  • Multi-camera system for implementing digital slow shutter video processing using shared video memory
    Patent number: 7064778
    Abstract: A technique, specifically a method and apparatus that implements the method, that allows a memory to be located remotely from a video source. Specifically, the method provides a write control signal between a video source and a remote memory that allows the remote memory to provide a video image during slow-shutter operation of the camera.

  • Adaptive filter for suppressing repetitive high-frequency information in a video data stream
    Patent number: 6879636
    Abstract: An image comprises pixels, and has repetitive high-frequency information. Decision circuitry identifies the repetitive high-frequency information in at least a subset of the pixels of the image to provide a repetitive-sequence signal. A low-pass filter filters the image to produce low-pass filtered pixels. A switch outputs the pixels of the image as adaptive-filter output, and in response to the repetitive-sequence signal, outputs the low-pass filtered pixels as the adaptive-filter output.
