This paper tries to recover a color graphics image having original resolution from a lowresolution image by means of an inverse approach. A discrete wavelet transform makes it possible to concentrate an entire image information onto the vicinities of a mother wavelet spectrum region so that it is possible to obtain a rich information compressed image. Our problem is how to recover an image having original resolution from the rich information compressed image. One is a wavelets transform method, and the other is an inverse approach. The former recovers an image with finite accuracy, but the latter is capable of recovering an image with higher accuracy.In this paper, we describe a way of constructing a rich information compressed image having low resolution, and that an inverse approach is able to recover a better image than those of the conventional wavelets transform method.
