摘要
In the image drawing apparatus, a drawing position last time is stored in advance in a drawing position memory section, and a linear complementing processing section specifies pixels to be complemented from the last drawing position stored in the drawing position memory section and a drawing this time, and calculates semi-transparent rates of the pixels specified. A semi-transparency processing section then calculates pixel values of the pixels to be complemented by using the calculated semi-transparent rates. Therefore, anti-aliasing processing can be carried out at a high speed.
