  • Patent number: 10755673
    Abstract: The disclosure features information display systems that include a display device, at least one sensor, and an electronic processor connected to the display device and to the at least one sensor. During operation of the system, for a set of pixels of the display device that are used to display visual information, the electronic processor is configured to determine a range of target luminance values for a subset of the pixels for which a Weber contrast value is less than the contrast threshold value, adjust luminance values for the set of pixels so that at least some members of the subset of pixels have Weber contrast values, based on their adjusted luminance values, that exceed the contrast threshold value, and display the visual information on the display device using the members of the set of pixels with the adjusted pixel luminance values.

  • Patent number: 10397539
    Abstract: The disclosure features three-dimensional stereoscopic imaging systems and methods that include two image capture devices configured to obtain images of a scene, at least one display screen, and an electronic processor configured to: receive one or more images of the scene from the capture devices, where each of the one or more images includes a lateral dimension and a height; warp the one or more images along their respective lateral dimensions to at least partially correct for disparity distortions associated with displaying the one or more images on the at least one display screen; correct the one or more images by scaling the respective heights of the images along the lateral dimensions of the images so that the height of each image is the same along the images lateral dimension; and display the warped and corrected one or more images on the at least one display screen.
