Title:
動きベクトル検出装置、動きベクトル検出方法及びプログラム
Document Type and Number:
Japanese Patent JP4748191
Kind Code:
B2
Abstract:
A motion vector detecting apparatus includes an evaluation value information forming unit to form evaluation value information of motion vectors evaluating a possibility that a reference pixel is a candidate motion of a target pixel on the basis of pixel value correlation information between the target pixel in one of frames on a time axis in moving image data and the reference pixel in a search area in another of the frames, perform counting on at least one of the target pixel and reference pixel when a strong correlation is determined on the basis of the pixel value correlation information, and determine an evaluation value to be added to the evaluation value information on the basis of a count value obtained through the counting; a motion vector extracting unit to extract candidate motion vectors; and a motion vector determining unit to determine a motion vector among the candidate motion vectors.
