Abstract
An imaging device includes: a pixel unit including a plurality of pixels that are arranged in a two-dimensional matrix, each pixel being configured to generate an imaging signal corresponding to an amount of light received and output the image signal; an A/D converter configured to conduct A/D conversion on the imaging signal generated by the pixel unit or on a drive power for driving the pixel unit, to generate a digital signal and output the digital signal to an external unit; a switch that is capable of switching a connection of the A/D converter to the pixel unit or a transmission line for transmitting the drive power; and a first controller configured to control the switch to connect the A/D converter to the transmission line in predetermined timing to cause the A/D converter to output a voltage value of the drive power to the external unit.
