  • Patent number: 11849244
    Abstract: A system is provided for capturing a key signal within video frames that includes a camera that captures a sequence of media content of a live scene that includes an electronic display having a higher frame rate than an output frame rate of the camera, and a key signal processor that convert all frames in the sequence of media content to the output frame rate of the camera, analyzes a sequence of frames to determine the key signal based on the electronic display outputting a sequence of frames including media content and at least one key frame included in the sequence, and combine remaining frames of the sequence of frames to create a live output signal. Moreover, the key signal processor determines, for each pixel in the frames, whether the pixel has a set chromaticity, and generates a key mask for each pixel in each frame.

  • Publication number: 20160381344
    Abstract: A camera includes a lens configured to receive an optical image from two viewing angles. A filter converts the optical image into two orthogonally polarized images, each orthogonally polarized image corresponding to a different one of the viewing angles. An image detector distinguishably detects the two orthogonally polarized images in a single frame. An image processor decodes the two orthogonally polarized images in the single frame into two video signals corresponding to the two viewing angles.

  • Patent number: 9338435
    Abstract: A camera includes a single lens configured to receive an optical image as two images from two viewing angles. The two images from respective viewing angles are converted into two orthogonally modulated images, each of the orthogonally modulated images corresponding to a different one of the two viewing angles. An image detector is configured to distinguishably detect the two orthogonally modulated images in a single frame. An image processor is configured to decode the two orthogonally modulated images in the single frame into two video signals corresponding to the two viewing angles.

  • Patent number: 9188663
    Abstract: An improved solution for generating depth maps using time-of-flight measurements is described, more specifically a time-of-flight imager and a time-of-flight imaging method with an improved accuracy. A depth correction profile is applied to the measured depth maps, which takes into account propagation delays within an array of pixels of a sensor of the time-of-flight imager.
