Abstract:
1. A motion vector detection apparatus comprising: an acquisition section which acquires frame data; an activity calculation section which calculates a block activity value based on the frame data acquired by the acquisition section for each of a plurality of correlation detection blocks; an allocation section which allocates the plurality of correlation detection blocks between a first group and a second group based on the block activity value of each of the correlation detection blocks calculated by the activity calculation section; a motion vector calculation section which calculates a motion vector for the first group and a motion vector for the second group between which the allocation has been performed by the allocation section; and a detection section which detects a motion vector of the frame data by calculating a single motion vector based on the motion vector for the first group and the motion vector for the second group calculated by the motion vector calculation section in accordance with a ratio between a number of correlation detection blocks which are allocated to the first group and a number of correlation detection blocks which are allocated to the second group by the allocation section, wherein the detection section comprises:
