Japanese Patent JP3166976
Kind Code:
B2
Abstract:
PURPOSE:To offer a moving object indication system by which the moving object in a moving image can be easily indicated. CONSTITUTION:A frame image constituting the moving image is successively inputted through an input terminal 301. Then, the previously inputted frame image is delayed for one frame by a frame delay equipment 303, so that the frame image is synchronized with the frame image inputted at that time. Then, a difference between the two frame images is searched by a difference equipment 305, and the result is stored in a differential buffer 306. Afterwards, an area computing element 307 searches the data stored in the differential buffer 306, and detects the existing area of the moving object. The detected existing area of the moving object is compared with an indicated coordinate position in order to judge whether or not the indicated position indicates the moving object.
