IMX462 raspberry PI

Tested, it seems that the problem lies in the --immediate parameter, there is no problem without this parameter.

Thank you very much Wong,

Is possible to get rid of the preview pop-up window?

Thank you

Andrei

You can add the -n parameter, but the flow doesn’t change except that there is no preview window:

  1. First open the small resolution preview (and adjust AF, AWB, AE),
  2. After reaching the specified time, switch to large resolution to take pictures.

Thank you for great information.

I was planning to use this camera for astrophotography… the sensor is known for the lowest noise level…

Unfortunately I doubt this is possible.

I was able to make the image brighter by increasing exposure time until 1s… above this value it was no improvement… there is a solution to fix this?

I tried to make the image brighter by increasing the gain, it worked up to gain of 100x but when trying 1000x it was no improvement… can this be fixed.

Least but not last, I process my image in windows… I can open pictures taken with exposure time under 1s , the ones with 1s or higher can not be opened ???

Please help. it is a pity for such a great sensor not to be able to make picture with exposure above 1s gain higher than 100x and to be opened in win…


I can not attached the bad image files, not even as zip…

How do you adjust AF, AWB and AE?

I have a preview window open but the AF, AWB and AE parts I don’t understand.

Or maybe you mean a preview in the GUI? I’m running headless.

When I start my app I get:
