Multi-Camera Facial Authentication With Target-Based Camera Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In facial recognition systems using multiple cameras, continuous processing by all cameras leads to inefficient power consumption and reduced device durability due to unknown target appearances, as cameras are activated without targets for extended periods.
Innovation Solution
An information processing device that searches for a suitable camera among non-activated cameras based on the target's estimated position and angle from an active camera's image, activating only the necessary cameras for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are continuously activated to detect targets, then recognition accuracy is improved, but power consumption increases significantly
Solution Approach 1:
The patent applies dynamics by transitioning from static continuous activation of all cameras to dynamic selective activation. The system dynamically determines which cameras to activate based on real-time target detection results. When a target is detected by one camera, the system activates other cameras only when needed for authentication, creating a flexible, adaptive operation mode that balances accuracy requirements with energy conservation.
Solution Approach 2:
The patent implements periodic action through the cyclic detection-activation pattern. Cameras are activated periodically based on detection needs rather than continuously. The system enters a detection phase with active cameras, processes target authentication, and then returns to a standby state, creating periodic cycles of activation and inactivity that reduce overall energy consumption while maintaining readiness.
2Reliability
If multiple cameras are continuously activated for facial recognition, then authentication reliability is improved, but device durability decreases
Solution Approach 1:
The system dynamically adjusts camera operation states based on authentication needs. Instead of continuous operation that degrades hardware, the system activates cameras only during authentication-critical periods. This dynamic state management maintains authentication reliability when needed while preserving device durability through reduced operational stress on camera components.
Solution Approach 2:
The patent applies discarding and recovering by deactivating cameras after they complete their detection and authentication function. Cameras are discarded from active service after use and recovered to standby state, rather than remaining continuously active. This cycle of activation and deactivation reduces cumulative wear on camera components, extending device durability while maintaining authentication reliability through selective reactivation.
3Adaptability or versatility
If all cameras are activated continuously, then coverage of all angles is ensured, but unnecessary processing increases energy waste
Solution Approach 1:
The patent applies segmentation by dividing the camera system into functional groups based on spatial coverage needs. Instead of activating all cameras uniformly, the system segments camera activation based on target position and authentication requirements. Cameras are selectively activated only for the specific angular coverage needed for the current detection task, eliminating unnecessary processing and energy waste from fully-activated cameras that don't contribute to the current authentication objective.
Solution Approach 2:
The system implements local quality by applying different operational states to different cameras based on their spatial contribution. Not all cameras are treated equally; instead, each camera's activation state is optimized for its local role in the detection- authentication process. This ensures that only cameras providing necessary angular coverage are active, while others remain inactive, reducing overall energy waste while maintaining adequate coverage quality.

AI summary
There is provided an information processing apparatus, an information processing method, and a program that allow for reduction in power consumption in authentication using multiple cameras. The information processing device performs camera search processing of searching for a camera suitable for authentication of a target among non-activated cameras yet to be activated, on the basis of a position and an angle of the target estimated from an image captured by an active camera which is an activated camera among multiple cameras, and activating the camera found by the search. The present technology can be applied to facial recognition systems.
