The present invention is directed to solve a problem that, in an imaging element, complicated control is necessary for reading data for focus detection. A scanning circuit makes a first signal output from a pixel by setting first and second switches to “off” in a period before a first timing, makes a second signal output from the pixel by setting only the first switch to “on” for a predetermined period from the first timing, and makes a third signal output from the pixel by setting the first and second switches to “on” for a predetermined period from a second timing after the first timing. A first AD converter performs AD conversion by comparing the difference between the second signal and the first signal with a reference signal. A second AD converter performs AD conversion by comparing the difference between a third signal and the second signal with the reference signal.
