ABSTRACT:
A motion vector detecting device re-arranges the pixel values which make up an initial block for color-difference signals, allowing for their superimposition, to produce a new color-difference signal block having the same number of pixels as that of a luminance signal block. The new color-difference signal block and a luminance signal block are respectively compared with a block for a reference image signal to perform block matching.
