Abstract
An image data processing apparatus for storing a multi-valued image data inputted from an image scanner as a plural image data of various resolutions and applying them for tasks, such as printing and displaying. After the conversion by the resolution converting device to a multi-valued image of low resolution, the data is binarized by the binarization circuit and stored after the encoding by the encoding circuit. Meanwhile the encoded data is decoded as the binary data by the decoding circuit and then inputted to a display screen. The image scanner includes the first gradation converting device for converting the intermediate density area of the image data to a specific high or low density. Therefore, it is possible to increase the compression rate at the time of the encoding of the display image data.
