Samsung Producing 5 Megapixel Camera Phone 177

Posted by michael from the convergence dept.
Shippy writes "Straight from Yahoo News on the other side of the pond comes a story about Samsung's latest creation: a five-megapixel camera phone. This is pretty cool considering it's a pretty big jump from the camera phones that are currently available (many max out around 1.5 megapixels). It's expected to be available by the end of the year, but only in South Korea. I doubt it'll take long for a domestic carrier to pick up on this hot new toy."

    Until phone manufacturers make phones with a good quality Xenon strobe flash, 5 MP still doesn't mean anything if the lighting conditions stink. (See this month's issue of PC World for a little blurb on possible developments of Xenon strobe flashes in camera phones.)

      • The press release says that the phone is, in part, the result of a collaboration with Pentax, who have some considerable experience in making camera lenses.
        • While Pentax make better lenses than Kodak, when I studied photography at college (quite a while ago) we did resolution tests between various 35mm SLR cameras. While Pentax and Nikon did quite respectably, an Olympus with a Zeiss-Ikon lens was streets ahead, with comparable quality to 2 1/4 inch cameras.
        • Many people seem to think that MP is directly proportional to image quality. Not so. The MP is part of the equation, but mostly tells you how big your pictures can be (print sizewise). The real quality lies in the image processing capability, the size of the CCD, and the kind of lens that the camera uses.

    The definition of megapixel is slippery. Sometimes these companies allow for interpolation for some reason (they are liars!). Some camera, such as the Foveon, only have 3.1 megapixels but behave like a much higher megapixel camera. This one I can't tell about what is the reality.
    • The story with the Foveon is that it has a fundamentally different way of forming a color image. Current cameras use what is called a Bayer pattern, where the pixels more or less alternate between being red greed and blue, and interpolation is used to get the full RGB value at each pixel. The Foveon camera actually has 3 separate chips for the RGB. So actually most cameras that say 6.1 m color are 6.1 m b/w in some sense.

    I recently got myself a Motorola v220. Got a cute little 640x480 camera on it. Only problem is the only way to get the photos from the phone to my computer [or any other storage] is to either buy the 70$ software from motorola [that should have come with the phone] and run windows [something else I don't do] or pay 5 cents per kilobyte to email myself the picture.

      I'm studying in Japan this semester, and I've seen tons of phones here far more advanced than those in America. To address your concern, though I don't know about the Samsung camera in particular, alot of the phones here with 1-2 megapixel cameras have flash RAM sockets for storing/retrieving pictures. I would imagine such would be the case for this new camera as well.

      And in response to the "it should be imported any time now" comment, I would have to say that's highly unlikely. The phones here that have features we in America wouldn't even dream of. Everyone here has 1-2 mpixel cameras, and some phones even have videophone capabilities; Hell, this one [sharp.co.jp] even has a TV/FM tuner built in! I actually held it in my hand, and watched TV on a cell phone. In-freaking-credible. But seeing those kinda phones all over the place here, and nowhere in America, I'd have to say the creation-to-import lag is quite high.

The blame almost surely rests on the shoulders of the carriers, with about 25% of that being the consumers fault.

The same argument applies to the rest of the market.

    We, the consumers are locked into a rut where we don't quite have the money to start pushing the 6 month product cycle. Until we start upgrading our phone everytime a new model comes out, the carriers are still going to maintain high prices with slow product upgrades. Right now the mentality is that the average cell user signs a year contract and then never upgrades the phone during that year. With no drive to upgrade, there is no drive to innovate. With no innovation, there is no competition. With no competition, prices will stay rediculously high. And we, the consumer, will keep paying $300 for 2 year old technology.

    A high pixel count is great, but if you want a good picture, you need good optics.

      ...which need a lot more space than those tiny lenses built into mobile phones. That's just one of the reasons mobiles can't replace real cameras.

      I'd rather carry a small mobile and a decent camera with me than a device which makes bad pictures and is a pita to call someone.

        Aren't fluid lenses [dpreview.com] on the verge of revolutionizing the size (or lack thereof) of digital camera's?

        Even if they aren't, I would never use the expression "can't" when it comes to technology, and especially not when it comes to the size of lens systems. After all, nature has demonstrated that lens systems can be versatile, high-quality, and positively tiny. If nature can do it, eventually we'll do it too.

          Although they certainly sound interesting (and useful), I don't think that they address one of the primary problem with small lenses: a small lens can't gather as much light as a large one. That's a physical limitation, and one that we can't just get around.

    I bet Verizon picks this up.

