Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing apparatus, and more particularly, to a photographing apparatus for photographing a personal identification photograph.

[0002]

2. Description of the Related Art A photographing device for photographing an identification photograph for personal identification photographs a photograph of the owner's face which is integrally printed on a personal identification medium such as a license or an employee ID card.

[0003] In such a photographing apparatus, it is necessary to take care that the size and position of the face in the human image of the subject person become a certain ratio (ideal state) in the photographed image. That is, it is necessary to adjust the position of the face in the human image so as to be located substantially at the center in a predetermined frame of the personal identification medium. The ideal state at this time is a state where the face position is arranged in the frame such that a predetermined space is secured from the top of the head to the frame, and a space approximately equal to both sides of the face is secured.

Therefore, it is necessary to perform an adjustment operation for adjusting the position of the face of the subject person before photographing. In this adjustment work, particularly, the frequency of vertical height adjustment for the height variation of the subject person, that is, adjustment of the subject person in the vertical direction is extremely high. As a reference for height adjustment in the vertical direction, for example, adjustment is performed so that the chin position of the subject person is arranged at the center in the frame.

Conventionally, height adjustment in the vertical direction has been performed manually by a staff member. That is, the clerk adjusts the height by swinging and rotating the photographing camera itself in the vertical direction or by moving it in parallel in the vertical direction while checking the face image of the subject person photographed by the photographing camera of the photographing device. .

[0006] Each photographing camera itself is moved by directly manually operating a mechanism system which is movable while holding the photographing camera, or by operating a motorized mechanism or the like with a control lever.

When continuously photographing a large number of subjects, manual adjustment of the height by the attendant is a complicated operation.
In addition to increasing the burden on the staff, there is a possibility that the imaging efficiency will be extremely reduced. Therefore, there is a method in which such height adjustment is automated.

For example, there is a method of detecting the position of the face of the subject person, calculating the amount of movement to be adjusted, and adjusting the height by moving the photographing camera itself up and down by an electric mechanism or the like.

When the face of the subject person is photographed with a digital camera or the like and the face image can be processed as image data, the photographing camera is fixed at an average height position and the height of the subject person varies in advance. In consideration of the above, there is a method in which a large area is photographed, the face position of the subject person is detected, and a necessary area is cut out from the photographed image data by image processing.

[0010]

However, the above-described method has the following problems.

That is, there is a limit to speeding up in the method of moving the photographing camera itself in the vertical direction. This may be caused by insufficient driving force of the driving source with respect to the inertia of the camera. Even when a high-power drive source is used to compensate for the lack of driving force, moving the camera at high speed causes the camera itself and the lens forming the optical system of this camera to vibrate. Therefore, in order to capture a stable image, a sufficiently long vibration end time is required. For these reasons, there is a problem that it is difficult to increase the speed and it is not possible to improve the shooting efficiency.

In the method in which a large area is photographed in consideration of the variation in the height of the subject person and a necessary area is cut out, a part of the first image data is enlarged for the cut out image data. Therefore, there arises a problem that the resolution is reduced and the quality of the image is deteriorated. In order to compensate for the degradation in image quality, it is necessary to use a high-precision and high-resolution photographing camera, which causes a problem of increased cost.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems, and has as its object to reduce the burden on the staff and to provide an imaging apparatus capable of efficiently performing imaging without increasing costs and lowering resolution. Is to provide.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a photographing apparatus according to an embodiment of the present invention; The photographing device 50 is for photographing an identification photograph for personal identification, and photographs a photograph of the face of the owner, that is, the subject person 100, which is integrally printed on a personal identification medium such as a license or an employee ID card.

As shown in FIG. 1, a photographing device 50 includes a photographing camera 1 as photographing means, a reflecting mirror 6, a reflecting mirror swinging mechanism 5 as driving means, and a control section 7 as adjusting means. , A display unit 8 as display means, an operation panel 9, and a lighting device 51 as lighting means.

