ABSTRACT OF THE DISCLOSURE An image processing system is characterized in that a plurality of image processing devices having different resolutions are included. An original image to be sent from a selected image processing device is constituted by a base image corresponding to the lowest resolution, and one or more error compensation data corresponding to resolutions changing stepwise from the resolution of the base image to that of the original image. The base image is generated by reducing stepwise the resolution of the original image. The error compensation data is generated by predicting from either a lower resolution image whose resolution is lower than that of the original image, or, the base image, a higher resolution image whose resolution is one step higher, and by encoding error between the predicted image and an actual higher reso- lution image. When the original image is to be sent to another selected image processing device, image data only up to the one having a resolution of another device are sent.
