Abstract:
1. A method of filming a high dynamic range video, applied for an electronic product having an image sensor, and the method comprising the following steps: using the image sensor to capture an original image which is interlaced by a plurality of long exposure areas and a plurality of short exposure areas, and the original image comprising a plurality of pixels; forming the plurality of long exposure areas as a long exposure field, and forming the plurality of short exposure areas as a short exposure field; forming a reconstructed long exposure field and a reconstructed short exposure field having the same resolution as the original image based on a pixel value of each pixel of the long exposure field and the short exposure field via a reconstruction process; and applying the pixel value of each pixel of the reconstructed long exposure field and the reconstructed short exposure field to form a high dynamic range image via a merging process; wherein the pixel value is an integer within 0 to 2x−1 and x is a number of digits of the image sensor, different pixel values correspond to different levels of illuminance, and a ratio of a long exposure duration of the plurality of long exposure area to a short exposure duration of the plurality of short exposure area is a exposure duration ratio (R), and wherein the reconstruction process and the merging process comprise performing the following steps on each pixel of missing parts of the plurality of the long exposure areas:
