Patent ID: 8195042

Claim:
An imaging apparatus comprising: an imaging unit having a plurality of pixels arranged two-dimensionally in a row direction and a column direction and configured to obtain an image of an object by sequentially scanning a plurality of pixels to read out an image signal while moving the position of a focusing lens; a detection unit to detect an object area in an image obtained by the imaging unit; a setting unit to set an AF area corresponding to the object area detected by the detection unit; and a focusing control unit configured to obtain in-focus states of a plurality of images in the AF area set by the setting unit, the plurality of images being captured by the imaging unit, and based on information about the in-focus states, to perform focusing control of the focusing lens, wherein when the object area is larger than a predetermined size, the setting unit sets an AF area which is smaller than an AF area which corresponds to the object area by decreasing only the size of the object area in the row direction or in the column direction in which a difference occurs in charge readout timing.
