Image pickup apparatus and control method thereof

摘要

An image pickup apparatus capable of highly efficiently realizing optical corrections of various aberrations while reducing the load imposed on a central processing unit (CPU). A plurality of optical correction units apply optical correction processes to a plurality of aberrations in an optical system. A time period assigned for the optical correction processes and a time period required for the optical correction processes are acquired. Priorities of the plurality of optical correction units are decided if the time period required for the optical correction processes is longer than the time period assigned for the optical correction processes. The plurality of optical correction units execute the optical correction processes according to the decided priorities.

主权项

1. An image pickup apparatus comprising an optical system, the image pickup apparatus comprising:
a plurality of optical correction units that apply optical correction processes to a plurality of aberrations in the optical system, respectively; a first acquisition unit that acquires a time period assigned for the optical correction processes; a second acquisition unit that acquires a time period required for the optical correction processes; a determination unit that determines whether or not the time period required for the optical correction processes is longer than the time period assigned for the optical correction processes; a decision unit that decides priorities of the plurality of optical correction units if the time period required for the optical correction processes is longer than the time period assigned for the optical correction processes; and an optical correction execution unit that causes the plurality of optical correction units to execute the optical correction processes according to the decided priorities.
