• Manually iso sensitivity compensation

Hello,

Is it possible to change the sensitivityIso for the RGB image on the oak-d pro poe when setAutoExposureEnable() is on or at least pull it towards a higher number, it is currently at 100, even though the image is quite dark.

rgb_ctrl_msg = dai.CameraControl()

rgb_ctrl_msg.setAutoExposureEnable()

rgb_ctrl_msg.setAutoExposureCompensation(-6)

The outcome is then:

rgb-control:

lens-position: 131

exposure-time: 2023

iso: 100

mono-control:

exposure-time: 492

iso: 100

I have a high vibration environment, so I’m quite happy with the exposure time, but I would like a higher ISO.

Hi Robengaard

You have auto exposure compensation set to -6 which is the lower end. You should put it to >0 to brighten an image.

Hope this helps,

      Hi jakaskerl

      My challenge is that I would like a very low exposure due to my high vibration environment therefor a lower exposure compensation. To compensate for a lower exposure I would like to have a higher iso sensitivity. It seems like I can't get both a high iso sensitivity and a low exposure…

          Hi Robengaard
          Autoexposure doesn't allow manually setting sensitivity. I guess you could make it hybrid by turning on AE, waiting for the image to stabilize and then set AE to manual and manually up the ISO.

          Thanks,
          Jaka

              jakaskerl Sound like a method even though I would like a more automated solution. Thanks for taking your te to a reply.
