Abstract
A buffer memory control device has a plurality of generating units which generate image data of differing formats one line at a time. A storage unit temporarily stores at least one line of image data generated by one of the generating units. A plurality of processing units perform differing image processing of at least one line of image data read from the storage unit. A control unit controls the number of lines of image data to be temporarily stored in the storage unit and the amount of data per line, based on the generating unit which generates the image data stored in the storage unit and the processing unit which performs image processing of the image data read from the storage unit.
