    Abstract: To enable better encoding of the currently starting to appear high dynamic range images for use in full high dynamic range technical systems (containing an HDR display, and e.g. in an HDR grading application), we invented a method of constructing a code allocation function for allocating pixel colors having pixel luminances to codes encoding such pixel luminances, in which the step of determining the code allocation function to be applied to at least one color coordinate of the pixel to obtain a code value, comprises constructing that function out of at least two partial functions, and similar methods at a receiving side, and apparatuses, and signals for communicating between the two sites. This method allows—in line with applicant's technical approach that HDR images should actually be communicated as a spectrum of differently regraded different dynamic range images of the same scene, e.g.

  • Patent number: 9654700
    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.

  • Patent number: 9491380
    Abstract: A system may include one or more camera modules each containing one or more image sensors. The system may be configured to capture images from light spectra outside the visible band. Therefore, the pixel integration times, and frame rates of the one or more image sensors may be unique and distinct. An image sensor may respond to a trigger control signal by beginning integration of a subset of pixels some duration after an appropriate trigger control signal transitions from low to high. The image sensor may output the frame captured by the pixels a predetermined duration after the trigger control signal transitions, to ensure a deterministic response. Pixels used to generate the image of a subsequent frame may begin integrating during the readout of the current frame. The pixels may be integrated for exactly their programmed integration time, even when the frame rate is varied.
