SOLVED IMX462 parameters
-
Hello everyone, I'm setting up the Veye_mipi IMX462 camera connected to the raspberry pi4. following the instructions on the User Guide VEYE-MIPI-290/327 I2C.sh page. it happens that after I make the changes to the parameters, when I turn off raspberry, the camera returns to the original parameters. is this normal or am i doing something wrong?

hi，
I think this is normal, the VEYE series of cameras do not have the ability to save parameters. Therefore, each power outage causes the parameters to return to their default values. -
some images are appearing horizontal interfering lines, could this be some incorrect adjustment in the settings?

@fabricio-borges
I feel that this phenomenon is not the direct output of the camera, but the problem caused by the follow-up processing.
The horizontal line that goes wrong, is it in a fixed position, does it appear all the time?
How did you capture this picture? What processing has been done after the camera output? -
@veye_xumm , i found that the cause of the interference in the image was the flat cable. after the exchange the problem was solved. I am now making camera adjustments and am confused by the instructions. how can i adjust the parameters to keep the camera with 40 millisecond exposure time and 25 fps?

pls use mshutter 0x41 -
@veye_xumm Thanks for the answer. I have another question. I notice that in some images when a cloud passes, the background becomes darker. How can I set the camera to disable this mode?

The AE algorithm evaluates the current image brightness and adjusts shutter and gain so that the image brightness is within a small range around the set value. In your usage scenario, white clouds will slowly drift by, and may occupy a significant area in the image. The brightness of the white clouds at night is much brighter than the sky, which causes the AE algorithm to evaluate the significant changes in the overall environmental brightness with the white clouds.
I feel that there is no way to keep this situation constant unless you use fully manual exposure. However, this will cause more serious problems. The camera loses its ability to adapt to the scene, so this is not recommended. -

This question has been asked for a long time and the status has not been updated. I will mark the status as solved, so you can follow up again if needed, or just open the question.
