Patent ID: 7688387

Claim:
A method of processing an original video signal, wherein a sample of interest is B3, comprising: (a) receiving a sampled video signal; (b) identifying a sample of interest on a current line of the sampled video signal; (c) comparing, with a decision logic device, values from a current line of the sampled video signal with values of a previous line of the sampled video signal and with values of a subsequent line of the sampled video signal, wherein at least a portion of the values represent the sampled video signal between original samples and wherein comparing comprises: (i) obtaining a value B2 from the current line of the sampled video signal at ¼ period prior to the sample of interest B3; (ii) obtaining a value B4 from the current line of the sampled video signal at ¼ period after the sample of interest B3; (iii) obtaining values A2, A3, and A4 from the previous line of the sampled video signal, whereby the values A2, A3, and A4 correspond horizontally to the values B2, B3, and B4, respectively; (iv) obtaining values C2, C3, and C4 from the subsequent line of the sampled video signal, whereby the values C2, C3, and C4 correspond horizontally to the values B2, B3, and B4, respectively; (v) determining a difference between the values B2 and A4, and between the values B4 and A2; (vi) determining a difference between the values B2 and C4, and B4 and C2; and (vii) determining a difference between the values B3 and A3, and between the values B3 and C3; (d) applying, with a blending device, weights to outputs of a plurality of video processing procedures for the sample of interest based on the comparison of step (c); and (e) outputting a processed signal from the blending device, wherein the processed signal comprises a combination of a portion of the outputs from each of the plurality of video processing procedures according to the applied weights.
