Abstract
The invention discloses a method for quickly adjusting white balance of a camera, which comprises the steps of acquiring color temperature information of the current environment of a mobile terminal in real time through a color temperature sensor, and acquiring corresponding white balance parameters according to the color temperature information; then loading the white balance parameters when the camera function of the mobile terminal is started; and then adjusting the imaging effect of the camera based on the white balance parameter. The invention also discloses a device for quickly adjusting the white balance of the camera and a computer readable storage medium. The method acquires the color temperature information of the current environment before entering the camera picture of the terminal, effectively shortens the adjustment time of automatic white balance after entering the camera picture, improves the user experience, and can acquire the color temperature information through the color temperature sensor, thereby reducing the power consumption of the mobile phone.
