Abstract:
When processing image data by referring to at least one of reference image data and correction data, an image is processed in a unit of band area by dividing image data of a target image in a plurality of band areas. In this case, the minimum transfer unit of the image data is set. The minimum transfer unit of at least one of the reference image data and the correction data is obtained to process the image data in the minimum transfer unit. The transfer rate of the image data is determined so that the image data to be buffered fits in a capacity of a buffer available in image processing. The height of the band area to be created by division is determined based on the ratio of the transfer rate of the image data to the minimum transfer unit of the image data.
