Nokia Puts 41MPixel Camera In a (Symbian) Phone

judgecorp writes "We aren't sure what's the strangest thing about Nokia's new offering, the fact that it's got a 41 Megapixel camera or the fact that it runs Symbian. It has a very high resolution sensor and uses oversampling, apparently producing good results in low light. Users can either save a maximum of 38Mpixels, or else zoom and crop for normal resolution images. Observers expected a maximum of one more Symbian phone before Nokia shifts over to Windows Phone. This suggests either a longer life for Symbian — or maybe [that] Symbian was just an easier platform to make a show-stopping device that may turn out to be more of a concept phone."

      A typical consumer CAN compare two numbers and figure out which one is larger. Since this something everyone can do, that is where camera marketing has focused.

      Canon, for instance, pushes sensors with huge megapickle numbers, but side by side their resolution is the same as the competing level Nikon or Sony. The only way you're going to get an actual resolution increase over the ASP-C sensor is going larger. All other factors being equal, a full frame sensor (35mm) produces a better image than an ASP-C. A medium format sensor (60mm) produces a better image than full frame (35mm), and so on.

      So why is Nokia peddling on the megapickles instead of the oversampling or the digital zoom abilities, or the sensor size?

Larger sensor collects more light. More light on the sensor means less sensitivity gain, means less noise in the picture it produces (particularly in low-light). Even if you compare two identically sized CCDs, one with eight times the pixels, you end up with eight pixels with significantly more noise than your single pixel simply because less than 1/8th the light is hitting each of those sensors (hence an even *higher* gain on each of those).

      I'm not saying it's going to be a bad cell phone camera, I'm simply saying that increasing the number of pixels over the same surface area of the sensor doesn't in and of itself give you a better image.

I have a $125 lens (the Zuiko Digital 35mm f/3.5 macro) which easily satisfies this criterion: it delivers images that contain detail all the way down to the pixel level on a 12MP sensor (i.e. 3000 lp/ph) with a 2x teleconverter. (I use this in the field to get more working distance for bug shots since 35mm is quite short for a macro lens.) Thus, it will deliver useful detail to twice that resolution without the teleconverter, which corresponds to a 48MP sensor at the 4:3 aspect ratio.

      This is a $125 lens. (It's also the sharpest I own.) If a cheap lens can do this -- and can do it when focused well into the macro range, which provides special optical challenges -- then there are plenty of more expensive ones that can, too.

      Another test is to look at an extremely dense sensor already in existence: the 24MP Sony NEX-7 sensor, which has a crop factor of 1.5x. It's got the same pixel density as a 50+MP fullframe sensor. But people use fullframe lenses on it, such as the Carl Zeiss ones built for the Sony mount, or Leica M lenses, or whatever, and get useful detail out of all that resolution. Those lenses, then, are capable of delivering useful detail to a 50+MP fullframe sensor.

      Zoom lenses may have trouble resolving this sort of detail, but even most cheap prime lenses can. (Of course, the very fast ones won't be able to at f/1.4...)

      Actually, Nokia has never been known to be very consumer oriented. And about not cutting deals with carriers => That's why my second last Nokia (the last one has been the N900, completely different story), the E61 has had a couple of dozen different firmware versions, customized to the likings of the specific carriers. And it strictly (without TLC) refused to cross-update the phone.

      One of the popular "bad things" was to bind a key to the "WAP" internet browser, and disallow reassignment => every time somebody without a data plan (back than that was most) pressed the button by mistake, the carriers cashed in nicely.

      Currently, Nokia has NO phones worthy consideration, but they still have a number of rather nice Bluetooth accessories :)

      And yes, the company completely lacks leadership and vision. OTOH, Nokia going down will be painful for the industry, because of the hugely expanded "Intellectual Property" rights as pushed by the US administration and multinationals. Nokia has been a big player in the mobile industry for way to long not to have amassed a huge pile of IP. And while they certainly have a number of FRAND patents, I don't think that's the whole story: FRAND is required for critical must have patents for industry standards like GSM/UMTS. The interesting stuff is not there, it's all the stuff around the core. Patents that are not critical, but not having them makes it awkward to do mobiles. (Analogy: Every one can get a patent at FRAND conditions to produce a knife, but the patents on putting a handle on the knife are not FRAND as you can cut stuff with a blade-only knife. Much fun with your blade-only knife.)

