The present invention relates to an image signal coding apparatus and method, an image signal transmission method and a recording medium in which an input image signal is divided into a plurality of blocks and a reference image signal is used for carrying out a motion compensative prediction coding to each of the blocks. The present invention is characterized in that a reference image signal is used for each of the blocks to calculate: a motion vector prediction residue of a block for which a motion compensation is carried out; a residue of a block for which no motion compensation is carried out; and an average luminance value of pixel data within a block and a flatness value of the block. For each of the blocks, a magnitude of the aforementioned block motion vector prediction residue is compared to a magnitude of said block residue so that a result of this comparison is used to decide whether to carry out a motion compensation coding. In this process, the average luminance value and the flatness value of the block are used to switch between decision making region division types. According to a result of this decision, a motion compensative prediction coding is carried out for each of the blocks. Thus, even when a prediction residue is small on a flat portion of a image, it is possible to prevent generation of a fixed noise and improve the coding efficiency without deteriorating the image quality.

Apparatus for detecting a motion vector and encoding picture signals. Where a motion vector is obtained by block matching employing a luminance pattern obtained by eliminating dc components from a luminance signal of a picture, and thus containing only ac components, is compared to a motion vector obtained by block matching employing a luminance signal of a picture. An optimum motion vector obtained based upon the result of comparison is employed as a true motion vector for variable length encoding the picture signal. In this manner, a correct motion vector may be detected and employed for variable length coding even in cases where the average luminance of the picture on the screen is varied significantly.
