Method for adjusting display backlight with aid of ambient light brightness detection and time detection, and associated apparatus and associated computer program product

Abstract

A method and apparatus for adjusting display backlight and an associated computer program product are provided. The method is applied to an electronic device. The method includes the steps of: utilizing at least one light sensor of the electronic device to detect ambient light; and performing a plurality of detection operations to selectively control the electronic device to enter a specific mode to adjust brightness level of a backlight module of a display panel of the electronic device. The detection operations includes: detecting whether the ambient light is less than a predetermined ambient brightness threshold value for a time period; and detecting whether a length of the time period reaches a predetermined time threshold value. For example, the specific mode can be a low-light mode, which is suitable for a user who has stayed in the dark for a time period (e.g. tens of minutes, or one or more hours).
