Megapixels & Camera Phones

CEmongler writes "Consumer Electronics publication CoolTechZone.com tackles the integrated camera attachments in today's cell phones. According to the author, "The camera integration has in fact reached such a stage that any self-respecting phone would incorporate at least a megapixel camera. The cutting-edge feature to have though is the 2-megapixel variety. The question is: is it really worth the extra money you pay for it? Without getting into model-by-model comparisons, I am questioning the entire range of 2-megapixel camera phones. Are they really worth it? For the most part, no."

    Look, the number of pixels is simply not as important as the optical properties of the system. I've seen better pictures come out of a four megapixel (MP) camera with better lenses than those that come out of a seven MP camera with poorer quality optics. So, if your lenses allow clean transmission of light without chromatic aberration and little to no change to the fidelity of the image, then you will have better images than just simply bumping up the MP count through commodity CCDs.

    This of course is what the phone manufacturers are doing, buying commodity CCDs because that is what is being made. It is cheaper for them to spend an extra dollar or two on a higher MP count CCD rather than putting the development dollars on improving the user experience, interface or infrastructure.

    This of course is because people respond to higher MP counts in the same way they like "bling". "Ooooh shiny things!" Come-on people! Put some effort into purchasing quality products that demand a bit more work and are functional for longer periods of time instead of purchasing things that you throw away after only a short time. It shows you are more discriminating, pushes companies to produce better products, is easier on the environment and gives you better quality goods that help to improve your life rather than clutter it up with junk.

      Yes, it's partly the optics. Mainly it is the size of the imaging sensor, though - or to be more precise, the size of the individual sensor sites. Smaller sensor and higher resolution both mean smaller sites, and smaller sites mean more noise.

      In the end, you will not be able to ever get the same quality out from a tiny unit like on a camera phone as you get from an APS-sized fixed-lens or SLR-type one.

      That said, I have both a DSLR and a 1.2Mp cameraphone and they both have their uses. The DSLR is more important of course, but I would not want to be without the cameraphone either. Even though I drag the big camera around most of the time, I still now and then find myself in situations where I didn't have it, or taking it out would have taken too long and drawn too much attention, or I just wanted to send a picture of something to my SO, and going via DSLR, computer and email was at least two steps too many and half a day too slow.

    I did not own a digital camera up until this xmas, and it was a gift. I purchased my w800i because it's sort of a MacGyver-esk tool used for pictures, music, and communication.

    Since I prefer film vs digital, I thought it would be nice to consolidate tools into one device that I have on me all the time. It has proved to be a good investment, despite the $400 investment. The premium price I paid has a lot to do with markets and such, but those aside, the phone fits its niche in my life and it's always convenient to have a camera on you at all times.

    Most phones available in the US have really crappy cameras, but the w800i is an exception.

  4. No, they're not worth it! by vidarlo · · Score: 3, Informative

    And why? Because the optics still sucks. I guess there ain't enough space for a good camera inside a phone, because the optics ain't small enough. While the ccd or cmos sensor is small enough, it needs good optics to give good quality.

    Say you've got the good optics, and a decent sensor... A ccd uses more power than a cmos, and needs more light. A cmos however, gives lots of artifacts (noise) in the picture, but performs better in low-ligt conditions, and needs less power.

    • CMOS sensor - low power, low light level needed, but artifacts (noise) in the picture
    • CCD sensor - powerhungry, needs good lgiht, good quality

    Ok, so we go for a ccd. Then we need a good flash, which takes even more power. Power which has to come from a capacitor since a battery can't deliver high enough voltage and enough current fast enough. A capacitor and flash takes up space.

    In short, if we want small phones, we won't get decent image quality. If we can accept a phone twice as big as the ones we have, we can just bundle together a normal compact camera and a phone...

    The whole "cameras in cell phones" craze is starting to cause some problems for me. Many DoD installations do not let you take camera phones onsite. This has the effect of severely limiting my cell phone choices, so that I'm stuck with "crackberry" or "super cheap", neither of which is terribly appealing. What happened to a nice, mid-range phone with no camera? It's not even that I don't like a camera integrated into it - it's just not an option for me. This insanity is even starting to creep into PDA phones - witness the Treo 650's digital camera, for instance.

    It's gotten to the point where I'm thinking of switching from Sprint to Nextel, just because Nextel's phones actually seem more reasonable for my (and my wife's) usage. Interestingly, the Sprint rep I spoke with said I could do this, and they even had a group for going from Sprint -> Nextel!

    Having a 2 megapixel camera is pretty pointless if you only use it to put a picture of your partner on the phone's main screen, or to send multimedia messages (which reduces the quality to something like VGA quality).

    However if you can get the image from the phone to an internet site like Flickr, TextAmerica, Kodak, &c, then it is worth having a 2 megapixel image, just like it's worth having a decent amount of megapixels for your regular digital camera. The higher quality is useful for displaying on a PC, or for printing the photo, and so on.

    Unfortunately it's very hard to get your pictures from your phone to the internet. Email and WAP uploaders have proved not good enough for this task, and hardly anyone does this.

    A new generation of software is emerging on phones though. Services like ShoZu allow you to upload full quality images from your phone to sites like Flickr, TextAmerica, &c, in a very simple manner, and also allow editing of titles, descriptions and even tags both before and after upload. With this sort of service on your phone it really is worth having a decent camera in your phone.

    We used to use a regular digital camera, and just keep one in each conference room. But they kept growing legs, getting misplaced, needing batteries, or just malfunctioning. Cameras that are owned by individuals have the advantage that the individual actually takes care of the thing, so it is much more likely to be available and work when it is needed.

    The key to any tool is to use it appropriately. A camera can be misused, such as to transmit confidential material to a competitor. A camera can also be very useful, to record and communicate drawings within the company.

    Banning cameras does not protect the confidential information, unless the organization also bans email, removable disks, printers, paper, and briefcases.

    The phone is a Nokia N70 and, for all of its foibles (including the incredibly annoying slide open camera activation / lens protection cover) the camera stands out as a superb product.

Yes, in low light it makes everything look incredibly washed out - yes the delay is enormous on taking a picture - but in good average daylight conditions pictures come back looking almost as good as those of my old 2MP Olympus point and shoot which i've since retired.

    One of the 'points' of camera phones for me was just having a camera with you at all times in case something unusual happened - be that a car accident (and you need to record photographic evidence of the scene), a good sunset, etc - the increase in MP allows you to do this more and more - previous generations meant that the picture was only 640x480 or so and this didn't really allow you to get the whole picture across!
