Title: Solid-state imaging device
Inventor: ONO KOICHI
IPC: H04N5/359
Filed: 2001-11-02
Abstract: PROBLEM TO BE SOLVED: To enable photographing with a high sensitivity without causing blooming. SOLUTION: When a subject is dark, a video signal output by a solid-state imaging device 4 is weak and the maximum value of the video signal is low, which makes a peak detection circuit 8 generate a lower substrate voltage Vsub and apply it to a semiconductor substrate of the solid-state imaging device 4. When the substrate voltage Vsub is low, an overflow barrier in each photo diode of the solid-state imaging device 4 is formed at a deeper place. Therefore, a signal charge generated by photoelectric transfer of light of long wavelengths to a relatively deep place of the semiconductor substrate is accumulated in a potential well and is effectively used, which increases a photo detection sensitivity of the solid-state imaging device 4. When the subject is bright, on the other hand, a high voltage is applied to the semiconductor substrate of the solid-state imaging device 4.  Therefore, an overflow barrier is formed in a shallow place, which reduces a charge accumulation capacity of each photo diode and prevents blooming.
