IMAGE PICKUP APPARATUS AND METHOD FOR DETECTING AN ENTRANCE OR EXIT EVENT OF AN OBJECT IN A FRAME IMAGE AND MEDIUM STORING A PROGRAM CAUSING A COMPUTER TO FUNCTION AS THE APPARATUS

An information processing apparatus includes: an object detection unit to detect an object included in a frame image based on a feature amount of the frame image, and generate and output object information concerning the detected object; an event detection unit to detect an event of the object based on the object information output by the object detection unit, and generate and output event concern information concerning the detected event of the object; and a transmission unit to transmit the frame image, the event concern information, concerning the frame image, output by the event detection unit, and time information concerning the frame image, as associating them with others. Thus, even in a case where event detection timing and event occurrence timing are different from each other, it is possible to perform a display by which a user can easily confirm the event.
