Abstract:
1. An image processing apparatus including a processor coupled to a memory, comprising: a pixel value calculating unit configured to calculate estimated pixel values of respective pixels of a provisional image composed of “m” pixels by interpolation based on pixel values of respective pixels in a reference frame having “n” pixels (m>n); a segmentation unit configured to segment an interior of the reference frame into (1) an edge region and a texture region, into (2) the edge region and a flat region, into (3) the texture region and the flat region, or into (4) the edge region, the texture region, and the flat region depending on the pixel values of respective pixels in the reference frame; a position calculating unit configured to set the respective pixels in the reference frame as target pixels one by one in sequence and to calculate corresponding positions on the provisional image, of the respective target pixels, in decimal accuracy, which is finer than pixel intervals, based on information on the segmented edge region, texture region, or flat region including the target pixels; a converting unit configured to modify the respective estimated pixel values so that a finite difference from the pixel values of the target pixels to the provisionally estimated pixel values of the target pixels, which are obtained from the estimated pixel values of the provisional image for pixels around the corresponding positions of the target pixels, becomes smaller, and to obtain modified pixel values; and an output unit configured to output an image composed of “m” pixels having the modified pixel values.
