faces of the
stroboscopic flash units 18 and 18' are most appropriately faced
to the photographic part of the object in accordance with the size
thereof.
[0041] The circumferential position adjustment mechanism 34, the
upward and downward position adjustment mechanism 36 and the rightward
and leftward position mechanism 38 include position indication means
70 to indicate the optimum stroboscopic flash position relative
to every photographic part of the object.
[0042] As shown in FIG. 6, this position indication means 70 may
comprise a pointer 72 provided on either of the movable and fixed
parts of the respective position adjustment mechanisms 34, 36 and
38 and a plurality of indication parts 74 provided at the other
part of the respective position adjustment mechanisms 34, 36 and
38 to correspond to the pointer at the optimum position of the stroboscopic
flash units 18 and 18' relative to every photographic part of the
object.
[0043] More particularly, as shown in FIG. 6A, the pointer 72 is
formed at the edge of the base surfaces 20F and 20'F (movable part)
of the stroboscopic flash unit holding bases 20 and 20' of the circumferential
position adjustment mechanism 34 while the indication parts 74 are
formed on the flange 30 (fixed part) of the ring-like holder 16
in accordance with the optimum circumferential positions of every
photographic parts of the object. Similarly, as shown in FIG. 6B,
the pointer 72 is formed at the longitudinal edge of the base surfaces
20F and 20'F (fixed part) of the stroboscopic flash unit holding
bases 20 and 20' while the indication parts 74 are formed at the
edges of the circumferential face (movable part) of the upward and
downward position adjustment member 44 of the upward and downward
position adjustment mechanism 36 in accordance with the optimum
upward or downward positions of every photographic parts of the
object. Also similarly, as shown in FIG. 6C, the pointer 72 is formed
at the end face (movable part) of the rotary shaft 46 of the rightward
and leftward position adjustment mechanism 38 while the indication
parts 74 are formed at the bracket 44B (fixed part) of the upward
and downward position adjustment member 44 in accordance with the
optimum rightward or leftward positions of every photographic parts
of the object.
[0044] The indication parts 74 may distinguish the optimum positions
relative to every photographic parts of the object by color distinction.
For example, in the dentistry clinical treatment, the indication
part 74 for the optimum position relative to a patient's face as
the photographic part may be of blue color (74B), the indication
part 74 for the optimum position relative to the patient's whole
mouth as the photographic part may be of red color (74R) and the
indication part 74 for the optimum position relative to the patient's
mouth parts as the photographic part may be of yellow color (74Y).
Thus, it will be understood that the optimum positions relative
to various photographic parts of the object can be distinguished
by the color indication.
[0045] In case where the stroboscopic flash device of the invention
may be used for photography of the dentistry clinical treatment,
whenever the photographic parts varies from the patient's face through
its mouth to its mouth part, the circumferential position of the
two stroboscopic flash units 18 and 18' can be adjusted in the upward
direction from the position apart by 180 degree on both sides of
the ring-like holder 16 to the direction where they get gradually
closer to each other every 25 degree. Similarly, whenever the photographic
parts varies in the same manner, the upward or downward position
of the flash faces of the two stroboscopic flash units 18 and 18'
can be adjusted every 25 degree in the upward or downward direction
from the horizontal position. Also similarly, whenever the photographic
parts varies in the same manner, the rightward or leftward position
of the flash faces of the two stroboscopic flash units 18 and 18'
can be adjusted every 25 degree in the inside direction from the
position where the flash faces are faced in a front direction.
[0046] Thus, in case where the photographic part of the object
is the patient's ace, for example, as the respective position adjustment
mechanism 34, 36 and 38 adjust the position of the stroboscopic
flash units 18 and 18' until the pointers 72 of the position indication
means 70 of all the position adjustment mechanism 34, 36 and 38
correspond to the "blue" indication parts 74B, the stroboscopic
flash units 18 and 18' are set at the posture suitable for taking
a photograph of the whole face of the patient. Similarly, in case
where the photographic part of the object is the patient's mouth,
as the respective position adjustment mechanism 34, 36 and 38 adjust
the position of the stroboscopic flash units 18 and 18' until the
pointers 72 of the position indication means 70 of all the position
adjustment mechanism 34, 36 and 38 correspond to the "red"
indication parts 74R, the stroboscopic flash units 18 and 18' are
set at the posture suitable for taking a photograph of the whole
mouth of the patient. Also similarly, in case where the photographic
part of the object is the patient's part of mouth, as the respective
position adjustment mechanism 34, 36 and 38 adjust the position
of the stroboscopic flash units 18 and 18' until the pointers 72
of the position indication means 70 of all the position adjustment
mechanism 34, 36 and 38 correspond to the "yellow" indication
parts 74Y, the stroboscopic flash units 18 and 18' are set at the
posture suitable for taking a photograph of the part of the mouth
of the patient. In this manner, the dentist can accomplish the optimum
stroboscopic flash photography in accordance with the photographic
part of the object even though the dentist is not an expert of use
of the digital camera.
[0047] Although, in the illustrated embodiment, the respective
position adjustment mechanisms are adapted to set the position of
the stroboscopic flash units by the pointer indicating the color-distinction
indication parts 74R, 74B and 74Y, the position adjustment mechanism
may set the stroboscopic flash units so as to properly select their
posture without any position indication means. Otherwise, even though
there are provided the position indication means, in case where
a photographic object other than the object for which the position
indication means is previously determined or the photographic part
or parts of the object other than those for which the position indication
means is previously determined should be taken a photograph of,
the respective position adjustment mechanism can adjust the position
of the stroboscopic flash units without using the position indication
means.
[0048] Although, in the aforementioned description, there is explained
the case where the digital camera 12 is used for the picture photography
of dentistry clinical treatment, it should be understood that the
stroboscopic flash device 10 of the invention may be applied to
the digital camera used for application other than the dentistry
clinical treatment.
[0049] According to the invention, since the plurality of the stroboscopic
flash units can be set at the optimum position in the circumferential,
upward or downward and rightward or leftward directions relative
to every photographic part or parts of the object, the standardized
optimum stroboscopic flash posture can be easily obtained for every
photographic part of the object, which improves the availability
on industries.
[0050] Although one preferred embodiment of the invention has been
described and illustrated with reference to the accompanying drawings,
it will be understood by those skilled in the art that it is by
way of example, and that various changes and modifications may be
made without departing from the spirit and scope of the invention,
which is d only to the appended claims. |
