Abstract: A camera device includes monochromatic and color image sensors that capture an image as a clear image in monochrome and as a Bayer image. The camera device implements image processing algorithms to produce an enhanced, high-resolution HDR color image. The Bayer image is demosaiced to generate an initial color image, and a disparity map is generated to establish correspondence between pixels of the initial color image and clear image. A mapped color image is generated to map the initial color image onto the clear image. A denoised clear image is applied as a guide image of a guided filter that filters the mapped color image to generate a filtered color image. The filtered color image and the denoised clear image are then fused to produce an enhanced, high-resolution HDR color image, and the disparity map and the mapped color image are updated based on the enhanced, high-resolution HDR color image.

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.
