Claim One:
1. An image region segment extraction system, comprising a video device for extracting an image segment from a video image, the video device comprising a video processor configured for: obtaining the video image comprising a plurality of sequential image frames, wherein a size of said video image conforms to a full screen; calculating motion data for the video image based on the sequential image frames obtained from a video camera by calculating an average movement for motion vectors in each of a determined number of the sequential image frames, wherein said average movement comprises a direction and acceleration of an object within the sequential image frames; using the motion data to estimate camera operations associated with the video image; designating a target area as an area within the sequential image frames that captures the object; designating a size of the target area as no larger than half of the full screen of the video image; referring to said camera operations performed under predetermined conditions to estimate the location of a center of the target area in the determined number of sequential image frames using rules related to the estimated camera operations; designating image features in the vicinity of said center target area; designating an image segment comprising the centered target area in which said image features are included; extracting the image segment comprising said target area being an area aimed at by a cameraman, and delivering the extracted image segment to a terminal for display.
