Abstract
The present invention relates to an improved solid-state imaging device having pixel amplifiers. The higher definition of the device results in the increase in number of pixels as large as not less than two million. When a solid-state imaging device having such a large number of pixels is provided with pixel amplifiers, there arise various problems associated with a power source and a power supply line as well as a problem inherent to the pixel amplifier type of solid-state imaging device. The present invention provides a solid-state imaging device in which noises or the like are prevented and a picture or image quality having high definition can be obtained, by suppressing a voltage drop of the power supply line and by compensating fluctuations in outputs of the pixel amplifiers.
