ABSTRACT:
A multi-dimensional image compression & decompression method that can compress and decompress image information at high efficiency in the case of image that have different numbers of picture elements on the sending and receiving sides and for image information such as three-dimensional brightness information and the like that includes two-dimensional brightness information and a time axis, extracts local maximum brightness points and local minimum brightness points and sudden change points makes them characteristic points of the image, and uses the local maximum brightness points and local minimum brightness points and sudden change points for the transfer, recording and regeneration of the image. In addition, an apparatus configured so as to include a resistor mesh is used when there is the regeneration of the image, so that the calculations for the decompression of multi-dimensional images are facilitated. By this, it is possible to easily realize high compression in accordance with the amount of information of the image, and irrespective of the physical conditions such as differences in the number of picture elements configuring between the original image that is to have compression of the image information performed, and the reproduced image that is obtained through decompression.
