Stereoscopic Preview for Printed Swelling Representation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems fail to accurately represent the swelling portions of printed matter in preview images, lacking the stereoscopic effect that real printed items exhibit due to adhesion of image forming materials like ink or toner.
Innovation Solution
An image processing system that generates stereoscopic image data by predicting film thickness and creating normal maps to display a preview image, incorporating information about the inclination or rounding of the image forming material's edge, simulating the three-dimensional appearance of the printed matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image processing is used to generate preview images, then the processing is simple and fast, but the swelling portion of the printed matter cannot be accurately represented
Solution Approach 1:
The patent transitions from 2D image data to 3D stereoscopic image data by generating normal maps that represent the swelling portion's height information. This dimensional transformation enables accurate representation of the swelling portion's three-dimensional characteristics including inclination and rounding aspects, resolving the contradiction between representation accuracy and processing complexity.
Solution Approach 2:
The system performs preliminary generation of normal maps and stereoscopic image data before actual printing. By pre-calculating the swelling portion characteristics and incorporating them into the preview image, the system achieves accurate representation without adding complexity to the actual printing process.
2Measurement precision
If detailed stereoscopic information is generated to represent the swelling portion accurately, then the preview accuracy improves, but the processing time and computational load increase
Solution Approach 1:
The patent applies local quality by generating normal map information specifically for regions containing swelling portions rather than processing the entire image uniformly. The system identifies areas with image forming material and concentrates computational resources on calculating the stereoscopic characteristics of these specific regions, thereby improving preview accuracy while reducing overall processing time.
3Measurement precision
If conventional preview techniques are used, then the system is simple to operate, but the swelling portion cannot be visualized in a realistic manner
Solution Approach 1:
The patent creates a virtual copy of the swelling portion's three-dimensional characteristics through normal maps and stereoscopic image data. This virtual copy accurately reproduces the inclination and rounding aspects of the actual swelling portion, enabling realistic visualization without requiring physical samples or complex manual measurements, thus maintaining ease of operation while improving realism.

AI summary
An image processing system includes a processor configured to generate stereoscopic image data including information representing a layer thickness of an image forming material adhered to a recording medium based on image data of a printed image and cause a display unit to display a preview image of a printed matter based on the stereoscopic image data, in which the information representing the layer thickness of the image forming material includes information representing an aspect in which an edge of a swelling portion of the image forming material is inclined toward a recording medium surface or an aspect in which the edge of the swelling portion of the image forming material is rounded.
