  • Publication number: 20250238928
    Abstract: An image processing apparatus (10) includes an image processing unit (110) and a risk information generation unit (120). The image processing unit (110) acquires and processes an image generated by an image capture apparatus (20), that is, an image including a plurality of persons. As an example, the image processing unit (110) sets a person being at least part of the plurality of persons as a reference person and computes a distance (first distance) between the reference person and the closest person to the reference person. By using the first distance, the risk information generation unit (120) generates infection risk information in a target region being an image capture target of the image capture apparatus (20).
