    Thank you for the information Mr Erel,
    Erm if just want to recognize the majority colour of the picture in certain time interval or
    if i want to use the camera to read the UART data from maybe colour LED generate by microcontroller.(Just doing experiment)
    is that possible to do that?
    What should i study ?
    Thank you very much.

    You can convert the preview image to a standard Bitmap and then go over the bitmap pixels. It will probably be too slow for anything useful.

    How is the preview converted into a bitmap?
