To provide a rendering processing method using multiprocessing.

A rendering processing method using multiprocessing includes the steps of: using a pre-rendering management unit to divide an application execution window into frames and to generate a rendering processing instruction for rendering an image for each frame; using a rendering management unit to generate a rendering image for each frame in accordance with the generated rendering processing instruction; and using a memory unit to store the generated rendering image. A procedure for executing the step of generating the rendering processing instruction is divided into at least one procedure, and a procedure for executing the step of generating the rendering image is divided into at least one procedure. The divided procedures can be processed simultaneously by multiple threads.