The photographing camera 1 is, for example,
Is a CCD camera that generates image data of a human image by photographing the image of the subject. The optical axis of the camera including the lens system is bent by the reflecting mirror 6 and is disposed so as to face the subject person 100. At the time of photographing, the subject person 100 is seated on the chair 53, but assuming a standing state, it may be arranged at a position corresponding to the standing state.

However, since the difference in sitting height is smaller than the difference in height, it is possible to reduce the adjustment range in the vertical direction, that is, in the vertical direction of the person image, when photographing the seated subject person 100. It is possible.

The reflecting mirror 6 reflects the person image of the subject person 100 so as to guide the person image to the photographing camera 1. This reflecting mirror 6
The optical axis is configured to be rotatable in a vertical direction about a bending position, that is, a reflection position. Since the optical axis of the photographing camera 1 corresponds to the position of a rotatable fulcrum on the reflecting surface of the reflecting mirror 6, even if the reflecting mirror 6 pivots, the optical axis of the photographing camera 1 and the reflection of the reflecting mirror 6 are not reflected. The relationship with the surface is always kept constant.

By bending the optical axis of the photographing camera 1 by the reflecting mirror 6, even if it is necessary to secure a sufficient distance between the subject person 100 and the photographing camera, the apparatus can be enlarged in the depth direction. Thus, the size of the main body of the photographing device 50 can be reduced. In the embodiment shown in FIG. 1, for example, the distance between the subject person 100 and the photographing device 50 is about 1 m.

The reflector swing mechanism 5 pivots the reflector at least in the vertical direction of the human image with the bending position of the optical axis on the reflecting surface of the reflector 6 as a fulcrum. By this rotation operation, the optical axis of the photographing camera 1 reflected by the reflection surface of the reflection mirror 6 rotates at twice the rotation angle of the reflection mirror 6.

For example, as shown in FIG. 2A, when the reflecting mirror 6 is rotated a / 2 degrees around the fulcrum 6a, the distance between the reflecting mirror 6 of the photographing camera 1 and the subject person 100 is increased. Is rotated a degrees. In this embodiment, based on the case where the optical axis of the photographing camera 1 is bent by 90 degrees, a = ±
If the reflecting mirror can be rotated by 4 degrees, that is, ± 2 degrees in terms of the rotation angle of the reflecting mirror, it is possible to cope with a subject person having an approximate height.

On the other hand, as shown in FIG. 2B, when the optical axis of the photographing camera 1 is not bent without a reflecting mirror, the optical axis between the reflecting mirror 6 of the photographing camera 1 and the subject person 100 is changed. Is required to rotate the photographing camera 1 itself by a degrees.

When comparing the two, turning the reflecting mirror 6 that bends the optical axis of the photographing camera 1 has a lighter rotation object and higher rigidity than turning the photographing camera 1 itself. Also,
Since the rotation range is small, even with a small driving force, the adverse effects of the vibration are extremely small, and the driving can be performed at high speed.

The reflector swing mechanism 5 is provided with a manual operation lever 5a, which allows the display unit 8 to manually correct the display image of the subject who has been automatically adjusted as described later. It is possible.

FIGS. 3 to 5 are views showing examples of the structure of the reflector swing mechanism 5. As shown in FIGS.

The first reflector swing mechanism 5 includes a frame 13 for holding the reflector, a cam follower 14 integrally formed at one end of the frame 13, and a cam follower urged by a spring (not shown). A cam 15 against which 14 is pressed,
And so on. The frame 13 is configured to be rotatable around a fulcrum 6 a on the reflecting surface of the reflecting mirror 6.

When the cam 15 is rotated by a rotary drive source such as a pulse motor, the cam follower 14 integrated with one end of the frame 13 accurately follows the cam shape accompanying the rotation. Thereby, the reflecting mirror 6 held by the frame 13 rotates around the fulcrum 6a.

