Abstract

An automatic correcting device of an identification photo system comprises a skin pigmentation area abstracting device that abstracts a skin pigmentation area from an image of a person, a skin pigmentation correction value calculating device that calculates skin pigmentation correction values according to colors of the skin pigmentation area abstracted by the skin pigmentation area abstracting device and a predetermined skin pigmentation correction target value, and a color correcting device that corrects colors of the skin pigmentation area according to the skin pigmentation correction values calculated by the skin pigmentation correction value calculating device. Thus, the skin pigmentation of the person in the photo can be corrected to the person'"'"'s true pigmentation.

Claims

1. An identification photo system that obtains image data for an identification photo of a person from image data of the person, said identification photo system comprising an automatic correcting device that automatically corrects the image data of the person.

2. The identification photo system as defined in

claim 1

, wherein said automatic correcting device corrects at least one of density, color balance, luminance and saturation of an image of the person.

3. The identification photo system as defined in

claim 1

, wherein said automatic correcting device comprises:

a skin pigmentation area abstracting device that abstracts a skin pigmentation area from the image;

a skin pigmentation correction value calculating device that calculates skin pigmentation correction values according to colors of the skin pigmentation area abstracted by said skin pigmentation area abstracting device and a predetermined skin pigmentation correction target value; and

a color correcting device that corrects the colors of the skin pigmentation area according to the skin pigmentation correction values calculated by said skin pigmentation correction value calculating device.

4. The identification photo system as defined in

claim 3

, wherein said color correcting device corrects colors of all the image according to the skin pigmentation correction values calculated by said skin pigmentation correction value calculating device.

5. The identification photo system as defined in

claim 1

, wherein said automatic correcting device comprises:

an area separating device that separates the image into a person area and a background area; and

a background changing device that changes colors of the background area to a predetermined color.

6. The identification photo system as defined in

claim 5

, wherein said automatic correcting device further comprises:

a comparing device that compares the size of the person area of the person image with a predetermined size;

an image size changing device that changes the size of the image so that the size of the person area is the predetermined size; and

an abstracting device that abstracts a print area required for the identification photo from the image according to the size of the image.

7. The identification photo system as defined in

claim 1

, wherein said automatic correcting device comprises:

a cloth area abstracting device that abstracts a cloth area from the image; and

a cloth changing device that changes image data of the cloth area to image data of predetermined cloth.

8. The identification photo system as defined in

claim 1

, further comprising a printer that prints the identification photo from the image data for the identification photo.

9. An image processing method in which image data for an identification photo of a person is obtained from image data of the person, said image processing method comprising the steps of:

abstracting a skin pigmentation area from an image of the person;

calculating skin pigmentation correction values according to colors of the abstracted skin pigmentation area and a predetermined skin pigmentation correction target value; and

correcting the colors of the skin pigmentation area according to the calculated skin pigmentation correction values.
