Title:
SOLID-STATE IMAGE PICKUP DEVICE
Document Type and Number:
Japanese Patent JP2003189318
Kind Code:
A
Abstract:

To provide a solid-state image pickup device that arranges a saturation electric charge amount and white compression in an image between colors and in each color at a low gain and can reduce fluctuation in a dark current at a high gain.

The solid-state image pickup device varies a voltage value or a voltage waveform of an electrode voltage of a solid-state imaging element corresponding to an amplification gain of an amplifier means or a storage time of an output signal of the solid-state imaging element and the amplification gain of the amplifier means so as to vary a dark state superimposition correction wavelength to reduce a low frequency component of a dark current.
