Abstract: To provide an image processing apparatus and method that enable high speed and high quality image drawing process. When a drawing instruction including drawing logical arithmetic process instruction is input to a drawing instruction converting unit, the drawing instruction converting mans converts the input drawing instruction to a drawing object and a drawing logical arithmetic process instruction and then stores these to a drawing object storing unit. A drawing logical arithmetic process instruction determining unit determines whether the drawing logical arithmetic process instruction has content to be drawn without logical arithmetic process or not. As a result of determination, when the drawing logical arithmetic process instruction is determined to have content to be processed without drawing logical arithmetic process, the drawing object converting unit converts the determined drawing logical arithmetic process instruction and drawing object to the instruction and drawing object which do not require the drawing logical arithmetic process and transfers the subsequent processes to the other processing unit.
