More Information
Summary:Provided is a method for generating an HDR image by: obtaining a plurality of images photographed at different exposure levels; generating at least one transformation matrix indicating a corresponding area between the plurality of images; determining a motion level for each corresponding area between the plurality of images based on the transformation matrix; generating a blending map indicating a blending ratio of the plurality of images in each pixel based on the determined motion level; and blending the plurality of images based on the blending map. 서로 다른 노출 정도로 촬영된 복수 개의 영상들을 획득하고, 복수 개의 영상들 간 대응되는 영역을 나타내는 적어도 하나의 변환 행렬을 생성하고, 변환 행렬에 기초하여, 복수 개의 영상들 간 대응되는 영역별로, 움직임 정도를 결정하고, 결정된 움직임 정도에 기초하여, 각 픽셀에서, 복수 개의 영상의 블렌딩 비율을 나타내는 블렌딩 맵을 생성하고, 블렌딩 맵에 기초하여, 복수 개의 영상을 블렌딩함으로써, HDR 영상을 생성하는 방법이 제공된다.
