摘要:
The present invention relates to an image processing apparatus, an image processing method, and a program capable of increasing the quality of a predicted image generated through inter prediction even when a motion compensation process with integer-pel accuracy is performed.A computing unit 115 decodes a transform coefficient subjected to inverse orthogonal transform and supplied from an inverse orthogonal transform unit 114 by adding the transform coefficient to an inter predicted image supplied from a switch 214. A motion prediction/compensation unit 212 performs motion compensation on the decoded image. An FIR filter 213 performs a filter process on the motion-compensated image using a filter coefficient corresponding to a compressed image and transmitted from an image encoding apparatus. The filter coefficient is obtained using the least-square method when the compressed image is generated. The FIR filter 213 supplies the filtered image to the switch 214 as the inter predicted image. The present invention is applicable to an image decoding apparatus that performs decoding using, for example, the H.264/AVC standard.
