Abstract
A control apparatus for processing image data acquired through an imaging optical system and an image sensor acquires first information corresponding to a magnification that is different according to an image height and second information corresponding to a magnification that is constant regardless of the image height, the first information and the second information being associated with the imaging optical system, and processes the image data using the first information and the second information to reduce image point movement at an out-of-focus position of the imaging optical system.
Claims14
A control apparatus for processing image data acquired through an imaging optical system and an image sensor, the control apparatus comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to:
- acquire first information corresponding to a magnification that is different according to an image height and second information corresponding to a magnification that is constant regardless of the image height, the first information and the second information being associated with the imaging optical system, and
- process the image data using the first information and the second information to reduce image point movement at an out-of-focus position of the imaging optical system.
A lens apparatus comprising:
- an imaging optical system;
- a memory configured to store first information corresponding to a magnification that is different according to an image height and second information corresponding to a magnification that is constant regardless of the image height, the first information and the second information being associated with the imaging optical system, and
- a communication unit configured to transmit the first information and the second information to an image pickup apparatus in response to a request from the image pickup apparatus,
- wherein the first information and the second information are information that is used to process image data from an image sensor so as to reduce image point movement at an out-of-focus position of the imaging optical system.
A control method for processing image data acquired through an imaging optical system and an image sensor, the control method comprising:
- an acquiring step of acquiring first information corresponding to a magnification that is different depending on an image height and second information corresponding to a magnification that is constant regardless of the image height, the first information and the second information being associated with the imaging optical system, and
- a processing step of processing the image data using the first information and the second information to reduce image point movement at an out-of-focus position of the imaging optical system.
