Mobile Terminal Face Recognition via Raised State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals require cumbersome operations for face recognition, involving waking up the device, activating the camera, and adjusting orientation, leading to longer recognition times and reduced convenience.
Innovation Solution
A face recognition method that automatically detects when a mobile terminal is raised from a stationary state, activates the camera, captures an image, and performs face recognition against a preset template, allowing for quick and convenient unlocking or permission management.

Engineering Contradiction Analysis
1Ease of operation
If the user manually wakes up the mobile terminal, activates the camera, and adjusts orientation for face recognition, then the face recognition function can be implemented, but the operation process becomes cumbersome and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically waking up the mobile terminal and activating the camera when it detects that the user is about to perform face recognition (through sensor detection of device state changes), eliminating the need for manual wake-up and camera activation steps
Solution Approach 2:
The mobile terminal automatically detects its own state changes (from stationary to raised position), self-activates the camera, and self-adjusts to the correct orientation for face recognition, making the system serve itself without requiring manual user intervention for these preparatory steps

AI summary
The present disclosure provides a face recognition method and a mobile terminal. The method includes: detecting whether a mobile terminal switches from a stationary state to a raised state; activating a camera and capturing an image by the camera, when the mobile terminal switches from the stationary state to the raised state; judging whether the image matches a preset face template; and determining that recognition is successful when the image matches the preset face template.
