Image processing apparatus, image processing method, and storage medium for performing image restoration

An image processing apparatus comprising:

• a first acquisition unit configured to acquire a captured image captured by an imaging system;
• a second acquisition unit configured to acquire first image restoration information about an image restoration process that is possibly performed by the imaging system;
• a display unit configured to display a user interface for receiving an input of an editing strength of an image restoration filter for correcting image deterioration caused by the image forming system, in an editing-allowed range that changes according to the first image restoration information acquired by the second acquisition unit;
• and
• a correction unit configured to, using the image restoration filter edited based on an editing strength input by the user, correct the captured image acquired by the first acquisition unit.

An image processing method comprising:

• acquiring, as first acquiring, a captured image captured by an imaging system;
• acquiring, as second acquiring, first image information about a sharpness reduction that occurs in the captured image and is caused by the imaging system;
• specifying a restoration process according to the first image information on the captured image;
• acquiring second image information about a sharpness reduction caused by an image forming system for forming an image on a recording medium based on the captured image;
• setting, based on the first image information and the second image information, image restoration information for correcting at least either of image deterioration caused by the imaging system and image deterioration caused by the image forming system;
• and
• correcting the captured image by a restoration process using the image restoration information.
