ABSTRACT:
An image processor performs a processing method which includes (a) reading out hierarchical-encoded binary image data stored in a storing medium, (b) decoding the binary image data read out in the step (a), (c) performing a multi-level generation to the binary image data decoded in the step (b), and (d) causing a display device to display an image, on the basis of the data decoded in the step (b) or the data multi-level generation processed in the step (c), wherein, in a case of causing the display device to display the image on the basis of data having a resolution which is higher than the resolution of the display device, the image is displayed in the step (d) after the binary image data is multi-level generation processed in the step (c), thereby preventing deterioration of the image when the image data stored in the storing medium is output.
