Abstract:
A motion image restoring method in an image communicating system for transmitting an image signal continuously over a plurality of frames from a transmitting station and restoring a distorted image in a receiving station by means of an error correction process for correcting errors in the image distorted by transmission error, comprising the steps of:while image data representing an image distorted by a transmission error is being processed in the receiving station, monitoring an occurrence rate of a bit error in the image data detected by an error correction process in the receiving station; andupon completion of receipt of one frame, using a selection means to receive the image data and selectively connect the image data to one of two separate outputs, either an output connected to an in-frame correction processing which corrects a pixel in said image data with reference to other pixels in the vicinity of said pixel, if the occurrence of a bit error is lower than a predetermined rate or an output connected to a refresh request signal transmission processing if the occurrence of a bit error is not lower than the predetermined rate.
