Title:
METHOD OF FAST ESTIMATION OF SCENE BRIGHTNESS AND OPTIMAL CAMERA EXPOSURE
Document Type and Number:
WIPO Patent Application WO/2021/145682
Kind Code:
A1
Abstract:
A method and an apparatus for adjusting an optimal exposure of a camera are provided. The method may include: receiving a camera start command to activate a camera of an electronic device; capturing an image frame of a scene by the camera; obtaining an Exposure Brightness Response (EBR) of the camera; providing the EBR and the image frame as an input to a pre-trained neural network specific to the camera; and determining a plurality of exposure parameters of the camera and a mean pixel brightness (MPB) by using the pre-trained neural network.
