Solution Overview
Problem
Current technologies do not allow for independent operation of color and lightness of a transparent material perception using simple image processing techniques, requiring complex knowledge and methods.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If CG software and dedicated graphics language (OpenGL) are used to model and render transparent materials, then the realism and quality of transparent material perception is improved, but the complexity of operation and knowledge required increases significantly
Solution Approach 1:
The patent uses image processing to create a visual copy or simulation of transparent material effects rather than requiring actual 3D modeling and rendering. By manipulating 2D image components (brightness and color) with deformation maps, the system reproduces the appearance of transparent materials without needing complex CG software or OpenGL knowledge, thus maintaining quality while improving ease of operation
Solution Approach 2:
The patent replaces the mechanical/complex rendering system (CG software with ray calculation and physical calculation) with a simpler image processing approach. Instead of using dedicated graphics languages and 3D modeling tools, the invention uses 2D image manipulation techniques including component separation, deformation maps, and modulation to achieve transparent material perception, substituting a complex system with a more accessible one
2Ease of operation
If simple image processing is used to provide transparent material perception, then the ease of operation is improved, but the ability to independently operate color and lightness is lost
Solution Approach 1:
The patent segments the image into separate brightness components and color components using component separation. This allows independent manipulation of each component through different deformation maps and modulation processes, enabling users to control color and lightness independently while still using simple image processing techniques, thus resolving the contradiction between ease of operation and adaptability
Solution Approach 2:
The patent introduces dynamic control mechanisms where users can independently adjust color and lightness parameters through separate deformation maps and modulation processes. This dynamic capability allows flexible and independent operation of color and lightness properties while maintaining the simplicity of image processing approaches, enhancing adaptability without sacrificing ease of use

AI summary
Using different deformation maps that have elements corresponding to respective pixels deriving from an original image and have low-spatial frequency components, the elements indicating a moving direction and a moving amount of the corresponding pixels, the pixels deriving from the original image are moved in a moving direction by a moving amount, the moving direction and the moving amount being specified by the elements corresponding to the respective pixels, and modulated images are obtained. The modulated images are separated into brightness components and color components to obtain brightness component images and color component images, brightness of brightness component images and/or color of color component images is modulated to obtain brightness-modulated image and/or color-modulated image, and a video is obtained, the video being configured by arranging integrated images obtained by integrating the obtained brightness-modulated images and/or color-modulated images.
