In the R-Pi VC4 document at https://github.com/raspberrypi/firmware ... amera.html I see reference to OMX_IndexConfigVideoColourDenoiseEnable, OMX_IndexConfigStillColourDenoiseEnable, and OMX_IndexConfigTemporalDenoiseEnable.
It notes that "This is only applicable whilst the camera is producing images in the Broadcom-specific format or YUV420." but I am wondering if this kind of denoise control is available in raspiyuv or raspistill ? If not, could it be? I would love to be able to try capturing image with no or reduced noise filtering, without resorting to RAW format which is a lot more trouble to deal with.
