Printed Layer Rendering for Realistic Front and Back Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies struggle to accurately reproduce the appearance of printed objects using transparent, translucent, or opaque print media without a feeling of incongruity when viewed from different angles.
Innovation Solution
An image processing device that includes an image data acquisition section, a printing condition acquisition section, a color conversion section, and a rendering section, which calculates a shielding degree for printed layers on transparent or translucent media to generate both front and back surface views of the printed object, allowing for accurate rendering of the object's appearance from different perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional rendering methods are used for transparent or translucent print media, then the rendering process is simple, but the reproduced appearance lacks realism and creates a feeling of incongruity when viewed from different angles
Solution Approach 1:
The patent segments the printed object into multiple layers (front surface printed layer, back surface printed layer, and transparent/translucent base layer) and processes each layer separately with appropriate rendering techniques. This allows complex light interaction effects to be achieved by combining simpler individual layer renderings, resolving the contradiction between accuracy and complexity.
Solution Approach 2:
The patent applies different rendering qualities and methods to different regions of the printed object. The front and back surface printed layers receive different processing than the transparent/translucent base layer, with each region rendered according to its specific optical properties. This localized approach achieves realistic appearance without uniformly increasing overall complexity.
2Measurement precision
If shielding degree calculation is performed for each printed layer, then the appearance from different angles is accurately reproduced, but the computational complexity increases
Solution Approach 1:
The patent calculates shielding degree selectively for the front surface and back surface printed layers rather than for the entire printed object uniformly. This partial application of complex calculation only where optically necessary achieves accurate light interaction simulation without excessively increasing computational power requirements across the whole system.

Function Achieved in This Case
The solution enables the generation of realistic and coherent front and back surface views of printed objects, enhancing the perception of printed objects using transparent, translucent, or opaque media by accurately simulating light interaction with the print medium layers.

AI summary
An image processing device includes a shielding degree calculation section that calculates a shielding degree of a printed layer, and a rendering section. The rendering section is configured to generate at least one of the front surface view, in which the printed object is observed from the front surface side, and the back surface view, in which the printed object is observed from the back surface side, by mapping an image data, which is color converted, to a 3D object and by performing rendering using the shielding degree of the printed layer.
