Abstract
Provided is an aberration correction method including: picking up images of a particular object at a plurality of focus positions including an in-focus position of the particular object; obtaining an aberration information based on the picked up images; and correcting an aberration based on the aberration information.
Claims19
A method comprising:
- obtaining at least one of an operation count information of an operation device for operating an optical system of a lens apparatus, a shutter operation count in a camera apparatus, and an acceleration value of an acceleration sensor;
- notifying for prompting to carry out a correction of an aberration of an optical system when the at least one of the operation count information, the shutter operation count, and the acceleration value exceeds a predetermined threshold;
- picking up images of a particular object at a plurality of focus positions including an in-focus position of the particular object;
- obtaining an aberration information based on pickup conditions of the optical system and the picked up images;
- and
- correcting the aberration of the optical system based on the aberration information.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method, the method comprising:
- obtaining at least one of an operation count information of an operation device for operating an optical system of a lens apparatus, a shutter operation count in a camera apparatus, and an acceleration value of an acceleration sensor;
- notifying for prompting to carry out a correction of an aberration of an optical system when the at least one of the operation count information, the shutter operation count, and the acceleration value exceeds a predetermined threshold;
- picking up images of a particular object at a plurality of focus positions including an in-focus position of the particular object;
- obtaining an aberration information based on image pickup conditions of the optical system and the picked up images;
- and
- correcting the aberration of the optical system based on the aberration information.
3 more elements
An apparatus comprising:
- a display unit configured to display a notification for prompting to carry out a correction of an aberration of an optical system when an at least one of an operation count information of an operation device for operating an optical system of the apparatus, a shutter operation count in the apparatus, and an acceleration value of an acceleration sensor exceeds a predetermined threshold value;
- a pickup element configured to pick up an image formed by the optical system;
- and
- a controller configured to pick up images of a particular object at a plurality of focus positions including an in-focus position of the particular object, obtain an aberration information based on an image pickup condition of the optical system and the picked up images, and correct the aberration of the optical system based on the aberration information.
