  • Method for generating an HDR image of a scene based on a tradeoff between brightness distribution and motion
    Patent number: 9648251
    Abstract: The present invention relates in general to a method of high dynamic range (HDR) digital imaging and determining and setting exposure parameters for detection of image data by an imaging device, such as a digital camera, to produce a high dynamic range (HDR) image of a scene. The method includes setting an exposure (Ei+1) for a next frame (fi+1) as a function of the current exposure (Ei), of a first brightness distribution (Hfulli) of colors of pixels of the current frame (fi) and of a second brightness distribution (Hmotioni) of colors of those pixels weighted by the motion of those pixels, such that motion is evaluated for those pixels in comparison with a previous frame (fi), capturing the next frame (fi+1) under the set exposure (Ei+1) and merging the next frame (fi+1) with at least the current frame (fi) into an HDR image.
