Comparing dual LED to Xenon Flash - N82, N86 8MP, and N79 Low Light Showdown!

The Nokia N86 8MP (right) is positioned as Nokia's premiere imaging range of camera phones for 2009 and set to replace the venerable N82 (left). It is Nokia's first device to feature a wide-angle 8MP Carl Zeiss len camera with variable aperature and second generation dual-LED. Unfortunately, many N82 users bemoaned the absence of Xenon flash. Nokia responded with a slide show comparing the N86 8MP to N82 in low light which mainly focussed on when flash would be triggered when taking the photo of close stationary objects. Interestingly, they didn't address flash distance or moving objects in low light. Which I think are more important in real life situations such as taking photos of your friends at a bar or your children going trick or treating during Halloween.

Full review after the jump.

Flash Distance

All camera phones were set to auto mode with automatic flash in a room with no light. I placed 3 objects on the ground a meter apart from each other in front of the camera. The big boxes were 4 meters away and the wall was about 5 meters away.

N82	N86
ISO-800	ISO-460

N79	E71
ISO-1664

ISO-200

The N79 had to increase its ISO setting very high to brighten up the image which led to a lot of noise and a generally useless photo. The E71 was totally useless. Obviously the dedicated camera produced the brightest flash and clearest photo.

The N86 is a significant improvement over the N79 even though both use a dual-LED flash. I'm sure the larger sensor and improved LEDs helped the N86.

The N82 produced a much noiser photo compared to the N86 and the N82 needed a higher ISO setting to get a similar brightness to the N86. So just to see what would happen if I set the N82 to medium ISO to force it to use ISO-400.

With similar ISO settings, the N82 produces a definitely darker image, similar noise, and very similar details.

WINNER: N86 8GB

Photo capture of a moving object with flash

I used a metronome since it has a generally consistent speed, easily recognized by readers all around the world, and has various speed settings. I threw out all photos of the metromone arm at the very far right and very far left since the arm moves much slower at that point. I took 3 photos with each phone at each speed setting.

I found that each phone produced consistent image quality between the 3 photos taken. All camera phones captured photos between 100-200 ISO regardless of metronome speed. Now let's look at the detailed results.

Low speed (40 GRAVE)

Mid speed (72 ANDANTE)

 
High speed (120 ANIMATO)

The N79 and N86 produced similarly blurry photos of the metronome arm. Although the N86 sensor can take clearer photos of stationary objects, the sensor still can't get enough light in a short time to capture a still photo of the moving object.

It's no question that Xenon pays dividends with a clear photo of the metronome arm. As reported in many studies, Xenon produces more light at a specific object in a shorter amount of time than LED can. Which is why photos tend to be blurry in dimly lit environments when taken with current camera phones. Let's hope that either LED technology makes some significant improvements soon or Nokia switches back to Xenon for their next premiere imaging device.

WINNER: N82

Conclusion

Overall, the N86 surprised me by it's impressive flash distance that produced images of very little noise, even when compared to the N82's Xenon flash. But as predicted the N82 captured motion photos significantly better than the dual-LED equipped N86. Comparing the N86 to the N79, we saw an impressive improvement to the dual-LED and sensor technology that allowed the N86 to produce far superior distance photos. So it's a give and take with the N82 better at freezing motion while the N86 is better for distant stationary objects. I personally would prefer freezing motion for clearer photos while the flash distance is comparable. Until Nokia releases another Nseries with Xenon, the N86 is definitely a worthy device that gives the N82 quite a run.

Vampent vBagX Review: Gameboy Advance on your S60

http://www.vampent.com

While Nokia is trying to build creditibility to their N-gage mobile gaming platform, much of the portable gaming market was and continues to be held by dedicated gaming systems like Nintendo's DS and Sony's PSP. Just the number of top rate games available on one of these systems far outweigh all the games available on the S60. One way to quickly increase the number of top quality titles is bringing it onto the S60 through emulation.