As shown in FIG. 3A, in the reference state, the angle θ of the optical axis bent at the fulcrum of the reflecting mirror 6 is set to a predetermined angle.

When the sitting height of the subject person 100 is high,
As shown in FIG. 3B, the rotation drive source is driven by the control of the control unit 7, and the cam 15 has a smaller direction in the direction of the arrow in the figure, that is, the distance between the center axis of the cam 15 and the cam follower 14. Rotate in the direction. Thus, the reflecting mirror 6 held by the frame 13 is rotated about the fulcrum 6a in the direction of the arrow in the drawing. Thus, the angle θ of the optical axis becomes larger than the predetermined angle shown in FIG. That is,
The reflecting surface of the reflecting mirror 6 is moved upward, so that a person image of the subject person 100 having a high sitting height can be captured.

When the sitting height of the subject person 100 is low,
As shown in FIG. 3C, the rotation drive source is driven under the control of the control unit 7, and the cam 15 has a larger direction in the direction of the arrow in the figure, that is, the center axis of the cam 15 and the cam follower 14. Rotate in the direction. Thus, the reflecting mirror 6 held by the frame 13 is rotated about the fulcrum 6a in the direction of the arrow in the drawing. Thus, the angle θ of the optical axis becomes smaller than the predetermined angle shown in FIG. That is,
The reflecting surface of the reflecting mirror 6 is moved downward, so that a person image of the subject person 100 having a low sitting height can be captured.

According to the mechanism shown in FIGS. 3A to 3C, for example, even if there is a shooting distance of 1 m and a difference in sitting height of 50 mm, the vertical movement time is set to 50 msec or less. Can be. As described above, with this mechanism, it is possible to secure the stop position accuracy and the repeat position accuracy at high speed and sufficiently.

The second reflector swing mechanism 5 includes a reflector 6
And a piezoelectric element 16 for rotating the reflecting mirror 6 about a fulcrum 6a.

When the charge of the piezoelectric element 16 is controlled, the piezoelectric element 16 expands and contracts, and the amount of displacement is converted into the rotation angle of the reflecting mirror 6.

As shown in FIG. 4A, in the reference state, the angle θ of the optical axis bent at the fulcrum of the reflecting mirror 6 is set to a predetermined angle.

When the sitting height of the subject person 100 is high,
As shown in FIG. 4B, the electric charge of the piezoelectric element 16 is controlled by the control of the control unit 7, and the piezoelectric element 16 contracts. This contraction amount is converted into a rotation angle of the reflecting mirror 6.
Thereby, the reflecting mirror 6 is rotated about the fulcrum 6a in the direction of the arrow in the figure. As a result, the angle θ of the optical axis becomes larger than the predetermined angle shown in FIG. That is, the reflecting surface of the reflecting mirror 6 is moved upward, and it becomes possible to capture a human image of the subject person 100 having a high sitting height.

When the sitting height of the subject person 100 is low,
As shown in FIG. 4C, the electric charge of the piezoelectric element 16 is controlled by the control of the control unit 7, and the piezoelectric element 16 is expanded. This amount of extension is converted into a rotation angle of the reflecting mirror 6.
Thereby, the reflecting mirror 6 is rotated about the fulcrum 6a in the direction of the arrow in the figure. As a result, the angle θ of the optical axis becomes smaller than the predetermined angle shown in FIG. That is, the reflecting surface of the reflecting mirror 6 is moved downward, so that a person image of the subject person 100 having a low sitting height can be captured.

According to the mechanism shown in FIGS. 4A to 4C, the number of parts of the mechanism can be reduced.
It is possible to reduce costs.

The third reflector swing mechanism 5 includes a reflector 6
And a worm gear 18 attached to a rotating shaft of a motor 19.
The worm wheel 17 is configured to be rotatable around a fulcrum 6 a on the reflecting surface of the reflecting mirror 6.

