Claim of US Patent No. 9,736,354

1. A control apparatus for controlling an image pickup apparatus including an image sensor that has a plurality of pixel portions
respectively having a plurality of photoelectric conversion portions and outputs an image signal from the photoelectric conversion
portions, the control apparatus comprising:
one or more processors; and
at least one memory coupled to the one or more processors, the at least one memory having instructions stored thereon which,
when executed by the one or more processors, cause the control apparatus to:

calculate a first correlation information between image signals, which are respectively output from one of the pixel portions
positioned in one of a plurality of first regions;

perform focus detection on the basis of a result of the calculating of the first correlation information;
calculate second correlation information between image signals, which are respectively output from the one of the pixel portions
positioned in one of a plurality of second regions, wherein the one of the second regions includes a region near the one of
the first regions, is larger than the one of the first regions, and corresponds to the one of the first regions;

calculate distribution information corresponding to an object distance on the basis of a result of the calculating of the
second correlation information; and

control the calculating of the second correlation information and the calculating of the distribution information on the basis
of the calculated first correlation information.
