Image Reading Apparatus Two-Page Spread Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for imaging and recording book pages struggle to stably detect page ends, often confusing them with folding portions, and record two-page spreads as single images, leading to erroneous page turning detection and inefficient image processing.
Innovation Solution
An information reading apparatus that analyzes photographed images to determine if a medium is in a two-page spread layout and divides the image accordingly, using criteria such as image change direction and area to accurately judge and process each page independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If page end side position change is used to detect page turning, then page turning detection can be performed, but detection accuracy deteriorates due to confusion with folding portions
Solution Approach 1:
The patent segments the photographed image into multiple regions (first region and second region) divided by a reference line. By analyzing page end position changes separately in each region, the system can distinguish actual page turns from folding portions, thereby improving detection accuracy while maintaining automation.
Solution Approach 2:
The patent introduces a reference line as an intermediary element to divide the image into separate analysis regions. This reference line serves as a mediator that helps differentiate between genuine page end positions and folding portions, enabling more accurate automated detection without requiring complex algorithms.
2Productivity
If entire two-page spread is photographed at once, then imaging efficiency is improved, but image processing complexity increases due to need to separate pages
Solution Approach 1:
The patent automatically segments the photographed two-page spread image into separate first and second region images based on a reference line. This segmentation allows efficient processing of each page independently while maintaining the benefit of capturing both pages in a single shot, thus reducing overall processing complexity.
Solution Approach 2:
The system performs self-service by automatically dividing the two-page spread image into separate page images without requiring manual intervention. The judging section autonomously determines whether division is needed and executes the separation, simplifying the workflow while handling complex image processing tasks.
3Quantity of substance
If two-page spread data is recorded as single image, then storage efficiency is improved, but page-level processing capability deteriorates
Solution Approach 1:
The patent provides flexible segmentation capability that can operate at different levels. When needed, it segments the two-page spread into separate page images for individual processing, while still allowing the option to store the original combined image, thus maintaining both storage efficiency and page-level processing adaptability.
Solution Approach 2:
The system dynamically adjusts its processing mode based on requirements. It can switch between treating the two-page spread as a single image or dividing it into separate pages, providing adaptable processing capability that responds to different operational needs without sacrificing storage efficiency.

AI summary
An information reading apparatus of the present invention is an information reading apparatus which photographs an information recording medium having information recorded thereon and reads the information. This information reading apparatus includes a judging section which judges whether the information recording medium is in a two-page spread layout by analyzing a photographed image of the information recording medium, and a dividing section which divides the photographed image of the information recording medium into the pages of a two-page spread when the judging section judges that the information recording medium is in a two-page spread layout.
