Abstract
An image capturing apparatus includes a pixel portion in which pixels, first and second sample-hold circuits that are two sample-hold circuits arranged with respect to pixel signals output from one pixel, a voltage-current conversion circuit configured to output a difference between the first and second sample-hold circuits, as a current signal, an AD converter configured to convert an output signal of the voltage-current conversion circuit to a digital signal, and a controller configured to perform control such that, a first pixel signal obtained from the pixel is held in the second sample-hold circuit and is AD converted, in a first period, and the first pixel signal and a second pixel signal that are obtained from the pixel are held in the second sample-hold circuit and the held signal is AD converted, in a second period.
