Image processing apparatus for reducing influence of fine particle in an image, control method of same, and non-transitory computer-readable storage medium

A method of controlling an image processing apparatus that processes image data obtained by image capturing performed by an image-capturing unit, the method comprising:

• a first setting step of setting a first parameter for performing processing for removing an influence of a fine particle component based on the image data;
• a first image processing step of performing fine particle removal processing based on the first parameter set in the first setting step;
• a second setting step of setting a second parameter differing from the first parameter;
• a second image processing step of performing fine particle removal processing based on the second parameter set in the second setting step;
• a third setting step of setting a region for which the first image processing step is to be used and a region for which the second image processing step is to be used;
• and
• a generation step of generating image data from which an influence of fine particles is removed by applying a result from the first image processing unit and a result from the second image processing unit to the respective regions set by the setting unit
• wherein the second parameter is a parameter for removing the fine particle component to a further extent compared to the first parameter, and
• the third setting step includes:
• a detection step of detecting an object to be detected from image data obtained from the first image processing step;
• and
• a determination step of determining a region in which an object was detected in the detection step and a region in which no object was detected in the detection step, and
• sets the region in which no object was detected as a processing target of the second image processing step.
