High dynamic range video recording method and device based on Bayer color filtering array

The invention discloses a high dynamic range video recording method and a device based on Bayer color filtering array. The method comprises steps of performing exposure according to different odd-even double list configuration sensitizing time, obtaining an image frame of different odd-even double list exposure values, decomposing the image frame into an underexposure frame and an overexposure image frame, wherein the underexposure double lists and the deficiency double lists in the underexposure frame are arranged at interval in series and the overexposure double lists and the deficiency double lists are arranged at interval in series in the overexposure image, obtaining underexposure image frame according to the underexposure and the pixel value of the overexposure double-list pixel point and pixel recovery values missing the double list pixel points in the overexposure image frame as the pixel value of the corresponding pixel point on a red-green-blue channel, and merging the overexposure image frame and the underexposure frame according to the pixel value of the pixel point on the red-green-blue channel to obtain a high dynamic range frame according. Through the above steps, the invention can overcome the problem of high speed motion fuzziness and reduce the frame efficiency of high speed continuous shooting.
