i8000 camera autofocus worse than i900?

[Guest ray1234]

I own both the i8000 and i900 and I took some time comparing the camera of the two. I find the i8000's autofocus not as accurate as the i900. There are some photos that the focus mark turns green already but the focus is wrong.

There seems to be particularly a problem when face detection focus is used. I've tried many times where i8000 can detect the face and display a green mark on the face indicating focus is fixed, but the focus is not on the face. It is so bad that you can actually see on the screen that the picture must be out of focus, as everything is blur. This doesnt happen with i900, if it cannot find the focus on the face (mostly due to low light), then it simply will not display the green mark. The fact that i8000 displays the green mark while not actually fixing the focus is confusing.

Anyone else observe this? I'm starting to wonder if the autofocus hardware on my i8000 is broken...... however, at other times, it seems to be able to fix focus, so this is posing a great problem on the useability of the camera function

I think there have been a couple of hardware changes on the O2 compared to the i900 and.........not for the better.

Damn sammy for using the good reputation of the i900 to push the O2 but using worse parts just to get more profits.

Flash memory is slower, camera is of poorer quality (at least the software is or both), GPS is a toad.

My i8000 came with a faulty autofocus too - It will fail to focus at some distances. I managed to confirm it after borrowing a friend's i8000 to compare.

Samsung service centre changed the camera module, and it has been working fine since.

[Guest 2ngaw]

My fiancee and I both have O2. And I noticed my camera cannot focus at the center. the focus is usually on the far left side of the picture. During taking pics, it looks fine, but after snapping, you can really see that the focus is not at the center. So it's quite useless when using Smart Reader. I think I need to let Samsung change the camera module too. I was just surprised it is a commom problem with the O2.

[Guest ray1234]

for me, it's the consistency that's in question. I don't think my i8000 has problem focusing on certain distance, but it is just that it may get the right focus only 50% of the time...

[Guest ray1234]

ok, I did some more testings found that the autofocus does seem not to function well after initially focusing the first time. I find a strange way to make it work better. Only turn on the camera when you put your camera at the object you want to take photo, this way the camera will focus at the object once it is on, and then your object will be in focus.

If you turn on your camera while pointing somewhere else with different focus distance, the camera may not be able to focus back to your object afterwards. I've tried my new method and has since been able to fix focus every time..... strange !?!?

i have similar problem with my i8000: autofocus has issues when focusing for the first time. it stays focused at around 10 cm from lens, and there is no way to focus anything further. definitely, this is a software issue: if i close camera application, and then start it again, guess what... the camera works perfectly.

a long time has past since the last post... anyone found solution?

hi..i hope it is a software issue because i bought O2 in ASIA- Taiwan - official shop- but now i am in Europe and seems to have same problem with camera..with same fix.. turn on and when i see wrong focusing turn camera app off and then on again.. sometimes on 1st try, sometimes on 3rd try.. but confusing..because many times i found wrong quality of pictures at home PC- :P.. do you know if warranty is aplicable in Europe?.. or it is only sowtware issue?..how may i fix it forever?

i owned i900 before with amazing quality of Pics..

Strangely, I have none of the problems you have stated (I use GPS - google Maps+ Xtra and Papago; I use the camera - no issue with auto-focus or smile detection, but geo-tagging doesnt work in the newest HZHJC2 rom; flash memory is in fact quicker on my phone - MicroSDHC or internal flash? either way both of them are faster than the i-900 I used to own)

The only problems I have with the phone right now are 1) the occassional sluggishness with the Touchwiz 2.0 UI -including wigetplus (OK! I sort of have come to terms with this issue having played around with my cousin's HD2 and having experienced the same sluggishness with sense UI) - and 2) low RAM memory (actually, I get 68mb of free ram at start-up; if I flashed the newest eboot version (JC2 eboot instead of keeping IL2) I would have 73mb of free ram at start-up)

I don't experience other problems that other members on this forum have encountered. For example, people say the graphics on this phone are sh*t on this phone and it gets laggy running games. Well mine doesn't get laggy running games, even without having the FPU enabler turned on, games like Crayon Physics Deluxe still run very smoothly on my phone. Running FPU enabler basically just speeds up loading time (loading time definitely is snappier with FPU on but in terms of game flow, I'd say it's just about the same)

My I8000 has issues with camera as well, sometimes when doing AF it produces strange noise when held at some angle, also picture quality is poor i think which was confirmed by pocketnow review. maybe its the JPEG encoding? is there a way to get a raw image from the camera?

