Abstract
Aspects of the disclosure provide an ambient brightness detection method, an electronic device, a detection apparatus, and a storage medium. The method can be applied to an electronic device including a display array and a light sensing component that is arranged on a back of the display array. The method can include that a detected brightness is obtained through the light sensing component in a display time slot of a target pixel portion covered by a projection in a plane where the display array is located, and a brightness scene is determined according to present display brightness of the display array. The method can also include that a calculation parameter for calculation of ambient brightness is determined according to the brightness scene, a display refresh rate of the display array, and the detected brightness, and the ambient brightness is determined according to the calculation parameter.
