Abstract

To avoid unintentionally turning off a backlight, a device includes circuitry that is configured to control a backlight to illuminate a display panel of the device; store a first preset time interval for reducing brightness of the backlight; determine that an input has not been received within the first preset time interval; acquire one or more signals from a sensor device corresponding to movement of the device; estimate whether the device is in use based on the one or more signals; and postpone a reduction in the brightness of the backlight based when a result of an estimate indicates that the device is in use.
