Abstract:
1. An image capture apparatus comprising: an image sensor in which image forming pixels which receive light beams passing through an exit pupil of an imaging lens and focus detecting pixels which receive light beams from the exit pupil of the imaging lens which is partly light-shielded are arranged; a first vertical output unit configured to output a signal from each image forming pixel in a vertical direction of said image sensor; a second vertical output unit configured to output a signal from each focus detecting pixel in the vertical direction of said image sensor; a vertical addition unit configured to add signals from a plurality of the image forming pixels in the vertical direction of said image sensor; and a control unit operable in an all pixel readout mode of reading out signals from all pixels of said image sensor without addition and an addition readout mode of making said vertical addition unit add and read out signals from the plurality of image forming pixels, said control unit configured to control, when one of the focus detecting pixels is included in targets for addition in the addition readout mode, said vertical addition unit to add only signals from the image forming pixels excluding the focus detecting pixel, and to make said first vertical output unit and said second vertical output unit simultaneously output the addition signals from the image forming pixels and the signal from the focus detecting pixel.
