Image processing apparatus, image capturing apparatus, and storage medium

An image capturing apparatus comprising:

• an image capturer configured to generate a first image by ii image capturing through an image capturing optical system;
• and
• an image processing apparatus,
• wherein the image processing apparatus includes;
• an image acquirer configured to acquire a first image generated by image capturing through an, image capturing optical system;
• a filter memory configured to store data relating to multiple image restoration filters are used for an image restoration process and correspond to a mutually different first F-numbers;
• an interpolation data or r configured to store interpolation data corresponding to each of mutually different second F-numbers different from the first F-numbers, the interpolation data relating to art interpolation proportion in an interpolation process;
• and
• an image generator configured to generate, when an image capturing F-number as am F-number for the image capturing is one of the second F-numbers, a second image by performing on the first image a correction process that includes the image restoration process and the interpolation process, respectively using at least one of the image restoration filters corresponding to the -numbers and interpolation data corresponding to the image capturing F-number,
• wherein the multiple first F-numbers are set such that multiple F-number ranges sectioned at the first F-numbers between a minimum F-number and a maximum F-number each settable as the imago capturing F-number include an F-number range corresponding to, a different number of F-number steps from that of another F-number range.

A non-transitory recording medium configured to store a computer program that enables a computer to execute a process for a first image generated by image capturing through an image capturing optical system,

• wherein the process includes the steps of:
• acquiring data relating to multiple image restoration filters that are used for an image restoration process and correspond to mutually different first F-numbers;
• enabling interpolation data to be acquired, which corresponds to each of mutually different second F numbers different from the first F-numbers, the interpolation data relating to an interpolation proportion in an interpolation process, and
• generating, when an image capturing F-number as an F-number for the image capturing is one of the second F-numbers a second image by performing on the first image a correction process that includes the image restoration process and the interpolation process, respectively using at least one of the image restoration filters corresponding to the first F-numbers and the interpolation data corresponding to the image capturing F-number,
• wherein the multiple first F-numbers are set such that multiple F-numbers ranges sectioned at the first F-numbers between a minimum F-number and a maximum F-number each settable as the image capturing F-number include an F-number range corresponding to a different number of F-number steps from that of another F-number range.

A lens apparatus comprising;

• an image capturing optical system;
• a filter memory configured to store data relating to multiple image restoration filters that are used for an image restoration process correspond to a mutually different first F-numbers;
• and
• an interpolation data memory configured to store interpolation data corresponding to each of mutually different second F-numbers different from the first F-numbers, the interpolation data relating to an interpolation proportion in an interpolation process,
• wherein the lens apparatus is configured to provide the image restoration filters and the interpolation data to an image capturing apparatus configured to generate, when an image capturing F-number as an F-number for the image capturing is one of the second F-numbers, a second image by performing on the first image a correction process that includes the image restoration process and the interpolation process, respectively using at least one of the image restoration filters corresponding to the first F-numbers and the interpolation data, corresponding to the image capturing F-number,
• wherein the multiple first F-numbers are set such that multiple F-number ranges sectioned at the first F-numbers between a minimum F-number and a maximum F-number each settable as the image capturing F-number include an F-number range corresponding to a different number of F-number steps from that of another F-number range.
