Abstract
In embodiments, a camera device includes HDR monochromatic image sensors that capture an image as an HDR clear image in monochrome, and the camera device includes HDR color image sensors that capture the image as a Bayer image. The HDR monochromatic image sensors may be implemented as interlaced pixel lines having alternating higher exposure times and lower exposure times, or may be implemented as a checkerboard pixel pattern with white pixels of the checkerboard pixel pattern having an exposure duration and black pixels of the checkerboard pixel pattern having a different exposure duration. The camera device implements image processing algorithms that demosaic the Bayer image to generate an initial color image, and demosaic the HDR clear image to generate a clear image. An image fusion application then produces an enhanced, high-resolution HDR color image based on the initial color image and the clear image.
