Patent ID: 8228429

Claim:
A method comprising: using an edge gradient to select a best interpolation direction for several adjacent pixels between two lines of pixels in interlaced video; performing an interpolation of an intermediate line between said lines of pixels using said best interpolation direction; analyzing the pixels in the lines above and below each interpolated pixel to reduce artifacts; determining if the interpolated pixel is less than or equal to the maximum intensity of the pixels above and below the interpolated pixel plus a threshold; determining whether the interpolated pixel is greater than or equal to the minimum of the intensity of the pixels above and below the interpolated pixel minus the threshold; and wherein if the interpolated pixel intensity is less than or equal to the maximum and greater than or equal to the minimum, outputting the value of the interpolated pixel and, otherwise, outputting the average intensity of the pixels above and below the interpolated pixel as the intensity value for the interpolated pixel.