If you want to retire a platform, retire it with the new and *better* replacement already in stores.

      I think people are focusing on the overkill of 38 megapixel image on a camera phone. Sure, it's kind of cool from a technological perspective, but from a practical standpoint, considering the limitations of aperture, focal length, optic distortion, etc., constrained within the tiny framework of a phone is pretty pointless - even Zeiss optics have their limitations. Also, as mentioned previously, one can only allow so much light into a small and tiny lens (which is limited by the form factor of the size of the phone.)

      The concept of taking a oversampled image to produce a superior lower mega pixel image is not new. It's called a loss-less digital zoom (which does sound like an oxy-moron) but as you mentioned was part of the story's approach. My old Sony DSC-V1 (2004) with a 5mp sensor has a similar feature - set your saved picture size down to below 5mp and you would get an extra bonus of loss-less digital zoom due to the oversampling. Interestingly enough, that camera would not permit you to digitally zoom beyond anything that would sacrifice quality.

    Actually since this is a near diffraction limited lens working at f/2.4 the spot size is going to be about 0.56um * 2.4 ~ 1.344um on the focal plane. The cycle size is about double, or 2.688um.

    Considering it uses a Bayer array, and the pixels are spaced at 1.4um, the green pixels will be spaced at 2um (minimum distance to next green pixel). To properly sample you need at least 2 pixels per cycle (said Mr. Nyquist), but since pixels are not exactly points (they have an area) astronomers working in diffraction limited imaging advise 3x sampling in practice.

    What this means is you would need a pixel size of 2.688/3/sqrt(2) ~ 0.63um (or 0.9um if using a Foven-style sensor) to properly sample this lens. 1.4um vastly undersamples the lens, as can be seen near the central area in the available samples: they are razor sharp in the central area, and otherwise are limited by aberrations.

Who cares about frame rate? Well, it's the reciprocal of shutter speed. So, you're looking at long-ass shutter speeds, and you will never be able to capture spontaneous shots.

      You read that wrong, apparently. The lens is more than good enough for the sensor. Your point about shutter speeds is wrong, too. The light falling in any given area is the same as it would be for any other f/2.4 lens, and the sensor has a mechanical shutter, too, so readout times are not determining shutter speed. The problem is not a lack of sensitivity, either, as the pixels are the same size as regular cameraphones and the effective pixel size can be increased (and noise can be reduced) by using a 5-8Mpix downsized version. There is a slight penalty to be paid in higher readout noise relative to signal (lower light per pixel, same readout noise as a big pixel), but is a relatively small price. In fact there is also a neutral density filter that can be switched in front of the sensor to reduce the light and allow longer shutter speeds in bright light (allows blurring moving objects a little.)

    OK now lets talk about a 43mp will look after this process. Or for that matter even a 5mp super-processed perfect picture.

    1. Keeping the phone in a pocket or purse.
    The lens will invariably get covered in dust, fingerprints, and get scratched from cleaning with a t-shirt. This will take about 24 hours from the purchase of a phone to degrade the lens to a point where even a good 43mp imaging system will look like a carnival mirror.

    Hand-holding a camera invariably add some jitter to the image. You will have better luck in daylight but indoors or at night, its enough to degrade the image from slightly soft to psychedelic . Oh dont you wish the phone had a flash? Most dont because it drains the battery and adds bulk.

    The "41 megapixel" helps in impressing people but the really interesting thing in this phone is the size of the sensor (see dpreview for a comparison of sensor sizes). Physically larger than the majority of sensors found in compact cameras, it allows for better image quality.

    It is likely that a 5 megapixel sensor of the same size would be equally and even better suited for taking images in low light conditions but such a sensor would lack the so-called "digital" zoom described for the PureView phone. The "zoom" is nothing more than cropping the image to smaller and smaller sizes and lower and lower quality. But it is there.

    I do hope that compact camera makers will follow the example shown by Nokia and provide the new models with larger sensors providing better image quality. It is likely that such a move is detrimental to camera makers as it might steal from the dSLR territory.
