Problem with GXC-MIPI-IMX662

[alex_ai]

Hi @veye_xumm,
I’ve just received your new sensor. While testing it, I noticed that the image keeps jumping for some reason, even though the camera is completely static. I’ve attached a sample video (renamed to txt). It looks like the image is stretching near the bottom of the frame, which creates a twitching/jittering effect. Is there any way to fix this?

Rpi5, drivers updated to recent, sensor firmware version 01.32 2.19

@alex_ai Apologies for the delayed response. I would like to know if there is any vibration or shake in your actual application scenario. Could you please try turning off the 3D Noise Reduction (3DNR) to see if there is any improvement?

Hi @veye_xumm,
As I wrote - camera is static, no vibration. Turning off of 3D Noise Reduction didn't help. I also tried with test image - it also has this issue on the last line at the bottom of frame (see attached renamed to txt video file)

I believe the issue does not lie with the camera output, but rather with the compression process after you receive the data. Please verify this using the client software available at the link below. The veye_viewer client is designed to preview raw grey format data directly, without applying any compression.

Hi @veye_xumm, all videos captured from veye_viewer (you can see it on first video)

@alex_ai Sorry, I misunderstood your setup. I've verified this on other boards, including Jetson, and it works fine. I now believe the issue is caused by image scaling in the veye_viewer client software on the latest Raspberry Pi OS. We'll fix this as soon as possible — please bear with us.
