Abstract:
1. An image drawing apparatus in communication with a host and for conducting a data transfer at a bit unit for image data stored in a memory device, comprising: a region storing part storing based upon a single coordinate instruction from the host, coordinate information of a single inside region of the image data where at least one attribute value concerning a pixel is not constant in the image data; an attribute value storing part storing each attribute value of pixels in the single inside region; a constant value storing part storing a constant value as the attribute value; an inside region determining part determining whether a coordinate being transferred is within the single inside region; a selection signal generating part generating a selection signal selecting reading an attribute value from the attribute value storing part and/or from the constant value storing part, based on the determining of whether the coordinate is within the single inside region; and reading the attribute value from the selected storing part for processing the source image data, wherein the inside region determining part further comprises:
