MyWhat firmware does the camera have installed?
Over 100$ dashcam has the same issue. A129+.
Thanks!OK!!

I'm sure they could, as you would also know if they do that there's going to be a tradeoff, much less detail overall in low light situations for starters, gathering information about the scene you are in is far more important than trying to make cinema quality movies that some people seem to expectMaybe both cameras could be improved in terms of noise, but doing so would probably have a negative effect on motion blur so the change may not be desirable.
I would prefer there to be no banding, just random noise, even better no noise at all, but it is a compromise, if you reduce noise then you make other things worse.I see that you speak with figures, percents... in your great wisdom can you tell us the tolerance limit of banding, maybe you know better than us some secret specifications of Viofo's dashcams.
Exactly the same with mine on roads without light.Over 100$ dashcam has the same issue. A129+.
I see, random noise in bands. Lol. Dude, do you really think that we are blind, or we don't know what we see?I would prefer there to be no banding, just random noise, even better no noise at all, but it is a compromise, if you reduce noise then you make other things worse.
What I see in that is that the camera has adjusted the exposure between the two images, maybe because the second is on a corner so the headlights are hitting the side of the road thus brighter than when on the straight where they are illuminating the distance.Maybe you can see the difference between random noise and banding@noise in the attached picture. It's a collage with two pics taken at seconds between them (see index time).
Can you post a "roads without light" image for us to look at?Exactly the same with mine on roads without light.
As above, image sensors are analogue and there will always be some variation between samples when you push them to their limits, there are also a few other components that can vary such as power supply components that may be generating different noise levels.The thing here is that only some have these problems and some dont
I assume there was an adjustment to the exposure settings to reduce motion blur a bit at the expense of a little more noise. Maybe for people with bright headlamps this works really well, for people using paraffin lamps on their steam cars it is probably a bad change! You can't always please everyone.and why this occurs with newer firmwares but with older no?
I assure you audi matrix headlights dont work on paraffin yet the problem still exists so this "maybe" is not the answer.Maybe for people with bright headlamps this works really well, for people using paraffin lamps on their steam cars it is probably a bad change!
Hey- quit making fun of my old van At least it has a blinker fluid reservoir which some new BMW's and Audi's seem to lackMaybe for people with bright headlamps this works really well, for people using paraffin lamps on their steam cars it is probably a bad change! You can't always please everyone.
I dont expect nothing more than what was already there before. In v1.3 firmaware the picture is clear day and night without any kind of banding in the same car, same power adaptor, same everything, only firmware has changed("upgrade" ha ha).gathering information about the scene you are in is far more important than trying to make cinema quality movies that some people seem to expect
Had to look those up:I assure you audi matrix headlights dont work on paraffin
And it can light up just your lane:Its current state-of-the-art lighting, HD Matrix LED, is an adaptive system that works by splitting the traditional single headlight beam into dozens of smaller rays that can be turned on and off individually to un-light small areas in front. It uses 32 diodes per side, controlled by a forward-facing camera, and it's largely effective. The newer Digital Matrix LED units use a reflective chip about the size of fingernail that contains a million microscopic mirrors measuring a few hundredths of a millimetre each, meaning a much more accurate and pixelated beam can be generated compared with the old system's 32 big blocks of light. Visually it's the difference between playing Minecraft and the latest Call of Duty title.
Sorry, I did not see anything wrong with your English, I was just referencing your words.Excuse my french! You dont have to keep pointing "roads without light", english is not my native language.
Oh, boy! Here we go again. I don't know if you really don't or you don't want to understand or deliberately hijack the discussions: we talk about banding not about noise. The pattern in that (chroma) noise (in my pics) is banding, not random. So, repeat yourself: banding!What I see in that is that the camera has adjusted the exposure between the two images, maybe because the second is on a corner so the headlights are hitting the side of the road thus brighter than when on the straight where they are illuminating the distance.
In the top image, the exposure has pushed the sensor to its sensitivity limit, maybe a bit beyond if you don't like that level of noise; on the second image the sensitivity (ISO) has been reduced so there is very little visible noise.
The two images show the compromise quite nicely, in the top there is little motion blur but a lot of noise, in the bottom there is little noise but more motion blur. Which is best? From the point of view of recording evidence, I think I would choose the top, if I wanted to make a movie then I would choose the bottom, but neither is the correct choice, just different.
Dont think so, i doubt everyone with this problem has led headlights and i feel the need to repeat myself, same car, same headlights, new firmware = banding/stripes or what they are called.Could the clever mirrored LEDs be causing the banding?
LED headlights in general can cause flickering in the picture due to the refresh rateSo how does that interact with the camera? Could the clever mirrored LEDs be causing the banding?
LED headlights in general can cause flickering in the picture due to the refresh rate
probably could be resolved, as you say though it's likely something that they would never give any consideration, just something we need to live with, for now at least, unless there's some other change in technologyIn theory, that problem could be eliminated if they adjust the PWM (pulse width modulation) properly when they design the headlights (or tailights) but often that seems to get overlooked because how these lights appear in digital video is not a consideration.
