Abstract
PURPOSE:To obtain correct digital video signal, by providing the first charge generation section producing the charge proportional to the amount of incident light and the second charge generation section producing the comparison charge sampled based on the amount of incident light, and the comparator comparing those, on the same semiconductor substrate. CONSTITUTION:On the same semiconductor substrate, the photo electric conversion section 1, a pair of charge transfer section and transfer open and close electrodes 2, 3, 4 and 5, charge production section 6, charge contact part 7, and digital comparator 8 are respectively formed. Whith this constitution, the conversion section 1 producing the signal charge corresponding to the light image emitted consists of a plurality of photo sensing elements 11a to 11b and 12a to 12h, and the transfer sections 2 and 3 are made to meandering shape transfer channel type, and at one end of the trandfer section 3, the charge production section 6 is formed. Further, the signal charge is added acoording to the transfer operation, it is fed to the digital comparator 8, where the signal charge and the comparison charge are compared, and correct digital video signal can be outputted.
