Claim Text:
1. An imaging apparatus comprising: an imaging element that includes pixel portions each having a plurality of photoelectric conversion units; a drive unit configured to drive a focus adjusting lens; a first processing unit configured to acquire a signal output by the imaging element and to output a first image signal for a focus detection and a second image signal for the focus detection and an image generation; a second processing unit configured to acquire the second image signal from the first processing unit so as to perform development processing; a calculation unit configured to acquire the first image signal and the second image signal from the first processing unit so as to perform phase difference detection-type focus detecting calculation by correlation calculation between the first image signal and a third image signal generated from the first image signal and the second image signal; and a control unit configured to acquire data indicating the result of the correlation calculation so as to calculate a defocus amount and to control the drive unit so as to perform focus adjustment, wherein the control unit controls the calculation unit, and wherein an output of the data indicating the result of the correlation calculation from the calculation unit to the control unit is intermittently performed at a frequency set for a plurality of image frames in accordance with an output of the second image signal from the first processing unit to the second processing unit.
