Abstract: In an image data compression method to be employed in coding digital image data whose pixels are represented by n bits and which include 2.sup.n different types of runs, while a run length of a current run is counted, a value representing a run type of the current run is predicted. The prediction is repeated till a predicted value coincides with an actual value of the run type of the current run. When a predicted value does not coincide with the actual value of the run type of the current run, a run length for an imaginary run having the predicted value is regarded as zero and the run length 0 of the imaginary run is entropy coded. On the other hand, when a predicted value coincides with an actual value, the actual run length of the current run is entropy coded.

Abstract: A device for editing and displaying an image uses a medium such as a transparent film or a magnetic card on which are recorded both display data and commands for specifying how the display data should be processed. Such data are received by the device through a camera, a magnetic record reader and/or the like and stored in a memory device. Digital image processing is performed on such stored data according to the commands and an image according to the processed data is displayed.
