  • Patent number: 9736442
    Abstract: A device, system and method for content-adaptive resolution-enhancement is provided. A plurality of subframe streams are generated from a video stream, each of the plurality of subframe streams comprising a lower resolution version of the video stream, pixel-shifted from one another. A plurality of output subframe streams are generated from the plurality of subframe streams in a one-to-one relationship by: applying a plurality of video enhancement filters to each of the plurality of subframe streams, each of the plurality of video enhancement filters for enhancing different features of the video stream; and, combining one or more resulting enhanced subframe streams into a respective output subframe stream based on data in one or more regions of the video stream. One or more projectors are controlled to project the plurality of output subframe streams to combine the plurality of output subframe streams into a higher resolution projected video stream.

  • Patent number: 9659371
    Abstract: A system and method for online projector-camera calibration from one or more images is provided. The system comprises: a projector, a camera, and a calibration device configured to: determine a map between pixels of each of a projector image and a camera image in fewer than one hundred percent of pixels of the projector image using feature extraction; determine an initial estimate of a fundamental matrix from the map; determine an initial guess of intrinsic properties of the projector and camera using one or more closed-form solutions; iteratively determine an error-function based on the map using the fundamental matrix while adding constraints on the intrinsic properties using the one or more closed-form solutions, and the initial estimate and guess as initial input; and, when the error-function reaches an acceptance value, determine intrinsic and extrinsic properties of the projector and the camera from current values of iterative estimates.
