Claim One:
1. An image pickup apparatus comprising: an image sensor that includes a plurality of first pixels and a plurality of second pixels; a focus state detector that detects a focus state according to a pair image based on pixel signals from the plurality of second pixels; a display that displays an image based on pixel signals from the plurality of first pixels; and a controller configured to control output of signal mixed with the pixel signals in a predetermined row from the image sensor, wherein the controller controls the output in a frame such that, in mixing and output signal mode, the signals from the predetermined row of the plurality of first pixels are mixed and are output by a scanning circuit, a signal from a second pixel which is included in the predetermined row is not mixed with the plurality of first pixels and second pixels which are included in the predetermined row and is output by the scanning circuit, wherein the focus state detector detects the focus state according to the pair image based on the pixel signals from the plurality of second pixels without mixing in the frame, and wherein the display displays the image based on mixed pixel signals from the plurality of first pixels in the frame.
