Abstract
A method and system for edge-adaptive frame rate up-conversion are disclosed. One embodiment of the system of the present invention comprises: a capture block for receiving and processing an input signal; a frame buffer to receive and process a data signal output from the capture block; an edge-adaptive interpolator to generate an interpolated field signal from a set of current input field signals output from the frame buffer; a motion detector to receive a composite signal output from the frame buffer and to process the composite signal to generate a motion signal; a blender to receive a prior input field signal from the frame buffer, the interpolated field signal from the edge-adaptive interpolator, and the motion signal, and generate an edge and motion-interpolated field signal; a synchronization control block to process an input vertical synchronization signal received from the capture block and generate an output synchronization signal and an output field parity signal; a comparator to receive and compare the output field parity signal and an input field parity signal output from the capture block; and a multiplexer to select, based on the output of the comparator, and provide as an up-converted output signal, either one of the set of current input field signals output from the frame buffer or the edge and motion-interpolated field signal. The input signal can comprise a PAL video signal at 50 Hertz. The up-converted output signal can comprise, for example, a 60 Hertz PAL output signal or a 75 Hertz PAL output signal.
