1. A method for providing high resolution frames, said method comprising: receiving frames; determining whether the frames correspond to upscaled frames, the determination further comprising at least one of: estimating a kernel used in a spatial interpolation to upscale the frames, or estimating at least one of a scaling ratio or a scaling offset used in a spatial interpolation to upscale the frames; and in response to determining that the frames correspond to upscaled frames: motion estimating the upscaled frames; and motion compensating the upscaled frames, the motion compensation comprising: motion-compensated back projection or motion-free back projection.
