<p>PURPOSE:To store high frequency RGB signals through the use of small-sized and simple constitution by storing them after the R, G, B signals to be selected and outputted successively are A/D-converted and are sampled by a latch controlled by a dot number counter. CONSTITUTION:Switches S1-S3 are controlled by the selector 1 of a selecting means 6, and the R, G, B signals are supplied successively to an AD converter 2. The output of the converter 2 is outputted to a latch circuit 3 to be controlled at every n-counts of the counter 4 to count dots in a horizontal direction in picture scanning, and is sampled. Then, the digital R, G, B signals of the same picture element are stored in a storage device 5 through the circuit 3. As the result, the high frequency R, G, B signals can be A/D-converted and stored in the storage device whose operating speed is limited by using the small sized and simple constitution which has only one A/D converter.</p> |
