1. 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; and
a flag generator configured to generate a first error flag based on the first detection voltage data and first reference voltage data, wherein
the first reference voltage data has a determined range, and
the first error flag is set to a ground voltage based on a determination that the first detection voltage data is outside the determined range.
