    It's not _disposable_ it's _reusable_. The camera is returned to a
    Ritz Camera store where the pictures inside are downloaded to a CD
    or printed. The camera itself is kept by Ritz and recycled to another
    customer. In other words your $10.99 is a _rental_ of the camera
    with processing of the pictures included in the rental price.

    There's a picture of one of these cameras here.

    The USA Today article has some more details
    on the camera and its use including the fact that it is likely to be sold at Walgreens
    and Walt Disney theme parks (seems like a good idea to me).

    The camera has a 2-megapixel sensor.

      Yeah, but you can delete pictures, Stan! I was thinking the exact same thing- $10 for a 2 megapixel digital camera, even without an LCD that's a damn bargain!

      As I read it, you can delete the pix in the camera and re-shoot, but you can't view it.

      The viewing software is for the CD you get when you bring the camera back - at which point they dump the RAM onto the CD, give you the CD and prints, and keep the camera.

      My guess on what keeps you from keeping the camera forever:
      1) You can't get the pix out without cracking the camera software, which no doubt includes some serious access control as well as undocumented and perhaps non-standard interfaces, connectors, and protocols. (And they might hit you for DMCA violation by a number of routes, including claiming copyright to the pix themselves until you return the camera.)
      2) Eventually the batteris will run down if the camera is not returned for recharging.

      Still: I bet there will be a crack within a few months - after which it may go the way of the cue cat. (Depends on whether the loss rate from crackers keeping 'em is higher than their budgeted loss rate - which MIGHT not happen even if they ARE cracked.)

      The current 'disposable' film cameras have some reusable innards (I think), some breakable innards and a cardboard outer shell. From the pic at Technogadgets it looks like this camera has a molded plastic shell, but perhaps it is molded shut and has to be broken to get to the interface. That could be one control to discourage 'permanent renting'. Perhaps the breakable shell holds the lens in place or maybe if the shell is broken too much light will leak and ruin the picture quality of future pics.

      Or, maybe the I/O interface is proprietary and/or the processing lab has a device that contacts the chip package leads directly. Sure, a few web pages would go up describing how to read from it, but look at Xbox and Playstation. They're cracked, but it doesn't seem to be significantly impacting their business plans.

    The I/O connector is a PCB card edge with 10 wires. Kind of looks like the cassette port on a C64.

  28. How does it 'erase' pictures from film??? by BillX · · Score: 3, Insightful

    How is it that the camera can store its pictures on regular film (implying a purely optical process), but allow the user to erase a picture after it is taken? What exposes the film?

    (Unless the 'film' is really some kind of magnetic media, I'm stumped.)
