Camera Audio Guidance for Face Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photography systems fail to capture high-quality images when the target is not facing the camera, resulting in suboptimal image effects.
Innovation Solution
An electronic device with a photographing system that includes a camera, storage device, processor, and speaker, utilizing modules for predetermination, detection, control, determination, and acquisition to emit attention-drawing audio and adjust volume or flash settings to ensure the target's face is squarely facing the camera before capturing an image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera captures images without requiring the target to face the camera, then the ease of operation is improved, but the image quality deteriorates
Solution Approach 1:
The system performs preliminary actions by emitting attention-drawing audio before image capture to guide the target to face the camera properly. The detection module detects whether the target's face is squarely facing the camera before capturing the image, ensuring proper alignment is achieved in advance of the actual image capture.
Solution Approach 2:
The system implements feedback by continuously detecting the target's facial orientation and providing real-time guidance through audio signals. The determination module determines whether the face is properly aligned and provides feedback through audio to adjust the target's position until proper alignment is achieved.
2Manufacturing precision
If the system emits attention-drawing audio to ensure proper face alignment, then the image quality is improved, but the device complexity increases
Solution Approach 1:
The speaker module serves multiple functions: it emits attention-drawing audio to guide the target to face the camera, provides feedback during the alignment process, and can indicate when the face is properly aligned. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The system uses the camera's own detection capabilities to automatically determine face alignment and triggers audio feedback accordingly. The detection module and determination module work together to self-regulate the imaging process without requiring external intervention or complex additional hardware.

AI summary
A method for taking image of face which is executable on an electronic device requires a speaker and a camera. An activation of the camera is detected and the speaker is controlled to emit sound from an audio file to draw attention of a target. If the face of the target is not facing the camera for a predetermined duration, a volume of the emitted sound is increased or another audio file replaces the currently played audio file and the camera is triggered to take an image of the target when the target is fully facing the camera.
