BIT-BUDGET MONITOR FOR COMPRESSED IMAGE

PROBLEM TO BE SOLVED: To provide a monitor wherein a video artist can make the video image quality the highest, the bit rate or the file size which are needed can be minimized, and a compressed image signal can be observed. SOLUTION: Compressed image signals are decomposed by a block parser 26 into a plurality of images and blocks of pixels which are shown by a bit sequence in each image. A bit counter 28 counts the bits in each bit sequence and generates the corresponding bit-counted value. A count color transformation apparatus 30 transforms the bit-counted value to the values of color and luminance which show the bit counted value. An indicator monitor 32 indicates the values of color and luminance as indication, in which region mapping was performed on an indicator 24. COPYRIGHT: (C)2006,JPO&NCIPI
