Dead pixels on Olympus C4000

    I have recently discovered a problem with my Olympus C4000.
    Every picture I now take includes a small white dot. On magnification
    at 16x this appears to be 4 square pixels.

    I have yet to change the smart media card, but as the lens is clean,
    I believe this may be pixel failure on the CCD. Does anyone know the
    expected lifespan of a charge coupled device, and will the problem get
    worse? Is there anything else I can do or try? Thanks in advance.

    As my camera is just within one year old I am emailing my vendor where
    I purchased the camera from.

  2. Use the Pixel Mapping feature in the cam. Page 164 of the PDF manual
    that came on your C4000 CD. It's a side-effect of the digital sensor
    technology to have this happen. As far as I know they have not made
    any digital camera immune to it. Pixel Mapping is a way around it.
    Lots of people would be returning their cams if they didn't include
    the feature.

    Yup... that's the reason I bought an Olympus. Only Olympus has the built-in
    pixel mapping function. Other makers, like Canon, don't have it. That means
    when the Canon develops hot pixels, you're stuck with it, or stuck with $$$
    getting it repaired. I don't know why other makers don't have pixel
    mapping... perhaps it's patented or something. I've heard there's a hack for
    some Nikon models, where you can tell it to pixel map if you have it hooked
    up to a PC.
