| 摘要 |
<p>The present invention relates to an image processing device, an image processing method, and a program with which it is possible to reduce the amount of processing and the amount of delay while inhibiting deterioration in inter prediction accuracy in cases of performing motion compensation processing with fractional accuracy at the time of inter prediction. If the horizontal and vertical positions, on a reference image, of pixels of a prediction image in inter prediction are at fractional-pixel positions other than half-pixel positions, a reference-image reading unit (41) reads out predetermined reference pixels including reference pixels lined up in two orthogonal oblique directions. Using the predetermined reference pixels that have been read out, an FIR filter (42) computes the pixels at fractional positions in the reference image as the pixels of the prediction image. The present invention is applicable, for example, to encoding devices that perform compression encoding according to the H.264/AVC scheme.</p> |
