Abstract: An image processing apparatus communicates with an image capturing apparatus. The image processing apparatus includes circuitry to acquire an image of an imaging range of the image capturing apparatus, captured by the image capturing apparatus, recognize an identification that identifies an individual target object included in the image, calculate a trajectory of positions between which the target object included in the image moves, estimate an area in which the target object is present based on the trajectory, acquire the trajectory based on the positions at which the identification of the target object is recognized, and obtain individual area estimation information associating the estimated area corresponding to the acquired trajectory and the identification of the target object.
