Patent ID: 6975359

Claim:
A system for edge-adaptive frame rate up-conversion, comprising: a capture block for receiving and processing an input signal; a frame buffer to receive and process a data signal output from said capture block; an edge-adaptive interpolator to generate an interpolated field signal from a set of current input field signals output from said frame buffer; a motion detector to receive a composite signal output from said frame buffer and process said composite signal to generate a motion signal; a blender to receive a prior input field signal from said frame buffer, said interpolated field signal from said edge-adaptive interpolator, and said motion signal and generate an edge and motion-interpolated field signal; a synchronization control block to process an input vertical synchronization signal received from said capture block and generate an output synchronization signal and an output field parity signal; a comparator to receive and compare said output field parity signal and an input field parity signal output from said capture block; and a multiplexer to select, based on the output of said comparator, and provide as an up-converted output signal, either one of the set of said current input field signals output from said frame buffer or said edge and motion-interpolated field signal; wherein said set of current input field signals comprises a first current input field signal and a second current input field signal, each comprising pixel data for a corresponding first and second input field display lines; and wherein said edge-adaptive interpolator is operable to perform edge-adaptive interpolation to generate said interpolated field signal from said first and second current input field signals, and wherein said interpolated field signal comprises pixel data for a corresponding interpolated field display line.
