AI Technical Summary

Technical Problem

As the screen-to-body ratio of electronic devices increases, the visible light transmittance of the display screen decreases, affecting the use of the under-screen ambient light sensor and leading to inaccurate acquisition of ambient light parameters.

Method used

When the screen is detected to be on but no shooting operation is detected, the camera module is configured to switch to low power mode. The camera module then captures the current image and obtains the ambient light parameters in low power mode.

Benefits of technology

It improves the accuracy of ambient light parameters and reduces the power consumption of the camera module.

Abstract

The present disclosure provides an ambient light parameter acquisition method and device, an electronic device and a storage medium. The method comprises: when it is detected that a display screen of the electronic device is in a bright screen state and a shooting operation is not detected, configuring a camera module of the electronic device to switch to a low-power mode; acquiring a current image collected by the camera module in the low-power mode; and acquiring an ambient light parameter of an environment in which the electronic device is located according to the current image. The present embodiment can acquire the ambient light parameter of the environment in which the electronic device is located by using the current image acquired by the camera module, and can avoid the influence of the display screen on the under-screen ambient light sensor when the visible light transmittance is low, thereby improving the accuracy of acquiring the ambient light parameter. Furthermore, in the present embodiment, the camera module can be switched to the low-power mode to acquire the current image, thereby reducing the power consumption of the camera module.
