Color temperature adjusting method, device and system based on face recognition

Abstract

The invention relates to color temperature adjusting method and device based on face recognition. The method comprises the following steps of: collecting face image information of a spectator; carrying out analysis treatment on the face image information to obtain the type of the spectator; and according to the type of the spectator, controlling display equipment to carry out corresponding adjustment on a color temperature mode of a display image of a screen. According to the color temperature adjusting method and device based on the face recognition disclosed by the invention, the collected face image information of the spectator is subjected to the analysis treatment to obtain the type of the spectator; the display equipment is controlled to carry out corresponding adjustment on the color temperature mode of the display image of the screen according to the type of the spectator, so as to be adapted to the favors of the spectator to the color temperature mode. The viewing comfort level of the spectator is enhanced. With the adoption of the method, the spectator can adjust the color temperature mode of the display equipment to the best viewing effect without independently operating the display equipment, so that the use is more convenient and the automatic and intelligent degrees are improved.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a method, device and system for adjusting color temperature based on face recognition. Background technique [0002] Color Temperature is a measure of the light color of a light source, and the unit is K (Kelvin). Color temperature has important applications in photography, video recording, publishing and other fields. The color temperature of a light source is determined by comparing its color to a theoretical hot black body radiator. According to Planck's black body radiation law, it can be known that the Kelvin temperature when the thermal black body radiator matches the color of the light source is the color temperature of the light source. [0003] In the current PQ (Picture Quality) adjustment process of LCD TVs, PQ engineers need to pay special attention to color temperature adjustment. At present, most LCD TV companies in the world provide severa...

AI Technical Summary

Problems solved by technology

The current technology only presets several fixed color temperatures into the LCD TV system, and users can only choose manually, so it is impossible to adjust the color temperature of LCD TVs according to different types of users.
