camera question..

hi there. recently i notice that there are green dotss and blue dotss somewhere on the picture taken from my camera.. does this mean that there are dead pixels?? or my camera become faulty??
is there anywhere to clear all the dots tat are on the picture??
sorry my english is not so good
:shock:

i had uploaded a photo that had been taken from my camera..
please have a look, there are lotsa green dots n blue dot somewhere on the picture..
how can i solve this problem??

I've got green and red dots also on my camera. Even had it on my only previous faulty device too.

Apparently I think this happens for everyone's XDA IIi or equivalent device. Is there any experts out there who can explain the cause?

:lol:
thats called Sensor Noise! because the photo sensor on mobile devices is so small if you try and take a picture in a dark environment you'll get noise!
try taking a pic in an environment with plenty of light :wink:
if you want a decent picture spend a few $$ on a decent camera

i had try out taking a picture somewhere brighter, but the result still same.. here's the picture i had taken.
by the way, how can i upgrade my xdaIIi's camera to the type of camera u mention ?? upgrade it from o2 service department ??
thankss

You can't upgrade the internal camera, there are no direct replacements. If you look at the Hi-res images I got of the Alpine you'll see the sort of size and shape of camera required and I very much doubt there'll be others the same or similar shape/size. If there are then you need to add the data ribbon to connect it.
Overall go to an Elec store and buy a dedicated camera.

I don't agree. Motorola V3 has a camera as small as XDAIIi and the pictures are awesome. Lenses are a determinant factor in quality. I personaly have a Canon DC20 that takes wonderfull photos but I would like to get better photos with my XDAIIi. Why not get better results wiyh ours devices? Converging functions in one device is helpfull to mobile professionals. BTW, tweaking the camera settings in registry makes the photos much better. See this forum for more information.

I think that there is no problem on your camara. note that if you want to have a good picture you must chose the best index light in setting of the camara for example; ambience: night or flourescent... and the cature mode, cature size..

The camera isnt that good but you are never going to get great pics from a lens that size and indoor pics are always going to be grainy without a flash tho you should be getting better pics than those you have so far

Do a search for AtekSoft's CoolCamera. It allows quite a few more options than the default. There may be better camera replacement software out there, but I havn't found it yet.

Ateksoft is the one most Cooooooooool Camera software.....

From what I understand, O2 included a camera 'upgrade' in their extrom (which installs whenever you hard reset), which actually makes the camera quality WORSE. I've not tested it myself, as I'm quite happy with my phone setup as it is and really don't want to hard reset AGAIN, but some users report that flashing their device with the firmware which doesn't include this camera upgrade makes their camera quality better.
Also, you have to bear in mind that pretty much all cameras use cheap and nasty CMOS sensor technology (what low-quality webcams use) - the resolution and light sensitivity of CMOS technology is REALLY poor compared to CCD, but CCD tech is much more expensive and sucks up more battery power (hence CMOS technology being more widespread in the mobile industry).
Better quality cameras are starting to appear, and the quality of the k750i camera continues to astound me when I see my friends' photos. It won't be long though, I remember seeing articles about lenses made with a tiny suspension of water inbetween two nanometre-thick layers of plastic, to which an electric current could be applied to make the water change shape, acting as an optical lens... This kind of technology will drastically increase the quality and cost-effectiveness of higher-end portable, miniature camera technology, and I can't wait until it becomes widespread.

Quick question. Please read :X

Ok, So the camera's 3.2 mega pixel and the video recorder records pretty low res.
Would it be possible to edit the recorder so that it can record higher res/better quality?

Or is there any apps or console commands to change this

Unfortunatly the camera is very poor and nothing will fix it. Thats all there is too it.

Ok, Well that didn't answer my question.
Any the camera isn't poor it works great, Its a bit crappy in low light but still it looks awesome and better then a 5mp camera phone from samsung.

I actually have to agree with this as I've had the G600 and that camera SUCKED no matter what PhoneArena says. I noticed i would only use the G1 for pictures so i got rid of the 600

I took a picture of my eye and then shooped the hell outta it. (I added alot of the spots and wrinkles :X)
This is a resized/croped version, Hell you can see the g1 reflection in my eye.

Ok you must not be able to read.
I'm not asking about quality of the camera.
Im asking if its at all possible to make video RECORDING better or higher res.
And what do you mean by nice fake?
If ur implying the pictures fake, Its not at all fake and was taken by my g1.

It depends alot on bandwidth of memory in the device. I dont know if it is possible right now to make a better/higer quality video recorder. If Google creates API's that take advantage of the full potential of the graphics chips we may get a better camcorder app.

I updated to hero and it seems to have a bit better video recording
but thats because of the codec it uses.