The power of S60 phones have dramatically increased in the past few months and software like vBag make emulation of yesterday's dedicated portable gaming systems like the hugely popular Nintendo Gameboy Advance possible. With vBag your phone can play any number of games from the GBA's huge library of portable games. Imagine classic like Super Mario Advance 2, Super Mario Kart, and the Legend of Zelda on your phone:


It may sound impressive so find out if the claims are true that you can really get the GBA experience on your S60 phone by following the jump to read the full review...

For this post I will be reviewing vBagX x1.20 S60v3 on the most common Nokia S60 architectures:

Architecture	Details	Phones
32bit Freescale MXC300	369 MHz ARM1136JF-S + 220MHz StarCore SC140 DSP	E63, E66, E71, N78, N79, N81, N85
Texas Instruments OMAP2420	330 MHz ARM1136 + 220 MHz TI TMS320C55xDSP + PowerVR MBX 2D/3D Graphics Accelerator + IVA	N82, N95

I don't have all of these phones so I'll be testing on both a N82 and a E71 to cover both of these architectures on vBag 's performance. A SanDisk 8GB microSDHC class 4 on the N82 and a Nokia 2GB microSD on the E71 memory card were used during this review. vBag was installed on the memory card in both cases because all GBA ROMS (.gba) must be placed in \Data\Others\vBag\

Graphics
vBagX gives you the option to use Bitmap (software rendered) or Direct (hardware rendered) but Direct has never worked for me on either the N82, E71, or even other Vampent products on my 6682.

From my experiences, the E71 renders games exactly as they are on the GBA but some games do run into issues with sprites not appearing in the right spot (see compatibility).

Super Mario Kart Advance runs smoothly with all image layers on the Nokia N82

vBagX comfortably handles the portrait layout found on most S60 phones like the N82 and the landscape layout like the E71. It can also handle screen rotations but the rotation must be done before starting a game otherwise the rotation will cause a screen problem. You can also manually change the screen orientation under Graph > Size (you can rotate the screen 90 degrees left or right, keep it at original reolution or expand to fill the screen).

You do encounter some frame drops here and there even on the higher powered N82/N95. The E71 is more choppy. You can adjust how much frames (0-9) you're OK with vBagX skipping to keep a consistent game speed.

Sounds
vBagX supports full stereo audio on the GBA. However there is a very very minor lag in audio on the N82 but the audio was very out of sync on the E71 by about 0.5 seconds.

Performance
This is highly dependent on the model and firmware of your phone.

My E71 encountered choppy frame rate and lagged audio. There was no way I could play Street Fighter II the same way as I did on a GBA.

I didn't experience any of the lag with the dual core architecture of the N82. But there were a few dropped frames here and there in high speed games like Super Mario Kart. It was very playable but not as smooth as playing on a real Gameboy Advance.

Compatibility
There is currently a running thread of compatible games on Vampent's forum. Here is a list of games I've tested and played:
Super Mario Kart
Super Mario Advance 4 (Super Mario 3)
Super Mario Advance 2 (Super Mario World)
Contra Advance (Contra 3)
The Legend of Zelda - The Minish Cup
Final Fantasy Advance Tactics
Mario Pinball Land
Super Street Fighter II

All of them worked for me running on compatibilty mode 1. That's the scary but powerful thing. Vampent thought to add a compatibilty setting that goes from 1 to 3 (where 3 is slowest but closest compatibility with GBA) in vBagX so some games work in one setting but not others.

The single core architecture used in the Nokia E71 lends itself better to RPG games like Final Fantasy Tactics Advance

Phone keypads for gaming
You're playing games designed for the GBA's keypad. First off you're losing out on the left (L) and right (R) buttons at the top of the GBA since no S60 phone features these. Secondly, the ring D-pad of most S60 phones don't lend themselves well to diagonal (ie. left-right) presses. Similar to the keyboard on computers, a certain combination of simulataneous key presses can register an error on the phone and thus ignoring the key press. It's annoying when you have to hold one key while tapping another like flying in Super Mario Advance 4.

