Ray Tracing Video Rendering via Region Segmentation and Synthesis

The patent divides the image into multiple regions with different rendering priorities. High-priority regions (containing important visual information) are rendered with high quality using ray tracing, while low-priority regions are rendered with lower quality using non-ray tracing methods. This segmentation allows the system to achieve overall high image quality while significantly reducing total processing time by not applying computationally expensive ray tracing uniformly across the entire image.

The patent applies different rendering qualities to different spatial locations within the image. Instead of uniform high-quality ray tracing everywhere, the system concentrates computational resources on specific local regions that contribute most to perceived image quality, while using faster rendering methods in other areas. This local quality approach resolves the contradiction by making image quality high where it matters most while maintaining acceptable quality elsewhere, thereby reducing overall processing time.

The patent dynamically adjusts the rendering method and quality level based on frame-specific conditions such as scene complexity, motion magnitude, and region importance. Rather than statically applying ray tracing to all frames, the system makes dynamic decisions about which frames and regions require high-quality rendering, allowing it to maintain high image quality when necessary while achieving high rendering speeds when possible, thus resolving the contradiction between quality and productivity.

The patent applies ray tracing selectively to only the necessary portions of frames rather than universally. By identifying and rendering only the critical regions that require high quality (partial action), the system achieves acceptable overall image quality while dramatically reducing the computational burden and increasing rendering speed, thereby resolving the contradiction between maintaining image quality and achieving practical rendering speeds.

The patent applies high-ray-count ray tracing only to specific local regions where accurate light simulation is critical (such as regions with complex lighting effects, reflections, or refractions), while using lower-ray-count or non-ray-tracing methods in regions where simple lighting suffices. This localized approach to high precision rendering maintains light simulation accuracy where needed while significantly reducing the total simulation time across the entire image.

The patent segments the image into regions requiring high-fidelity light simulation and regions where approximate rendering is acceptable. By applying different ray counts to different segments based on their lighting complexity and visual importance, the system achieves accurate light simulation in critical areas while maintaining overall rendering efficiency, thereby resolving the contradiction between measurement precision and time consumption.
