Abstract:
A motion vector detecting device in which a process, including a first step to reduce each of a gazed block of a present screen and a reference region of a reference screen and search a block most similar to the reduced gazed block in the reduced reference region, and a second step to search a block most similar to the gazed block in a part, including the block searched in the first step, of the non-reduced reference region, detects the motion vector of the gazed block, wherein the gazed block and the reference region are stored in an internal memory, and the searches are executed on the basis of the stored information,the motion vector detecting device comprising an image processing unit that reduces the gazed block and the reference region into a reduced form for use in the search of the first step, and thereafter, transfers the result of the reduction to the internal memory, wherein the reduction is performed by calculating at least one pixel average of two adjoining pixels.
