Abstract

PURPOSE:To establish easy to see a screen of an industrial television camera, by adding an interpolation device. CONSTITUTION:The output signal of a television camera 1 is binarized at a comparator 3, and the signal is sampled and stored in the memory 6 of transmission section. The content of the memory 6 of the transmission section is transmitted to the memory 7 of the reception section. The data recorded in the memory 7 is repetitively read out and interpolated in the level from 1 to 9 stages as to each video element through the surrounding state, by means of weighting circuits 15, 16, 17, 18 and 19 to establish easy to see screen.
