動きベクトル検出装置、撮像装置、動きベクトル検出方法、及びプログラム
Document Type and Number:
Japanese Patent JP7324065
Kind Code:
B2
Abstract:
A detection unit successively selects each of a plurality of blocks of a target image as a target block and detects a motion vector of the target block using a reference image. During motion vector detection, a control unit performs control to partially store the reference image into a storage unit so as to achieve a state where a search range for the target block is stored. The detection unit selects each of the plurality of blocks as the target block in an order of raster scan for each of N regions obtained by dividing the target image in a horizontal direction. When a temporal distance between the target image and the reference image is a second distance that is longer than a first distance, a value of N is large compared to a case where the temporal distance is the first distance.
