Abstract
An image capturing apparatus includes a pixel array, an AD converter, an output line configured to connect the pixel and the AD converter, a reset unit configured to reset the output line, an amplification transistor configured to amplify a signal from the pixel, a connection unit configured to connect a source of the amplification transistor to the output line, a constant current source, and a control unit configured to, after a voltage of the output line is reset, cause a constant current to flow to the output line and to control to connect a source of the amplification transistor to the output line, wherein the control unit sets a value of the constant current so that the constant current is a lower value than a current required to drive the output line.
