Motion detector, image processing device, and image processing system

摘要

According to one embodiment, a motion vector detection device includes a reference image encoder, a cutoff module, a reference image decoder, and a block matching module. The reference image encoder is configured to generate a plurality of encoded components. The cutoff module is configured to select, according to a predetermined priority, one or a plurality of encoded components so that a data length is equal to or less than a predetermined fixed length. The reference image decoder is configured to decode the selected one or the plurality of encoded components to reproduce one or a plurality of image components. The block matching module is configured to detect, based on a motion-detection target block in an input image and the reproduced one or the plurality of image components of a matching-target block of the reference image corresponding to the motion-detection target block, a motion vector of the motion-detection target block.

1. A motion vector detection device comprising:
a reference image encoder configured to entropy-encode each of a plurality of image components extracted from a reference image, to generate a plurality of encoded components; a cutoff module configured to select, according to a predetermined priority, one or a plurality of encoded components so that a data length is equal to or less than a predetermined fixed length; a reference image decoder configured to decode the selected one or the plurality of encoded components to reproduce one or a plurality of image components; and a block matching module configured to detect, based on image contents of a motion-detection target block in an input image and the reproduced image components of a matching-target block of the reference image corresponding to the motion-detection target block, a motion vector of the motion-detection target block.
