Image processing method based on partitioning of image data, image processing device based on partitioning image data and program

摘要

The present invention relates to an image processing method, image processing device and program which make it possible to shorten the processing time, and which also make it possible to set tile regions in appropriate ranges, by dividing one image into a plurality of regions and performing a transformation for each of these regions. The post-transformation image is divided into a plurality of tile regions, and transformation processing and the like are successively performed, with each of these tile regions as the object. In cases where a given tile region that is the object of processing contains a central axis that passes through the origin of the post-transformation image, the tile size of this region is altered by the tile size determining part 41 so that this region does not contain a central axis. The regions on the pre-transformation image corresponding to the tile regions that are the object of processing are calculated by the image region calculating part, and the pixel data contained in the calculated regions is read out from the storage part 18. The present invention can be used in personal computers or the like that process image data acquired by means of a digital camera.
