Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to accurately display the texture of materials as their appearance changes with variations in the observation environment or orientation, whether in paper or electronic media.
Innovation Solution
An image processing device and method that renders display data based on illumination information, material texture characteristics, and the relative positional relationship of light sources, display surfaces, and viewers, incorporating sensors and communication means to detect and adjust for ambient and external illumination, orientation, and viewer direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional picture or illustration methods are used to display material texture, then the display is simple and static, but the texture appearance cannot change according to observation environment or material orientation
Solution Approach 1:
The patent applies dynamics by making the displayed texture image change dynamically according to the observed direction and illumination conditions. The rendering unit generates different texture images based on the relationship between light source, display surface, and viewer position, allowing the texture appearance to adapt to different observation environments rather than displaying a static image.
Solution Approach 2:
The patent changes the parameters of the displayed image based on illumination information and relative positional relationships. By adjusting rendering parameters according to light source position, viewer angle, and material properties, the system generates texture images that accurately reflect how the material would appear under different conditions.
2Measurement precision
If physical sample collections are used to display material texture, then the texture can be perceived accurately, but the method is cumbersome and requires physical storage space
Solution Approach 1:
The patent creates virtual copies of physical material textures through rendering. Instead of requiring physical sample pieces, the system generates digital texture images that simulate the appearance of real materials under various lighting and viewing conditions, providing an accurate yet convenient alternative to physical samples.
Solution Approach 2:
The patent replaces the mechanical system of physical sample handling with a computational rendering system. By substituting physical material samples with algorithmically generated images based on illumination and geometric parameters, the system eliminates the need for physical storage and handling while maintaining texture perception accuracy.
3Adaptability or versatility
If multiple original images are captured from different illumination positions to display texture, then the texture can be viewed from different angles, but the system requires multiple images and sequential switching
Solution Approach 1:
The patent performs preliminary action by pre-calculating and storing texture images for multiple illumination and viewing conditions. The rendering unit can generate the appropriate texture image directly based on the current light source and viewer positions without requiring sequential switching between pre-captured images, reducing time delay.
Solution Approach 2:
The system uses feedback from illumination information and relative positional relationship data to dynamically select or generate the appropriate texture image. By continuously monitoring the lighting conditions and viewer position, the rendering unit adjusts the displayed texture in real-time, providing seamless adaptation without manual switching.
