Hi folks...probably a simple fix but asking .....for help.

Camera is mounted slightly too high and just misses wiper arc so there is water and dirt in front of it, to start with. But I noticed the images "flares" when passing under street lamps. This "flare" really degrades the image quality. Speaking of which I had it set to 2K. I've now set it back to 4K. Of course the water and dirt isn't helping .

So any ideas. Play with Evaluation metering? I cannot really angle the lens down as it'll just be mostly bonnet. I do know I need to lower the camera so its inside the wiper arc.

Additionally......I noticed the head unit display reflected off the windscreen into the camera image at night! Urgh! So lowering the lens angle will make this worse...maybe not maybe it will now miss it due to incident angle?

The rear image is fine. Attacked are some still showing the issue. No need to try load a big video file.

Any ideas.....or "you fool"...appreciated

Many thanks

Yeah the blooming of street lights are a common problem, if the windscreen are dirty that just make it worse.
Not much to do about such things today with the hardware in use
 
Many thanks Kamkar. I'll try a small "light shroud" over the to to see if it reduces it.

Yes it needs to be lowered into the wiper arc.
cheers

Idk if this is what youre asking, but the reason the 1st and 3rd image have a washed out gray picture is because you have WDR turned on. As the picture gets darker the WDR compensates and improves low light image quality. Simply turn WDR off if you dont want this "flashing". The caveat is the image exposure will stay on the darker tone as you pass over the lamps.

the second thing im noticing is the blooming of the lights. The "orb" around the lights is called bloom. This will happen with light refracting off either the lens or the windshield if they are dirty.
 
Thanks MMS...yes the lens is not thru the windscreen wiper arc...its slightly too high so its a dirty area indeed! I will move it down.

God point on WDR...but I'll try one at a time to see the changes

Many thanks
