Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the imaging unit captures images without notification to the user, then the extraction process can proceed automatically, but the user cannot easily perform extraction operations effectively
Solution Approach 1:
The notification unit provides real-time feedback to the user about the positional relationship between the imaging unit and the printed matter. This feedback mechanism enables the user to understand whether the current position is suitable for extraction, thereby improving the ease of operation without losing critical positional information.
Solution Approach 2:
The system performs preliminary assessment of the positional relationship and notifies the user before the extraction process begins. This allows the user to adjust the position in advance if needed, making the extraction operation easier and more effective.
2Measurement precision
If the system requires precise positional relationship between imaging unit and printed matter, then extraction accuracy improves, but user operability becomes more difficult
Solution Approach 1:
The notification unit communicates the degree of positional suitability to the user, providing guidance on whether adjustment is needed. This feedback reduces the burden on the user to precisely control positioning while maintaining extraction accuracy through informed operation.
Solution Approach 2:
The system evaluates multiple parameters of the positional relationship (distance, angle, orientation) and transforms this complex information into simple notification messages, making it easier for users to operate while maintaining precision requirements.
3Measurement precision
If the notification unit provides detailed positional feedback, then extraction accuracy improves, but device complexity increases
Solution Approach 1:
The notification unit provides essential positional feedback in a simplified format that maintains extraction accuracy without requiring complex system architecture. The feedback is targeted and sufficient for user needs rather than providing exhaustive technical data.
Solution Approach 2:
The system extracts only the critical positional relationship information needed for accurate extraction and presents it through the notification unit, rather than processing and managing all possible positional parameters, thereby reducing system complexity.

AI summary
An image processing apparatus includes an imaging unit configured to capture an image of a printed matter in which additional information has been embedded by an electronic watermark and an extraction unit configured to perform an extraction process of extracting the additional information from captured image information obtained by the imaging unit. The image processing apparatus further includes a notification unit configured to notify information indicating that the imaging unit is in a stage of preparation for the extraction process in a case where a positional relationship between the printed matter and the imaging unit satisfies some of conditions for starting the extraction process.
