Abstract
An image motion detection device includes: a first motion detection section for generating a first motion vector by performing a first motion vector search for a first block included in an image; a search information calculation section for calculating search information by using the first motion vector; a second motion detection section for generating a second motion vector by performing a second motion vector search for a second block included in the image based on the search information, the first block being different from the second block, and the first motion vector search being different from the second motion vector search; and a motion vector selection section for selectively outputting either the first motion vector or the second motion vector. The number of candidates for the second motion vector in the second motion vector search is smaller than the number of candidates for the first motion vector in the first motion vector search.
