CONVERSION UNIT FOR IMAGE RESOLUTION

摘要

PURPOSE:To enable to connect the different video units from the image resolution, by providing a simple circuit converting the resolution. CONSTITUTION:The video signal from the image sensor 11 is in sample-hold and converted into 4-bit digital signal at the A/D converter 14. The output from the A/D converter 14 is stored in the first and second registers 15, 16 in different timing. The digital signal stored is fed to the programmable read only memory PROMs 17- 20 to output the intermediate value data. This intermediate data and the data stored in the first register 15 are fed to the parallel serial shift register 21 and stored in the buffer register 23 serially. The five serial data are outputted every other four sets in the leading of the third clock.
