Remembering the color pixel data, method and its execution expedient, and uses this method the display which drive display

摘要

The method of remembering the color pixel data, per color component offers the pixel data of YUV type of 1st bit number. Decreasing U of each pixel data element, and the bit number of V component it offers the correction YUV data, in every pixel, without referring to the other pixel data it executes the decrease of bit number. You remember the data, with the type which maintains the independence between the respective pixels. This makes that the data inside memory is processed with simple method possible, for example, makes that it changes the individual pixel data possible, simplifies the image processing like revolution and reflected image conversion. Brightness information Y is retained, only kurominansu information is compressed. This, while with the gray scale picture and the text picture making that high quality is maintained possible, it can do also to offer the loss of color resolution in the nature picture where the user cannot perceive.
