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 photosensitive processing, and in particular, to a method for calibrating a photosensitive characteristic curve in a mobile terminal and the mobile terminal. Background technique [0002] As users have higher requirements on the performance of mobile terminals, the battery life and screen brightness of mobile terminals are more and more concerned by 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 brightness of the environment, so that the screen brightness of the mobile terminal can be increased in a bright light environment, and the screen brightness of the mobile terminal can be reduced in a dark environment. screen brightness. On the one hand, it can ensure the clarity of the screen and protect the user's eyes; on the other hand, it can save battery energy consumption and impro...
