Method for intelligently regulating screen display effect according to user preference

Abstract

The invention discloses a method for intelligently regulating a screen display effect according to user preference. The method comprises steps of setting an ambient brightness grade standard and a screen usage effect configuration unit to guarantee that a standard configuration and a display effect parameter configuration of the ambient brightness conform to a user's habit, when ambient brightness is detected to be changed, performing comparison matching on detected ambient brightness and N brightness level references configured by the user to determine what level that current brightness has achieved and call corresponding parameters in an ambient brightness level standard and a usage effect configuration unit, comparing the current display effect parameter with expected effect parameters after ambient brightness detection and matching to determine an adjustment step length of each parameter, respectively and progressively changing the effect parameters according to a fixed cycle and comparing the effect parameters with the expected parameters until achieving an expected value. The whole process of the method is a progressive changing process and does not cause abrupt change, and meanwhile, the method fully considers an effect on a display effect which is caused by parameters like color saturation, etc.

Description

technical field [0001] The invention relates to a method for intelligently adjusting the display effect of a screen according to user's preferences, in particular to a screen of a vehicle navigator. Background technique [0002] The human eye's ability to perceive brightness will change with the change of the ambient brightness. When the human eye looks at the screen for a long time, it needs to adjust the screen background brightness with the change of the ambient brightness. When the ambient brightness increases, the screen brightness must also increase to match the changes in the human eye's perception of brightness. The brightness is similar to or lower than the ambient brightness, making the images on the screen difficult to recognize. On the contrary, when the ambient brightness decreases, the background brightness of the screen must be reduced at the same time, so as to avoid the excessive contrast between the background brightness of the screen and the ambient brigh...

AI Technical Summary

Problems solved by technology

The existing technology can automatically adjust the display brightness and contrast of the screen according to the brightness of the environment. It does not consider the usage habits of different users, nor does it consider the impact of the adjustment process on the user's comfort (such as parameter mutations, etc.), and it does not consider the screen. The influence of color saturation and other parameters related to screen display effects (such as sharpness, etc.) on users in different brightness and contrast combinations. In this case, because all display elements are not considered as a whole when adjusting, the adjustment effect is not not ideal
