Patent Number: 8,818,121

Title: Motion detector, image processing device, and image processing system

Abstract: 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.
