Abstract
A mobile phonecomprises a displayprovided with an LED () that functions as a backlight, a display driver (), etc. The display driver has a CABC (Content Adaptive Brightness Control) function to adjust illuminance of the backlight, an image quality of an image to be displayed, etc. based on the image that is displayed on the display. If a residual battery quantity of a secondary battery () becomes equal to or less that a first threshold value, for example, the CABC function is rendered in an enabled state. Furthermore, if the residual battery quantity becomes equal to or less that a second threshold value, an image parameter such as brightness, contrast, a gamma value, chroma saturation, etc. is changed such that the image that is output to the display driver becomes darker.
