Backlight adjusting system and method based on frontal-view face detection

Abstract

The invention discloses a backlight adjusting system and method based on frontal-view face detection. The system comprises an image collecting module, an information processing module and a display driving control module, wherein the image collecting module is used for collecting head image or video information of a user by image collecting equipment as source information of information processing; the information processing module is used for processing the head image or video information collected by the image collecting module, identifying and capturing a face image, judging whether the face image is an image of a frontal-view face or not, controlling backlight brightness of a display screen according to a judging result and transmitting a control signal to the display driving control module; and the display driving control module is used for receiving the display screen backlight brightness control signal transmitted by the information processing module and adjusting the backlight brightness of the display screen.

Description

technical field [0001] The present invention relates to the technical fields of sensor technology, image processing, etc., and specifically relates to a backlight adjustment system and method based on front face detection. Background technique [0002] Concern for consumers' psychological emotions and designs based on consumers' habits are the affirmation and perfection of the concepts of "people-oriented" and "humanized design", and are indispensable aspects of today's product design. [0003] In the smart terminal devices we come into contact with daily, such as laptops, mobile phones, pad products, audio and video players, and embedded terminals for various industrial applications, LCD screens are important system components, and their clarity is getting better and better. The higher the size, the larger the size, and at the same time the power consumption of the LCD screen is becoming more and more obvious. Turning off the backlight of the LCD screen in time is one of th...

And it takes a few seconds for the terminal to return to the normal display brightness from the energy-saving mode every time, which will affect the continuity of the user's thinking and cause inconvenience during use

[0009] 2. On mobile phones or pads, users may be reading documents, browsing web pages, or appreciating pictures. Depending on the user's interest in the content of the page, the time spent by the user on each page may vary. , for the page that the user is interested in, it may take a long time. During this process, the user must also frequently input to the terminal system to avoid the terminal from reducing the brightness of the display screen or turning off the display screen.

The existing terminal backlight control method cannot automatically and intelligently adjust the off time of the backlight according to the usage scene, but must rely on the frequent input of the user, which causes inconvenience to the user and greatly reduces the user-friendliness of the product
