DISPLAY DEVICE FOR PLURAL PICTURES

摘要

PURPOSE:To display the plural picture signals of different synchronizing frequencies in the same display by providing an interpolaring or extrapolating synchronous converter to convert the arbitrary picture signal to a picture signal to be synchronized to the prescribed synchronizing frequency. CONSTITUTION:Visual information 61 are synchronized by a synchronizing circuit 1261 so that the signal can be picked up in a pixel unit. The picked-up signal for the pixel unit is converted to a digital signal by an A/D converter 1262. To make the data format or synchronizing frequency the same as that of a picture signal 1214 which acquires visual information 11 from a POC control part 10 through a concerting circuit 121, the comerted digital signal is synchronous by converted with a synchronous converter 1263 by interpolation or extrapolation.
