Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of the image processing apparatus of the present invention. The image processing apparatus according to the present embodiment includes an image input device 1, a computer 2, a printer 3,
An image storage device 4, a display device 5, and an instruction input device 6 are provided.

The image input apparatus 1 reads, for example, an image of a film or a photograph using a CCD, forms a digital image signal indicating the image from the output of the CCD, and outputs the digital image signal to the computer 2. .
Alternatively, the image input device 1 may read out image data recorded on a recording medium such as a magnetic disk or an optical disk and output a digital image signal.

The computer 2 receives and temporarily stores a digital image signal from the image input device 1, performs a process described later on the digital image signal, and displays a face on a predetermined screen at an appropriate size and position. After that, this screen is output to the printer 3 and the image storage device 4.

The printer 3 is a well-known digital printer, which transfers a screen from the computer 2 to a print sheet, develops the print sheet, and discharges the print sheet showing a face in an appropriate size and position on a predetermined screen.

The image storage device 4 may be of any type as long as it is a known digital memory.

The display device 5 displays an image indicated by the digital image signal from the computer 2, that is, an image input through the image input device 1, on a display screen of the display device 5.

The instruction input device 6 is for operating various buttons and moving a cursor displayed on the display screen of the display device 5 and includes various keys and a mouse.

In the image processing apparatus having such a configuration,
According to the flowchart of FIG. 2, the following processing is performed, whereby a human face is printed on a photograph at an appropriate size and position.

First, an image in which, for example, a human face is captured is input to the image input device 1 (step 101). As a result, a digital image signal indicating the image is transmitted from the image input device 1 to the computer 2. Computer 2
Temporarily stores the digital signal, edits the image indicated by the digital image signal into a predetermined dialog (step 102), and outputs a dialog including the image to the display device 5. In response, the display device 5 displays a dialog 11 as shown in FIG. 3 on the display screen (step 103).

In the dialog 11, the image 12 is displayed on the right half thereof, and the rotation button 1
5. Rotation direction arrow 18, and each rotation angle button 19-1 ~
19-5 is displayed. A dotted grid pattern 20 is displayed so as to be superimposed on the image 12. The grid pattern 20 is a reference line indicating a vertical direction and a horizontal direction on the display screen, and is displayed to make it easy to grasp the inclination of the face as described later.

Each type column 13-1, 13-2, for entering the type of print paper in the left half of the dialog 11,
13-3, each number field 14-1, 14-2, 14-3 for entering the number of print sheets, and each type button 16-1, 16-2, 16 for designating the type of print paper -3, and respective color black and white buttons 17-1, 17-2, 17-3 for designating color print or black and white print are displayed.

In this state, first, for example, the rotation button 15 is operated through the instruction input device 6 while observing the face angle of the image 12 on the display screen with reference to the grid pattern 20 on the display screen of the display device 5. And each rotation angle button 19
-1 to 19-5 are selectively operated through the instruction input device 6,
When the user specifies the rotation direction and rotation angle of the image 12 on the dialog 11, the computer 2 responds accordingly.
Performs image processing for rotating the image 12 on the dialog 11 by the rotation angle in the rotation direction (step 1).
04). Thereby, the rotation angle of the image 12 on the dialog 11 is corrected.

Instead of operating the rotation button 15 and the rotation angle buttons 19-1 to 19-5, the instruction input device 6
By clicking on one of the four corners of the image 12 on the display screen by operating the mouse of
In the direction indicated by the rotation direction arrow 18, the image 12
May be rotated to correct the rotation angle of the image 12.

Thereafter, each type button 16-1, 16-2, 1
Any one of 6-3 is designated through the instruction input device 6. For example, when the type button 16-1 is specified, the computer 2 notifies the printer 3 of the size of the print sheet specified by the type button 16-1. In response, the printer 3 selects the designated size of the print paper (step 105).

Next, the user operates the instruction input device 6 to specify the vertex position A of the head of the face and the position B of the chin with respect to the image 12 on the dialog 11, and in response, the computer 2 responds. Then, two positions A and B in the image 12 on the dialog 11 are recognized (step 106).

