Imaging apparatus, control apparatus, and storage medium providing phase difference detection focusing control of an image having a saturated object

A control apparatus comprising:

• a calculation unit configured to calculate a plurality of focus evaluation values each having a different setting condition, based on a pair of image signals in a focus detection area in an image captured by an image sensor configured to output the pair of image signals based on a pair of light fluxes that have passed different exit pupil regions in an imaging optical system that includes a focus lens;
• a detection unit configured to detect a plurality of saturation degrees for each of the plurality of focus evaluation values;
• and
• a focusing unit configured to drive the focus lens by using focus evaluation values for focusing selected based on the plurality of saturation degrees out of the plurality of focus evaluation values,
• wherein the detection unit changes a parameter used to detect the plurality of saturation degrees based on the setting condition,
• wherein at least one processor or circuit is configured to perform a function of at least one of the units.

A computer-readable non-transitory storage medium for storing a computer program that enables a computer to execute a method comprising:

• a calculating step of calculating a plurality of focus evaluation values each having a different setting condition, based on a pair of image signals in a focus detection area in an image captured by an image sensor configured to output the pair of image signals based on a pair of light fluxes that have passed different exit pupil regions in an imaging optical system that includes a focus lens;
• a detecting step of detecting a plurality of saturation degrees for each of the plurality of focus evaluation values;
• and
• a focusing step of driving the focus lens by using focus evaluation values for focusing selected based on the plurality of saturation degrees out of the plurality of focus evaluation values,
• wherein the detecting step changes a parameter used to detect the plurality of saturation degrees based on the setting condition.
