METHOD, APPARATUS, AND DEVICE FOR ADJUSTING BACKLIGHT BRIGHTNESS BASED ON HUMAN EYE CHARACTERISTICS

摘要

A method, an apparatus, and a device for adjusting screen backlight brightness. The method includes: obtaining image information and information about an environment; determining human eye characteristic information based on the image information and the information about the environment, where the human eye characteristic information is related to a minimum magnitude of a brightness change perceptible to human eyes; obtaining information about a display screen, calculating a screen backlight decreasable ratio based on the information about the display screen, the human eye characteristic information, and the image information; and determining a screen pixel brightness compensation value based on the backlight decreasable ratio, adjusting backlight brightness based on the screen backlight decreasable ratio, and adjusting the screen pixel brightness value based on the screen pixel brightness compensation value.
