DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing apparatus and a photographing method applied to the photographing apparatus, and more particularly to a photographing apparatus and a photographing method 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.

[0004] Therefore, at the time of photographing, it is necessary to perform an adjustment operation for adjusting the face position of the subject person. 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.

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, a person image of a subject person is photographed by a CCD camera or the like in front of a background plate having a constant reflectance, and image data of the photographed person image is generated. This image data is composed of a plurality of line data divided in the vertical direction of the subject person. These line data are composed of a plurality of pixel data arranged in the horizontal direction of the subject person.

At this time, the photographed person image is photographed over an area slightly larger than the size of the frame.
Then, in the photographed image data, the luminance change is searched for one line at a time in order from the upper limit line data to detect the top position of the human image.

That is, the image data corresponding to the background plate has a constant brightness, whereas the image data corresponding to the person has a different brightness from the image data of the background plate. Therefore, from the upper limit line data of the image data,
The pixel data included in the line data is searched for the presence or absence of a luminance change, and the top position of the human image is detected assuming that the position where the luminance change is detected corresponds to the top position of the human image.

[0011] The amount of movement to be adjusted is calculated based on the detected parietal position, and the height is adjusted by moving the photographing camera itself up and down by an electric mechanism or the like.

[0012]

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

That is, in the method of searching for the luminance change in the image data of the photographed person image in order from the line data of the upper limit, it is necessary to extract one line at a time and search for the presence or absence of the luminance change. The time required to detect the position is long, and the shooting time per subject person is long.

Therefore, there arises a problem that the photographing efficiency cannot be improved.

In the method of moving the photographing camera itself in the vertical direction, there is a limit in increasing the speed. 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.

[0016] For this reason, it is difficult to increase the speed, and there arises a problem that the photographing efficiency cannot be improved.

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 a staff member, shorten the time required for photographing, and improve photographing efficiency, and this photographing apparatus.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing 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, the photographing device 50 includes a photographing camera 1 as photographing means, a reflecting mirror 6, a reflecting mirror swing 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.

The image data of the generated human image is composed of a plurality of line data of the subject person 100 divided in the vertical direction. These line data correspond to the subject person 1
00 is composed of a plurality of pixel data arranged in the horizontal direction.

At the time of photographing, the subject person 100
She is sitting on a chair 53, but assuming an upright position,
What is necessary is just to arrange | position the imaging | photography camera 1 in the position according to it.
However, the difference in sitting height is smaller than the difference in height.
That is, it is possible to reduce the adjustment range in the vertical height direction of the human image.

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 person 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, when the reflecting mirror 6 is set to a /
When rotated twice, the optical axis between the reflecting mirror 6 of the photographing camera 1 and the subject person 100 is rotated a degrees. In this embodiment, based on the case where the optical axis of the photographing camera 1 is bent at 90 degrees, if a = ± 4 degrees, that is, if the reflecting mirror can be rotated by ± 2 degrees, the subject person of approximately the height can be obtained. It is possible to correspond to.

On the other hand, when the optical axis of the photographing camera 1 is not bent without the reflecting mirror, to rotate the optical axis between the reflecting mirror 6 of the photographing camera 1 and the subject person 100 by a degree,
It is necessary 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 person, which is automatically adjusted, as will be described later. It is possible.

For example, the reflector swing mechanism 5 includes a frame for holding the reflector 6, a cam follower integrally formed on one end of the frame, and a cam against which a cam follower urged by a spring or the like is pressed. It is configured with such as.
The frame is configured to be rotatable around a fulcrum 6 a on the reflecting surface of the reflecting mirror 6.

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

The reflector swing mechanism 5 may include a piezoelectric element which holds the reflector 6 and rotates the reflector 6 at a fulcrum 6a.

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

Further, the reflector swing mechanism 5 may be provided with a worm wheel for holding the reflector 6, a worm gear attached to the rotating shaft of the motor, and the like. The worm wheel is configured to be rotatable around a fulcrum 6 a on the reflecting surface of the reflecting mirror 6.

When the motor rotates, the worm gear is driven to rotate, and the reflecting mirror 6 held on the worm wheel
It rotates around the fulcrum 6a.

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 image data corresponding to a regular image by inverting the inverted captured 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.

The turning operation of the reflecting mirror 6 is called a tilt operation.

As described above, the feedback loop is formed in the control unit 7. That is, once the vertical adjustment is performed by the tilt operation, the subject person 100 is photographed again by the photographing camera 1, and the image data of the person image is transferred to the face position detection unit 3 via the image inversion processing unit 2. To determine whether the face position is located within a predetermined range of the frame 105. If necessary, the amount of movement of the reflecting mirror is calculated, and the vertical adjustment is performed again by the tilt operation. 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 section 8 displays the subject display image 102 based on the image data of the human image inverted by the image inversion processing section 2. The display unit 8 displays a staff 10
For example, information to be reported to 1 such as error information of the apparatus, operation status, operation information, and the like are displayed.

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 illuminating device 51 includes a subject 10 sitting on a chair 53 in front of a monochrome background plate 52 having a substantially uniform reflectance.
Illuminates 0.

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 amount of movement, and executes a tilt operation of rotating 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 unit 7 again, and the image data is 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 face image of a human image is photographed and captured in a predetermined frame 105 in an ideal state or within a predetermined allowable range.

The image data of the captured face image is sent to the printing machine, and when the attendant 101 presses the print button on the operation panel 9, the captured face image is printed on a predetermined frame of the personal identification medium. , A personal identification medium 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, since the optical axis of the photographing camera is bent by the reflecting mirror, it is possible to prevent the apparatus from expanding in the depth direction, thereby realizing miniaturization.

Next, a method for detecting the face position in the human image of the subject person 100 by the face position detection unit 3 of the control unit 7 will be described more specifically.

As shown in FIG. 2, when capturing image data, a large photographing area 106 is set in advance so that the displacement of the face in the vertical direction and the displacement in the horizontal direction due to variations in the sitting height of the subject person 100 can be adjusted to some extent. Shoot. Thereafter, by the auto-framing process, the position of the face of the human image 102 of the subject person 100, more specifically, the position of the head of the human image 102 is set as a reference from the shooting area 106.
Image area 10 of size corresponding to desired frame size
Cut out 7.

The image data generated when the photographing area 106 is photographed is constituted by a plurality of line data of the person image 102 divided in the vertical direction. The photographing area 106 includes the photographable area 103 having a fixed width of the number L of lines.

The photographable area 103 is the area 1
If the head position of the human image 102 exists in the area 03, it is an area where a predetermined frame is in an ideal state in which an appropriate space can be secured between the frame and the top position of the human image 102. To be more precise, when the human image 102 is not detected on the upper limit line 104 of the photographable area 103 and the human image 102 is detected on the lower limit line 105, it is determined that the state is close to the ideal state in which photographing is possible. , The auto-framing process can be executed.

When photographing the subject person 100 in front of the monochromatic background plate 52 having a substantially constant reflectance, the person image 102 is not detected when the line data included in the image data in the photographing area 106 has a constant luminance. Case, person image 1
02 corresponds to the case where there is no “0” in the data.
Is identified.

Further, the case where the luminance change is detected from the line data included in the image data in the photographing area 106 corresponds to the case where the human image 102 is detected, that is, the case where the human image 102 is present. Identified as "1".

That is, the photographable state corresponds to a state where the line data of the upper limit line 104 is “0” and the line data of the lower limit line 105 is “1” in the photographable area 103.

± 1 from the standard sitting height of the subject person 100
