Abstract:
1. An image attribute discrimination apparatus that discriminates an attribute of image data based on a content produced by the image data, the image attribute discrimination apparatus comprising: a heterogeneous region specifying hardware logic that specifies a character region including a character as a heterogeneous region from the image data of a still image based on a determination whether the image data of the still image contains the heterogeneous region, wherein the heterogeneous region comprises a heterogeneous matter whose attribute is different from that of the content originally produced by the image data; an attribute discrimination hardware logic that, if the image data contains the heterogeneous region, discriminates the attribute of the image data based on a feature quantity extracted from a pixel group except each pixel in the heterogeneous region in each pixel of the image data and excludes data of the heterogeneous region from the remaining of the image data, wherein the attribute is a characteristic of a scene shown by the image data; a restoration hardware logic that restores a pixel identical to a target pixel with respect to an out-of-target pixel region in each pixel of the image data, wherein the out-of-target region does not become a feature quantity extracting target; and a target pixel determination hardware logic that determines whether each pixel in the heterogeneous region specified by the heterogeneous region specifying hardware logic is the target pixel whose feature quantity is extracted by the attribute discrimination hardware logic, wherein the attribute discrimination hardware logic discriminates the attribute of the image data based on the feature quantity extracted from the pixel group except the out-of-target pixel in each pixel of the image data, and the out-of-target pixel is determined to be out of the target by the target pixel determination hardware logic.
