Polaris camera tweak

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..

A Click like sound when autofocusing or exiting camera?

Hi
Anyone experiencing a low click like sound when trying to set the focus or when exiting camera on HD2? I am not talking anything about the shutter sound, this is something different. Not all times I can hear this, but for sure at some instances when setting the focus.
Thanks

Yes, I think it has something to do with the lens aperture. It decreases or increases in its range to compensate the image exposure to light...I guess that's normal behavior for a digital camera, even if inside a cellphone..
Since it also happens when zooming, I'm pretty sure it's the lens "mechanical" movement..

It's the focus lens being released to its "infinity" end position. It's most likely spring-loaded, and it hits the end point when control is released.

yup, anyone with experience of compact igital cameras knows that's a pretty normal thing
What's strange tho, is that I often/always get a very fast flash discharge blink when going from preview mode back to camera mode, or something... don't understand why that happens

xperia x10 Video Camera light OFF switch

I know where the option to shut off the light for the Video recording is but it doesn't shut off. My question is: is there of shutting off the light when i am recording a video on my phone? Maybe and app perhaps? or a way of deleting the setting in video mode? or a work around? anything? Its annoying when the option is there for it to shut off and it doesn't work. Its the same for my gf's xperia x10 phone too, it didn't work for 1.6 after the small update in summer and now it was fixed either with the bigger update. help please?

Take out the phone battery and re-insert. Hope this will solve the problem.

Yes, i have rebooted my cell phone several times. Thanks for trying to help out.

I also have this problem, the video light stays on despite the setting saying "Off".
Using 2.1.

search for xperia x10 flash light on market, it should work

Its on a low brightness. Just a privacy thing so other people know its recording. Kinda like the red light on most cameras

Oh really? thats too bad, i dont need the like all the time on, it kills my battery faster. I know before the update it used to be able to shut off once the setting was set on "OFF" mode. Ps other phones have the capability to record and have no light at all whats so ever. I dont think its a privacy issue

I agree with AssyrianBLOOD, it's a privacy issue. And don't worry about your battery life, HD video recording will kill it way faster. (For me, Battery life on 2.1 absolutely sucks )

The amount of battery life that an LED takes is so pathetically small that it shouldn't affect anything.
Every phone I've owned has had some sort of light to indicate recording as a privacy measure.

Is it something the manufacture imposed or government regulation? Because i know for a fact not every recording device (smartphones/ipod touch) has a LED or any indicator when you are recording. Secondly, the off setting used to work when x10 originally came out until the so called privacy issue came up. I want to know of a way of shutting it off without trying to cover it. I know HD also drains the battery faster but i am not making HD videos here, i'm making youtube videos for my faceboook and i though my phone does a good enough job. I just dont like the light setting having an OFF setting NOT working. If its a privacy issue than why have the setting to switch it off in the first place?

hey.. Sorry for hijacking the thread
I just came up with a thought.
The photo light does two levels of brightness as we know i.e Low brightness as a privacy feature while recording video and high brightness while switched on manually.
Is it possible(when the 2.1 source is released) that we can make a module to further increase power to the led to make it glow brighter so that we can actually use it as a led flash?? Just a thought
cheers
chetan

I just want to know if there is any of shutting it off thats it. You can hijack all you want once i get my answer ill move on. Im sure someone here knows how to shut off by some means thst doesnt require covering it.

[Q] LG G2 D802 Camera issue

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.

Flash darkens photos?

Anyone else observing that when they take a pic with the flash on in "medium" light conditions, the photo comes out actually darker than if the flash wasn't even used?
I swear the timing of the flash is bad on my S5. When I tap the button to shoot the photo, the flash turns on and the image on the screen looks bright and good. But then I think the photo is actually taken a split second later after the flash has turned off, and the photo that gets taken is dark as hell. I think I've tried all the combination of settings in the default S5 camera app, and nothing helps.

