Engineering Contradiction Analysis
1Measurement precision
If sophisticated graphics are used in computer simulations, then visual quality is improved, but memory space and processing time requirements increase
Solution Approach 1:
The patent segments the color image into multiple grayscale images (e.g., two grayscale images combined with four colors). This segmentation allows the system to store and process multiple simpler grayscale images instead of a single complex color image, reducing overall memory requirements while maintaining visual quality through the combination of grayscale images and color channels.
Solution Approach 2:
The patent changes the parameter representation from storing full color images to storing grayscale images with associated color parameters. By using gradient descent to optimize the combination of grayscale images and colors, the system achieves efficient memory usage while preserving visual fidelity through parameter optimization.
2Measurement precision
If sophisticated graphics are used in computer simulations, then visual quality is improved, but processing time increases
Solution Approach 1:
The patent applies gradient descent in advance to pre-optimize the combination of grayscale images and color parameters before rendering. This preliminary optimization step creates pre-computed shader masks and parameters that can be efficiently applied during runtime, reducing processing time during actual simulation while maintaining high visual quality.
Solution Approach 2:
The patent replaces traditional mechanical shading operations with a machine learning-based approach using gradient descent. By substituting complex real-time shading calculations with pre-computed neural network outputs and optimized parameter combinations, the system reduces processing time while maintaining or improving visual quality.
3Quantity of substance
If gradient descent is used to optimize image rendering, then memory requirements are reduced, but computational complexity increases
Solution Approach 1:
The patent uses grayscale images as simplified copies or representations of the original color image information. By working with multiple grayscale images instead of full color data during the gradient descent optimization, the system reduces memory requirements and computational complexity while still being able to reconstruct the full color image through the combination of grayscale images and color parameters.

AI summary
A graphics shader takes in two grayscale images (called “masks”) and four colors and generates a full-color image. The logic behind the shader is two-fold. First, separating the colors from the image enables a greater variety of images (for example, change one color to get different colored brick walls), and secondly, two grayscale masks take up less space in memory than a full-color image. A script that uses differentiable programming and gradient descent “finds” the masks and colors for a target image.
