Method of processing image data and apparatus operable to execute the same

Abstract

It is received image data obtained by capturing an image. The image data is compared with a prescribed criterion for judging whether the image includes a prescribed part of a human, and it is extracted a part of the image that is asserted as a part including the prescribed part of the human with a matching degree with respect to the criterion. The extracted part of the image is corrected in accordance with the matching degree to obtain corrected image data.

Claims

1. A method of processing image data, comprising: receiving image data obtained by capturing an image;comparing the image data with a prescribed criterion for judging whether the image includes a prescribed part of a human, and extracting a part of the image that is asserted as a part including the prescribed part of the human with a matching degree with respect to the criterion; andcorrecting the extracted part of the image in accordance with the matching degree to obtain corrected image data.

2. The method as set forth in claim 1, wherein: the extracted part of the image is corrected with a correction amount corresponding to the matching degree.

3. The method as set forth in claim 1, wherein: the extracted part of the image includes a plurality of parameters adapted to be corrected; andthe number of parameters to be corrected is varied in accordance with the matching degree.

4. The method as set forth in claim 1, wherein: the prescribed part of the human is a face.

5. The method as set forth in claim 3, wherein: the parameters includes brightness and hue.

6. The method as set forth in claim 5, wherein: the image data is defined by a first color space; andthe correcting includes converting the image data into converted data defined by a second, colorimetric color space and adapted to be the corrected image data.

7. The method as set forth in claim 1, wherein: the correcting is performed in a case where the matching degree is no less than a prescribed value.

8. The method as set forth in claim 1, further comprising: generating an image based on the corrected image data.

9. An apparatus operable to process image data, comprising: a receiver, operable to receive image data obtained by capturing an image;an analyzer, operable to compare the image data with a prescribed criterion for judging whether the image includes a prescribed part of a human, and to extract a part of the image that is asserted as a part including the prescribed part of the human with a matching degree with respect to the criterion; anda corrector, operable to correct the extracted part of the image in accordance with the matching degree to obtain corrected image data.

10. The apparatus as set forth in claim 9, further comprising: an image generator, operable to generate an image based on the corrected image data.
