Abstract: PURPOSE: A method for voltage scaling in a mobile terminal is provided to reduce the power consumption of the mobile terminal by lowering the operation clock of the mobile terminal. CONSTITUTION: If a regeneration of a moving picture is requested, a controller gets a motion vector of the requested moving picture(S204). According to the obtained moving picture motion vector, the controller confirms the frame skip of the moving picture(S205). If the frame skip of the moving picture is possible, the operating voltage is supplied to the controller. Therefore, the mobile terminal is operated in the low clock. The controller reproduces the moving picture after the skip of the predetermined frame(S206,S207).
