Image Processing System for Dynamic Material Texture Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively display the changing texture and appearance of materials in response to environmental changes or orientation, and lack the ability to simulate materials like walls or floors in space, affecting both potential buyers and suppliers of housing.
Innovation Solution
An image processing system that includes a first display for showing a space, a first rendering for adapting the space to applied material, and a second rendering for displaying material texture based on illumination, material characteristics, and viewer position, with optional inclination detection and ambient illumination acquisition to simulate the material's appearance in different environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional picture or illustration displays are used for materials, then the display is simple and easy to implement, but the material texture and appearance changes cannot be effectively expressed
Solution Approach 1:
The patent uses image processing to create visual copies of materials under different illumination conditions and orientations. Multiple images are synthesized to represent how the material would appear in various environments, allowing users to experience texture changes without physical samples
Solution Approach 2:
The system dynamically processes material images by applying different illumination models and orientation transformations. The display adapts to user input by rendering materials in various lighting conditions and angles, creating a dynamic viewing experience from static images
2Adaptability or versatility
If physical sample collections are used to display material textures, then the material texture can be perceived, but the system is cumbersome and not adaptable to different environments
Solution Approach 1:
The patent replaces physical mechanical sample handling with computational image processing. Instead of physically moving samples or changing lighting environments, the system uses software to simulate different illumination conditions and material orientations, achieving environmental adaptability through digital transformation
3Loss of information
If virtual showrooms with CG are used to reproduce house specifications, then the layout can be simulated, but the material texture and appearance changes in response to environmental changes cannot be expressed
Solution Approach 1:
The patent applies specialized image processing techniques specifically to material regions within the virtual showroom. While the overall space rendering uses standard CG methods, the material portions receive enhanced processing that accounts for illumination, orientation, and texture properties, allowing realistic material representation without redesigning the entire rendering system

AI summary
An image processing device includes a display unit and a rendering unit for rendering display data of a material. The rendering unit renders the display data based on illumination information, material information on the texture of the material, and the relative positional relationship of a light fixture, a display surface, and a viewer. The display unit displays an image of the material using the display data. When the material is selected at the image processing device, a virtual space image processing device displays an image of the space to which the selected image is applied based on the illumination information of the space.