Further, by operating the instruction input device 6, the type of the ID photograph (eg, for a driver's license, for a passport, for a resume, etc.) is displayed in the type column 13-1 on the dialog 11.
Is entered (step 107), the number of ID photos is entered in the number field 14-1 (step 108), and color or black and white is entered into the color black and white button 17-1 (step 109). At this time, if a plurality of types of ID photos are required (step 110, NO), the other types of columns 13-2,
13-3, other number fields 14-2 and 14-3, and other color monochrome buttons 17-2 and 17-3 are also entered. Here, the entry work in steps 107 to 109 may be a method of selecting from a plurality of keys provided in advance.

The computer 2 is provided for each type of ID photo,
The scale of the face of the image 12 on the dialog 11 and the position of the face are obtained (step 111). That is, assuming that the distance between each of the positions A and B of the designated face is the length of the face, the ratio of the length of the face to the length of the screen of the ID photo is 5: 8. Thus, the scaling ratio of the image 12 is obtained,
Further, when the length of the face is set to 5, the length of the margin above the position A on the screen of the identification photograph (the length of the margin above the head) is 1, and the length below the position B is 1 The position of the face on the screen of the ID photograph is determined so that the height (length under the chin) becomes 2.

The above ratios are basic, but may be changed as required.

When the enlargement / reduction ratio of the image 12 and the position of the face on the screen of the ID photograph are obtained in this manner, the computer 2
Trims the image 12 on the dialog 11 at the scale factor and crops the scaled image so that the face of the scaled image is located at the position on the ID photo screen Thus, an image of the identification photograph is formed at the enlargement / reduction ratio and showing the face positioned at the position (step 112). At the time of this trimming, the portion of the image that has been enlarged or reduced and that protrudes from the ID photo screen is deleted. Further, the computer 2 displays a frame 21 (shown in FIG. 4) indicating a portion of the image to be trimmed on the image 12 on the dialog 11,
Identify the portion of the image to be cropped. When the frame 21 is displayed, the grid pattern 20 is deleted from the display screen.

When the grid pattern 20 and the frame 21 are displayed in different colors, both may be displayed on the display screen.

According to the result of the above operation, the dialog 11
Has a display form as shown in FIG. 4, for example.

Here, the following functions may be further provided. That is, if the ID photo exceeds the original image, there is no image data for the portion outside the frame, so that output (printing) of the ID photo is disabled. Accordingly, entry into the type column on the dialog 11 is also prohibited (for example, change to a blank).
To do.

Next, the computer 2 executes step 105
The printer prints the image of the ID photo showing the scaled and positioned face on the print sheet designated in step S by the number of sheets designated in step 108 in the color or black and white designated in step 109. Instruct 3 In response, the printer 3 prints the ID photo image on the designated print sheet by the designated number of sheets, and discharges the print sheet (step 113). Further, the computer 2 stores the image of the ID photograph in the image storage device 4.

The above steps 111, 112, 113
The process is repeated according to the type of the ID photo designated in step 107. As a result, each type of ID photograph is printed out.

As described above, in this embodiment, when an image in which a human face is captured is input, the inclination of the image and two positions of the face are specified on a dialog, and the type of the ID photo is selected. ,
An ID photograph in which the face is arranged at an appropriate size and position can be obtained. In addition, even if a plurality of types of ID photos are selected at the same time, the face is arranged at an appropriate size and position for each type of ID photo.

The present invention is not limited to the above embodiment, but can be variously modified. For example,
The ratio of the length of the face to the vertical length of the ID photo screen, the length of the margin above the head in the ID photo screen, the length under the chin, etc. can be set as appropriate and can be changed arbitrarily. It does not matter.
Also, any size may be designated as the size of the ID photo. Further, a limit range of the enlargement / reduction ratio of an image in which a human face is captured may be set.

[0040]

As described above, according to the present invention, an image in which a human face is captured is input, the inclination of the image and two positions of the face are designated, and the type of the ID photo is specified. If selected, an ID photograph in which the face is arranged at an appropriate size and position can be obtained. In addition, even if a plurality of types of ID photos are selected at the same time, the face is arranged at an appropriate size and position for each type of ID photo.
