<p>A picture image monitoring system wherein picture images of a plurality of monitoring object areas and difference degree information indicative of a rate of a picture image change of each monitoring object area can be transmitted efficiently to a remote location by way of a communication channel and a monitoring operation of the monitoring object areas can be performed accurately and efficiently at the remote location. A transmitting side terminal apparatus and a receiving side terminal apparatus are interconnected by a communication channel. At the transmitting side terminal apparatus, a picture image signal of a monitoring object area photographed is compressed while difference degree information and an identifier are produced, and they are transmitted to the receiving side terminal apparatus by way of a communication line. At the receiving side terminal apparatus, received compressed picture image data, difference degree information and identifier are used to effect detection of a picture image change of a monitoring object area and desired monitoring control. <IMAGE></p> |
