B0433 camera unable to change exposure time from v4l2

USB UVC Webcams

  1. Where did you get the camera module(s)? arducam.com

  2. Model number of the product(s)? B0433

  3. What hardware/platform were you working on? Linux Ubuntu

  4. Instructions you have followed. (link/manual/etc.) I followed v4l2 on how to set exposure and capture raw image

  5. Problems you were having? No matter what exposure_absolute value I give to the camera, the imae doesn’t change. It looks like the frame rate is what decides the exposure time.
    I tried using the camera from the windows application and had no problems with changing the exposure time manually. I don’t understand if it’s a camera module problem or is v4l2 problem

Hi,
Which command did you use to change exposure value?

I used this
v4l2-ctl --set-ctrl=exposure_auto=1 --set-ctrl=exposure_absolute=*any number between 3 and 2047

What I found out yesterday is that it might be just a driver issue of the camera. Because by adding the command to skip frames, the exposure changes. Or at least it seems to be working now
