  • Patent number: 10448047
    Abstract: An encoder circuit includes a reduction circuit, a statistical processing circuit, a first motion search circuit, and a second motion search circuit. The reduction circuit generates reduced images of multiple patterns with respect to each of macroblocks. Each of frame images included in video is divided into the macroblocks. The statistical processing circuit performs statistical processing on motion vectors detected with respect to each of the macroblocks. The first motion search circuit selects one of the reduced images generated with respect to the frame image of a reference frame, based on the result of the statistical processing, and searches a first search range in the selected one of the reduced images so as to detect a first motion vector. The second motion search circuit searches a second search range set in the reference frame based on the first motion vector so as to detect a second motion vector.

  • Patent number: 10404924
    Abstract: Techniques are disclosed for detecting stationary presence using IR sensor data. A number of IR images may be captured based on IR sensor data and these IR images may be averaged over various time intervals to calculate a number of average IR frames. The difference between these average IR frames provides a delta frame. A mask frame may be calculated as the summation of delta frames over time, and the value of the mask frame may be used to detect a stationary human presence even when no delta value is calculated. Alternatively, the mask frame may be used to calculate a background frame that represents the IR signature of stationary or cyclical objects within the scanned area that are not intended to trigger the presence detection system. A stationary presence may be determined by subtracting the background frame from a current average IR frame.

  • Patent number: 10362329
    Abstract: Techniques described use a reference motion vector to reduce the amount of bits needed to encode motion vectors for inter prediction. One method includes determining a reference motion vector used to encode a current block of a current frame. The reference motion vector was selected by identifying, multiple candidate motion vectors used to inter predict blocks, and identifying a set of reconstructed pixel values from at least one block adjacent to the current block. For each candidate motion vector, a set of predicted pixel values for the set of reconstructed pixel value is generated using the candidate motion vector and a first reference frame, and an error value is calculated based on a difference between the sets of pixel values. Finally, a reference motion vector from the candidates is selected based on the error values. The method also includes decoding the current block using the reference motion vector.
