PURPOSE:To obtain a picture memory of simple constitution, by constituting a memory storing input signals so that serial R-Y and B-Y signals are read out in parallel at the same time for the write of both the signals. CONSTITUTION:A Y signal as a TV picture signal is written in a memory 5 of a main memory 4 via an A/D converter 1. R-Y and B-Y signals are made to a serial signal at a switch 12 and A/D-converted at an A/D converter and written in a memory 16. A memory selecting signal is operated with a memory controller 17. Outputs R-Bout and B-Yout of the R-Y and B-Y signals have respective readout oututs at the same time, by operating a memory selection signal with a memory controller 17 and changing the readout address of an address switching circuit 18 in matching with the required readout time. |
