Abstract
The present invention provides a high dynamic range video shooting method, comprising: acquiring corresponding images by means of shooting lenses of a multi-lens panoramic camera; determining corresponding image synthesis weights of image pixel blocks according to pixel color gray scale variations, pixel color gray scale differences and pixel color gray scale offsets of the image pixel blocks of each shot image; forming a high dynamic range panoramic shot image based on the image synthesis weights of the image pixel blocks of each shot image; and splicing all the high dynamic range panoramic shot images.
