Camera App Pattern Code Trigger Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices lack the ability to easily recognize and process pattern codes within images captured using their camera applications, requiring separate applications for QR codes and barcodes, and do not provide simultaneous display of image capturing and pattern code triggers.
Innovation Solution
A mobile device with a camera unit, display unit, and sensor unit, controlled by a processor that provides an image capturing interface displaying both an image capturing trigger and a pattern code trigger only when a pattern code is recognized, allowing for automatic focus adjustment and storage of image and pattern code information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate application is used for QR codes and barcodes, then pattern code recognition capability is improved, but device complexity and ease of operation deteriorate due to requiring multiple applications
Solution Approach 1:
The patent merges the pattern code recognition function into the existing camera application by displaying a pattern code trigger within the camera interface. When the camera captures an image containing a pattern code, the system automatically recognizes it and allows the user to access pattern code information through the same interface used for regular photo taking, eliminating the need for separate QR code or barcode scanner applications.
Solution Approach 2:
The camera application is enhanced to perform multiple functions: regular image capturing and pattern code recognition. By integrating the pattern code trigger display and recognition capability into the universal camera interface, the system allows a single application to handle both photographing and pattern code scanning tasks, improving versatility while reducing the number of required applications.
2Adaptability or versatility
If pattern code trigger is always displayed, then pattern code recognition capability is improved, but ease of operation deteriorates due to interface clutter when pattern code is not present
Solution Approach 1:
The pattern code trigger display is made dynamic rather than static. The trigger is automatically displayed only when the camera detects that the captured image contains a pattern code. This dynamic adjustment of the interface elements ensures that the pattern code recognition capability is available when needed, while maintaining interface simplicity and avoiding clutter when pattern codes are not present in the scene.
3Measurement precision
If automatic focus adjustment is implemented, then measurement precision is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system implements automatic focus adjustment that operates autonomously when pattern codes are detected. The camera application automatically adjusts focus to the pattern code area without requiring manual user intervention, and the processing is integrated into the existing image capture workflow. This self-service approach improves measurement precision for pattern code recognition while minimizing additional complexity by leveraging existing camera and processing infrastructure.
