摘要： Methods for reducing optical distortion such as keystone distortion can include receiving an input image and modifying the input image by applying two separate 1D operations to the input image and applying a polyphase filter to the input image, where the first 1D operation is performed after application of the second 1D operation has begun. The modified image can then be projected.

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 of performing motion compensation includes identifying a set of candidate motion vectors for a block in an intermediate frame from a set of motion vectors from a previous and current frames, performing block-level analysis for each candidate motion vector, selecting an interpolation motion vector, and using the interpolation motion vector to interpolate the intermediate frame between the previous and current frames, wherein the number of intermediate frames depends upon a conversion to a faster frame rate. A method of determining background and foreground motion vectors for a block in an interpolated frame includes comparing a first motion vector that points to a previous frame to a second motion vector that points to a next frame to produce a difference, and designating one of the first and second motion vectors as a background motion vector and the other as a foreground motion vector depending upon the difference.

摘要： A method of displaying video data includes receiving, at a timing controller, a frame of pixel data at a resolution lower than the display resolution from an application processor, generating new frames of video data at the timing controller by applying a filter with a different set of coefficients to at least one neighboring frame at the lower resolution to generate a display frame of video data at a higher resolution. A video processing device has an application processor to execute instructions causing the application process to transmit frames of image data at a resolution lower than an original resolution, and a timing controller to execute instructions causing the timing controller to reconstruct frames of image data at the original resolution from the frames of lower resolution.
