摘要： A system including a motion adaptive de-interlacer, a film mode detector, and a combiner. The motion adaptive de-interlacer is configured to determine a first output by de-interlacing a plurality of interlaced frames based on at least a first motion indicator indicating motion between fields of the plurality of interlaced frames. The film mode detector is configured to determine a second output based on a film mode detected based on at least a second motion indicator indicating motion between fields of the plurality of interlaced frames. The film mode detector is further configured to output a control signal based on the second motion indicator and the film mode. The combiner is configured to combine the first output and the second output based on the control signal.

摘要： Efficient editing is enabled when a video material encoded as an interlaced signal is mixed during editing. A first video signal in a progressive mode is obtained. This first video signal is encoded. The first video signal or a second video signal obtained by reducing resolution and/or a frame rate of the first video signal is converted to an interlaced signal from a progressive signal such that a third video signal is obtained. The third video signal is encoded. Encoded data of the first video signal and encoded data of the third video signal are recorded to a recording medium.

摘要： A stereoscopic video processing system includes an output image generator configured to generate interpolation frames in interpolation phases using the frames of the input video signal and the motion vector and output the frames of the input video signal or the interpolation frames as the frames of an output video signal. The stereoscopic video processing system further includes an output controller configured to (i) determine whether frames of the input video signal include image regions with motion based on the motion vector, (ii) control the output image generator to output the interpolation frames upon determining the frames of the input video signal include the image regions with motion, and (iii) control the output image generator to output the frames of the input video signal upon determining the frames of the input video signal does not include image regions with motion.

摘要： To determine if a pixel exhibits artifacts, statistics are generated for the pixel and its neighbors. These statistics are compared with thresholds. If the comparison of the statistics and the thresholds suggests that the pixel exhibits a pixel artifact, then recourse can be taken, either to adjust the pixel value in some way, or to reject the angle of interpolation used in computing the value for the target pixel.

摘要： Integrated circuits with interpolating circuitry for deinterlacing video data are provided. Each frame of video data may include a field of pixels from every-other row of the frame. Edge detection circuitry may generate an edge map for the field. The edge map may be filtered to remove weak edges from the map. Cartesian Hough transformation circuitry may perform Cartesian Hough transforms on the filtered edge map to generate a Cartesian Hough space histogram. The Cartesian Hough space histogram may be filtered to remove bins having insufficient counts. Offset mask generation circuitry may generate an offset mask based on the Cartesian Hough space histogram. Interpolation circuitry may generate interpolated pixel values for missing rows of the field using pixels from the field and the offset mask. The interpolating circuitry may generate deinterlaced video data that is free from image artifacts along low-angle edges using the interpolated pixel values.

摘要： A method and apparatus for generating an interpolated pixel at a vertical position half way between lines in a field of a video frame. The method comprises detecting a degree of motion in the vicinity of said interpolated pixel and providing weighting factors based on said degree of motion, and detecting a degree of variation in the vicinity of said interpolated pixel and providing a further weighting factor based on said degree of variation. The method further comprises calculating a high vertical frequency contribution, calculating a low vertical frequency contribution, calculating a weighted high vertical frequency contribution based on said high vertical frequency contribution and said further weighting factor, calculating a total vertical contribution by summing together said low vertical frequency contribution and said weighted high vertical frequency contribution, calculating a temporal contribution, and calculating said interpolated pixel by summing together weighted contributions from said total vertical contribution and said temporal contribution based on said weighting factors.

摘要： Certain aspects of a method and system for adaptive temporal interpolation filtering for motion compensation may include computing a plurality of weights for adaptively adjusting one or more parameters of a plurality of linear filters utilized for motion compensation. One or more motion compensated output pictures may be generated based on vector median filtering a plurality of linear filtered output pictures generated by the plurality of linear filters. In instances where two frames are utilized for motion estimation of a video sequence, a motion compensated picture of a previous frame and a motion compensated picture of a current frame may be combined to adaptively compute the subsequent weights. In instances where three or more frames are utilized for motion estimation of a video sequence, the generated one or more motion compensated output pictures may be combined with an extracted desired picture from the video sequence to adaptively compute the subsequent weights.
