The present technology relates to an imaging apparatus, a focus control method, and a program, and is to be able to increase focusing precision.
In the related art, it is generally possible to perform an autofocus operation in an imaging apparatus. In the autofocus operation, for example, a range-finding frame which denotes which portion of a subject is to be the subject of focusing is displayed in a viewfinder, and a focus control is performed using a contrast detection method, or a phase difference detection method so that focusing is performed in the range-finding frame.
In addition, in Japanese Unexamined Patent Application Publication No. 2006-58405, a technology is disclosed in which focusing to a specified portion of a subject can be easily performed when performing close-up photography by switching a size of a range-finding frame between a normal mode and a macro mode. Further, in Japanese Unexamined Patent Application Publication No. 2010-237400, a technology is disclosed in which a focus detection is performed using a phase difference detection method by providing a focus detection pixel, for example, a pair of phase difference AF pixels in an imaging element.
