Abstract
Provided is an imaging device including a signal output unit configured to output a predetermined signal and a switch unit configured to output either an output from the signal output unit or an output from a pixel array configured to output a pixel signal by photoelectric conversion in a switching manner. The imaging device further includes a signal processing unit configured to execute signal processing using an output from the switch unit.
Claims16
An imaging device, comprising:
- a first pixel of a pixel array, the first pixel configured to output a first pixel signal;
