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 have a hd2 tmobileUS rom version 2.13 and radio 2.10
when i take pictures at night and the flash kicks in i get this green hue in the picture..
ive seen the fix for the older version but it was for pink dot in the middle... i dont have that problem
can anyone send me to the right link to fix the green hue?
52 views and no one can reply?!?!?!?
For photography to work you need adequate illumination and a sensor medium that can capture that light at the correct level across the visible light spectrum. The medium needs to be exposed to the light for the correct duration and the light source needs to be bright enough and illuminate the scene for an adequate length of time. There are significant limitations in designing a phone camera to work this way and achieve a ballance and if you look elsewhere you will see that many phone cameras have this issue.
I don't think there is an actual "fix" and your choices boil down to trying different camera settings or downloading your photo's to a PC and tidying them up with Photoshop or similar. Try changing the camera settings from "Auto" to bright light, fluorescent etc. and take a picture of the same scene with each setting and determine which one you like best. Aslo, ensure you have explored the obvious and that there is no obstruction (case, plastic film, dirt) to either the flash or the lens.

Hi Guys,
With the torch app you can increase the light power ? (high voltage?) is it possible to decrease it too?
I take pictures and the flash is far too powerful and would like a setting or percentage to decrease it?
If its possible per-se I'll look into the code and have a play?
Cheers, Sarkie

Hmm, the flash is never too powerful. What you want is to decrease your camera expose time or the iso-sensitivity.
In stock camera app, you have the settings button, choose exposure -1 or -2. You'll get what you hope for.
Today, for the first time, I've noticed that the N1 is adjusting the flash intensity. It seems to have 3 or 4 different levels, and while taking a photo, at the time of the auto focus, the led comes on at various intensities, and the best one is chosen.
I have never noticed it before (but I don't take many pictures.
Maybe it's a 2.2.1 feature. I am not sure.
Hi!
I'm having a problem with my camera and haven't seen a thread about this specific problem yet.
This only occurs on special light levels. I can adjust the brightness of the lights and if i go any brighter it dissapears and it also seem to dissapear if i go less bright. I haven't used the camera much but I don't see this on pictures i take in my livingroom or outside (it needs just the right brightness level to show). It occurs both on pictures and on video, but as it is easier to see on the video.
Does anyone have the same issue, or is it a thread that i've missed? I'd like to know if I should try to get a replacement or not.
Thanks!
Can't link as this is my first post, but here is the problem, and I hope I'm allowed to link like this (otherwise remove thread).

The problem you are talking about is the banding of horizontal lines? My guess is that as you adjust your lights it changes the frequency so that it is now causing the often noticed problem of when you take video of your tv monitor.. the shutter speed of the phone and the lights are oscillating.
This happens with all video cameras to a degree. Since the phone has less control over its settings i would suggest you just change your lighting until the problem goes away. Possibly changing the camera profile to something different could help but that just seems the wrong way to deal with the problem at this time.
I'm not sure if this is related to some interference in your ground to your lights or what, but hopefully my post will help you research it on the net or something positive.
Good luck.
hi there,
so my stock G2 stands on a desk looking with its cam somewhere, say being focused on a wall painting across the room. After a certain period of time the screen turns off. How do I tweak this time? Specifically, how do I increase it?
thank you,
