IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS

摘要

A page containing a large number of graphics and therefore having a high process load can be processed in parallel and quickly by dividing an edge extraction process into a plurality of threads. In this case, if the number of cores is eight, the edge extraction process is performed by allocating four cores to one of regions obtained by dividing a page and the remaining four cores to the other region.

主权项

1. An image processing apparatus including a multi-core CPU and capable of performing a process using multiple threads, comprising:
an edge extraction unit that performs an edge extraction process as a thread performed by a separate processor core for each object contained in PDL data; a synthesis unit that synthesize edge information extracted from the objects; and a unit that generates raster image data based on the synthesized edge information obtained by the synthesis unit,wherein
the edge extraction unit performs the edge extraction process by allocating a predetermined number of threads to each of regions obtained by dividing one page.
