Abstract
Presented herein are system(s), method(s), and apparatus for providing high resolution frames. In one embodiment, there is a method comprising receiving upscaled frames; motion estimating the upscaled frames; and motion compensating the upscaled frames.
Claims20
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.
6 more elements
A system including circuitry for providing high resolution frames, said circuitry comprising:
- an input for receiving upscaled frames;
- a downsampler for downsampling the upscaled frames to a predetermined lower resolution;
- an upsampler for upsampling the downsampled frames to a predetermined higher resolution;
- a motion estimator for motion estimating the upsampled frames produced by the upsampler;
- and
- a motion compensator for motion compensating the upsampled frames produced by the upsampler, wherein the motion compensator is configured to perform motion-compensated back projection and motion-free back projection.
3 more elements
A system including circuitry for providing high resolution frames, said circuitry comprising:
- an input for receiving frames;
- an upsampler for generating upsampled frames by upsampling the frames to a higher resolution, wherein the higher resolution is an integer factor higher than a resolution of the frames;
- a motion estimator for motion estimating the upsampled frames;
- a motion compensator for motion compensating the upsampled frames, wherein the motion compensator is configured to perform motion-compensated back projection and motion-free back projection;
- and
- a downsampler for downsampling the motion compensated upsampled frames to a predetermined resolution.
