    The lines where the patent departs from reality are 0060 and 0061.

    Getting RGB sensors which do not also have IR response requires a
    different type of filter material than is currently used. At present
    most cameras have an IR filter in front of the sensor to avoid IR
    bleeding into the other colours. Famously, Leica came to grief on their
    M8 over this precise issue, when they left the IR filter out - scroll
    down to the section on "Infrared / Ultraviolet pollution" on this page:
    http://www.dpreview.com/reviews/leicam8/page15.asp
    The only solution to this IR bleeding was to put an IR filter on any
    lens used with the M8 - which would, of course, mean the Olympus AF
    wouldn't work. Leica fixed the problem with the M9, by fitting an IR
    filter to the sensor, just like everyone else does.
    Make your choice - an overly complex AF system or consistent colour. ;-)
