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
http://forum.xda-developers.com/showthread.php?t=359991
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..
hey guys, I wanna know what is the best manual settings you use with this phone
because in superior auto my photos become blury and not sharp
Depends on the circumstances, that's what manual means. Is what you want to capture bight? Use low ISO and fast shutter speed. Is it dark? Use high iso, slow shutter speed and a steady hand. The Scenes are basically Shutterspeed/Iso/Whitebalance presets adapted to a specific situation.
However, Superior auto photos should not be blurry. Either the phone or the picture are moving to much, or your phone has a defect.
I'm rooting my device then enabled cam2api on this device in order to get the ability to manually adjust the camera parameter setting (ISO, shutter speed, etc) and after the cam2api is enabled i got acces to the manual setting (i also verify this using Manual Camera Compatibility app and the test result showed that it worked)
I installed and try different camera app such as camera fv-5, dslr camera, etc (basically any camera app that has manual camera setting) and i found it when i set my shutter speed more then 5 second, if i take a picture it will freeze up the camera app (no matter what the app i use), though in the camera app i can set the shutter speed to maximum 10 second
My question :
1. Is this bug or hardware limitation?
2. Anyone know what is the maximum shutter speed for this device? (I'm planning for doing long exposure photography using this device camera)
3. Does anyone know the other minimum and maximum camera parameter from this device? (ISO, apperture)
Thanx for u'r answer
I have used Camera FV-5 Lite without root...it gave me shutter speed of upto 60 seconds...the camera would not freeze too....it's good but light streaks are not smooth....there is also a camera developer option if you click the red eye button several times...there in the manual user settings you can put manually 10000 milliseconds or 10 seconds...but in my 4Gb variant & .337 update it was only 340 milliseconds or 1/3 rd second...and a 6 GB variant with .326 update it was 500 milliseconds...and with 3Gb variants it's 10000 milliseconds or 10 seconds with latest update as I heard...ASUS phones are reacting differently in different variants and different updates..it seems that 3Gb variant is the strongest in camera department....it's funny and surprising.... I am attaching a photo taken with Cam FV-5 Lite and the manual settings comparison...moreover ISO of 4gb and 6 GB is upto 1550 whereas in 3Gb variant it is upto 1600. Please share your views. And ASUS I don't know what are you upto? In Hedge Camera in fireworks mode and 100 ISO it's giving decent slow shutter speed but not always..Alas I am also attaching a photo of hedge cam.
Hello! i have a question regarding the shutter speed of my oneplus 5. No matter whatever app i use or custom rom i flash, i cant set or control the shutter speed, neither with stock camera. Even if i set the shutter to 30 seconds the camera will take the pic in about 2/3 seconds max. I used to shot very cool pics at night with my Op3 (with resurrection remix) by controlling the shutter speed and when i bought this phone i thought i could have even done them better. Also the google camera by arnova doesnt work really good: a pink tint fully cover my pic taken with hdr+ activated. I guess this is normal because there is also the option to remove it but as the pink tint is gone a new black tint comes to cover the corners of the pics and the result is pretty weird, photos are so unreal. Anyone have any idea what's going on? i tried it all but i still have this issue, my priority is the shutter speed by the way
I noticed that in pro mode I have the ability to set 30 seconds shutter, however this is not possible in any third party apps, they all have a maximum of 15 seconds. The ISO however is limited to 3200 in pro mode but 6400 in third party apps. Is this intentional by OP or is my phone behaving strange? Can someone confirm?
I also am frustrated about not being able to set both manual iso and shutter speed simultaneously in pro mode, if I do, the shutter speed is ignored. I have reported this as a bug twice to OP but not received any response, so I assume it's either intended to be that way or it's a bug that no one else is experiencing. To be precise, it does work some times but only in specific settings which seems to be random and I'm unable to see a pattern. Can someone confirm this or is it just me?
First of all, you can reach 6400 ISO in pro mode if you set it in auto and your shutter is like 1/8000. Which brings me to the point of questioning your "settings".
Why would you want a 6400 ISO if you have a very long shutter like 30 seconds? That is pointless in itself. This is basic photography and I don't think you understand the correlation between the two.
Not being rude but you should probably learn the basics first before ranting because it seems to me the phone knows what it is doing based on the scenario I've given above. I also tried it and it doesn't "ignore" each other.
Correct me if I misunderstood your intention.

Hi, thanks for the response. The only thing you misunderstood was my intention.. I really don't want to rant, I just want help and to know if I am the only one with this problem or if someone can confirm that this is how it is set up or if I'm doing something wrong.. I do understand basic photography even though I'm not a pro, I studied two years of photography but didn't make it my profession (15 years ago so I might be rusty)
The problem isn't that I necessarily want 6400 iso and 30 seconds shutter, that would just create a white photo.. However, some times I want to raise the iso more instead of the shutter when for example taking a picture of my 1 year daughter sleeping beautifully in a darker room. She doesn't tend to lay completely still for 30 seconds so I might raise the iso and live with the grainyness. If I adjust the ISO but leave the shutter on automatic, the shutter will just take a quick black photo and won't compensate on its own, so I then I might want to set the shutter on manual as well, this will however not work. This is what I mean.. The shutter setting will be completely ignored. I'm not getting anywhere with this in the op camera app. It works fine in other 3rd party apps, that is why I'm assuming it is a bug or there's something I don't know and am doing wrong..
The problem with 3rd part apps is that I can't choose 30 second shutter, only a maximum of 15sec. I can get around by changing camera app ever time I need to but I'd rather have one app that works for everything if possible..

Thanks for the clarification but in order to help you out I did the test myself.
Setting 1:
ISO: 100
Shutter Speed: 2
Result: Basically a black photo
Setting 2:
ISO: 3200
Shutter Speed: 2
Result: Bright enough photo
Setting 3:
ISO: 3200
Shutter Speed: 5
Result: Blownout photo
Setting 4:
ISO: 100
Shutter Speed: 5
Result: Black photo with some light
Both on Manual Setting. The rest is auto.
So I guess what you want to do works. Didn't do the 30 cause it takes too much time.

Thanks! So I tried these exact settings and also tried several manual ISO levels with 8 seconds shutter. Every image was taken instantly, no 2 second, no 5 second and no 8 second shutter. The image results were based solely on the ISO level. So in other words, my phone is the problem since I'm unable to perform the exact tests you just did. Thanks for taking the time! I will now try to contact OP for the third time and see if I can get a response.
