Abstract:
1. An image pickup apparatus comprising: an image pickup element including a plurality of focus detection pixels that receive light passing through a part of an area of an exit pupil of an image pickup lens and perform photoelectric conversation of the received light to generate a signal for a focus detection; a focus detector configured to perform the focus detection based on the signal output from the focus detection pixels corresponding to a focus detection area; a memory configured to store information of a defective pixel that exists in the focus detection pixels; and a setter configured to set a range of F-number to satisfy a predetermined condition based on the information of the defective pixel that is stored in the memory, wherein, when the defective pixel exists in the focus detection pixels corresponding to the focus detection area, if an F-number that is set during the photoelectric conversion to generate the signal for the focus detection is within the range of F-number set by setter, the focus detector performs the focus detection by using the signal output from the defective pixel, and if the F-number is out of the range of F-number set by the setter, the focus detector performs the focus detection without using the signal output from the defective pixel.
