Abstract
A video signal processing system for electronic endoscope, employing a high-sensitivity solid-state image sensor device having an approximately doubled sensitivity along with improved dynamic range and RGB spectral sensitivity ratios and reduced to about 1/2 in size as compared with conventional endoscopic solid-state image sensor devices, the system being arranged to read out therefrom an A-field signal having a preceding line added to each scanning line and a B-field signal having a succeeding line added to each scanning line, store the A- and B-field signals in a field memory, and read out the A- and B-field signals alternately line by line from the field memory as picture data to improve the RGB spectral sensitivity ratios.
