  • Patent number: 8780168
    Abstract: DMA transfer of audio and video data. The audio and video data may be received over a serial bus. A DMA engine may provide audio and video data packets to data storage logic based on the audio and video data. The DMA engine may provide each of the audio data packets with a first, same destination address of a first memory and may provide each of the video data packets with a second, same destination address of the first memory. The data storage logic may maintain first and second pointers that indicate a next current memory location for audio data in a first buffer and video data in a second buffer in the first memory, respectively. The data storage logic may receive and store the audio and video data packets at respective locations in the first and second buffers based on current values of the first and second pointers.

  • Publication number: 20130155178
    Abstract: Controlling a camera using a touch interface. A first input control and a second input control may be presented on a touch interface. The first input control may be configured to control pan and tilt of the camera and the second input control may be configured to control zoom of the camera. First user input may be received to the touch display to a first region of one of the input controls. After, second user input may be received to the touch display to a second region outside of the first region. The pan and tilt or the zoom of the camera may be adjusted in response to the second user input.

  • Patent number: 8154632
    Abstract: A system and method for detecting defective pixels in a sensor. A plurality of pixel values of the sensor may be detected. The values may include those of a first pixel and each nearest neighboring pixel to the first pixel. A second pixel may have the highest value of the neighboring pixels. A third pixel may have the next highest value of the neighboring pixels. A first function may be performed on the second pixel value, producing a first output value. A second function may be performed on the third pixel value, producing a second output value. If the first pixel value is higher than the first output value, or, if the first pixel value is higher than the second output value and the second pixel value is higher than the second output value, it may be determined that the first pixel is defective.