I haven't seen this with my S5. Unfortunately you didn't elaborate on your camera settings, camera version or other crucial details.
At a guess, and it is only speculation since we don't have your details, you are expecting the flash to act like a fill flash. When the auto mode (which is probably what you are using) probably uses the flash in a conventional manner i.e. a fixed shutter speed (or limited shutter speed range). There are good reasons for that, but the net effect if the subject is outside of the flash range is that little of the flash is reflected back and the (presumably) higher shutter speed lets less total light in resulting in a darker picture.
You can test that thesis by taking some pictures of a subject that is very close to the camera. If the problem goes away with close subjects that implies that the problem is an artifact of using flash for a subject that is too distant for the flash to work with. No flash can work at an unlimited distance which is why people using a flash in a stadium when they are 75 meters from a subject is silly. In this case, flash mode simply isn't appropriate to the situation you are using it in and you'd be farther ahead to use a slower shutter speed, without flash.
It's highly unlikely that a bug would see the shutter opening after the flash.
.

It happens with literally *every* combination of the settings in the camera app (with flash set to "on"). Auto mode, beauty face mode... actually, are there any other modes that I'd use to take a picture of something 3 feet away in a darkish room? I have panorama, "shot & more", virtual tour... those wouldn't be right, correct? So both beauty face and auto, with all the combination of settings... hdr on/off, stabilization on/off, iso at auto and all four "manual" options, all three metering modes... nothing makes a difference.
The problem is the same all the times -- it's not just that the non "subject" areas are dark -- the whole image is dark, just like if you turned off the light in a room and snapped a pic at the moment when the light was still on at 50% brightness as it's turning off. It's super annoying just because of how damn good the image looks on the screen when the photo is being taken... it even seems to "snap" the shot at the right time... the shutter sound goes off and the little border animation happens when the pic is nice and bright. Then I open the actual image and it's garbage.
I was hoping someone might know of some setting in a config file somewhere for a delay between when the flash is triggered and when the camera attempts to capture the image, and that maybe mine got changed somehow to a larger than optimal value.
My wife has an s5, I'll have to test with hers and see if it suffers from the same problem.

Long story short: the camera is using a fast exposure time to keep the subject from being "blown out", i.e. overexposed, when the flash is used. That means that the foreground is going to be sharper but anything in the background will be lost in darkness if the ambient lighting is low. When you leave the flash off, the camera will use a longer exposure time (or shutter speed, if you will) to allow enough light, which also lets more of the background be seen in the picture.
Another thing to consider is that if your screen is set for auto brightness control, you will not have the same brightness when viewing the gallery pictures that you will when looking at the camera view. The camera view is full brightness at all times, but if you're viewing the pictures that you took in the gallery, screen brightness will drop down according to ambient lighting. Photos definitely look dark if you're looking at the gallery by lamp light.

That's interesting stuff, but doesn't really apply to the problem I described (at least the first part... the screen brightness setting stuff is potentially related, but isn't in my case). The exposure time is fine, it's just **when** the exposure starts that is the problem... a little too late, IMO. Really wish there was a way to adjust when it takes the photo in relation to when the flash is fired.
The foreground objects aren't lit up at all. No difference between foreground and background. Sometimes, I'm taking a picture of a t-shirt laying on a flat surface from 2 feet away. Without a flash it looks pretty good, but it's a little dark so I decide to try the flash to see if it'll lighten it up a bit. Instead, it makes it look like I turned out half the lights in the room.... way darker than no flash.

Same here, three friends of mine too.

I'm having the same problem s5 neo

I just figured out how to correct the pics from coming out dark. Go into camera-settings-exposure value-slide to the right to 2.5 or more.My pics come out fine now. Indoor light normal daylight.( with flash off.) I will know more in other settings (places ,situations )if it needs to be tweaked again.

no problems here
my settings are AUTO MODE
flash AUTO
no effets at all
and still i get good shots in night

Power/current draw issue?
Mine was doing this, and I noticed the first flash (ranging) was fine, but the second flash (to illuminate the image when taken) was much weaker. Whilst plugged into charge, repeated low light experiment, and the low light flash illuminated image was fine!! Maybe battery on its way out?
