An improved deinterlacing technique is provided. In one embodiment, a method for deinterlacing includes receiving an interlaced frame of data, the frame including a primary field and a secondary field, and deinterlacing the frame, the deinterlacing including computing an output pixel, PIXOUT, of the secondary field based on an input pixel, PIXIN, of the secondary field, a bottom pixel, BOTTOM, of the primary field, and a top pixel, TOP, of the primary field, in which PIXOUT is computed according to an input/output curve that converges to an average of BOTTOM and TOP. The deinterlacing technique in accordance with this embodiment minimizes spatial artifacts and efficiently generates each output pixel value from only three input pixels.
