Abstract

The embodiment of the invention discloses a brightness calibration method and device, a storage medium and a terminal. The method comprises the steps of acquiring a current brightness value detected by a current light sensor; determining a backlight level corresponding to the current brightness value from a brightness storage set based on the current brightness value, wherein the brightness storage set comprises the brightness value detected by the brightness sensor and the backlight level corresponding to the brightness value; determining a light leakage brightness value of a backlight sourceaccording to the backlight level and the maximum light leakage value of the light sensor; and determining the actual brightness value of the current ambient light based on the current brightness value and the light leakage brightness value. According to the embodiment, the influence of light leakage of the backlight source of the display screen on reading of the light sensor is compensated and corrected through an algorithm; the effect of correcting the light sensor is achieved; the actual brightness value of the current ambient light can be detected; the terminal can conduct brightness adjustment according to the actual brightness value; and the backlight adjustment accuracy of the terminal can be effectively improved.

Description

technical field [0001] The present application relates to the application field of mobile terminals, in particular to a brightness calibration method, device, storage medium and terminal. Background technique [0002] Currently, a mobile terminal can implement an automatic brightness calibration function, and this function needs to work in conjunction with a Light Sensor (light sensor). [0003] In related technologies, full-screen mobile terminals are mainstream products. When matching LCD (Liquid Crystal Display, liquid crystal display) full-screen mobile terminals, due to the limited space at the top, most of them choose to use the light-transmitting solution of narrow slit Light Sensor. However, this solution is easily affected by light leakage from the LCD backlight, resulting in a large deviation between the Light Sensor readings and the actual ambient light, and the degree of light leakage between individuals is different, and the degree of influence on the Light Sens...
