Abstract:
1. An image-capturing apparatus which corrects blurring that occurs in an image-captured picture, said image-capturing apparatus comprising: an image-capturing unit configured to image-capture pictures in video form; a blur detecting unit configured to detect occurrence of blurring in an image-captured picture that is image-captured by said image-capturing unit, and a temporal position at which the blurring has occurred; a blur synthesizing unit configured to generate blur-synthesized pictures by using blur-free image-captured pictures and a blurred image-captured picture, and synthesizing artificial blurring onto the blur-free image-captured pictures, the blur-free image-captured pictures being image-captured pictures in which the blurring is not detected by said blur detecting unit, and the blurred image-captured picture being a picture in which the blurring is detected; a picture feature amount transforming unit configured to transform each of the blur-free image-captured pictures, the blur-synthesized pictures, and the blurred image-captured picture into a picture feature amount; and a blur correcting unit configured to correct the blurring in the blurred image-captured picture by identifying a blur-synthesized picture having a picture feature amount that is most similar to the picture feature amount of the blurred image-captured picture and replacing the picture feature amount of the blurred image-captured picture with the picture feature amount of a blur-free image-captured picture corresponding temporally to the identified blur-synthesized picture, the identifying and replacing being performed for each of pixels or blocks in the temporal position at which the blurring is detected by said blur detecting unit, wherein the picture feature amount is a characteristic value reflecting a difference in a brightness value of a target pixel and its surrounding pixels.
