Patent ID: 8264615

Claim:
A system comprising: a detail edge enhancer that comprises a first filter, a first noise reducer, a first gain multiplier, a second filter, a second noise reducer, a second gain multiplier and a first adder, wherein: (i) the detail edge enhancer is configured to receive a video signal that includes a plurality of fine detail edges, (ii) the first filter, first noise reducer, and the first gain multiplier are configured to enhance the plurality of fine detail edges of the received video signal horizontally to create a horizontal output signal, wherein the first noise reducer is configured to subtract a noise threshold from a noise level of the received video signal, (iii) the second filter, second noise reducer, and the second gain multiplier are configured to enhance the plurality of fine detail edges of the received video signal vertically to create a vertical output signal, and (iv) the first adder is configured to combine the horizontal output signal and the vertical output signal to generate a combined output signal; an edge map generator that comprises a pixel differentiator, an expander, and a threshold generator, wherein the pixel differentiator, the expander, and the threshold generator are configured to create an edge map of the received video signal; a second adder configured to combine the combined output signal with the edge map to generate a detail enhanced video signal; a first scaler configured to scale the detail enhanced video signal; and a transition enhancer configured to apply transition improvement to a plurality of transitions in the scaled video signal.
