IMAGING APPARATUS AND CONTROL METHOD AND PROGRAM OF IMAGING APPARATUS

摘要

An imaging apparatus having an image formation optical system having a lens for focus adjustment of an optical image of an object and an imaging unit for picking up the formed optical image and generating a pixel signal from which a refocus image can be generated includes: a calculation unit for obtaining information of the object the optical image of which is picked up by the imaging unit and calculating, based on the obtained object information, a range of a lens position at which the refocus image of the object being in-focus can be generated; a prediction unit for predicting, based on the lens position range, a change of the calculated lens position at which the refocus image of the object being in-focus can be generated; and a determination unit for determining a drive position of the lens based on a prediction result.

1. An imaging apparatus having
an image formation optical system having a lens for performing a focus adjustment of an optical image of an object and an imaging unit configured to pick up the optical image formed by the image formation optical system and generate a pixel signal from which a refocus image can be generated, comprising: a calculation unit configured to obtain information of the object the optical image of which is picked up by the imaging unit and calculate, on the basis of the obtained information of the object, a range of a position of the lens at which the refocus image of the object being in-focus can be generated; a prediction unit configured to predict, on the basis of the range of the lens position, a change of the calculated lens position at which the refocus image of the object being in-focus can be generated; and a determination unit configured to determine a drive position of the lens on the basis of a result of the prediction.
