  • Patent number: 10638060
    Abstract: Techniques are provided for color correction of image frames, received from a hybrid RGBIR sensor, using resolution recovery of the red, green, blue (RGB), and infra-red (IR) channels. The color correction is to compensate for IR contamination of the RGB channels. A methodology implementing the techniques according to an embodiment includes a demosaic operation on the RGBIR image frame to generate full resolution red, green, blue, and IR frames. The demosaic operation includes filtering to extract Chroma and Luma components of the RGBIR image to reconstruct the full resolution images. The method also includes calculating an IR weighting factor for the pixels of each of the full resolution RGB frames, and correcting for IR contamination of those pixels by subtracting a scaled value of the corresponding pixels from the full resolution IR frame. The scaled value is based on the IR weighting factor associated with the pixel to be corrected.

  • Patent number: 9924142
    Abstract: A method for processing a plurality of images of a scene recorded from different vantage points, where the plurality of images includes a color reference image captured by a Bayer type camera and at least one additional image, the method including (a) registering at least a portion of the plurality of images, and (b) generating a unitary color image from the plurality of images, wherein color information of the unitary color image is determined exclusively from the color reference image.
