Nokia finally learned the trick in doing marketing.
MP counts, not sensor size. Lets see if its much easier to use than N8. |

QUOTE Purity of detail. Even digital SLR images have a certain softness. With oversampling, however, images can be noise free, yet incredibly detailed and defined. Zoom into the 5Mpix images at 100% magnification on your PC screen, and you’ll see. There’s something beautifully pure about the detail — not enhanced in anyway. Look closely at some grass… it’s amazing. Faster shutter speeds. With the Nokia 808 PureView, you get effective maximum aperture throughout the zoom range. Whereas with optical zoom, less light tends to reach the sensor as the zoom increases. At maximum zoom, 5.4x more light reaches the Nokia PureView Pro sensor than a broadly equivalent optical-zoom digital camera (f/5.6 as opposed to f/2.4). And this means you get the benefit of faster shutter speeds. e.g. If a conventional digital camera set to ISO 100 uses a shutter speed of 1/30th second, the Nokia 808 PureView uses 1/180th second in the same lighting conditions. Or, looking at it another way, if a digital camera uses ISO 600 for a shutter speed of 1/30th, the Nokia 808 PureView could maintain the same shutter speed with ISO 100 — significantly reducing the visual noise you’d see in the resulting image. This also means that the Nokia 808 PureView’s effective flash range is virtually maintained at all zoom levels, rather than being significantly reduced as the zoom increases. Goodbye to distortion. Distortion on all images is negligible. Whereas with optical zoom, images tend to get more distorted towards the edge of the frame (with bent vertical and horizontal lines) at the top of the zoom range. Silent zoom. The zoom function is completely silent — which is really important when shooting video. Less is more. The simple structure of Nokia PureView Pro beats more complicated designs hands down. Image definition is pin sharp, way superior to conventional zoom designs. Conventional designs need many more lens elements to provide the zoom capability and correct aberrations, but these interfere with definition and/or light transmission. Our simple structure has enabled a significant improvement in manufacturing precision, and our lenses are produced with 10x greater precision than SLR lenses. This was essential to allow the PureView Pro sensor and optics to work in complete synergy. They better deliver the goods as promised...

If all this Pureview is about post processing, it will be interesting to compare this with N8 if it get ripped off 808's firmware.

QUOTE(nicholasbeh @ Feb 28 2012, 02:53 PM) why still ARM11 is the point.why still symbian is acceptable coz upgrade still coming.from ARM11>ARM A8>ARM A9>ARM A15...now already A15 era... There is no point in using newer ARM with Symbian. Limited apps, no flash, nothing much, and some of the GUI already being accelerated by the GPU. Its just a dead OS. All they ever wanted from Nokia was a good camera, regardless of the OS or CPU/GPU. It will have a GPU, to help with HD and FHD video recording/decoding. |

QUOTE(sklchan @ Feb 28 2012, 03:04 PM) No... actually I want to find out if the camera is good or not to replace my half broken LX3. It has a slightly bigger sensor, more pixels. Just wonder if the camera software is capable or not. Im not interested in the efficient Symbian that runs very smooth on Belle with just 256MB RAM, and yet a simple game or app installation takes ages to complete. |

Anyway, I think there is a good reason why Nokia dont transplant this into WP7.5. All WP7.5 hardware is bound to Qualcomm chipset and I dont think Qualcomm can handle 41MP. Perhaps this will change in near future if Nokia really get special treatment from MS to implement its own hardware choice but wait n see for the moment being.

Basically what Nokia did is take a 41MP and then resize it to 8MP resolution for 5times the pixels. Still its pretty interesting to see the result that normally people would say not good when using too many MP with a smaller sized sensor.

QUOTE(Andrew Lim @ Feb 28 2012, 02:27 PM) The stock Android launcher and browser scrolling is seriously flawed. I'm 99% certain that it's the animation algorithm Google's using, so it doesn't matter if it's dual-core, quad-core it'll always lag because it's not redrawing consistently and maintaining a stable frame rate. I think you must be using dinosaur aged Android. It has been for some time that Samsung and even Motorola reverse engineer Honeycomb browser over to 2.3.x which result in GPU acceleration for browser. Even ios also stop showing chequered boxes after v5.Google needs to hire a video game programmer to show them how to maintain a stable update-per-second and frame-per-second even if the processor is some cheapo single core, because desktop games have been doing this without problems since 1995. |

QUOTE(Andrew Lim @ Feb 29 2012, 02:51 AM) I did say stock Android. I tested Galaxy Nexus Ice Cream Sandwich. Lags a lot compared to iOS and WP, especially with Live Wallpapers. It may be GPU accelerated but they're still using a crappy rendering feedback algorithm. Android 2.x is not GPU accelerated but let's not go into that.Even on the SGS2 with I think has a better GPU the home screen swiping doesnt feel as responsive as iOS. This is not a GPU/CPU issue, it's a rendering algorithm issue. |

QUOTE(stimix @ Feb 29 2012, 07:31 PM) If the sensor as big as APS-C like NEX, or even Alpha SLT/ Nikkon/Canon DSLR, than only can compare.. now still kenot..Still smaller than micro 4/3 as this is only micro 4/5 size haha The NEX is quite a capable camera to compare with. If it beat LX3/5 or similarly sized prosumer camera, then it's good enough to replace a camera. The hardware is there but only left the software. Well, well... Pray hard |

That sensor size comparison chart is not correct issit? I can't see it as being 2.5x bigger till I see this pic.

QUOTE(haley0918 @ Mar 2 2012, 05:07 PM) on software point of view, you can't just level a group to the best in the group And its a very powerful chip judging from the video of photo snapping. To examine each and every pixel of the 41MP and amending the pixels yet only takes a second or so.for this to happen, you'll need to implement artificial intelligence to somehow conclude the best one from the group and the difficulty is on how you going to know which is the best in that group the sensors are exposed to random colours at specific time further more if artificial intelligence was implemented, it will require more processing power than this 1.3GHz and it has already been explain that a proprietary chip has been developed for this tech |
