<p><P>PROBLEM TO BE SOLVED: To provide an image signal decoding device enabling to visually recognize coded information on a decoded image while the device is mainly used for analysis of the coded image signal. <P>SOLUTION: A coded information converting section 8 selects coded information per macroblock from information subjected to variable length decoding in a variable length decoding section 3, and generates a color difference signal on the basis of the information. When an instruction of outputting a decoded image is given on the basis of a selecting signal 10 to be inputted from the outside, a color difference signal selecting section 9 selects and outputs a color difference signal of the decoded image stored in a frame memory 6. When an instruction of outputting coded information is given on the basis of a selecting signal 10 to be inputted from the outside, the color difference signal selecting section 9 selects and outputs a color difference signal generated in the coded information converting section 8. An image signal output section 11 outputs an image signal 12 consisting of a luminance signal of the decoded image stored in the frame memory 6 and the color difference signal selected in the color difference signal selecting section 9. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
