Image processing apparatus performing pixel similarity judgment and image processing program

摘要

An image processing device according to the present invention includes a similarity factor calculating portion locally comparing pixels that compose an image so as to calculate a similarity factor of the pixels in a predetermined direction, and includes an analyzing portion analyzing the structure of the image in accordance with the similarity factor calculated by the similarity factor calculating portion. In particular, the similarity factor calculating portion selects and changes pixels to be compared in accordance with color shift of the image to calculate the similarity factor. As a result, a similarity factor can be calculated with suppressing influence of color shift.
