Patent ID: 8150182

Claim:
An image information decoding apparatus including a processor comprising: a motion compensation unit configured to perform, at the processor of the image information decoding apparatus, motion compensation processing of ½ pixel accuracy with respect to an interframe predictive encoding image to generate pixels of ½ accuracy by using a first filter having 8 taps, wherein the motion compensation unit performs motion compensation processing of ¼ pixel accuracy with respect to the interframe predictive encoding image to generate pixels of ¼ accuracy by using a second filter having 8 taps, the motion compensation unit performs motion compensation processing of ½ pixel accuracy with respect to an interframe bi-directional predictive encoding image to generate pixels of ½ accuracy by using a third filter having 6 taps, and the motion compensation unit performs motion compensation processing of ¼ pixel accuracy with respect to the interframe bi-directional predictive encoding image to generate pixels of ¼ accuracy by using a fourth filter having 6 taps.
