Scene video switch system and scene video switch method

A scene video switch system based on area-of-concern dynamic detection, comprising:

• an input unit configured to input an image currently captured by a video capture unit to serve as a current image;
• a detection unit configured to detect all of interesting elements and latent elements in the current image input by the input unit so as to determine a maximum possible existing area of the interesting elements;
• a state switch unit configured to carry out, by using a predetermined finite state machine, switching between scene states of the maximum possible existing area according to predetermined different scene states and switching conditions;
• and
• a display unit configured to extract, based on a current scene state switched by the state switch unit, an area of concern coinciding with the current scene state from the maximum possible existing area to serve as a scene video for display,
• wherein the predetermined finite state machine is predetermined as a set of scene states, an initial scene state, a set of ending scene states, and a set of switching conditions of the scene states;
• each of the scene states has an initial score, a velocity of change of score with regard to time, and an innate value;
• and each of the switching conditions corresponds to a switching operation.
