Title:
IMAGE PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2006/009019
Kind Code:
A1
Abstract:
An image processor is provided with a memory part (20) provided with a first memory (21) for storing brightness Y data, a second memory (22) for storing color difference Cb data and a third memory (23) for storing color difference Cr data; and a memory interface part (10) provided with a color information discriminating part (11), a memory control part (12), an address calculating part (13) and a data control part (14). According to color information supplied by a color information control line (40), the memory interface part (10) performs image data address conversion, data processing, etc. at the time of storing/reading image data on a bus (30). As a result, address conversion efficiency at the time of storing the different format image data in the memory and reading it out from the memory can be improved.
