1. An image pickup apparatus comprising:
a tilt driving unit configured to tilt an image sensor to change a tilt angle that is an angle between an imaging plane of the image sensor and an orthogonal plane orthogonal to an optical axis of an imaging optical system;
a focus driving unit configured to drive a focus lens in the imaging optical system to change a focus position; and
at least one processor or circuit configured to perform a function of at least one of:
an object detecting unit configured to detect a plurality of objects in an image that is captured by the image pickup apparatus;
a defocus amount determining unit configured to determine a defocus amount for each of the plurality of objects detected by the object detecting unit;
a selecting unit configured to select at least two objects from among the plurality of objects detected by the object detecting unit, which are to be used to determine the tilt angle and the focus position, based on at least one of (a) detected sizes of the plurality of objects detected by the object detecting unit, (b) detected positions of the plurality of objects detected by the object detecting unit, and (c) the defocus amounts of the plurality of objects determined by the defocus amount determining unit;
a determination unit configured to determine the tilt angle and the focus position based on the defocus amounts of the at least two objects selected by the selecting unit, and
a control unit configured to control the tilt driving unit and the focus driving unit based on the tilt angle and the focus position determined by the determination unit.
