Image sensing device and control method thereof

Abstract

An image sensing device includes: a plurality of pixels; and an AD converter that compares a pixel signal output from the plurality of pixels with a slope voltage having a temporally variable potential so as to perform AD conversion on the pixel signal, and switching is performed between a first mode and a second mode according to an imaging condition, the first mode being a mode in which the pixel signal is AD converted by selecting one from among a plurality of slope voltages and comparing the pixel signal with the selected slope voltage, and the second mode being a mode in which the pixel signal is AD converted by comparing the pixel signal with a predetermined slope voltage.
