Circuitry and techniques for image processing

摘要

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.

1. A method of interpolating an image field with image processing circuitry, the method comprising:
with the image processing circuitry, identifying a pixel to be interpolated from a first row of the image field; with the image processing circuitry, determining a plurality of edge direction vectors from the identified pixel and a plurality of neighboring pixels in a second row of the image field; with the image processing circuitry, combining the plurality of edge direction vectors to produce an interpolated pixel; and assigning a score to each pixel of the plurality of neighboring pixels in the second row based on an angle of a corresponding edge direction vector of that pixel with respect to a horizontal axis of the image field.