If you can get past all those physical limitations, vBagX allows you to map any GBA key to almost any phone key. Unfortunately only the volume up/down media keys are currently supported for N95/N96.

I've frequently referred to vBag, vNes, or vBoy under the keypad sections in my reviews as these games were designed for the highly comfortable, high quality, and dedicated to gaming keypad of the Nintendo Gameboy Advance. More often than not, the keypads of a phone aren't built with gaming in mind so button placement is compromised and button quality isn't high on the priority of phone manufacturers. If you plan to game a lot on the road then I highly recommend bringing along a Wii-mote and downloading Mobipad so you can use the better Wii-mote controller for gaming.

Playing GBA games with a Wii-mote paired to your S60 phone via Bluetooth is a lot more enjoyable and comfortable

Overall
vBagX delivers high quality gaming to the S60 platform by giving users access to Gameboy Advance's library of games. Most of my Gameboy Advance games ran fine on vBag with an acceptable framerate, little to no graphical errors, and mostly synchronized audio playback. Since most games require quick reflexes and timing, you need to get either a N82 or any flavor of the N95 to fully enjoy vBagX. I highly recommend downloading the trial vBagX to your phone to test before purchasing it to ensure it runs your favorite games smoothly and you're confortable with the keypad on your phone. If you do decide to purchase vBagX, Vampent offers lifetime upgrades of the vBagX product and I've heard their customer service is really good.

Software rating: Highly Recommend

Nokia N95, N82 Turn Off Camera Sound

Since there are a number of people out on the web searching for turning off camera sound or shutter sound, I thought I'd post an entry on how to do it.

First try changing your phone to silent mode. Try taking a photo with the camera. If that didn't work then your phone's regional firmware probably doesn't allow silencing or disabling the camera sound so you'll need to read below.

Note: I do not endorse this but if this makes you happier with your Nokia S60 then it's worth it.

Warning: This involves updating your phone firmware so it's a risky procedure. Updating your phone is at your own risk.

Pre-requisite:
- Installed Nokia Suite Software that came with your phone
- Installed European Nokia Software Updater
- Phone
- Nokia USB Cable

First Part: Changing the product code on your S60 phone

Warning: This first part voids your Nokia warranty

Update 10/06/2008: 1.0.38.14 fixes a bug that prevented NSS from comunicating with the new Nokia Connectivity Cable driver
Download Nemesis Service Suite Beta 1.0.38.12 1.0.38.14 from B-pheaks (NSS103812.exe, 6,629,190 bytes) (NSS103814.exe, 6,514,081 bytes)

Note: Updating Nokia Software Updater will override your USB drivers and prevent NSS from properly reading your Nokia phone. I would suggest using the European Nokia Software Updater 1.4.23. - fixed in NSS 1.0.38.14

1. Install NSS and restart computer


2. Connect your phone to the computer via USB cable and set to PC Suite mode.


3. Open nss software click on magnifying glass in top right.
   
   
   
   


4. Click phone info and scan your phone just to make sure its connected
   


5. To the right, click read to bring up your product data.
   


6. Write down your product code.


7. Change the product code one for EURO 1, 2, or 3 (see here for a listing of product codes for your S60 phone, I use EURO 3 - N82 RM-313 = 0551521) and check enable box then click on write.


8. You must reset the phone in NSS software. Click on tools tab then factory settings tab.
   
   


9. Check the full factory circle and click reset.


10. Restart your phone (I don't think this step is necessary but let's do it just in case)

Second Part: Update Phone Firmware

1. Update your phone as you normally do and remember never to turn off your computer or phone. And remember it's normal for the phone to blink a couple times. Don't do anything to it and don't run anything on your computer at the same time.

That's it! Try out your camera now.

I would suggest changing your phone's product code back to the original value using the first part of this, just in case.
