Denis V. Karch has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11302288
    Abstract: The disclosed techniques use a display device, in conjunction with various optical sensors, e.g., an ambient light sensor or image sensors, to collect information about the ambient lighting conditions in the environment of the display device. Use of this information—and information regarding characteristics of the display device—can provide a more accurate determination of unintended light being added to light driven by the display device. A processor in communication with the display device may evaluate a saturation model based, at least in part, on the received information about the ambient lighting conditions and display device characteristics to determine unintended light. The determined unintended light may prompt adjustments to light driven by the display device, such that the displayed colors remain relatively independent of the current ambient conditions. These adjustments may be made smoothly over time, such that they are imperceptible to the viewer.
