Portable Terminal Page Sequencing via Contour Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems struggle to output image data in the correct page sequence when the portable terminal does not transmit the data in accordance with the page sequence, leading to incorrect printing of multi-page documents.
Innovation Solution
The image processing system employs a portable terminal with a control unit, imaging unit, and storage unit that executes processes to extract and transmit image data in units of pages based on contour detection and distance sensing, ensuring accurate page sequencing and transmission to the image forming apparatus, which then corrects image data for printing.

Engineering Contradiction Analysis
1Productivity
If the portable terminal transmits image data without page sequence management, then the transmission process is simple and fast, but the printing output becomes incorrect and pages are not in proper sequence
Solution Approach 1:
The portable terminal performs preliminary actions by detecting page boundaries and determining page sequences before transmission. The control unit identifies contour lines to separate pages and assigns sequence information to each page's image data in advance, ensuring correct printing order without compromising transmission efficiency.
Solution Approach 2:
Sequence information acts as an intermediary element between the portable terminal and image forming apparatus. This metadata tag attached to each page's image data enables the receiving device to correctly reorder pages during output, resolving the sequence accuracy issue while maintaining simple transmission protocols.
2Manufacturing precision
If the system uses contour detection and distance sensing to identify page boundaries, then page sequence accuracy is improved, but the processing complexity increases
Solution Approach 1:
The system performs self-service by using the portable terminal's built-in imaging unit and distance sensor to automatically detect page boundaries and determine sequences. The control unit processes the captured image data and distance information locally to identify contour lines separating pages, eliminating the need for external scanning equipment or manual intervention.
Solution Approach 2:
The patent replaces mechanical scanning systems with optical and electronic detection methods. The imaging unit captures document images, the distance sensor measures distances to detect page separations, and the control unit uses image processing algorithms to identify contour lines, substituting mechanical page-by-page scanning with non-contact optical detection.
3Ease of operation
If the portable terminal automatically detects and transmits each page with sequence information, then user labor is reduced, but the data processing and transmission overhead increases
Solution Approach 1:
The portable terminal performs self-service by automatically capturing document images, detecting page boundaries using contour analysis, determining page sequences, and transmitting each page with embedded sequence information. This automation eliminates manual page-by-page scanning and sequencing operations, reducing user labor to simply placing the document on the imaging surface.
Solution Approach 2:
The system performs preliminary processing actions by automatically detecting page boundaries and assigning sequence numbers to each page before transmission. The control unit analyzes contour lines in the captured image, separates pages accordingly, and prepends sequence information to each page's data stream, so that the receiving device can immediately process pages in correct order without additional user intervention.
