Abstract: The present invention discloses a method of filming a high dynamic range video. The method includes: using an image sensor to capture an original frame which is interlaced by a plurality of long exposure areas and a plurality of short exposure areas; forming a long exposure field via a plurality of long exposure areas and forming a short exposure field via a plurality of short exposure areas; forming a reconstructed long exposure field and a reconstructed short exposure field having the same resolution as the original frame via a reconstruction process by a pixel value of each pixel in the long exposure field and the short exposure field; and forming a high dynamic range image based on the pixel value of each pixel of the reconstructed long exposure field and the reconstructed short exposure field via a merging process.

Abstract: A method for controlling an exposure duration of a high dynamic range image, including: consecutively generating a first high dynamic range image having a first exposure duration ratio and a second high dynamic range image having a second exposure duration ratio greater than the first exposure duration ratio; performing image quality evaluations on both the first high dynamic range image and the second high dynamic range image to obtain a first image quality and a second image quality, respectively; and determining whether the second image quality is better than the first image quality; if yes, generating a third high dynamic range image having a third exposure duration ratio greater than the second exposure duration ratio; if not, generating the third high dynamic range image having the first exposure duration ratio and setting the first exposure duration ration as the optimal exposure duration ratio.
