Title:
METHOD AND APPARATUS FOR ELIMINATING FLICKER DURING PHOTOGRAPHING, PHOTOGRAPHING DEVICE, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/208923
Kind Code:
A1
Abstract:
The present application provides a method and an apparatus for eliminating flicker during photographing, a photographing device, and a readable storage medium, an electrochromic neutral density filter being provided in a camera. The method for eliminating flicker during photographing comprises: acquiring a flicker frequency of current ambient light; setting a shutter time of the camera according to the flicker frequency and a preset algorithm; acquiring a current brightness value received by the camera at the shutter time; determining whether the current brightness value is greater than a preset brightness value; and if the current brightness value is greater than the preset brightness value, controlling the transmittance of the electrochromic neutral density filter, so as to decrease the brightness value received by the camera to the preset brightness value. In the present application, after a corresponding shutter time is generated, flickering stripes during photographing can be effectively eliminated, and by controlling the electrochromic neutral density filter, overexposure during photographing caused by using a fixed shutter time in a bright scene can be effectively avoided, thereby improving the photographing experience of users.
