Correction method, device and equipment used for optical sensor, and storage medium

Abstract

The invention discloses a correction method, a device and equipment used for an optical sensor, and a storage medium. The method comprises the following steps of acquiring a reference illumination intensity value output by the optical sensor under standard light source irradiation; acquiring the ratio of the reference illumination intensity value relative to a standard illumination intensity valueunder the standard light source irradiation and taking as the correction coefficient of the optical sensor; acquiring an illumination intensity value to be corrected output by the optical sensor under environment illumination; and taking the product of the illumination intensity value to be corrected and the correction coefficient of the optical sensor as the corrected illumination intensity value of the optical sensor, and according to the corresponding relation of the illumination intensity value of the optical sensor and the backlight brightness of a liquid crystal display screen, adjusting the backlight brightness of the liquid crystal display screen so that the optical sensor outputs the corrected illumination intensity value under the environment illumination. In the invention, a problem that the backlight brightness of the same model of equipment under a same illumination environment is not consistent is solved, and the backlight brightness of the equipment under the same illumination environment is consistent.

Description

technical field [0001] Embodiments of the present invention relate to a calibration technology, and in particular, to a calibration method, device, equipment and storage medium for an optical sensor. Background technique [0002] At present, in the electronic product market, most devices have automatic brightness adjustment functions, which are realized by light sensors. However, because multiple devices of the same model were not calibrated under the same lighting environment in advance, multiple devices of the same model with the automatic brightness adjustment function turned on showed different backlight brightness under the same lighting environment. However, if a user owns these devices at the same time, they will doubt the quality of the device due to the difference in backlight brightness, which greatly affects the user experience.

Problems solved by technology

However, because multiple devices of the same model were not calibrated under the same lighting environment in advance, multiple devices of the same model with the automatic brightness adjustment function turned on showed different backlight brightness in the same lighting environment.

However, if a user owns these devices at the same time, he will have doubts about the quality of the device due to the difference in backlight brightness, which will greatly affect the user experience.

[0003] In the prior art, in order to solve the problem that the same type of equipment may display different backlight brightness under the same lighting environment, the usual method is to slowly increase or decrease the backlight brightness so that users can adapt to the backlight brightness, but still Unable to fundamentally solve the problem of differences between different devices
