Document Type and Number:
WIPO Patent Application WO/2023/160178
Kind Code:
A1
Abstract:
The present application relates to the field of photographing. Disclosed are an exposure control method and an electronic device, which solve the problem of an electronic device being unable to intelligently control an exposure parameter according to different scenarios. The specific solution comprises: respectively determining a depth-of-field parameter, a movement level parameter and a noise intensity factor, wherein the depth-of-field parameter is used for representing depth-of-field information of a photographing framing picture, the movement level parameter is used for representing the movement amplitude of a photographed subject or the movement amplitude of an electronic device, and the noise intensity factor is used for representing a noise intensity; determining an exposure parameter according to the depth-of-field parameter, the movement level parameter and the noise intensity factor, wherein the exposure parameter comprises an aperture value, an exposure time value and a photosensibility of a photosensitive sensor; and according to the exposure parameter, controlling an aperture size, a shutter speed and a photosensibility of the electronic device during a photographing preview and/or photographing.
