Title:
HIGH DYNAMIC RANGE IMAGE EXPOSURE CONTROL METHOD, AERIAL CAMERA, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/093578
Kind Code:
A1
Abstract:
A high dynamic range image exposure control method, an aerial camera, and an unmanned aerial vehicle. The high-dynamic-range image exposure control method applied to the unmanned aerial vehicle comprises: firstly, obtaining the current frame exposure time duration, the current frame gain, the previous frame exposure time duration, and the previous frame gain of a high dynamic range image; then when the current frame exposure time duration and the previous frame exposure time duration satisfy a preset row number, and/or, when the current frame gain and the previous frame gain satisfy a preset multiple, generating corresponding exposure control information; further, controlling exposure of the high dynamic range image according to the corresponding exposure control information; and finally avoiding the occurrence of an image brightness oscillation phenomenon.