    Of course, they'll reduce the camera to 2.0 megpixels, cripple the OS, and in addition to the half dozen Verizon logos on emblazoned on the phone, they'll make sure there's at least another half dozen built in to the phone, usually doing something incredibly obnoxious, like alternating displays with the clock...

    The rush to higher density CCD's is insane.. but it's an easy number people seem to be able to understand. The optical lenses used are often much more important once you go beyond a certain threshold, e.g. 3-4MP. What's next, a 8MP camera phone? Why?

    Camera phones have a limited ability to hold focusing and zoom lenses, and the sooner people understand this the better.

    The end of the article says this:
    "South Korea's top mobile carrier, SK Telecom, said it would introduce 10-megapixel camera phones produced by Samsung by the end of this year." If this isn't a mistake then this is quite a staggering rate of change in camera phones.

  • Not being an optics expert, I still have to wonder whether the quality of pictures from a 5 mp camera will be wasted with the typically small and cheap-looking lenses on these phones.

    Is this going to be an issue on these devices, or have manufacturers been able to mass produce high quality optics so that even 16 megapixel cell phones will be affordable and useful?

  • Cool, another camera I can't own because I can't take it to work for security reasons. Thanks Samsung!

    Tell me - if you put a black panel against white wall and snap it in the focus - how many _pixels_ would the border be? 10? 20? 100?
    BTW - the simple rule is that you need only 1 MP per 10 sq.in. of print for _critically_ sharp images, i.e. those that best of modern printing equipment can realistically produce. For printing in your photolab (moreso inkjet) you can divide that by 4 safely. The question is that all those MPs from the camera are somewhat fake, see above.
    PS: What's the matrix size of that phone, anyway?

    Adding a 5mp camera to a telephone has been done mainly for marketing reasons. People who don't know anything will see the bigger number and think that it's better. The problem is, you need VERY decent optics to take advantage of a sensor with a 5 megapixel resolution. The TINY lenses that you will *always* get in a camera phone (unless you want your phone to be the size of a brick) will never be able to do justice to a 5mp CCD. Apart from anything else, a lens that's only a few millimeters across cannot gather enough light to let the camera expose the picture for a short enough time for it to still be sharp at that resolution. What I'm trying to say is, your pictures will have camera shake nearly all the time - even when a normal camera with a decent lens wouldn't have even used it's flash.

    Basically - don't bother spending money to get a phone with 5mp instead of 1mp. 1mp is fine for instant snaps to put on your blog, but you're never going to want to print out your holiday-of-a-lifetime photos taken on a telephone with a 5mp camera coupled with a 3mm plastic (or glass if you're lucky) lens. Especially if said lens has been in your sweaty pocket for a few months and smashed against the tarmac a few times!

    If you want decent photos, get a decent camera with a decent zoom lens.

    Don't try and take photos you want to print out with your telephone! That's NOT what telephones are for - contrary to popular media hype.

  • Given the prevalence of camera phones in Japan, does anyone there try to ban their use in places like washrooms, change rooms, movie theatres, etc? Is it even possible to get a "pure" cellphone (no camera or fancy extras) in Japan these days?

    If I had a 5-megapixel camera-phone, there'd be two things I'd worry about: 1. Vibration- It always seems I can't keep my hands still when I photograph, and I can't imagine using a monopod or even a tripid with a cellphone. 2. Flash- It always takes a lot of battery, so I can't imagine the life would be very long. 3. Zoom- You're not going to have a very good zoom on something fitting in your pocket. Of course, with a camera phone you're not trying to take good pictures, just those spur of the moment ones before I get the good one out.

  • Even if it is 10 MP. If you have 5 MP and a crap lens with small aperture, little or no zoom, made of plastic, one or 2 elements, your pictures will still be crap.

    A phone does not lend itself to a good 3X lens because of the bulkiness, complexity and cost of such a setup.

    The only good news here is that the price of 5 MP CCDs is dropping to the extent that they made their way to phones.

    Ya know, with 5mp, suddenly a decent-looking digital zoom (when the output stays 640x480) becomes possible. You can't zoom optically in something this small, but you sure can digizoom it. Even with cheesy optics, that's got to be a selling point.

    After all, it'll be a while before we regularly trade 2Mb photos with our pals on their cellphones with 120x240 screens.
  • Five megapixels? Who are they kidding?

    Other Slashdotters have rightly pointed out that this is approaching the absurd, given that the camera has a) a weak flash; and b) very little glass (small and likely low quality lenses).

    It should also be noted that the CCD is probably pretty tiny, too.

    Question: What do you get when you combine low-to-moderate ambient light levels with a poor flash, a fairly small aperture lens, and a tiny, overdriven CCD with miniscule pixels?

    Answer: Crappy images. I shudder
