I have met with a problem with Bluerobotics low light camera on board our ROV. The video feed from the QGC was flickering during operation. I will explain the scenario:
The scenario was that ROV was powered off and was under the sun for a prolonged duration of time (~ 3hrs). Afterward, during operation, the camera feed was flickering for around 1 hrs even during dive (~ depth: 25m). After the one hour mark, the flickering decreased drastically.
We have experienced this whenever the ROV was under sunlight. But the extent of flicker was very high during this time.
What do you think is the root cause of this flicker?
