Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing devices face a decrease in convenience due to authentication cancellation during continuous image capture, as described in Japanese Patent Laid-Open No. 2018-191194.
Innovation Solution
An imaging device that identifies a user, determines the state of continuous use, and records user information with captured images between identification and discontinuation of use, using biometric methods like iris recognition, and associates photographer information with captured images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If authentication is monitored continuously and canceled upon biometric information change, then photographer identification accuracy is improved, but convenience of image capturing deteriorates due to authentication interruption during continuous shooting
Solution Approach 1:
The patent applies dynamics by making the authentication state adaptable to different usage scenarios. The system dynamically switches between strict authentication monitoring (when still images are captured) and lenient authentication monitoring (when moving images are captured), allowing the authentication behavior to change based on the capture mode. This resolves the contradiction by making the system flexible enough to maintain accuracy when needed while preserving convenience during continuous shooting sequences.
Solution Approach 2:
The patent changes the authentication parameter based on the type of image capture. When moving image capture is detected, the system modifies the authentication monitoring parameter to allow continued authentication despite biometric changes, whereas for still images it maintains strict monitoring. This parameter change enables the system to balance identification accuracy with capturing convenience depending on the operational context.
2Reliability
If biometric monitoring is performed to identify photographer changes, then copyright management reliability is improved, but image capture productivity deteriorates due to authentication cancellation interrupts
Solution Approach 1:
The system dynamically adjusts authentication monitoring based on capture mode. During moving image capture, the system maintains photographer identification reliability by continuously monitoring while allowing the capture process to continue uninterrupted, whereas for still images it uses stricter monitoring that may interrupt capture. This dynamic approach preserves copyright management reliability without sacrificing productivity during video recording.
Solution Approach 2:
The patent changes the authentication monitoring parameter based on whether moving images are being captured. When video capture is detected, the system modifies the monitoring parameter to continue authentication without canceling it upon biometric changes, thereby maintaining reliability while preserving capture productivity. This parameter adjustment allows the system to handle different capture scenarios optimally.
3Ease of operation
If authentication is maintained during continuous use, then convenience of image capturing is improved, but photographer identification accuracy may deteriorate if user changes occur undetected
Solution Approach 1:
The system dynamically adjusts authentication monitoring based on capture mode. For still image capture, it maintains strict monitoring to ensure identification accuracy even if convenience decreases. For moving image capture, it adopts a more lenient approach that prioritizes convenience while still performing monitoring. This dynamic adjustment allows the system to optimize for the appropriate parameter depending on the operational context.
Solution Approach 2:
The patent changes the authentication monitoring parameter based on the type of capture operation. When still images are captured, the system uses a parameter that prioritizes identification accuracy by canceling authentication on biometric changes. When moving images are captured, it switches to a parameter that maintains convenience by continuing authentication despite biometric changes, thus resolving the contradiction through context-dependent parameter selection.

AI summary
An imaging device comprises at least one processor and at least one memory having stored thereon instructions which, when executed by the at least one processor, cause the imaging device at least to identifying a user of the imaging device, determining a state of continuous use of the imaging device by the user, and performing control such that information of the user is recorded in a memory in association with an image captured by the imaging device between a time at which the user is identified and a time at which it is determined that use of the imaging device by the user is not continuing.