I tried the latest JG5 firmware but to no avail to camera performance (PDA and CSC parts only).

The poor picture quality you mentioned probably is due to out of focus, it should have nothing to do with the JPG encoding. Once I get the focus right, the picture quality is very good and I can assure you there is nothing wrong with the JPEG encoding. Try what I mentioned above - put the camera lens facing your object first before turning on the camera, I almost got the focus right every time now.

I have the same problem. Pictures taken with the camera are out of focus and of poor quality.

Will try the solution suggested.

Wondering, do you switch off/on the camera for each picture taken?

:P

Yes!! unless I know the next picture is of the same focal distance. Strange! but it works for me! how about yours? does that help?

[Guest eXPerience]

buff, it seems like there was a lot of autofocus problems, my omnia doesn't do any autofocus.

[Guest paramore]

my autofocus works great

[Guest rrr2]

Some minor improvement was noted using this method although not much.

Compared to other 5MP in Samsung Soul, it is still very bad.

Camera and GPS are bad on this highly priced machine :lol:

If samsung would not solve it by firmware means, it is big service time!

Maybe there is really hardware problem with yours. My autofocus works fine now with my method, and gps never gives me any problem.

Did you use XTRA for gps? you should, as othewise it'll take ages to position. With XTRA, it'll only take seconds.

[Guest thisrock]

Autofocus doesnt work in some first times. When switch on/off it works or switch record mod on/off. I don't know what the problem is. Also i8000 photo quality is not good. There isn't any solution to fix even all roms. :lol:

What exactly is the photo quality problem you are referring to? maybe I'm expecting not much from a phone camera, but my i8000 seems fine for the quality of a phone camera, among Windows Mobile phones I think it has the best camera already.

Attached is a photo I've taken off the foodcourt of a hotel in Macau, I think the details captured are fine :lol:

Do you believe your photo good is? I don't think so. Your photo has more grain. When I compare O2 and N95 photo deails i see O2 photos has more grain and brightness is very bad. O2 photos can fix only using software. You can look some photos i compared O2 and N95.

Omnia II photo

N95 Photo

Omnia II detail

N95 detail

I never said O2 has the best camera, I'm only saying among Windows Mobile, it has the best camera. N95 is not Windows Mobile, is it? I'm sure there are other newer phones with better camera. By the way, your second photo on the book is obviously a case of missed focus, which we were talking about all the while.

As to the grain (noise), you can't compare my photo with your other photos as the light condition is much dimmer in my photo. I'm sure even the N95 will display a lot more noise if photos are taken in dim light situation. As for the brightness, there is adjustment for brightness in the camera. My personal preference for digital photos however is always to underexpose a little bit (with my Nikon D90 as well), as one can always push up the brightness which sacrifice only in a bit of noise, but overexposed highlights can never be recovered.

You can refer to the i8000 photos in the following site, it is not that bad.....

You're right reay1234. i agree your all thinks. I'm only saying i8000 photos has more grain(noise) when i look its detail even in bright ambient.

I've looked the website photos you said, photos were fixed by ACD Systems software. Also phone versions are different. Maybe GT-i8000H model is better than mine.

Yes, unfortunately a bit of touchup is necessary at times, a lot of times the white balance will be off. I'm a photoshop man, so it's ok to me.... BTW, I don't think the i8000H is any different, it is just a version for Hong Kong/China, the hardware is same as any other i8000.
