Image Processing Apparatus Copy Prohibition Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current copying machines lack effective mechanisms to prevent the unauthorized copying of specific documents, such as banknotes and securities, and fail to enforce copy prohibitions marked on book originals during scanning.
Innovation Solution
An image forming apparatus with a scanning unit, image processing unit, and control panel that allows users to register and detect specific images, enabling storage control based on pre-set information to prohibit copying of marked pages or entire documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the copying machine scans all book originals regardless of copy prohibition marks, then scanning speed and productivity are maintained, but unauthorized copying of prohibited documents cannot be prevented
Solution Approach 1:
The system performs preliminary scanning of the entire book original to detect copy prohibition marks before final copying decisions are made. This preliminary detection phase allows the system to identify prohibited pages in advance, enabling selective copying control without compromising overall scanning efficiency.
Solution Approach 2:
The book original is divided into individual pages, and copy prohibition control is applied segment by page rather than to the entire book. This segmentation allows the system to scan and process the complete book efficiently while selectively prohibiting copying only of specific pages that contain prohibited content, thus maintaining productivity while ensuring reliability.
2Reliability
If the copying machine implements detailed image registration and detection mechanisms, then copy prohibition enforcement is improved, but device complexity increases
Solution Approach 1:
The system creates a digital copy or representation of the book original that includes metadata about copy prohibition marks. This copied information structure allows the system to enforce copy prohibitions based on detected marks without requiring complex hardware modifications to the physical scanning and copying mechanism.
Solution Approach 2:
The control unit acts as an intermediary between the scanning unit and the copying mechanism. It receives scan data, detects copy prohibition marks, and based on this detection, controls whether copying should proceed. This intermediary layer simplifies the overall system architecture by centralizing the decision-making logic in software rather than requiring complex interconnections between hardware components.

AI summary
An information processing apparatus includes a setting unit, a detector and a controller. The setting unit sets setting information associating a registered image obtained by reading an image with control information indicating whether input image data is to be stored or not. The detector detects the registered image from the input image data. The controller controls whether or not the input image data including the registered image is stored in a storage based on the setting information.
