    I noticed a bright dot on my pictures just recently. After I took a
    shot with the len's cap on I found another 3! Two of them are pink,
    one is light green, and the last one is orange. Here is the picture:

    paper: http://www.pbase.com/image/28168168

    I wonder are they just dirty spot on CCD or bad pixels of CCD?

    It's the pixels. Try a shorter shutter speed, though. Hot pixels are more
    likely to show up the longer the exposure time.

    These are hot pixels. I can make every camera I ever used show them by
    forcing long exposure. It is a fact of digital photography. There is nothing
    wrong with your camera unless the same pixels distort the color in normal
    (not long) exposures.

    I can't get a Canon A80 to show them on its longest exposure setting. At least
    not yet.
