Abstract
A method for interpolating an image field with image processing circuitry includes identifying, from a first row in the image field, a pixel to be interpolated. Edge direction vectors from the identified pixel and a plurality of neighboring pixels in a second row of the image field are determined. The edge direction vectors may then be combined to produce an interpolated pixel. The edge direction vectors may be combined such that the pixel is interpolated along each edge direction vector to obtain multiple interpolated pixel values. The pixel may be interpolated based on a weighted average of the interpolated pixel values.
