Title:
MOTION DETECTION APPARATUS, MOS (METAL-OXIDE SEMICONDUCTOR) INTEGRATED CIRCUIT AND VIDEO SYSTEM
Document Type and Number:
Japanese Patent JP2008136177
Kind Code:
A
Abstract:
To solve such a problem that when a motion search range is preset and the movement of an image is violent, the image may be present out of the motion search range.
A motion detection apparatus 11 is equipped with a target image memory 3, a reference image memory 4, a reference image memory control section 6 and a motion detection section 8. When the motion detection section 8 detects a motion vector for an image of a first target macro block, the reference image memory control section 6 determines the motion search range using surrounding motion vectors that are motion vectors detected for images of target macro blocks present around the first target macro block.
