Abstract
PURPOSE: To secure the accurate transmission timing for the picture signals including gradation picture image by providing the photo sensor to detect the scanning timing and also using the analog delay line.
CONSTITUTION: Photo sensor 7 reads out the picture pattern continuously in preceding to photo sensor 8 and then supplies it to analog delay line 14 with taps via reading amplifier 13. Signals Ad1∼Adn of different delay time are obtained from each tap of line 14. While the picture signals of sensor 7 are applied to comparator circuit 16 via reading amplifier 15, and the output B is compared with signals Ad1∼Adn. And the minimum value is decided among comparison results X1∼Xn via deciding circuit 17, and the programming is given to counter 18 via the address to generate the synchronous signals for reading scanning timing.
