Abstract

The invention relates to a background light adjustment method based on pupil radius detection. The method comprises steps: a background light adjustment device is used to be arranged on an integratedcircuit board of a tablet personal computer for adjusting the background light brightness of a display screen of the tablet personal computer; a data acquisition device is used to be arranged in a front frame of the tablet personal computer for photographing an image in front of the tablet personal computer under operation of a user and also regularly photographing a facial image of the user underno operation of the user; a resolution analysis device is used to be connected with the data acquisition device for receiving the facial image and acquiring the current resolution of the facial imageas an image resolution to be outputted; and a mode control device is used to be connected with the resolution analysis device for selecting a coarse mode enhancement device to carry out correspondingimage enhancement processing on the facial image to acquire a target enhancement image when the image resolution is smaller than or equal to a preset resolution threshold.

Description

technical field [0001] The invention relates to the field of background light adjustment, in particular to a background light adjustment method based on pupil radius detection. Background technique [0002] Tablet PC is also called portable computer (English: Tablet Personal Computer, referred to as Tablet PC, Flat Pc, Tablet, Slates), is a kind of small-sized, portable personal computer, uses touch screen as basic input device. Its touch screen (also known as digital tablet technology) allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse. Users can input via built-in handwriting recognition, an on-screen soft keyboard, voice recognition, or a real keyboard (if the model is equipped). [0003] Due to the rich content and large screen of the tablet computer, users use it frequently and for a long time, but the background light brightness of the display screen of the tablet computer is fixed, and it is not adjusted in time according to ...
