Imaging Device Audio Correction for Self-Shooting Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices struggle to accurately capture and playback audio during self-shooting modes, as conventional methods rely solely on microphone direction weighting or frequency band adjustments, which may not align with the operator's intentions due to varying subject conditions.
Innovation Solution
An imaging device equipped with a specified-subject detection part, direction-relationship detection part, and audio-correction part that adjusts audio processing based on the detected subject and relative display-shooting direction relationship, ensuring optimal audio capture and playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio processing is performed based solely on microphone direction weighting, then the device complexity remains low, but the audio accuracy does not align with operator intentions in self-shooting modes
Solution Approach 1:
The audio processing system dynamically adapts its behavior based on the detected shooting mode. When self-shooting mode is detected (display direction matches shooting direction), the system applies different audio correction processing compared to ordinary shooting modes. This dynamic adaptation allows the system to optimize audio accuracy for different operational contexts without requiring permanently complex processing for all scenarios.
Solution Approach 2:
The system changes processing parameters based on the relationship between display direction and shooting direction. By detecting whether the display part is oriented in the same direction as the imaging part, the system adjusts audio correction parameters accordingly, enabling accurate audio capture in self-shooting modes while maintaining simplicity in other modes.
2Adaptability or versatility
If the same audio processing is applied regardless of shooting mode, then the processing method is simple, but the audio quality does not meet operator expectations in self-shooting scenarios
Solution Approach 1:
The audio processing system dynamically adapts its behavior based on the detected shooting mode. When self-shooting mode is detected (display direction matches shooting direction), the system applies different audio correction processing compared to ordinary shooting modes. This dynamic adaptation allows the system to optimize audio accuracy for different operational contexts without requiring permanently complex processing for all scenarios.
Solution Approach 2:
The system uses feedback from the direction-relationship detection to adjust audio processing. By continuously monitoring the relative orientation between the display part and imaging part, the system receives feedback about the current shooting mode and automatically adjusts audio correction parameters to match operator intentions, achieving adaptability through closed-loop control.
3Ease of operation
If the display part is rotated to enable self-shooting, then the ease of operation improves, but the audio capture accuracy deteriorates due to mic direction mismatch
Solution Approach 1:
The audio processing system dynamically adapts its behavior based on the detected shooting mode. When self-shooting mode is detected (display direction matches shooting direction), the system applies different audio correction processing compared to ordinary shooting modes. This dynamic adaptation allows the system to optimize audio accuracy for different operational contexts without requiring permanently complex processing for all scenarios.
Solution Approach 2:
The system changes processing parameters based on the relationship between display direction and shooting direction. By detecting whether the display part is oriented in the same direction as the imaging part, the system adjusts audio correction parameters accordingly, enabling accurate audio capture in self-shooting modes while maintaining simplicity in other modes.

AI summary
The imaging device is provided with at least one imaging part to obtain images through shooting and at least one sound-collection part to obtain audio, collecting it together with the shooting of the imaging part, and at least one display part to display images. It performs audio-correction processing of audio obtained through the sound-collection part according to the relative relationship between the direction in which the display part displays images and the direction in which the imaging part shoots.
