1. A system for displaying image recognition processing suitability, comprising: a memory comprising instructions; one or more processors configured to execute the instructions to: evaluate a resolution of a monitoring target object in an image of a monitoring target region, the evaluation being performed for each of a plurality of locations where the monitoring target object is placed within the monitoring target region, excluding a presence area of an obstacle; calculate, for each of the plurality of locations, a resolution evaluation value based on the resolution; evaluate a gazing point angle, the gazing point angle denoting an angle that a ground forms with a straight line passing through a location of a camera and a gazing point in the monitoring target object, the evaluation being performed for each of the plurality of locations; calculate, for each of the plurality of locations, a gazing point angle evaluation value based on the gazing point angle; calculate, for each of the plurality of locations, a suitability based on the resolution evaluation value and the gazing point angle evaluation value, the suitability indicating a suitability degree for image recognition of the image with the monitoring target object at a respective location; and display the plurality of locations within the monitoring target region in a mode commensurate with the suitabilities; wherein the monitoring target region is a region in a physical space subject to an image recognition process.
