1. An image processing apparatus comprising:
at least one processor; and
at least one memory having stored thereon instructions which, when executed by the at least one processor, cause the image processing apparatus at least to:
acquire reference information which indicates at least one of a number of objects detected from a frame, a density of an object in a frame, or a frame rate; and
track an identical object between frames, wherein
the tracking determines that each of objects for which a difference in a detection position between the frames is smaller than a threshold value corresponding to the reference information is an identical object, and does not determine that each of objects for which a difference in the detection position between the frames is equal to or larger than the threshold value is an identical object.
