1. An imaging apparatus comprising:
a focus lens driving unit that drives a focus lens;
a hardware processor; and
a memory for storing instructions to be executed by the hardware processor, wherein, when the instructions stored in the memory are executed by the hardware processor, the imaging apparatus functions as:
a tilt angle driving unit that tilts an imaging device to change a tilt angle between the imaging device and a plane that is orthogonal to an optical axis of an imaging optical system;
an acquiring unit that acquires position information of a first area of an image and position information of a second area of the image, wherein the first area and the second area are designated by a user, wherein the position information includes distance from a position corresponding to a tilt axis in the image to the first area and distance from the position corresponding to the tilt axis in the image to the second area, wherein the first area is above the position corresponding to the tilt axis in the image, the second area is below the position corresponding to the tilt axis in the image;
a first determining unit that determines a defocusing amount of the first area and a defocusing amount of the second area;
a second determining unit that determines the tilt angle and an amount of driving of the focus lens on the basis of the position information and the defocusing amounts of each of the first area and the second area; and
a control unit that controls the tilt angle control unit to incline the imaging device to the tilt angle determined by the second determining unit and controls the focus lens driving unit to drive the focus lens by the amount of driving of the focus lens determined by the second determining unit.
