Image attribute discrimination apparatus, attribute discrimination support apparatus, image attribute discrimination method, attribute discrimination support apparatus controlling method, and control program

An image attribute discrimination method for discriminating an attribute of image data based on a content produced by the image data, the image attribute discrimination method comprising the steps of:

• specifying 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 further comprises a heterogeneous matter whose attribute is different from that of the content originally produced by the image;
• discriminating 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 excluding data of the heterogeneous region from the remaining of the image data, if the image data contains the heterogeneous region;
• and
• restoring 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,
• wherein the image data is stored in a data storage hardware logic and the content produced by the image data is displayed by a display device,
• wherein the attribute is a characteristic of a scene shown by the image data, and
• wherein the image attribute discrimination method further comprises determining whether each pixel in the specified heterogeneous region is the target pixel whose feature quantity is extracted in the discriminating, wherein the discriminating 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, the out-of-target pixel is determined to be out of the target in the determining.

A non-transitory computer readable medium comprising a control program that causes a computer to perform steps of:

• specifying 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 further comprises a heterogeneous matter whose attribute is different from that of the content originally produced by the image;
• discriminating 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 excluding data of the heterogeneous region from the remaining of the image data, if the image data contains the heterogeneous region;
• and
• restoring 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 re ion does not become a feature quantity extracting target,
• wherein the image data is stored in a data storage hardware logic and the content produced by the image data is displayed by a display device,
• wherein the attribute is a characteristic of a scene shown by the image data, and
• wherein the control program causes the computer to further perform determining whether each pixel in the specified heterogeneous region is the target pixel whose feature quantity is extracted in the discriminating, wherein the discriminating 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 in the determining.
