Hi, I recently got a polaris and I'm loving (most of) it.
One thing I realy hate, is the way the fps goes way down with video's in low light conditions. I searched trough the registry myself and found some values to increase the fps of video's a bit, but the moment the light conditions change, it get's crappy again.
Is there some way to fix the light condition so it doesn't adjust while making a video?
I love going to parties and I'd like to make some video's. There is enough light there to make a video, but because of the strobing of the lights, the camera thinks there isn't any light and goes to crapy fps mode trying to...I don't even know why it does it, longer shutter timing maybe or something. So I want to find a way to fix the fps, light mode and shutter timing. If that is possible.
Or I would be hapy with any other info you guys can give me on this matter to improve the camera.
In case someone would like to change some camera settings:
HKLM\software\HTC\camera
In the recparam, you can set the framerate at witch the video records. It can handle a bit more then the default setting. The default is 15, I got mine set at 25 witch works fine. The display isn't able to keep up while recording, but the recording itself looks fine on the pc while playing back.
If anybody can help out more with tweaking the camera more, I'd love it!
I'm especialy looking for the light metering settings that change the fps when the light changes.
Clicky!
Welcome ^_^
cellshadow mean welcome to Camera & Graphic issues Polaris club
to get some information about it you can read this loooooong thread

any way, I will teach you a trick to get full performance from Camera and you can shot video if you have enough light
start camera, hide the lens by your hand, press the power button, wait for 5 or 8 sec, press the power button again, remove your hand from up the lens
now you can shot video in 25 frame/sec
if you get any new tweak or trick for camera please post here
Secoseco, your trick really works! The illumination auto-adjust seems to be not processing the image when I follow your steps, so the image is just captured, a bit darker, but almost realtime!
Is there any official fix on this?
XD
Zomg the trick really works. thats nice.

waiting for some one to analysis this trick to solve the camera issue
may be shutter speed, or white balance
Well I know a little bit about imaging and stuff.
Camera's have different ways to alter the amount of light in a recoring. They can change ISO values (higher value means more responsive to light) wich would not affect the shutter time.
The sensor in a camera (video or photo) needs a certain amount of light before it can register the image projected on it. The better the sensor, the higher quality and options. If you got a lesser quality, like in most cell phone camera's, you don't have to many options for changing the sensivity of the sensor. Meaning, if you want more light projected on your sensor in low light conditions, you need a higher shutter time. This is for both video and photo, the way the finer mechanics work differ, but a video is nothing more then a series of photo's put together. Now when the camera, or in our case, our lovely polaris, notices there isn't much light, it sets the shutter speed (for photo's) longer (that's why photo's in low light get blurry) and the fps (for video) lower (giving the sensor more time to register the light for each frame).
How the trick from secoseco works, I do not know, but it works like a charm. It has to be some sort of bug for it to work this way.
Now I know about the wm6.1 that is supposed to increase video preformance, I have not installed it yet. But the thing I want to fix is the way the camera measures the light and addapts to it. There are so many settings, there just has to be one that controls the way camera settings change in different light sircumstances. Because in good light, and with the trick of secoseco, the fps is just fine and the video is good quality. But the moment the light value gets lower, the fps drops waaay down and the video gets crapy. Wich isn't always needed, like at a party when there is enough strobing light to get a good video, but when the fps is still way down.
I want to either lock the fps, shutter time or disable the light measuring or any other thing that can cause the current proformance of video's in low light conditions.
I'll try looking for myself when I'm not working, but I'm new to this phone, so if people come across anything that can help, it would be great. Registry locations of stuff related to the camera, files that control the camera, anything.
Yeah that trick has been around for awhile. However the moment you point the camera to a bright light source it resets again and will lag in low light conditions.

what is the benefit to point the camera to the light source during picturing ?
There is no benefit in intentionally pointing it at a light source. But if it so happens as you're trying to take a picture or video of something and you do happen to get too much light it will lag again.
Problem
I have problems with Send/Receive email client on me Polaris,not working. Internet connections is ok, help me pls. Sorry for me english.
Thanks secoseco
For real. Thanks secoseco. This trick really works
Wow this trick works like a charm! Many thanks goes to you secoseco!
I think it has something to do with whitebalance because changing it in low light conditions will give me some more fps... but it is still not enough for taking videos!
Too bad that the picture quality sometimes gets worse after using the trick.
Thanks a Million it workssssssssssssssssss..
I've just bought a Touch 3G and as far as I can tell the Auto setting for the Backlight doesn't seem to do anything. As my last phone (P3300) didn't have this, what should I be expecting to happen? I've tried putting a finger over what I think is the sensor (right hand "LED", beside speaker) and nothing changes.
Thanks, W.
Did you set Auto adjust backlight in system menu?
Imho it is a really subtle effect. You can see it a bit when holding the light sensor (right to the speaker) to a bright light source. The display then gets a little bit brighter.
If you would like to increase the effect or customize the stepping, try g-light ( http://www.ageye.de/index.php?s=glight/about ), it lets you set specific values for each reported value from the sensor, and set the polling interval
Jade auto adjust is poor
I had the diamond prior to purchasing the jade. The diamond auto light adjust was very noticeable compared to the jade. In fact I didn't think the Jade even had a light sensor until one of the other users pointed it out.
After a little research I found this thread. http://forum.xda-developers.com/showthread.php?t=450318
I used it on my Jade and it works great. One of my problems with the diamond was the fact that the light would not automatically dim enough in low light conditions.
Thanks for the link. Now using G-Light which works pretty well. Not perfect as its sometimes a bit erratic but certainly makes better use of the light-sensor than HTC!
Hi all,
I have a visual disorder known as PMA ( Persistent Migraine Aura). Simpy put, my vision is extremely sensitive to all light forms.
The S4 has really bad backlight flicker, especially in low conditions I can see the flicker. It's really horrible for me as I see it more than the average person would. I couldn't believe it had such prominent flickering from the backlight LED's (low refresh rate?) when I first got my phone; I recently sold my Laptop as it had a poor LED backlight panel.
Now to my question: is there any rom out there that reduces this? Any way of reducing this flicker (increase refresh rate)? It's really making me considering selling the phone
Any help will be appreciated.
Hello guys,
Can you tell me if you have the same issue with your S5 in low light condition ?
I don't know why in the middle the picture is normal and the color and the quality changes in the corners..?
Any solution?

Hello to anyone who is reading this.
I am on the T-Mobile D80130b 5.0.1 lollipop stock ROM. I've noticed (even before I updated) the camera and video recording sometimes changes to a yellow hue on the image/video. Mainly does it in slightly less than adequate lighting but the amount of light is still enough to take a good picture because it will be normal and I can see the picture looks fine but it changes to yellow and when I take the photo and look at it it's yellow. Any ideas?
