Abstract
A polygon filling control apparatus including an image memory unit divided into a plurality of block memories and a plurality of linear interpolation operation units (DDAs) for generating filling pixel data for different line segments. Output data supplied from side interpolation circuits are selectively supplied to the DDAs concerned and simultaneously linearlly interpolated, and the filling pixel data generated by the different DDAs are simultaneously written into the image memory unit.
