ABSTRACT:
An image processing unit decodes coded data that have been coded and synthesizes the decoded moving image with graphics data. In a case where only graphics data are to be displayed, a bypass unit outputs the graphics data to a display device without use of an image processing unit. A control unit performs control of the supplying of a power supply voltage and a clock to a region containing the image processing unit and performs control of the bypass unit. If processing at the image processing unit is unnecessary, the supply of a power supply voltage or the supply of a clock to the region containing the image processing unit is stopped so as to stop the region and enable reduction of wasteful power consumption.
