摘要： A video sequence may include a modality corresponding with an embedded pattern. At least one state machine detects the modality in accordance with difference signals. A signal generator generates the difference signals responsive to decision windows that define regions of interest in the video sequence. The modality may correspond with an embedded film source or other pattern types in the video sequence. Where the state machine detects more than one pattern, a single pattern is selected according to a predetermined priority. The video sequence may contain both static patterns and embedded film source patterns. The state machine discerns the presence of the embedded film source patterns notwithstanding the presence of the static patterns.

摘要： A method for interpolating a target pixel from a plurality of source pixels in a high contrast image. The method comprises the following steps. A window of the plurality of source pixels is examined and compared with a plurality of predefined conditions for determining if a structure of significance is present within the window. A filter configuration is selected from a plurality of filter configurations in accordance with results of the comparison. The selected filter is applied to the source pixels for interpolating the target pixel. If the structure of significance is detected in the window, the selected filter best preserves the structure.

摘要： Contrast in an image is enhanced by mapping an input intensity value to an output intensity value in accordance with a mapping function. A mean intensity value of the image is determined. Co-ordinates of the mapping function are calculated in accordance with the mean intensity value and a plurality of predefined parameters. The mapping function is applied to the input intensity value for determining the output intensity, wherein the mapping function is generated dynamically for each image.

摘要： Motion vectors are determined from two images by obtaining one or more candidate motion vectors from the two images. Regions of the two images associated with the candidate motion vector are modified. Thereafter, further candidate motion vectors are obtained from the modified images, reducing the interfering effect of regions for which motion vectors have already been determined.

The system comprises a signal generator for generating a plurality of signals. The signals are generated in accordance with pixels input from the video sequence. The system further comprises a plurality of pattern detection state machines, each for receiving the signals and for detecting a pattern in the video sequence. The pattern is detected in accordance with a preset threshold, wherein the pattern detection state machine varies the preset threshold in accordance with the received signals. The system further comprises an arbiter state machine coupled with the plurality of pattern detection state machines for governing the pattern detection state machines and for determining whether or not a non-video source is embedded in the video sequence.

摘要： A system and method are provided for calculating a target pixel for scaling an image comprising a plurality of source pixels. A contour is determined in the image using at least one of a first set of predetermined parameters. A filter tap configuration is adaptively selected from a predefined set of filter tap configurations in accordance with the determined contour. The predefined set of configurations includes a plurality of non-linear filter tap configurations. The target pixel is calculated by selectively convolving ones of the plurality of source pixels along a locus of the selected filter tap configuration with a weighting factor, and combining the convolved pixels.
