Abstract
An image processing apparatus includes at least one memory configured to store instructions, and at least one processor configured to execute the instructions to acquire a captured image obtained using an optical system, and information on an imaging condition corresponding to the captured image, and perform deteriorating processing for the captured image based on an F-number of the optical system, the F-number being included in the information on the imaging condition. A first deterioration amount in the deteriorating processing in a case where the F-number is a first F-number is smaller than a second deterioration amount in the deteriorating processing in a case where the F-number is a second F-number larger than the first F-number.
Claims13
An image processing apparatus comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire a captured image obtained using an optical system, and information on an imaging condition corresponding to the captured image;
- acquire a deteriorating filter based on an F-number of the optical system, the F-number being included in the information on the imaging condition, and
- perform deteriorating processing for the captured image based on the deteriorating filter
- wherein a first deterioration amount in the captured image based on the deteriorating filter in a case where the F-number is a first F-number is smaller than a second deterioration amount in the captured image based on the deteriorating filter in a case where the F-number is a second F-number larger than the first F-number.
An image pickup apparatus comprising:
- an image processing apparatus;
- and
- an image sensor configured to photoelectrically convert an optical image formed by an optical system,
- wherein the image processing apparatus includes:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire a captured image obtained using an optical system, and information on an imaging condition corresponding to the captured image;
- acquire a deteriorating filter based on a F-number of the optical system, the F-number being included in the information on the imaging condition, and
- perform deteriorating processing for the captured image based on the deteriorating filter, and
- wherein a first deterioration amount in the captured image based on the deteriorating filter in a case where the F-number is a first F-number is smaller than a second deterioration amount in the captured image based on the deteriorating filter in a case where the F-number is a second F-number larger than the first F-number.
An image processing method comprising the steps of:
- acquiring a captured image obtained using an optical system, and information on an imaging condition corresponding to the captured image;
- acquire a deteriorating filter based on a F-number of the optical system, the F-number being included in the information on the imaging condition, and
- performing deteriorating processing for the captured image based on the deteriorating filter,
- wherein a first deterioration amount in the captured image based on the deteriorating filter in a case where the F-number is a first F-number is smaller than a second deterioration amount in the captured image based on the deteriorating filter in a case where the F-number is a second F-number larger than the first F-number.
