Solid state imaging apparatus.

摘要

A solid state imaging apparatus includes a plurality of celles formed on a semiconductor substrate and produces a video signal representing an optical image of an object. Each cell comprises a photosensitive first diode, a second diode connected to the first diode and a switching element connected to the connection point of the first and second diodes for reading out charge signals from the first diode under the control of a read pulse. To one of the first and second diodes a blooming supression pulse is supplied in synchronism with the read pulse so as to enlarge the dynamic range of the imaging apparatus.
