Imaging Apparatus Feature Data Replacement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses for individual authentication require users to manually re-enter face registration mode to update feature data, leading to inefficiencies and reduced authentication accuracy due to outdated feature data, especially as objects, like faces, change over time.
Innovation Solution
An imaging apparatus with a selection unit that allows users to replace old feature data when the upper limit is reached, displaying a selection screen to choose which data to update, ensuring continuous accuracy and usability by preventing interference from accidental shutter button operations during registration processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the face registration mode ends after registering one feature data, then the registration process is simple and quick, but multiple feature data cannot be registered for the same object without re-entering the registration mode
Solution Approach 1:
The registration mode dynamically adapts its behavior based on the registration status. When the upper limit is not reached, it allows continuous registration without exiting. When the upper limit is reached, it automatically transitions to replacement mode, eliminating the need for manual mode re-entry while maintaining operational simplicity.
Solution Approach 2:
The registration mode remains active and continues to accept registration operations even after reaching the upper limit, by automatically switching to replacement mode. This continuous operation eliminates interruptions and re-entry requirements, improving registration efficiency.
2Stability of the object's composition
If the registered feature data is not updated, then the authentication system maintains stability, but authentication accuracy decreases over time as objects change
Solution Approach 1:
The system enables periodic updating of feature data through the replacement function. When the upper limit is reached, users can periodically replace old feature data with new captures, ensuring authentication accuracy is maintained over time while preserving system stability through controlled updates.
Solution Approach 2:
The system allows changing the feature data parameters by replacing existing data with newly captured data. This parameter update mechanism maintains authentication accuracy by reflecting current object characteristics while preserving the overall system structure.
3Speed
If the shutter button operation changes to image-capturing mode during registration processing, then quick mode switching is achieved, but the registration processing is interfered with and work contents are discarded
Solution Approach 1:
The system preemptively prevents harmful mode switching during registration processing by detecting the registration state and blocking the shutter button's mode-switching function. This preliminary protective action prevents registration interference while allowing normal mode switching when registration is not active.
Solution Approach 2:
The control unit acts as an intermediary that mediates between the shutter button operation and the registration processing. It intercepts the mode-switching signal during registration, prevents the harmful transition, and maintains the registration process integrity while still allowing quick operation response.

AI summary
Even when as an object targeted for registering feature data, an object for which registered feature data has reached an upper limit is selected, replacement of the registered feature data is prompted to register new feature data. An imaging apparatus includes a registration unit configured to register a plurality of feature data up to an upper limit number in association with the same object, a selection unit configured to select one of registered objects for which new feature data is to be registered, and a control unit configured to perform control to display a selection screen for allowing, when the object selected by the selection unit is the object for which the upper limit number of feature data has been registered, a user to select the feature data to be replaced with the new feature data among the upper limit number of feature data registered for the object.
