Picture producing apparatus

摘要

A picture producing apparatus alternately operates in mutually different first and second time periods, so as to make access to picture information at a high speed and process the picture information in real time. In the first time period, the picture producing apparatus arranges the picture information which is transmitted into a predetermined format, detects and corrects error in the picture information and writes the picture information into a first memory, and reads picture data stored in a second memory. On the other hand, in a second time period, the picture producing apparatus reads the picture information stored in the first memory, and writes the picture data of the picture information into the second memory depending on control data of the picture information.
