ABSTRACT:
An image storage device which stores portions of image data defining pixels making up an image (e.g., a very large image) for further processing, and an image processing device including the image storage device. The image storage device includes an addressing unit for sequentially receiving the image data defining the pixels making up the image, and addressing the pixels as a grid of multi-pixel cells; a working memory for storing only the image data defining those pixels included in certain of the cells; storage units for storing information concerning those cells; and a storage control unit for specifying, as the image data defining the pixels making up the image is being received by the image storage device, those pixels whose image data is to be stored in working memory. The working memory stores the image data for those pixels included in cells having particular image characteristics, and, possibly, the image data for those pixels included in the cells neighboring those cells. The image storage device stores less than all of the image data pertaining to all of the pixels of the image.
