Abstract: A motion vector detection device of the present invention includes: a parameter setting section having parameters relating to N (N is a natural number equal to or greater than 2) search regions obtained by dividing at least a portion of an entire search region in a search frame; a motion vector detection section for calculating an evaluation value which indicates a degree of correlation between an encoded object block in an object frame and a candidate block in one of the N search regions and for calculating a motion vector based on the evaluation value; a result storage section for storing the motion vector and the evaluation value calculated by the motion vector detection section; and a control section for controlling the motion vector detection section to calculate motion vectors and evaluation values for M (1≦M≦N) different ones of the N search regions until a predetermined condition is satisfied, for receiving the motion vectors and the evaluation values from the result storage section, and for det

Abstract: In order to realize a picture compression processing with a higher efficiency than ever in motion vector detection for motion picture compression coding, an improvement is provided to motion vector selection process when a plurality of candidate blocks having evaluation values of the same correlation degree have been detected from a search area. When there are a plurality of candidate blocks within the search area which have the highest correlation degree with the coding block, a difference is calculated between each of a plurality of motion vectors corresponding to the plurality of candidate blocks, respectively, and the best motion vector which is variable-coded immediately before the best motion vector which is being determined. Based on the calculated difference, the best motion vector is selected from among the plurality of motion vectors.

Abstract: The present invention provides an image coding apparatus and its motion vector detection method, which can reduce a system cost also when the throughput of image data is increased. The image coding apparatus of the present invention comprises a search range frame memory 40 for outputting a search range for motion vector detection, a coding target frame memory 50 for outputting a coding target block, and a motion compensation unit 210 for performing motion compensation by using the coding target block which is input from the coding target frame memory 50 via a second data bus and the search range for the motion vector detection, which is input from the search range frame memory 40 via a first data bus, and obtaining a candidate block having a highest correlation with the coding target block in the search range.