Seriously, read the freaking thread before saying something stupid.
As for the question, I'm sure a developer could create a new app for higher resolution video recorder because it has been done on other devices. Try requesting it here http://forum.xda-developers.com/showthread.php?t=446769

Thanks.

post removed, misunderstood question

No, and the reason is:
A still camera has a longer exposure time and can dedicate more light overtime for each picture. A video has to a expose an image 30 times a second, so in order to expose properly the camera must take many pixels from the ccd and group them together as 1 pixel reducing image size for video. (I could be done by reducing FPS, but that will only go so far.)
And there is also issues with video format standards and the G1 ability to play back video to consider as well.

Heck, even my Canon 5D Mark II can only record video at 1/10th of the resolution it captures still images at. It does video at 1920x1080 or 2,073,600 pixels, whereas still images are captured at 5616x3744 or 21,026,304 pixels.
I think people expect far too much from a phone that has a camera that probably cost $15 to manufacture (the camera part - not the whole phone).

No I dont exspect it to do better i just wondering if it could.

Crappy close up / zoomed i n camera quality?

So I love my nexus 6 and the quality of the camera taking normal distance shot is great but what not so great, at least for me, is the crappy quality of photos taken up close or zoomed in.
If I try to take a picture up close, it's blurry and doesn't focus. If I try to take a picture from a distance and try to zoom in to focus, it doesn't work either.
There are many circumstances that I need up close pictures taken such as when I use my fitnesspal app where I have to take shots of barcodes to add to my nutrition log. I also work In IT and use my phone to take pictures of the back of equipment in tight spaces such as the server room.
Does anyone else experience what I am experiencing with close up pictures not focusing?

Bump?

I wouldn't bump it if I were you. IMO, the people who own the device will most likely disagree with you to justify their purchase or haters will spread hate and will end up comparing it with other devices causing flame war.

first off, you have to stay back a few more inches on the nexus 6, about 7 inches or so. and dont zoom in, that automatically reduces the quality. you can crop it lateer, much better than zooming in. besides that, you have to touch to focus. tap where you would like the camera to focus, and thats where itll "focus"(quality will be better there)

I think the camera is pretty decent personally, it's not like the best on the market or anything. It surely is far from the worst though.

Yeah as mentioned, zoomed in pictures are always going to be crap. We don't have optical zoom, we have digital zoom. All digital zoom does is crop the image grabbed from the sensor in the middle and then blow it back up to the same size. You can reproduce this yourself in Microsoft Paint for example.
See below for example
Download this 500x450 image: http://www.prime-junta.net/pont/img/How_to/ha_Testing_lenses/high_acc_low_res.jpg
Open it in paint like this:

Select a part of the picture in the middle...
Crop it...
Set the image size back to the original (or as close as you can get)...
Voila, poor quality image..

I'm a hobbyist photographer, have a degree in video production and work for a university doing this stuff. I will be honest that I have just gotten the Nexus 6 and haven't had a chance to really put the camera through its paces yet. But I can provide some general information that might help you understand what could be going on.
First of all, every lens has a minimum focusing distance. This is going to vary for each lens/camera. If the lens is closer to the object than this minimum focusing distance, then it can't find focus - the pieces of glass just don't have the room to move to the right place to focus. This is why people buy Macro lenses - they can focus a lot closer than other lenses. Now, I'm not saying buy a Macro lens. I'm just bringing that up for reference. There are Macro lenses you can buy for smartphones, but I never used any so I can't comment on what's good or if they're worth it. But this could help if it's that important to you. The only thing I will caution you with if you DO go for a macro lens is that these tend to provide a very shallow depth of field (blurry background/foreground is exaggerated). In a nutshell, this phone may not be able to focus on things very close.
With regards to zooming in - there's no real zoom on this camera or any released prior. Some new phones demonstrated at CES (or at least one) has a real zoom built in. What I mean is optical zoom. Optical zoom is the actual mechanical movement of the lens to zoom in on objects. So far, there has only been digital zoom. Digital zoom is no different than cropping. The problem with this is we have a fixed number of pixels for the image. When we crop or digitally zoom, we throw away a chunk of pixels on 3 or 4 of the sides we're zooming/cropping to and enlarging the remaining pixels. The more we zoom or crop, the lower the image quality becomes.
If you're scanning barcodes, I'd say perhaps you're doing it wrong. Most apps don't need to see this very close - it doesn't need to fill the entire screen. You can also indicate where to focus by tapping the screen what to focus on - this will help.

I've tried taking pictures close and from a distance with zoom. I just can't get it to focus quick enough to reaD barcodes.
Previous to my nexus 6 I was able to use my nexus 5 and iPhone 5s with ease. I literally would pull up the app, scan the barcode up close and it would read it instantly.

I'm having the same issue. Even without digital zoom, any subject within about a foot and a half are fairly to completely blurry, getting worse the closer it gets. I understand lenses have limits with regard to focal distances, but as the phone attempts to focus, the subject becomes crystal clear once or twice before the autofocus settles on a blurry setting. So far I've tried clearing the cache and data and restoring the camera app to the factory settings. I've also tried a different camera app, but the same issue was still present.

why autofocus? itll focus on an average focus. if you want it focused right, then touch to focus.

