摘要

The system (1) has a register (100) for storing image information with data input update frequency. A display mode calculation unit generates display mode control signal based on image characteristic allocation of the image information. A display device (12) has a display-panel (122) with pixel units. A control circuit (120) controls display mode and a controlling mode of the display-panel based on the control signal for adjusting display update frequency of the display-panel by using a frequency adjusting unit (102).