When the motor 18 rotates, the worm gear 1
9 is driven to rotate, and the reflecting mirror 6 held by the worm wheel 17 rotates about the fulcrum 6a.

As shown in FIG. 5A, in the reference state, the angle θ of the optical axis bent at the fulcrum of the reflecting mirror 6 is set to a predetermined angle.

When the sitting height of the subject person 100 is high,
As shown in FIG. 5B, under the control of the control unit 7, the motor 19 is driven and the worm gear 18 is rotated. Thus, the reflecting mirror 6 held on the worm wheel 17
Is turned around the fulcrum 6a in the direction of the arrow in the figure.
As a result, the angle θ of the optical axis becomes larger than the predetermined angle shown in FIG. That is, the reflecting surface of the reflecting mirror 6 is moved upward, and it becomes possible to capture a human image of the subject person 100 having a high sitting height.

When the sitting height of the subject person 100 is low,
As shown in FIG. 5C, under the control of the control unit 7, the motor 19 is driven, and the worm gear 18 is rotated. Thus, the reflecting mirror 6 held on the worm wheel 17
Is turned around the fulcrum 6a in the direction of the arrow in the figure.
As a result, the angle θ of the optical axis becomes smaller than the predetermined angle shown in FIG. That is, the reflecting surface of the reflecting mirror 6 is moved downward, so that a person image of the subject person 100 having a low sitting height can be captured.

The control unit 7 processes image data of a person image of the subject person 100 photographed by the photographing camera 1.
The control unit 7 includes an image inversion processing unit 2 as an inversion unit.
And a face position detection unit 3 as face position detection means, and a reflector swing mechanism control unit 4 as adjustment means.

The image inversion processing unit 2 inverts the left and right of the image data of the human image generated by the photographing camera 1 to form a mirror image of the human image. That is, in the image of the person image captured by the camera 1, the left and right of the person are inverted by the reflecting mirror 6. The image inversion processing unit 2 converts the inverted captured image into a normal image by inverting the inverted image again to form a mirror image.

The face position detection unit 3 detects a face position from the image data that has been inverted by the image inversion processing unit 2. The face position detecting unit 3 moves the reflecting mirror 6 in the vertical direction, that is, reflects the reflecting mirror 6 based on the detected face position so that the face position of the human image is in an ideal state of being arranged at a predetermined position in a predetermined frame. 6 is calculated. This ideal state is
In this state, the face position is arranged in the frame such that a predetermined space is secured between the top of the human image and the frame, and a space that is substantially equal to both sides of the face is secured.

The reflecting mirror swinging mechanism control section 4 is controlled by the reflecting mirror swinging mechanism section 5 based on the movement amount calculated by the face position detecting section 3.
To adjust the reflection angle of the reflecting mirror 6. As a result, the subject person 10 is located at a predetermined position in the frame.
It is automatically adjusted so that a face position of 0 is arranged.

For example, as shown in FIG. 1, when a part of the subject's head protrudes from a predetermined frame 105 in the subject display image 102, the reflecting mirror 6 is rotated upward to obtain a top portion. It is adjusted to an ideal state in which an appropriate space can be secured between the frame 105 and the frame 105. Further, when the position of the head of the subject person is too low in the predetermined frame 105 and an excessive space is formed between the top of the head and the frame 105, the reflecting mirror 6 is rotated downward. Is adjusted to an ideal state.

As described above, the feedback loop is formed in the control unit 7. That is, after the vertical adjustment is performed once, the subject person 100 is photographed again by the photographing camera 1 and the image data of the person image is sent to the face position detection unit 3 via the image inversion processing unit 2 and the face It is determined whether the position is located within a predetermined range of the frame 105, and if necessary, the amount of movement of the reflector is calculated, and the vertical adjustment is performed again. In this manner, the vertical adjustment of the human image is automatically performed, and the face position of the human image is adjusted so as to be arranged at a predetermined position.

The display unit 8 displays the subject display image 102 based on the image data of the human image inverted by the image inversion processing unit 2.

