摘要

A processing apparatus configured to output an event according to a result of comparison between a size of an object detected within an object detection region of a video image and a threshold value includes a setting unit configured to set the object detection region, a determination unit configured to determine the threshold value based on a size of the set object detection region, and a display control unit configured to cause a detection region figure indicating the object detection region, and a detection size figure with a size corresponding to the determined threshold value to be superimposed on the video image.
