Abstract:
1. An image sensing apparatus comprising: an image sensor including a first pixel group which photoelectrically converts an object image formed by a light beam from an image sensing optical system, and a second pixel group including a plurality of pupil-divided pixels which photoelectrically convert pupil-divided light beam components of the light beam from the image sensing optical system into first and second pupil-divided images; a phase difference detecting unit positioned in the image sensing apparatus to detect a phase difference between the first and second pupil-divided images on the basis of the output from the second pixel group; and a controller positioned in the image sensing apparatus to control the image sensor to output a signal from a predetermined pixel of the image sensor, wherein the image sensor includes a plurality of first lines in each of which N (N is an integer not less than 2) second pixels are arranged, and a plurality of second lines in each of which M (M is a natural number less than N) second pixels are arranged, and wherein the controller controls the image sensor in accordance with whether a sensed moving image is being recorded such that the signal is output from the plurality of first lines during moving image sensing wherein the sensed moving image is not being recorded, and the signal is output from the plurality of second lines during moving image sensing wherein the sensed moving image is being recorded.
