Dual Camera Mobile Terminal Attention Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of dual camera-enabled mobile terminals face challenges in maintaining focus and adjusting zoom conditions while recording videos, as they need to monitor the viewfinder or display screen, leading to potential distractions and undesirable video results.
Innovation Solution
An image capturing control apparatus and method that utilizes both front and rear cameras to monitor the user's state, detect face recognition, and adjust zoom conditions automatically when the user's attention is diverted or distance changes, providing alerts and corrections to ensure the intended scene is captured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user monitors the viewfinder or display screen while recording video, then the user can control the capture process, but the user's attention is distracted from the target view, causing the focusing point to change and resulting in undesirable video quality
Solution Approach 1:
The system uses the front camera to continuously monitor the user's face and gaze direction, providing feedback about whether the user is looking at the display screen or the target view. This feedback mechanism enables automatic detection of user attention state without requiring the user to consciously monitor their own behavior
Solution Approach 2:
The system performs self-monitoring by automatically detecting the user's attention state through the front camera and autonomously adjusting capture parameters or providing warnings, eliminating the need for the user to manually control both the monitor and the capture process simultaneously
2Reliability
If the user uses the rear camera to capture scenes, then the user can acquire desired images, but the user must manually manipulate buttons or lenses to adjust zoom conditions, increasing operation complexity
Solution Approach 1:
The system automatically adjusts the zoom condition of the rear camera based on the detected user attention state and scene analysis, performing the zoom adjustment function autonomously without requiring manual user manipulation of buttons or lenses
Solution Approach 2:
The patent replaces the manual mechanical zoom adjustment (buttons or lens manipulation) with an automated system that uses front camera detection and control unit processing to electronically adjust the rear camera zoom, substituting mechanical user interaction with automated electronic control

AI summary
Methods and apparatus for image capturing are provided. A first camera mounted on a rear side of a mobile terminal, and a second camera mounted on a front side of a mobile terminal, are driven in an image capturing mode. A user's face is detected in a second image generated by the second camera. An alarm is generated that indicates that a first image is out of an intended image capturing area, when the user's face is not detected in the second image and when a difference is detected between the first image and a reference first image.
