Abstract:
PURPOSE: An encoding method which applies an intra prediction of a macro block variable size division mode and a device thereof are provided to reduce an error of pixel values of a macro block by processing a calculation mode of a representative pixel value of the corresponding macro block in case of applying the intra prediction in a variable size macro block compression mode of a P frame. CONSTITUTION: In case the horizontal and vertical sizes of a macro block are the same or less than a standard size, an encoding device calculates the average value of the macro block and sets up the representative value of the macro block(S520,S522,S529). In case the horizontal and vertical sizes exceed the standard size or at least one of the sizes exceeds the standard size, the device calculates an average value about each minor macro block which is generated by the division of the macro block and sets up a representative value about each of the minor macro block(S530,S532,S526).
