Title:
IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2010/064675
Kind Code:
A1
Abstract:
An image processing apparatus, image processing method and program wherein the quality of inter-prediction images can be improved even when a motion compensation of integer precision is performed. An arithmetic unit (115) adds a transform coefficient as inverse-orthogonal-transformed and supplied by an inverse orthogonal transform unit (114) to an inter-prediction image supplied by a switch (214) for decoding. A motion predicting/compensating unit (212) motion-compensates the decoded image. A FIR filter (213) filters the image as motion-compensated, using a filter coefficient that is transmitted by an image encoding apparatus in correspondence to a compressed image and that has been obtained by using a least squares method when the compressed image was generated. The FIR filter (213) then supplies, as an inter-prediction image, the image as filtered to the switch (214). This invention is applicable to, for example, an image decoding apparatus that performs decoding by use of H.264/AVC system.