The operation panel 9 has various operation buttons operated by the attendant 101, and includes a photographing button for instructing start of photographing, a print button for instructing printing of a face photograph on a personal identification medium and the like.

The lighting device 51 is a chair 5 in front of the background plate 52.
The subject person 100 seated on 3 is illuminated.

In the photographing apparatus 50 described above, the chair 5
When the subject person 100 sitting on the third person is detected, the vertical adjustment of the person image is automatically performed by the feedback loop as described above.

That is, the reflection mirror 6 reflects the person image of the subject person 100 sitting on the chair 53. Camera 1
Captures a human image reflected on the reflecting mirror 6 and generates image data. The image data is sent to the control unit 7, and the image inversion processing unit 2 inverts the left and right of the human image. This image data is displayed on the display unit 8 and sent to the face position detection unit 3.

The face position detecting section 3 detects the face position from the image data of the human image and calculates the amount of movement in the vertical direction so as to achieve the ideal state. The reflector swing mechanism controller 4 controls the reflector swing mechanism 5 based on the calculated movement amount, and rotates the reflector 6 in the vertical direction.

Then, the image data of the person image photographed by the photographing camera 1 is fed back to the control section 7 again and automatically adjusted until the ideal state is achieved.

After the automatic adjustment is completed, the attendant 101
After confirming the subject display image 102 displayed on the display unit 8,
If necessary, fine adjustment is performed by operating the manual operation lever 5a of the reflector swing mechanism 5.

When the attendant 101 presses the photographing button on the operation panel 9, a human face image is photographed in a predetermined frame 105 in an ideal state or within a predetermined allowable range.

The image data of this face image is sent to the printing machine, and when the attendant 101 presses the print button on the operation panel 9, the photographed face image is printed on a predetermined frame of the personal identification medium, and the personal identification medium is printed. Media is issued.

According to the photographing apparatus as described above, since the position of the face can be adjusted at high speed, the burden on the staff can be reduced and the photographing can be performed efficiently. Further, according to this photographing apparatus, it is possible to photograph a face photograph of sufficient image quality without using a photographing camera having excessively high resolution, so that it is possible to prevent an increase in cost and a decrease in resolution. . Furthermore, according to this photographing device, since the optical axis of the photographing camera is bent by the reflecting mirror, it is possible to prevent the device from expanding in the depth direction and to achieve downsizing.

The photographing apparatus is not limited to the above-described embodiment, but can be variously modified.

The photographing apparatus 50 shown in FIG. 6 includes a dedicated camera 11 for detecting a face position in a human image of the subject person 100 in addition to the configuration described with reference to FIG.

The dedicated camera 11 has a
And detects the detected position information in the face position detecting unit 3.
Send to

The face position detecting section 3 calculates the amount of vertical movement of the reflecting mirror 6 with respect to the subject person 100 based on the position information of the face position detected by the dedicated camera 11 so as to be in an ideal state. The mirror swing mechanism controller 4 controls the reflector swing mechanism 5 based on the calculated movement amount, and the reflector swing mechanism 5 controls the reflector swing mechanism 5 based on the control of the reflector swing mechanism controller 4. Then, the reflecting mirror 6 is rotated in the vertical direction and adjusted.

In this way, the face position is automatically adjusted until the ideal state is achieved.

With the configuration as shown in FIG. 6, as in the above-described embodiment, the burden on the staff can be reduced, and the shooting can be performed efficiently without increasing the cost and lowering the resolution.

A photographing apparatus 50 shown in FIG. 7 has a construction similar to that described with reference to FIG. 1 and a top position detecting means for detecting a shadow of a person 100 and detecting a top position in a person image. As a mechanism.

This mechanism detects the sitting height of the subject person 100 sitting on the chair 53, and is constituted by an illuminating device 51 as illuminating means, an optical sensor 12 incorporated in a background plate 52, and the like. I have.

