3D Edge Effect on Multi-Page Document
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Physical multi-page documents lack attention-grabbing features on their non-spine edges, which are typically limited to two-dimensional imaging, whereas electronic versions have increased, leading to a decrease in printed publications and a need for physical attributes that draw viewer attention.
Innovation Solution
A technique to create a three-dimensional effect on the edges of multi-page documents by rendering images as stereo pairs and printing the right-eye and left-eye images on opposite edges of the pages, with shorter pages interleaved to maintain visibility, allowing viewers to see the images without adjacent pages covering them, and adjusting image slices to minimize interreflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two-dimensional imaging is used on non-spine edges, then manufacturing simplicity is maintained, but viewer attention and engagement are insufficient
Solution Approach 1:
The patent transforms two-dimensional images into three-dimensional visual effects by printing different portions of a stereo pair image on opposite edges of pages. When viewed together, these edge images create a 3D effect that captures viewer attention while maintaining standard printing processes.
2Shape
If stereo pair images are printed on opposite edges of pages, then three-dimensional effect is achieved, but adjacent pages may cover the printed images
Solution Approach 1:
The patent divides a complete image into a stereo pair consisting of left-eye and right-eye images, then further segments these images across multiple pages. By placing corresponding portions on opposite edges and using shorter pages as spacers, the system ensures each edge image remains visible while collectively forming a 3D effect.
Solution Approach 2:
The patent introduces shorter pages as intermediary elements between pages containing printed edge images. These shorter pages prevent adjacent pages from covering the printed images while maintaining the overall book structure and enabling the 3D effect to be viewed.
3Shape
If image slices are printed on page edges, then three-dimensional effect is created, but interreflection between adjacent pages reduces image quality
Solution Approach 1:
The patent extracts and removes the harmful interreflection effect by adjusting the image slices printed on opposite edges. Through image processing techniques, the system compensates for and eliminates the negative impact of light reflection between adjacent pages, ensuring high-quality 3D image presentation.

AI summary
Methods and systems are provided for a three-dimensional effect on the edge of a multi-page document (e.g., a book). In one embodiment, a first set of image slices associated with a left-eye image is printed on a first side of long pages of a multi-page document. The first set of image slices printed adjacent to edges of the long pages. A second set of image slices associated with a right-eye image is printed on a second side of the long pages of the multi-page document. The second set of image slices printed adjacent to the edges of the long pages. Thereafter, the multi-page document is created by interleaving the long pages with short pages to enable visibility of the first set of image slices and the second set of image slices printed adjacent to the edges of the long pages.
