ABSTRACT:
A video presentation system is provided which permits a process in which, when an object in motion video image is handled, an action relating to the object is executed, without increasing load on a central processing unit or a memory. Subject-of-operation information, which defines objects to be handled by a user in relation to each of frames of video data at a transitional phase of time-varying motion of each object, is stored in video operation information retaining means, and when a user operation takes place, the frame position of a currently reproduced video image is acquired from video driving/processing means while screen coordinates of the object are acquired from a coordinates specifying device. Based on the acquired data, video operation information processing means searches the subject-of-operation information to identify the object handled by the user. The subject-of-operation information retains only information associated with each transitional phase of motion of the object, whereby the size of information can be reduced, thus permitting the object specifying process and a like process to be executed at high speed.
