Photoelectric conversion apparatus, control method, and storage medium

A photoelectric conversion apparatus comprising:

• a photoelectric conversion element including an avalanche photodiode that photoelectrically converts an optical image;
• at least one memory storing instructions;
• and
• at least one processor that, upon execution of the stored instructions, is caused to:
• (1) generate a first image based on a signal acquired by the photoelectric conversion element;
• (2) acquire first characteristic information related to crosstalk between pixels of the photoelectric conversion element;
• (3) perform first correction processing for correcting the first image using the first characteristic information;
• and
• (4) perform second correction processing for performing pixel interpolation based on the first characteristic information and information of the first image,
• wherein the second correction processing is defect correction processing that interpolates a signal of defective pixels using a signal of surrounding pixels.

A control method for controlling a photoelectric conversion apparatus comprising a photoelectric conversion element including an avalanche photodiode for photoelectrically converting an optical image, the control method comprising:

• generating a first image based on a signal that has been acquired by the photoelectric conversion element;
• acquiring first characteristic information of the photoelectric conversion element;
• performing first correction processing for correcting the first image using the first characteristic information;
• and
• performing second correction processing for pixel interpolation based on the first characteristic information and information of the first image,
• wherein the first characteristic information relates to a crosstalk characteristic between pixels that occurs due to an avalanche luminescence phenomenon.
