Abstract
A solid-state imaging device in which the potential of a signal line, which is obtained before a pixel has an operating period, is fixed to an intermediate potential between a first power-supply potential and a second power-supply potential.
Claims20
An imaging device comprising:
- a plurality of pixels, each of the plurality of pixels including
- a photoelectric conversion element,
- a floating diffusion,
- a transfer transistor configured to supply a charge from the photoelectric conversion element to the floating diffusion,
- a reset transistor configured to supply a first voltage to the floating diffusion, and
- an amplifying transistor configured to output an analog signal corresponding to a potential of the floating diffusion to a vertical signal line;
- and
- a plurality of column processors, each of the plurality of column processors configured to receive the analog signal through the vertical signal line and convert the analog signal into a digital signal,
- wherein each of plurality of column processors includes a fixing transistor configured to apply a predetermined voltage to the vertical signal line.
