Abstract
An image processing apparatus includes an information acquisition unit configured to acquire first optical information outside an image circle of an imaging optical system, and a processing unit configured to perform sharpening processing, based on the first optical information, for an input image generated by imaging using the imaging optical system. The first optical information is optical information generated based on second optical information within the image circle of the imaging optical system.
Claims19
An image processing apparatus comprising:
- at least one processor or circuit configured to execute a plurality of tasks including:
- an information acquisition task configured to acquire first optical information outside an image circle of an imaging optical system;
- and
- an image processing task configured to perform sharpening processing, based on the first optical information, for an input image generated by imaging using the imaging optical system,
- wherein the first optical information is generated based on second optical information within the image circle.
A lens apparatus attachable to and detachable from an imaging apparatus, the lens apparatus comprising:
- an imaging optical system;
- a memory configured to store first optical information outside an image circle of the imaging optical system;
- and
- a communicator configured to transmit the first optical information to the imaging apparatus,
- wherein the first optical information is used for sharpening processing for an input image generated by imaging using the imaging optical system, and is generated based on second optical information within the image circle.
An image processing method comprising:
- acquiring first optical information outside an image circle of an imaging optical system;
- and
- performing sharpening processing, based on the first optical information, for an input image generated by imaging using the imaging optical system,
- wherein the first optical information is generated based on second optical information within the image circle.
