Relationship between gain exposure and uvc's brightness

  Hi Tsubota Kazuhiro  In terms of RGB, exposure, gain and brightness will all affect the brightness level of the image.  There is not a relationship between them though in the sense that changing one of these RGB settings will automatically affect the other two.

   

  Changing exposure or gain manually will though automatically disable Auto-Exposure and so if you need auto-exposure then you could adjust the brightness instead, as doing so does not affect auto-exposure.

   

  In terms of depth exposure and gain (there is not a depth brightness option), setting a manual value for these also disables Auto-Exposure.  Increasing the depth gain adds noise to the depth image, causing it to progressively break up as the gain is increased.

  Hi MartyG Thanks for your quick reply. Gain and brightness are independent effect for each, right?
  I'm interested in the order of two image process. Is this correct  gaining image level first , then,  brightness process done ?

  As the settings do not affect each other but they all independently increase brightness, it should not matter which one is changed first.
