Abstract

The invention discloses a method for calibrating a light perception characteristic curve in a mobile terminal and a device. The method comprises steps of confirming reading value of a light sensor in the mobile terminal, and obtaining image data corresponding to the reading value through a pre-set camera of the mobile terminal, processing the image data and obtaining brightness value of the image data; according to the reading value, the brightness value of the image data and the light perception characteristic curve of the mobile terminal, obtaining the calibration coefficient; according to the calibration coefficient, calibrating the light perception characteristic curve. The method for calibrating the light perception characteristic curve in the mobile terminal and the mobile terminal can calibrate the light perception characteristic curve according to brightness of image data in the pre-set camera in the mobile terminal, so as to exactly reflect the brightness of the environment where the mobile terminal locates.

Description

Technical field [0001] The present disclosure relates to the field of light sensing processing, and in particular to a method for calibrating light sensing characteristic curves in a mobile terminal and a mobile terminal. Background technique [0002] As users have higher and higher performance requirements for mobile terminals, the endurance and screen brightness of mobile terminals have attracted more and more attention from users. The mobile terminal is generally equipped with a light sensor. Under the action of the light sensor, the mobile terminal adjusts the screen brightness according to the light brightness of the environment, so as to increase the screen brightness of the mobile terminal in a bright light environment and reduce the mobile terminal in a dark environment Screen brightness. On the one hand, it can ensure the clarity of the screen and protect users’ eyes; on the other hand, it can save battery energy consumption and improve the endurance of the mobile termi...
