Image Display Apparatus Noise Reduction During Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In file-based image production workflows, the proximity of image display apparatuses to image capturing devices leads to audio data from these apparatuses being recorded as noise during the capturing and grading processes, as existing solutions either fail to integrate sound reduction with image display or do not effectively mitigate the noise issue.
Innovation Solution
An image display apparatus connected to an image capturing apparatus, equipped with a sound reduction unit that acquires recording or shooting time information to execute a sound reduction process, either by adjusting fan speed or speaker volume, to minimize noise output during image recording or reproduction processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the image display apparatus operates at full performance during image recording, then the image display quality is improved, but the sound output from the apparatus is recorded as noise in the audio data
Solution Approach 1:
The control unit receives information about the image recording process in advance and proactively reduces the sound output of the image display apparatus before the recording occurs. This preliminary action prevents the noise from being captured by the microphone, while the apparatus is ready to provide full performance when the recording information is received.
Solution Approach 2:
The system establishes a feedback loop where the control unit continuously monitors for image recording process information from the image capturing apparatus. When recording is detected, the control unit adjusts the sound output level, and when recording stops, the sound output returns to normal, creating a responsive feedback-based noise control mechanism.
2Manufacturing precision
If the sound output is reduced during image recording, then the noise in audio data is minimized, but the user experience of the image display apparatus is degraded
Solution Approach 1:
The sound output level of the image display apparatus is made dynamic rather than static. The control unit adjusts the sound output level based on real-time detection of image recording status, allowing the apparatus to adapt its performance characteristics to the current operational context, thereby maintaining both audio quality and user experience.
Solution Approach 2:
The system changes the sound output parameter (volume level) based on the operational state of the connected image capturing apparatus. When image recording is detected, the sound output parameter is reduced to prevent noise contamination, and when recording stops, the parameter returns to its original value, ensuring optimal conditions for both recording and user experience.
3Object-affected harmful factors
If existing sound reduction techniques are applied to the image display apparatus, then the noise during recording is reduced, but the cooling performance of the apparatus is compromised
Solution Approach 1:
The control system separates the management of sound output and cooling functions. The control unit independently manages the sound output level based on recording status, while the cooling fan operates based on temperature requirements. This segmentation allows both noise reduction and adequate cooling to be achieved without compromising either function.
Solution Approach 2:
The control unit proactively reduces sound output when image recording is detected, preventing noise contamination before it occurs. The cooling system continues to operate independently to maintain proper temperatures, ensuring that noise reduction does not compromise thermal management.

AI summary
The image display apparatus is connected, directly or via a recording apparatus, to an image capturing apparatus, and includes a first acquisition unit configured to acquire recording process information on an image recording process for recording, with the image capturing apparatus or the recording apparatus, moving image data generated by capturing an object with the image capturing apparatus and audio data representing audio that is input to a microphone during a shooting period of the moving image data, and a reduction unit configured to execute a sound reduction process for reducing a sound output from the image display apparatus, in a case where the image recording process is executed, based on the recording process information.
