1. An information processing system configured to process a captured image captured by an image-capturing apparatus including an infrared cut filter, wherein:
based on the captured image, a defect relating to the infrared cut filter is detected, information on the defect is output,
the image-capturing apparatus is configured to capture an image in (a) a first image-capturing mode with the infrared cut filter effective and in (b) a second image-capturing mode with the infrared cut filter ineffective, and
the defect is detected based on a difference between (a) a first captured image captured in the first image-capturing mode and (b) a second captured image captured in the second image-capturing mode, and
wherein:
in detection of the defect, when the difference between the first captured image and the second captured image is less than a predetermined value, it is determined that the defect occurs in the infrared cut filter.
