    Default Pentax-Microsoft entered Into a Patent Cross-Licensing Agreement

    Pentax is apparently compensating Microsoft.

    I wonder what specific technology is in scope.

    With Bill Gates involved...who knows?
    My guess its more likely software interfacing. Imagine pentax K50D running on windows mobile 10.0 You may need to reset your camera once in a while and load anti-virus software! For the immediate need, more likely built in connectivity and synchronisation and built in full image processing....?

    Samsung is in the list of companies too.

    Wonder is it becoz Pentax partnership with Samsung, that's why Pentax is "boarding" the ship too.
    Let's get rolling :)

    Consider Microsoft is main role in world computer monopoly. Maybe Pentax may be big like Microsoft one day and overbeat Nikon and Canon in photo monopoly one day????

    Rumour is it is for a new jpeg standard from Microsoft called JPEG XR to replace the existing jpeg format

    Extract from last article:

    JPEG XR will be used in a much larger, mainstream photography market. DNG and raw, in comparison, appeal chiefly to professionals and advanced amateurs today, and no matter how easy processing those images may become once downloaded from a camera, any amount of processing will rule out a large population.

    JPEG XR does address one advantage of raw and DNG, the ability to preserve more of the original data from image sensors. JPEG retains 8 bits of data for the blue, red and green in each pixel, but cameras typically record 12 bits, with Canon's new 1D Mark III recording 14 bits and higher-end models 16 bits.

    JPEG XR, though, has immense bit depth--with 16 or 32 bits of data recorded for each pixel's color, that means somewhere between 65,536 and 4,294,967,296 shades of tonal variation between black and white. Thus the "XR," or extended range, moniker. Regular 8-bit JPEG has 256 shades, which is plenty if they happen to be distributed perfectly, but not enough if you want to use photo-editing software to brighten up a face that's lost in shadow.

    However, DNG and raw formats offer something JPEG XR can't: unprocessed data. Creating a JPEG XR image means the camera is making its best guess about color balance--compensating for the bluish hue of fluorescent lights or the orange cast of incandescent, for example--as well as reducing noise and sharpening edges. For those who want that level of control, stick with raw or DNG.
