Claim:
1. An imaging apparatus comprising: an image sensor configured to capture an optical image of an object and output an image including light field data which can be refocused within a refocusable range by image processing; at least one processor configured to detect a focus state of the object and to determine an in-focus position of a specified object on the basis of a result of the detection; a driving mechanism configured to drive a focus lens; and a controller configured to control the driving mechanism to drive the focus lens, wherein, in a case where the image sensor captures a series of images at a plurality of positions of the focus lens, the controller controls the driving mechanism to drive the focus lens to the plurality of positions during the capturing of the series of images so that (1) the determined in-focus position of the specified object falls within the refocusable range of a respective image of the series of images and is a position which is apart from the in-focus position of the focus lens by an amount predetermined by the controller, and (2) a total refocusable range of a predetermined number of images of the series of images is wider than a refocusable range of one of the series of images by a range based on the predetermined amount.
