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.
Claims14
An imaging device, comprising:
- a first substrate including a pixel array;
- and
- a second substrate including:
- a first terminal region including:
- a first pad electrode configured to receive a first voltage, and
- a second pad electrode configured to receive a second voltage different from the first voltage, wherein the first voltage is a ground voltage;
- a voltage sensor region including a voltage sensor coupled to the first pad electrode and the second pad electrode;
- a readout circuit region including an AD converter coupled to the voltage sensor;
- and
- a second terminal region including a third terminal configured to output an error flag based on an output of the AD converter, wherein
- the voltage sensor region is between the first terminal region and the readout circuit region in a plan view, and
- the second terminal region is on a side opposite to the first terminal region with respect to the readout circuit region in the plan view.
