IMAGE SIGNAL PROCESSING CIRCUIT AND IMAGE PICKUP DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To smoothly perform operation switching between respective solid-state image pickup elements. SOLUTION: A first sold-state image pickup element 20a catches a first subject image to generate a first image signal Ya (t). A second solid-state image pickup element 20b catches a second subject image to generate a second image signal Yb (t). A selection circuit 26 synchronizes with the operations of the first and second solid-state image pickup elements 20a and 20b and alternately selects and outputs the first and second image signals Ya (t) and Yb (t). A digital processing circuit 29 stores first exposure data EDa generated in accordance with the first image signal Ya (t) in a first register 33a and second exposure data EDb generated in accordance with the second image signal Yb (t) in a second register 33b.
