The terminal light sensor calibration method comprises the followingsteps: acquiring a light intensity value collected by a light sensor; collecting images through a camera on the same side as the light sensor; calculating brightness information of a light sensing area of the light sensor and complete brightness information of the images on the basis of the image; calculating a light sensing calibration coefficient according to the ratio of the brightness information of the light sensing area of the light sensor and the complete brightness information of the images; and determining a light intensity value after calibration on the basis of the light intensityvalue and the light sensing calibration coefficient. The terminal light sensor calibration method and device, the terminal and the storage medium provided by the application are used for improving thedetection accuracy of the light sensor.

Description

technical field [0001] The embodiments of the present application relate to terminal technologies, and in particular, to a terminal light perception calibration method, device, terminal and storage medium. Background technique [0002] In order to meet the needs of users in different environments, the display screen of the terminal equipment has the ability to adjust the brightness. content, and when the ambient light is low, lower the display brightness of the display screen so as not to make the screen too bright to irritate the user's eyes. [0003] In current terminal equipment, a light sensor is generally used to detect the intensity of ambient light, which is also called light detection, and the brightness of the display screen is dynamically adjusted according to the light intensity detected by the light sensor. However, the terminal equipment generally adopts a thin and light design, and the optical sensor is embedded in the terminal equipment. However, since the l...

Problems solved by technology

And because the lighting element of the light sensor is located inside the light sensor chip, the light receiving angle of the light sensor is limited, and there may be errors in the light intensity value of the light sensor, which may affect the detection accuracy of the light sensor for light intensity.
