Method, device and equipment for adjusting backlight brightness according to human eye characteristics

Abstract

The invention discloses a method, a device and equipment for adjusting the backlight brightness according to human eye characteristics, and provides a method, a device and equipment for adjusting thebacklight brightness of screens. The method includes acquiring image information and environment information and determining human eye characteristic information according to the image information andthe environment information; acquiring display screen information computing screen backlight reducible proportions according to the display screen information, the human eye characteristic information and the image information and determining screen pixel brightness compensation values according to the proportions; adjusting the backlight brightness according to the screen backlight reducible proportions and adjusting screen pixel brightness values according to the screen pixel brightness compensation values. The human eye characteristic information is related to the minimum amplitude of human eye perceptible brightness variation.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a method for dynamically adjusting the brightness of a display image backlight, a device for dynamically adjusting the brightness of a display image backlight, and a mobile display device capable of dynamically adjusting the brightness of a display image backlight. Background technique [0002] With the development of the information age, mobile electronic devices such as mobile phones and tablet computers have increasingly become an indispensable part of people's lives. When consumers choose mobile products, in addition to factors such as performance and appearance, power consumption (standby time) is also an important consideration. As the display screen is one of the main power-consuming devices of mobile devices, its energy-saving technology has become an important subject of industry research. [0003] At present, the adjustment of the screen backlight of the mobile e...

Problems solved by technology

[0004] However, there is a problem with the above-mentioned CABC backlight control method: it is difficult to determine the most appropriate backlight reduction range when the backlight is lowered twice.

If the backlight is reduced too much, the optical compensation will not be enough to make up for the loss of image quality, and the user will obviously feel that the image quality is dimmed; if the backlight is reduced too little, there is still room for the backlight to be reduced, resulting in waste of power, reducing the standby time of electronic equipment, and affecting user experience.
