ABSTRACT:
In an image drawing apparatus for conducting a data transfer at a bit unit for image data stored in a memory device, a region storing part stores a region where at least one attribute value concerning a pixel is not constant in the image data, an attribute value storing value stores each attribute value of pixels in the region, a constant value storing part stores a constant value as the attribute value, an inside region determining part determines whether or not a coordinate being transferred is within the region, and a selection signal generating part selects one of the attribute value storing part as a selected storing part and the constant value storing part based on a determination result obtained by the inside region determining part, and generating a selection signal indicating the selected storing part, wherein a predetermined process for source image data is conducted by obtaining the attribute value from the selected storing part.
