Patent ID: 8922836

Claim:
An image processing apparatus comprising: a receiving unit configured to receive a sequence of a plurality of rendering commands for rendering a plurality of objects, wherein the plurality of the rendering commands include two rendering commands for rendering objects of the plurality of objects by XOR rendering logics and a rendering command, between the two rendering commands, for rendering one object of the plurality of objects by AND rendering logic; a determination unit configured to determine whether a distribution pattern of both on-pixels and off-pixels included in the one object to be rendered by the AND rendering logic has regularity; and a conversion unit configured to convert the plurality of objects into a single transparent object having a transparency parameter which is determined on the basis of the distribution pattern, if the determination unit determines that the distribution pattern has regularity, and not to convert the plurality of objects into a single transparent object having a transparency parameter, if the determination unit determines that the distribution pattern does not have regularity.
