DIGITAL IMAGE PROCESSING DEVICE

摘要

PURPOSE: A digital image processing device is provided to enable a repeated rendering process to be escaped by each rendering processor detecting whether a rendered output is constant between adjacent outputs. CONSTITUTION: The digital processing device comprises a plurality of rendering processors arranged at a directed acyclic graph. Each of the rendering processors operates to render an output result associated with another image which is received from a rendering processor of a previous stage in a directed acyclic graph and/or an image from an input data associated with a video signal. The rendering processor detecting whether a rendered output is constant between adjacent outputs, and operates to acquaint the detection result to other rendering processors.
