Image denoising
Learn what image denoising means, how it relates to webcam video, and why it differs from microphone noise reduction.
What is image denoising?
Image denoising is an image-processing function that reduces unwanted visual noise, such as grain or speckles, in a photograph or video frame. Photo noise reduction is another common name for this process when applied to still images.
What does it mean for a webcam?
For a webcam, image denoising concerns the picture. Its purpose is to make the captured image look cleaner while preserving useful detail. It describes a processing function, rather than a microphone component or an audio property.
Does image denoising reduce microphone noise?
No. Image denoising processes visual information. Microphone noise reduction processes captured sound. An image-denoising setting therefore does not, by itself, indicate that background sound will be reduced.
The supplied information does not identify a webcam model, application or operating system. It cannot establish whether a particular setup offers image denoising, where its controls appear or how effective it is.
