Image processing device, method, and program
First Claim
1. An image processing device, comprising:
- imaging means that takes an image;
facial image extraction means that extracts a facial image from the image;
masking pattern generation means that generates a masking pattern to mask a part of an image, and repeatedly changes the masking pattern until a state where a facial image other than the facial image of a visitor cannot be extracted from the image by the facial image extraction means; and
recording means that records the masking pattern when the facial image extraction means cannot extract the facial image other than the facial image of a visitor from the image that has been masked using the masking pattern generated by the masking pattern generation means.

Abstract
To prevent detection of facial images for whom detection is unnecessary, without reducing the detection ratio of registered players from facial images. An image acquisition unit acquires an image taken by a camera, and provides the image to a masking process unit. The masking process unit reads a masking pattern that has already been adjusted by a masking pattern adjustment unit and a movable masking area setting unit so that characteristic quantities of a facial image that does not need to be recognized as a facial image cannot be detected, from a masking pattern recording unit. A masking process is applied to the image provided, and the masked image is provided to a facial image extraction unit. The facial image extraction unit extracts a rectangular shaped facial image, and provides the facial image to a transmission unit. The transmission unit transmits the rectangular facial image provided to a face recognition server.

8. An image processing method, comprising:
-
an imaging step of taking an image;
a facial image extraction step of extracting a facial image from the image;
a masking pattern generation step of generating a masking pattern for masking a part of the image, and repeatedly changing the masking pattern until a state where a facial image other than the facial image of a visitor cannot be extracted from the image, by the process in the facial image extraction step; and
a recording step of recording the masking pattern when the facial image extraction means cannot extract a facial image other than the facial image of a visitor from the image that has been masked using the masking pattern generated in the process of the masking pattern generation step.

9. A program executed on a computer, comprising:
-
an imaging step of taking an image;
a facial image extraction step of extracting a facial image from the image;
a masking pattern generation step of generating a masking pattern for masking apart of the image, and repeatedly changing the masking pattern until a state where a facial image other than the facial image of a visitor cannot be extracted from the image by the process in the facial image extraction step; and
a recording step of recording the masking pattern when the facial image extraction means cannot extract a facial image other than the facial image of a visitor from the image that has been masked using the masking pattern generated in the process of the masking pattern generation step.
