Abstract
When dividing a video signal composed of horizontal H pixels and vertical V pixels into blocks of (m.times.n) pixels composed of horizontal m pixels and vertical n pixels, when the number of horizontal pixels or the number of vertical pixels is not equal to an integer multiple of m or n, respectively, the video signal is first divided into blocks of (m.times.n) pixels and sub-blocks of a smaller size. Then, a plurality of sub-blocks are put together to make up a block of (m.times.n) pixels.
