Abstract
An imaging apparatus includes: a plurality of analog-digital conversion units that performs parallel processing on a signal of each pixel output in units of a plurality of pixel rows from a pixel array unit in which pixels including photoelectric conversion units are arranged, and converts the signal into a digital signal; a plurality of reference voltage generation units that is provided corresponding to the plurality of analog-digital conversion units and generates a reference voltage used for AD conversion; a voltage setting unit that sets a plurality of pixel voltage levels and outputs the plurality of pixel voltage levels through each of the plurality of analog-digital conversion units; and a computing unit that calculates a correction amount for performing correction on a result of the AD conversion of the signal of each pixel of the pixel array unit. The computing unit calculates the correction amount on the basis of the result of the AD conversion of each of the plurality of pixel voltage levels by each of the plurality of analog-digital conversion units.
