2. Description of the Related Art In recent years, an ID card (Identification Card) has come to be used to prove oneself. Since an ID card is a card for certifying oneself, for example, an identification number (ID number) of oneself is printed on the surface of the ID card, a photograph of a face is printed, and the name, date of birth, address, expiration date, etc. Are described. Examples of this type of card include a license, a company employee ID card, a credit card, and a passport.

In order to create an ID card, a photograph of the face attached to the application form is photographed by the photographing apparatus (copy photographing).
There is a need to. In this case, when the face photo is attached to the application form, the face photo may be attached at an angle, or the face photo may be inclined because the application itself is inclined.

FIG. 5 is a diagram showing the state of the application form.
(A) shows a normal state, (b) and (c) show an abnormal state. In the figure, 10 is an application form, 1 is a facial photograph, 2
Is an ID number. In the application form 10, the name, the date of birth, the address, etc. are described in addition to the face photograph and the ID number, but they are omitted here. (B) shows a state where the face photograph is attached obliquely, and (c) shows a state where the face photograph is inclined because the application form 10 itself is inclined.

In the normal photographing shown in (a), the face photograph 1 is photographed by the camera of the copying photographing apparatus,
Number 2 is OCR (Optical Character Reader)
Read in. In this way, when the face photograph and ID number are read, they are sent to the ID card printer and printed on a blank card (raw ID card) along with the ID information (personal information) sent separately. Done, I
A D card is created.

On the other hand, in the case of taking the obliquely photographed face shown in (b) and (c), the camera is directly photographed and the obliquely photographed face is corrected by image processing. There is.

Further, the arrangement of the cameras is determined in advance so that the distance between the camera for taking a face photograph and the subject (face photograph) is a distance that matches the photograph size.

[0008]

When a photograph of an obliquely inclined face is taken by a camera, image processing for correcting the inclination is performed on the photographed facial photograph image as described above. There is. However, this method corrects the obliquely photographed face photograph image by image processing and forcibly rotates the image, so that there is a problem that the image quality deteriorates. In addition, when the face photograph is pasted diagonally, there is also a problem that all the face images are not photographed because it exceeds the photographing range of the camera.

The present invention has been made in view of the above problems, and does not deteriorate the image quality even when the face photograph attached to the application form is oblique to the camera. The purpose is to provide an application photography device.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a face photograph as a subject. The facial photograph 1 is attached to the application form 10 (not shown). Reference numeral 20 is a camera for taking the facial photograph 1, and 21 is a camera control unit for moving and / or rotating and / or zooming up / down the camera 20. A video camera, for example, is used as the camera 20, and the captured image is obtained as a digital image. The camera 20 is of a type in which the face image is always output as an image signal when facing the face photograph 1.

The camera control unit 21 has a moving mechanism, a rotating mechanism, and a zoom mechanism for the camera 20, and moves, rotates, and zooms up / down the camera 20. The moving mechanism, the rotating mechanism, and the zoom mechanism do not necessarily have to be provided, and at least one function of these mechanisms, particularly the rotating function, may be provided.

Reference numeral 22 is an image inclination detecting means for detecting the inclination of the face photograph 1. As the image inclination detecting means 22, one having an existing technique for detecting the inclination of a face photograph is used. For example, the one that detects the inclination of the image by detecting the edge of the photograph based on the image captured by the camera 20 is used.

Reference numeral 23 is a control device for controlling the overall operation, and for example, a CPU is used. 24 is a control device 23
Is an operation unit that is connected to and inputs various commands and the like. As the operation unit 24, for example, a keyboard or a mouse is used. Reference numeral 25 is a memory for storing various types of data, and 26 is a display unit for displaying various types of information. For example, a RAM is used as the memory 25, and a CRT or a liquid crystal display is used as the display unit 26. The operation of the apparatus thus configured will be described below.

First, the application form 10 (see FIG. 5) is set at a predetermined position. In this case, it is desirable to provide a frame so that the application form 10 does not tilt and set the application form in the frame. In this case, the camera 20
Is set in advance so that the photographing center is near the center of the facial photograph 1 of the application form 10. The control device 23 operates the zoom mechanism of the camera control unit 21 to zoom down,
Make sure that the entire face picture 1 is in the field of view. In this case, it is conceivable that the image taken by the camera 20 is image-processed and feedback control is performed on the zoom mechanism so that the entire photographic image is in the field of view, but no matter how the facial photograph is attached. It is easier to control in advance by previously obtaining a zoom-down position such that the whole is in the field of view and driving the camera control unit 21 so that the control device 23 is always at the fixed position. In this way, when the camera 20 takes the face photograph 1, a part of the face image is not lost.

When the control device 23 confirms that the whole face photograph 1 has entered the field of view, it drives the camera control section 21 to operate the moving mechanism to move the photographing center of the camera to the center of the face photograph. . The center of the face photograph 1 can be obtained by performing image processing on the control device 23 based on the image data captured by the camera 20. FIG. 2 is an explanatory diagram of the movement of the camera. In the figure, A is the center of the facial photograph 1,
B is the shooting center of the camera 20. In the figure, the photographing center B of the camera is moved to the center A of the face photograph. In this way, the image does not fly out of the field of view even when the camera is rotated for tilt correction.

When the photographing center of the camera 20 is moved to the center of the face photograph 1, the control device 23 then rotates the camera 20 so that the inclination detected by the image inclination detecting means 22 becomes zero. In this case, since the photographing center of the camera is located at the center of the facial photograph 1, there is no possibility that a part of the image will be skipped due to rotation. Also,
According to this method, the image quality is not deteriorated because the inclination is not corrected by the image processing.

FIG. 3 is an explanatory diagram of rotation correction. (A) shows a state before correction, and (b) shows a corrected state. An image tilted by θ with respect to the horizontal line L has a tilt of 0 as shown in (b). This is a result of tilting (rotating) the camera 20 itself by θ with respect to the tilt θ so that the face photograph 1 can be seen in the same phase. FIG. 4 is a diagram showing the positional relationship between the face photograph and the camera when the tilt is corrected.
When the face photograph 1 is inclined by θ with respect to the horizontal line L1, the camera 20 is also rotated by θ with respect to the horizontal line L2. In this way, since the inclination of the face photograph 1 and the inclination of the camera 20 are set to the same angle, the inclination of the face photograph taken by the camera 20 is corrected as shown in FIG. 3B. In this way, it is possible to take an image without tilting the image with respect to the camera.

When the tilt correction is completed in this way, the control device 23 operates the zoom mechanism of the camera control unit 21 to adjust the zoom of the camera 20 as necessary and take a face picture. By doing so, it is possible to obtain an optimum image size when an ID card is created.

In the series of sequences described above, the control unit 23 causes the display unit 26 to display the facial photograph image taken by the camera 20, and then the corrected facial photograph is displayed on the display unit 26.
Can be displayed. The operator
The captured image can be monitored as needed.

In the above-described embodiment, the case where the tilt correction is performed after the photographing center of the camera is moved to the center of the face photograph after the entire subject photograph is in the field of view has been described. However, the present invention is not limited to this. For example, after the entire subject photograph is within the field of view, rotation correction may be performed next, and then the photographing center of the camera may be moved to the center of the face photograph.
