Well, this is obviously not true. As we change dmeshutter right before the frame and always get it correct with the new shutter value. As for dmegain it indeed requires to be set 1 frame in advance (not 2). Although I do not understand why it works this way if we are setting those values directly to the sensor and what is the reason of making direct settings to the sensor as opposed to setting it in the ISP if it would converge only after N frames even with direct setting.

Anyway the problem we are experiencing is with lost frames rather than incorrect shutter/gain values.

@veye_xumm

The range is approximately from 3 to 15 frames per second at varying intervals. We set dmeshutter value before every frame.

@veye_xumm
We currently do not have a camera to try this on. Hopefully one arrives soon. But it is weird that this only happens at specific range of dmeshutter. Dmeshutter is set before each frame is triggered.

@veye_xumm
Yes, we have thoroughly studied every article related to the camera. There seems nothing we are doing wrong.

Hi!

We are experiencing consistent lost frames with software trigger at shutter speed from roughly 12ms to 22ms. At other shutter speeds there are no lost frames or they are extremely rare.

I was expecting it to be 1 - 34ms frame output delay (1ms shutter) + <60ms transfer time + ~5ms for pipe conversions which should take us to a total of 65 - 100ms. Whereas we never get less than 110-120ms.

We have timed a latency of actual optical image in realtime to gstreamer appsink to be about 140ms. Is there any way to reduce it?

Here's the gstreamer pipe "nvv4l2camerasrc ! video/x-raw(memory:NVMM), format=(string)UYVY, width=(int)1920, height=(int)1080 ! nvvidconv ! video/x-raw(memory:NVMM) ! nvvidconv ! video/x-raw ! appsink max-buffers=1 drop=true"

Completely turning off denoise fixes the issue. This frame was captured on lowest default denoise levels. Thanks.

Hi!

We are acquiring images with gstreamer on jetson nano with IMX327. Images of moving white coloured/bright objects have a subtle shadow of their previous position. Like the license plate and headlights in the image below. Adjusting shutter speed or any other parameters does not make any difference.

Is there anything that can be done about this or is this a hardware issue?
