When the input image a is an image of the non-YUV 420 format and the coding unit is the minimum CU block, the adaptive thinned-out luminance reference pixel acquiring unit (21 A) acquires the reference pixels around the luminance block corresponding to the color difference prediction target ...

Digital cameras owners venturing into "raw shooting" to get the most of their equipment will find the FastPictureViewer Codec Pack a must have essential tool, as it makes raw file handling in Windows Explorer as simple and easy as it is with the JPEG format: quick identification of images ...

In general, video encoder 200 and video decoder 300 may code video data represented in a YUV (e.g., Y, Cb, Cr) format. That is, rather than coding red, green, and blue (RGB) data for samples of a picture, video encoder 200 and video decoder 300 may code luminance and chrominance...
