Abstract:
1. A de-interlacing method using remote interpolation, comprising: a plurality of pixels above a new pixel to be interpolated constituting an up window, and a plurality of pixels below the new pixel constituting a down window; using the pixels along a vertical direction with respect to horizontal to interpolate the new pixel when values of the pixels are closest to each other, followed by moving the up window and the down window respectively one step to the right, wherein the step is distance between two neighboring pixels on a horizontal line; using the pixels along a direction that is at a negative angle with respect to horizontal to interpolate the new pixel when values of the pixels are closest to each other, followed by moving the down window at least two steps to the right while staying the up window; and using the pixels along a direction that is at a positive angle with respect to horizontal to interpolate the new pixel when values of the pixels are closest to each other, followed by moving the up window at least two steps to the right while staying the down window.