According to such a mechanism, the illuminating device 51 illuminates the seated subject person 100 and the optical sensor 12 detects the height of the shadow on the background plate 52 that is blocked by the subject person 100. I do.

The output signal from the optical sensor 12 is sent to the face position detector 3.

The face position detector 3 detects the top of the subject person 100 based on the output signal from the optical sensor 12 and determines a predetermined position between the top position and the frame based on the position information of the top. The amount of vertical movement of the reflecting mirror 6 with respect to the subject person 100 is calculated so that an ideal state in which the space can be secured is calculated.

The reflector swing mechanism controller 4 controls the reflector swing mechanism 5 based on the calculated movement amount.
The reflector swing mechanism 5 includes a reflector swing mechanism controller 4.
, The reflecting mirror 6 is rotated in the vertical direction and adjusted.

In this way, the face position is automatically adjusted until the ideal state is achieved.

With the configuration as shown in FIG. 7, as in the above-described embodiment, the burden on the staff can be reduced, and photographing can be performed efficiently without increasing the cost and lowering the resolution.

The photographing device 50 shown in FIGS. 8A to 8C further includes another reflecting mirror in addition to the structure described with reference to FIG. That is, the photographing device 50 shown in FIG. 1 captures a person image of the subject person 100 reflected by the reflecting surface of the reflecting mirror 6 with the photographing camera 1, and inverts image data of the photographed person image in the control unit 7. The processing unit 2 forms a regular human image by inverting the human image left and right to form a mirror image.

On the other hand, in the photographing device 50 shown in FIGS. 8A to 8C, in addition to the rotatable reflecting mirror driven by the reflecting mirror swing mechanism 5, it is separately fixed. A reflecting mirror is provided, and a person image of the subject person 100 reflected by the reflecting surface of the separate reflecting mirror is photographed by the photographing camera 1, and image data of the photographed person image is processed by the control unit 7.

That is, the photographing device 50 shown in FIG. 8A has a fixed first reflecting mirror 21 and a rotatable second reflecting mirror 21.
The photographing camera 1 includes a second reflecting mirror 20.
Of the subject person 100 reflected on the reflecting surface of the subject.

At this time, the human image reflected by the reflecting surface of the first reflecting mirror 21 is an erect mirror image in which the left and right of the subject person 100 are inverted. The human image reflected on the reflecting surface of the second reflecting mirror 20 is an inverted mirror image of the erect image reflected on the reflecting surface of the first reflecting mirror 21. That is, the inverted mirror image reflected by the reflecting surface of the second reflecting mirror 20 is a regular human image of the subject person 100.

Since the photographing camera 1 photographs the inverted mirror image reflected on the reflecting surface of the second reflecting mirror 20, the control unit 7 does not need to invert the image data of the human image.

The photographing device 50 shown in FIG. 8B has a fixed first reflecting mirror 21 and a rotatable second reflecting mirror 20.
And

At this time, the human image reflected on the reflecting surface of the first reflecting mirror 21 is an upright mirror image in which the subject person 100 is inverted left and right. The human image reflected on the reflecting surface of the second reflecting mirror 20 is an erect mirror image of the image reflected on the reflecting surface of the first reflecting mirror 21. That is, the erecting mirror image reflected by the reflecting surface of the second reflecting mirror 20 is a normal human image of the subject person 100.

Since the photographing camera 1 photographs the erect mirror image reflected by the reflecting surface of the second reflecting mirror 20, it is not necessary for the control section 7 to invert the image data of the human image.

In the photographing device 50 shown in FIGS. 8A and 8B, as described above, the first reflecting mirror 21 is fixed.
The second reflecting mirror 20 that reflects the image reflected by the reflecting surface of the first reflecting mirror 21 is configured to be rotatable. For this reason, in order to be able to photograph a subject person having a certain difference in sitting height, the reflecting surface of the first reflecting mirror 21 is made sufficiently large, while the reflecting surface of the second reflecting mirror 20 can be formed compactly. The occupied space for allowing the rotation of the second reflecting mirror 20 can be reduced.

