Abstract
A frame image is input. First to Nth intermediate images are generated from the frame image. First to Nth sub-filters that have been generated by dividing an original filter are held, along with relative position information of pixels referred to by each of the sub-filters. Pixel values are collected of pixels in an ith intermediate range (1≦i≦N). N sub-frame images are created by obtaining a pixel value of a pixel of interest in an ith sub-frame image from a calculation value obtained using the ith sub-filter with respect to the collected pixel values.
