Abstract
Provided is an imaging device that includes an imaging unit that performs an imaging operation, a data generator that generates first power supply voltage data corresponding to a first power supply voltage and a flag generation section that generates a flag signal for the first power supply voltage by comparing the first power supply voltage data and first reference data. The first power supply voltage is supplied to the imaging unit.
Claims18
An imaging device, comprising:
- a pixel array including a plurality of pixels, wherein each pixel of the plurality of pixels is configured to generate a pixel voltage;
- a voltage sensor configured to generate a first detection voltage;
- an AD converter coupled to the pixel array and the voltage sensor, wherein the AD converter is configured to generate first detection voltage data based on the first detection voltage;
