    I notice that Panasonic is coming out with a video camera, the PV-GS400,
    that is capable of taking 4 megapixel stills. Normally the still capability
    of video cameras is pretty poor due to the tiny ccd sizes, but the area of
    this sensor is pretty large. I think it must be close to a 5/8 ccd in total
    area. Does anybody think that this camera has the potential to produce an
    image as good as a 4 megapixel digital camera with a similar sized ccd? How
    many pixels would this sensor have? Is the image interpolated? What is pixel
    shifting?

  2. According to the press release ...
    http://www.steves-digicams.com/pr/panasonic_06302004_pv-gs400_pr.html
    .... the camera contains 3 x 1/4.7" sensors. Thats VERY small sensors
    indeed, probably only 3 mm large (small). Such small sensors are only
    found in very cheap still cameras. The total area of those three sensors
    would not even approach digital still cameras in the 4 Mpixel class.

    The camera uses "quad density pixel distribution tecnology" to achieve
    4 Mpixels. That sounds very much like interpolation too me. So - it
    is probably the same as the 700x digital zoom - total nonsens.

    Although it might be a very nice camera, I would not guess that it
    will have ground breaking performance at all.

  3. That's rather BIG sensors for Panasonic! They used to use 1/6" sensors
    in their other consumer/prosumer 3ccd camcorders before, and achieved
    better noise levels than the Sony 1/4.7" sensors. See also

    http://www.camcorderinfo.com/conten...th-PV-GS400-3-CCD-40-Megapixel-Camcorder-.htm

    Note that all these 3ccd camcorders from Sony or Panasonic or Canon
    are obsolete: They cost *way* too much for the features they offer.
    This is obsolete technology. Only a true-color/single-chip Foveon
    design will offer effective still and video capture performance.

  4. But those three sensors measure the *full* light spectrum of the
    captured scene, while your "digital still camera in the 4 Mpixel
    class" measures only one third of the light spectrum of the
    captured scene!
    Therefore the 3ccd approach is still much superior compared with
    the inferior mosaic capture of digital still cameras!
    Both technologies are obsolete, but the digicam mosaic capture
    much more so!
    The 3ccd approach is only inferior compared with the full-color
    capture approach of the Foveon sensor.

  5. Go away Guido! It was not my intention to awake the worst of Trolls.
    Please go to sleep under your stone again. Those are tiny detectors
    and your opinions on the uselessness of Bayer sensors are just as
    useless.

  7. It is not George. Guidi is a much older Troll. He probably
    existed already before the dawn of time, back there before
    the big bang.
