Abstract
In executing image processing using low-frequency band evaluation values and high-frequency band evaluation values obtained from an input image, one of a plurality of processors applies the image processing to a partial image assigned thereto using high-frequency band evaluation values obtained from the partial image and low-frequency band evaluation values. This processor distributes, to another processor, low-frequency band evaluation values or a reduced image of the input image to be used by another processor. Another processor applies the image processing to a partial image assigned thereto using high-frequency band evaluation values obtained from the partial image and one selected from the group consisting of the distributed low-frequency band evaluation values and low-frequency band evaluation values obtained from the reduced image, and returns a resultant image.
