Image capturing apparatus, image processing apparatus, control method of image capturing apparatus, and non-transitory computer-readable storage medium

An image processing apparatus comprising:

• one or more processors that execute a program stored in a memory, wherein the program, when executed by the one or more processors, causes the one or more processors to function as:
• a data acquisition unit configured to acquire an image data file including an image signal obtained by capturing an object image formed by light that has passed through an optical member using an electrochromic element and capable of electrically controlling a transmittance of the light;
• an information acquisition unit configured to acquire, based on information recorded in the image data file, information representing a distribution characteristic of a transmittance of the electrochromic element at the time of image capturing;
• and
• a correction unit configured to execute correction processing for the image signal based on the information representing the distribution characteristic.

A non-transitory computer-readable storage medium storing a program configured to cause a computer provided in an image capturing apparatus to function as each unit of the image capturing apparatus,

• wherein the image capturing apparatus comprises an image capturing element configured to capture an object image formed by light that has passed through an optical member using an electrochromic element and capable of electrically controlling a transmittance of the light,
• wherein the image capturing apparatus further comprises one or more processors that execute the program stored in the non-transitory computer-readable storage medium, wherein the program, when executed by the one or more processors, causes the one or more processors to function as:
• a distribution acquisition unit configured to acquire a distribution characteristic of a transmittance of the electrochromic element based on a current value flowing to the electrochromic element, and
• an image processing unit configured to correct an image signal captured by the image capturing element in accordance with the distribution characteristic.

A non-transitory computer-readable storage medium storing a program configured to cause a computer to function as each unit of the image processing apparatus,

• wherein the image processing apparatus comprises one or more processors that execute the program stored in the non-transitory computer-readable storage medium, wherein the program, when executed by the one or more processors, causes the one or more processors to function as:
• a data acquisition unit configured to acquire an image data file including an image signal obtained by capturing an object image formed by light that has passed through an optical member using an electrochromic element and capable of electrically controlling a transmittance of the light;
• an information acquisition unit configured to acquire, based on information recorded in the image data file, information representing a distribution characteristic of a transmittance of the electrochromic element at the time of image capturing;
• and
• a correction unit configured to execute correction processing for the image signal based on the information representing the distribution characteristic.
