TLDR
In this article, a color image processing apparatus and method through which it is possible to realize high-speed encoding processing of image data containing data indicative of blank spaces is presented, where a CPU sets data, which is added on as a blank space or margin, in a blank-value setting memory, and a DSP for encoding processing reads in the set value before the start of encoding processing, effects a transformation of the color space to undergo encoding processing and stores the resulting data in its own internal memory, whereby the data stored in the internal memory is used in encoding of blank areas
Abstract
A color image processing apparatus and method through which it is possible to realize high-speed encoding processing of image data containing data indicative of blank spaces. When encoding processing is executed, a CPU sets data, which is added on as a blank space or margin, in a blank-value setting memory, and a DSP for encoding processing reads in the set value before the start of encoding processing, effects a transformation of the color space to undergo encoding processing, and stores the resulting data in its own internal memory, whereby the data stored in the internal memory is used in encoding of blank areas to make possible high-speed encoding processing.
