Neural Supersampling via Jittered Sub-Pixel Sampling and Motion Compensation

The patent divides each low-resolution pixel into multiple sub-pixels and performs jittered sampling on these sub-pixels. This segmentation allows the system to achieve high-resolution output by processing smaller, more manageable units (sub-pixels) independently, thereby improving image quality while distributing the computational load across multiple smaller operations rather than a single complex operation.

The patent transitions from sampling at the pixel level to sampling at the sub-pixel level, effectively adding a dimensional level of detail. By operating on sub-pixels rather than entire pixels, the system achieves supersampling without requiring a proportional increase in overall computational complexity, as the sub-pixel operations can be parallelized and optimized.

The patent performs motion compensation using motion vector maps that are generated in advance or updated efficiently. By preparing the motion vector data beforehand or using predictive models, the system reduces the real-time computational burden while maintaining accurate motion compensation, thus improving motion accuracy without proportionally increasing processing time.

The patent employs dynamic motion vector maps that adapt to changing scene conditions. Rather than using static pre-computed maps, the system dynamically adjusts motion vectors based on current frame differences and scene complexity, allowing efficient motion compensation that scales with actual processing needs rather than fixed time constraints.

The patent implements a feedback mechanism where the change in sampling positions is detected and used to adjust pixel shifting operations. By monitoring the sampling position changes and feeding this information back into the pixel shifting process, the system maintains high sampling accuracy while using simple, straightforward shifting operations rather than complex re-sampling algorithms.

The patent replaces complex mechanical sampling adjustment systems with simpler pixel shifting operations. Instead of physically adjusting sampling positions through complex mechanisms, the system achieves sampling accuracy by shifting existing pixels according to calculated offsets, substituting a simple arithmetic operation for a more complex spatial transformation.

The patent merges neural network-based processing with traditional supersampling techniques, combining the strengths of both approaches. By integrating neural networks into the existing supersampling pipeline rather than replacing it entirely, the system achieves improved rendering quality while leveraging the efficiency of traditional methods, thus reducing the overall computational resource requirement compared to using neural networks alone.

The patent optimizes neural network parameters and processing thresholds to achieve high rendering quality with reduced computational resources. By carefully tuning parameters such as network depth, activation functions, and processing thresholds, the system maintains excellent rendering quality while minimizing unnecessary computational operations, thereby reducing energy consumption and resource requirements.
