FIELD: physics, computer engineering.
SUBSTANCE: invention refers to image capturing device and method of checking. An image capture device is provided, comprising: a plurality of pixels arranged in rows and columns, each pixel outputs the photoelectric conversion signal based on incident light; multiple AD conversion units, and a selection unit configured to perform memory element bit selection, that holds the signal of the first bit of the digital signal among the multiple bit storage elements in the memory unit in each of the multiple AD conversion units.
EFFECT: invention provides reduction of the circuit for a variety of analog-to-digital (AD) circuits arranged in columns and retention unit fault detection.
