1. An imaging apparatus comprising: an imaging unit to collect light input through a lens and sensing an image continuously; a storage unit to store an acquisition condition and the continuously sensed images; a control unit to designate a plurality of objects in one of the continuously stored images, to analyze respective motion of the plurality of objects in the continuously stored images, and to predict a moment of acquisition at which the motion corresponds to the acquisition condition; and a shutter control unit to control the imaging unit to perform imaging at the predicted moment of acquisition, wherein the acquisition condition is a condition set to perform the acquisition at a time point where collision occurs between the plurality of objects, and wherein the control unit calculates moving traces and moving speeds of the plurality of objects and determines the time point where it is predicted that the collision occurs between the plurality of objects as the moment of acquisition.
