Abstract:
A high efficiency coding device for receiving m number of images A and outputting coded data of n number of images B as coded data of the, m number of images A, comprising:a pre-processing portion for dividing input image data of the m number of images A both horizontally and vertically into a predetermined number of macroblocks or coding blocks which are both horizontally and vertically smaller than the input image data, and generating output image data representative of the n number of images B by rearrangement of the image data of the m number of images A, where m&gE;1 and n&gE;2; and a high efficiency coding portion for receiving the image data representative of each image B, and performing high efficiency coding on the image data representative of each image B to generate coded data of each image B, the code amount of each prescribed image area of the n number of images B being controlled to be a predetermined value, wherein the image data of the m number of images A divided into the macroblocks or coding blocks is distributed throughout the prescribed image area of the n number of images B so that the divided image data of the m number of images A is disposed uniformly in each prescribed image area, and wherein any portion of the prescribed image area which lacks data of a macroblock or coding block of the m number of images A is provided with dummy coding unit data.
