摘要： An imaging apparatus includes an imaging plane phase-difference type first focus detecting unit and a contrast type second focus detecting unit. A saturation detecting unit detects saturation of focus detecting pixels or imaging pixels provided in an imaging element. A brightness detecting unit detects the brightness of an object. If the number of pixels detected by the saturation detecting unit exceeds a predetermined value or the brightness of an object detected by the brightness detecting unit is less than a predetermined value, a CPU controls a focus adjustment operation only using a first detection amount. Alternatively, the CPU controls a focus adjustment operation based on the result obtained by weighting processing of a first detection amount and a second detection amount in response to an increase in the number of pixels of which saturation of the outputs has been detected or a decrease in the brightness of an object.

摘要： An image capturing apparatus performs focus detection based on a pair of image signals obtained from an image sensor including pixels each having a pair of photoelectric conversion units capable of outputting the pair of image signals obtained by independently receiving a pair of light beams that have passed through different exit pupil regions of an imaging optical system. In the focus detection, an f-number of the imaging optical system is acquired, the pair of image signals undergo filtering using a first filter formed from an summation filter when the f-number is less than a predetermined threshold, or using a second filter formed from the summation filter and a differential filter when the f-number is not less than the threshold, and focus detection is performed by a phase difference method based on the pair of filtered image signals.
