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.

Camera struggles to focus

Hello,
I simply love my moto g but the same cannot be said about the camera. I find that the camera struggles to focus especially during close ups. I wonder if this is a problem with moto g camera module or should it be fixed via the next update? Tried Google camera also. Same problem.

Are you using the drag to focus (or tap to focus for google camera)? although I've just tested mine and mine is focusing and refocusing between distance and very close automatically no problem.
I did read on another thread that it focuses using differences between shapes so focusing on a plain uniform surface won't be very reliable.

What do you intend for "close"?
I take some photos at 25, 20, 15, 10 and 5 cm
The best distance is 25cm. Under this distance it can't focus properly.

Depends, mine can focus clearly all the way to ~6cm from the subject but the way the phone focuses it requires a definite 'hard contrast area' to focus on, although in your examples you do seem to have that (assuming you're trying to focus on the corner of the object above), if you try to focus on an area without much 'change' in the surface it won't focus.

Could you share a pic with 6cm focus please?

I still sincerely hope they fix the camera in the upcoming update. The camera on the moto g is a major let down despite being an improvement over the previous generation in terms of resoultion.

I only said approx 6cm, if you see the actual focus is just past 6cm and from testing earlier it will reliably focus at 7cm providing the light is good. You need plenty of light and hard edges for it to focus properly and you have to put the auto/manual focus directly on the hard edge for it to focus.

Thanks , yep I use the stock camera I've just updated to the new version and the results are the same, I have Google Camera installed for photospheres but don't use it otherwise.

I have copied your method, this is my best result so far: https://lh4.googleusercontent.com/-...cqJYQ/w643-h857-no/IMG_20141026_221648051.jpg

I have the same problem............

Just got this for my wife to.replace her old iPhone 4S. So far she is very unimpressed by the camera quality and the lack of focus accross the room. As it shifts through focal lengths it can get a crisp pictire but autofocus never stops at the right spot.
*edit* just purchased Camera FV-5. Had to boost the contrast and saturation in the app, but focusing is way better.

I too have this problem, I sometimes need to quickly take pictures of a page in a book for a quote, and the camera simply won't focus on the text at all. The moto g turbo used to do a great job, I thought I was getting an upgrade, but the g 4 plus camera focus on close objects and text is horrendous. Do you think an update will fix it?

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?

X-Ray on P40 Pro front camera

After the presentation of the One Plus 8 Pro and its x-ray feature, I have seen that other phones such as the Xiaomi Mi 8 and the Pocophone F1 have the same feature through an app, thanks to its front IR camera. Given that this Huawei P40 Pro has a front IR camera, could it have a similar feature?

I hope there will be an application for P40 Pro?

How did you do this?

So here's the magic: You need on external aid, namely an infrared filter for any kind of DSLR or similar cameras.
You'll easily find such filters at Amazon or other online sellers, eBay and the like.
Quite often, there are sets of IR filters with different wavelengths. Everything above 720 nm is less interesting as these kinds of filters result in pure black-and-white images, without any hint of interesting colors.
If you find a single one, go for a 720 nm filter, this is a kind of standard, providing full infrared coverage plus some residual colors making for nice effects like yellow or orange trees and a deep blue sky.
For my pictures, I used a 720 nm filter by "Neewer", a supplyer of cheap but still usable optics accessories. It makes no sense heading for the "quality" filters from "Hoya" and the like: optical quality is a tiny bit better, but it won't make any difference with our P40 Pro. I also use the cheap Neewer filter with my Fujifilm X-T20 (Fujifilm cameras are also quite sensitive to infrared light), with great success.
After you got your filter: You need bright sunlight and a subject with grass and/or leaf trees - these provide the best effects as they appear white in the photo.
Just hold or stick the filter in front of your cameras, make sure there's as less residual light as possible reaching the lenses, also never shoot against the sun (will lead to strong lens flares) ruining the picture.
Focusing is a bit difficult and slow, but manageable. Try to use ISO values up to 800 to lower the longer exposure time needed for infrared shots, still try to keep the ISO as low as possible. The higher the ISO, the more picture noise the sensors produce.
Take care of correct white balance while postprocessing the pictures, the sky should be reddish, grass and foliage should appear bluish-grey. That's the right starting point for IR pictures with some color accents.
If you wish to go for pure black and white pictures, just convert the picture into black and white.
For getting a deep blue sky and yellow foliage, you need to swap two color channels, red and blue.
For everything else, just watch some YouTube videos dealing with infrared photos, you'll find real plenty. Try keywords like "affinity photo infrared" or "infrared photo postprocessing".
If you need specific help, just ask here.

The phone has an IR Depth sensor, not a IR camera.

I think that the rear camera has an IR depth sensor, the ToF; but according to some reviews:
"For selfie shooters, the new model offers a dual-camera setup on the front, with the main camera using a 32MP 1/2.74-inch sensor and a 26mm-equivalent lens with f/2.2 aperture. Further, it uses information captured by a secondary infrared (IR) camera for depth sensing in bokeh mode and to support the autofocus and very low light face recognition"
I expected that P40Pro front camera works like as Xiaomi Pocophone and Mi8.
PD: to try the ToF camera download from Aptoide de ToF Viewer apk (0.4.2 version), works fine!

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
