1. An image processing apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to perform operations comprising:
by processing an image including a plurality of persons, computing, for a person being at least part of the plurality of persons, a first distance being a distance to the closest person to the person;
by using the first distance, generating infection risk information being information about a risk of contracting an infectious disease or a safety factor of not contracting an infectious disease in a target region being a region included in the image;
determining at least one of an orientation of a face of the person and an orientation of a face of the closest person; and
generating the infection risk information by further using a determination result of an orientation of the face,
wherein generating the infection risk information comprises outputting the image as including a mark superimposed over a display of the person, and wherein, in generating the image, any of a color and a line style of the mark depends on the infection risk information.
