<p>PROBLEM TO BE SOLVED: To satisfactorily calculate a motion vector and to improve a decoded image quality. SOLUTION: When a video inputting device 105 inputs a moving image signal that is photographed by a camera, etc., to a system controller 102, the moving image signal is inputted to a motion detector 107 from the state of a voice encoder 106 and the operation state of a system control controller 104 when an image transfer device 103 is operable. Also, at this time, the state of the system is inputted to an operation amount supervisory device 109 and the processing amount that can be executed by the device 103 is calculated. The detector 107 performs motion detection by using frame memory 108 that stores the preceding decoded image based on this. By dynamically changing the processing amount of the detector 107 in accordance with the state of the system, more detailed motion detection is performed when the decoder 106, etc., does not operate due to the system state.</p> |