Same problem happens with touch focus and average focus.

Low light

At the club, at the bar, or just in your mom's basement, nighttime is when you come out to play. Rate this thread to express how the LG Nexus 5X's camera performs when no or low light is present. A higher rating indicates that the camera sensor "sees" lots of light in dim conditions, and that the resulting photos have minimal noise. A higher rating also indicates that when the flash fires, the resulting photo is evenly-lit without any bright spots.
Then, drop a comment if you have anything to add!

Good but not great.

Can confirm, the camera performs terrible, when no light is present. The pictures are black with a lot of noise.
I hope they fix this in the next update.

In dim light situations the camera is good...
Few days ago I was at one place and lighting was about 30% out of 100 and 5X performed good, alghough photos had some noise, but they were not dark, which isn't bad.

Excellent for a phone, not much more to say.

How is this getting such bad rep and review compare to 6P when they both have exactly the same camera and take exactly the same quality pictures?

I couldn't disagree more with most of the people here. I have owned a G4, Note 5 MXPE and this camera ranks as follows in low light. 1-G4, 2-3 - Note 5 and 5X (about as even as it gets) MXPE-4

Are you guys kidding? The low light pictures are nothing short of amazing. And I own a 1.8 35mm (which is better, obviously, but comparable).

This. It's a $400 cell phone camera that compares well with $600+ device's cameras.

The sensor and lens are excellent for a phone. From about ISO 400, it resolves more detail than my Lumia 930, which uses a sensor which is only very slightly smaller but much higher resolution. It also has better dynamic range across the board. HDR+ is particularly impressive compared to the HDR modes on the other devices I've used. However, it really could have done with an image stabilizer to mitigate motion blur on longer exposures. I fairly consistently get less blur in low light with the Lumia and even my old G2, both of which have OIS.

Exceptional

Lowlight pictures are really amazing...
Nexus 5X+ Nova+Root

No issues here.

Low light condition front camera without HDR+ is like taking a picture to nothing but black. With HDR+ activated is really awesome what it can do. Obviously is not like having a flash on front camera but it gets much better.
On rear camera without flash and HDR+ is much the same result as the front camera. With flash photos are really good quality and smooth.

can you guys share photos taken on low light conditions?

I have 3 phones atm - Note 20 Ultra, P30 Pro (global), and Xiaomi Mi Note 9S w/GCAM. I never imagined the N20U would be able to match the camera quality of Mi Note 9S w/ GCAM, however after taking some daytime and also low light photography, N20U takes the best pics out of all three of my phones. Even night mode. However, I don't like the all white balance, and even though you can change that in Pro Mode, when you take pictures in Auto Mode, I hate the color that all Samsung phones give out, and prefer iPhones and Huawei phone color temperatures / hues. Also, there were certain scenarios (although not many), where the P30 Pro or the Note 9S w/GCAM took better pics, but that's expected. N20U took better pics than both of the other phones 75-90% of the time, even night time photography

it's all subjective. You like it 75-90% of the time. It doesn't mean 75-90% of everyone else will like it 75-90% of the time. With camera modules basically being made all by Sony or Samsung, they all look the same. besides, I haven't known anyone to print their pics. it's being compressed or filtered onto VSCO or IG anyway does it really matter? Just take your picture and be happy with it. Unless you have a 99 dollar tracphone, it's the same quality...and even if you do have that $99 tracphone, your grandma can't tell what phone it was taken on when you post it on fb.

Software & image processing makes an immense difference - hence the constant desperation for broken GCam ports.
As a S20 Ultra owner - that phone has supposedly great hardware but has demonstrably awful image processing in a myriad of everyday situations (it's still way below par compared to its peers, after all the updates).
-----
On topic, the processing on the Note 20 Ultra is significantly better than my S20U in basically every scenario & camera mode I tried it in, including Low Light (my S20U's photos look like watercolor messes in comparison). The S20U only takes passable images with bright sunlight or sunlight-equivalent indoor lights. It fails miserably at processing images the dimmer the lighting gets, which I didn't find to be a problem on the S20U out-of-the-gate on Auto mode.
Can they bring the software updates to the S20U?

The Note 20 Ultra camera is identical to the S20 Ultra.
Low light on the S20 Ultra is better.
Clearly there needs to be an update for the Note 20 Ultra.
And like the S20 Ultra, it's impossible to take a picture of a document and have clear text across the frame.
Hopefully they go back to the drawing board for the S30 and choose a different sensor/lens combo.
The iPhone 12 camera is going to blow this one away as the 11 Pro is already better.

auto low light example that's lit by LEDs. Not bad.

Actually even with same cameras and sensors, you can have Vastly different output. Just look at Pixel phones, alot of other manufacturers use the same exact sensor however its the software engineering that makes pixel phones take great pics. You just sound like an argumentative person, I was just providing my personal experience, and never mentioned that other people's experience would be the same