The photographing device 50 shown in FIG. 8C has a rotatable first reflecting mirror 20 and a fixed second reflecting mirror 21.
And

At this time, the human image reflected on the reflecting surface of the first reflecting mirror 20 is an upright mirror image in which the subject person 100 is inverted left and right. The human image reflected on the reflecting surface of the second reflecting mirror 21 is an erect mirror image of the image reflected on the reflecting surface of the first reflecting mirror 20. That is, the erecting mirror image reflected by the reflecting surface of the second reflecting mirror 21 is a normal human image of the subject person 100.

Since the photographing camera 1 photographs the erect mirror image reflected on the reflecting surface of the second reflecting mirror 21, the control unit 7 does not need to invert the image data of the human image.

In the photographing device 50 shown in FIG.
As described above, the first reflecting mirror 20 is made rotatable, and the second reflecting mirror 20 reflects the image reflected on the reflecting surface of the first reflecting mirror 20.
The configuration is such that the reflecting mirror 21 is fixed. Therefore, in order to be able to photograph a subject person with a certain sitting height difference,
The size of the reflecting surface of the rotatable first reflecting mirror 20 can be made compact to some extent.
The occupied space for allowing the rotation of the reflecting mirror 21 can be reduced. In addition, the reflecting surface of the second reflecting mirror 21 can be formed compact.

As described above, according to the photographing apparatus 50 shown in FIGS. 8A to 8C, the control unit 7 inverts the image data of the person image by combining the even number of reflecting mirrors. Since the image inversion processing unit for processing can be omitted, the cost of the control unit 7 can be reduced.

Further, the optical axis connecting the photographing camera 1 and the subject person 100 is bent a plurality of times to form the photographing device 5.
It is possible to reduce the photographing distance between the object 0 and the subject person 100, and it is possible to further reduce the size.

The photographing apparatus 50 shown in FIG. 9 uses a part of the light beam forming the person image of the subject person 100 instead of the reflecting mirror 6 in the structure of the photographing apparatus described with reference to FIG. A beam splitter 22 is provided which reflects the light toward the photographing camera 1 and transmits a part of the light beam to the rear, that is, to the staff 101 side. In FIG. 9, the swing mechanism 5 for driving the beam splitter 22 in the vertical direction is omitted for easy understanding of the configuration.

With this configuration, the attendant 1
No. 01 allows the person image of the subject person 100 to be directly confirmed through the beam splitter 22, and the display unit 8 can be omitted.

As described above, according to the photographing apparatus of the present invention, the reflecting mirror 6 for reflecting the person image of the subject person 100 is used.
A photographing camera 1 for photographing a person image reflected by the reflecting surface of the reflecting mirror 6; and a control unit 7 for processing image data of the person image photographed by the photographing camera 1. In the above, the face position of the person image is detected from the image data, and the reflecting mirror 6 is moved in the vertical direction, that is, the vertical Is pivoted in the vertical direction.

Therefore, since the face position can be adjusted at high speed, the burden on the staff can be reduced and the photographing can be performed efficiently. In addition, since it is possible to photograph a face photograph of sufficient image quality without using the photographing camera 1 having an excessively high resolution, it is possible to prevent an increase in cost and a decrease in resolution. Further, since the optical axis of the photographing camera 1 is bent by the reflecting mirror 6,
It is possible to prevent the device from expanding in the depth direction, and to achieve downsizing.

In the above-described embodiment, a configuration in which only the vertical adjustment of the subject person is automatically performed has been described. However, the horizontal adjustment of the subject person can also be automatically performed. Needless to say.

[0102]

As described above, according to the present invention, it is possible to provide a photographing apparatus capable of reducing the burden on the staff and efficiently performing photographing without increasing the cost and lowering the resolution.
