Re: debayer implementation.

We would like to contribute it to ImageMagick if it may be useful for
others.

Our goal is to make it as flexible as possible.

The original debayers we took are from
http://libdc1394.svn.sourceforge.net/viewvc/libdc1394/trunk/libdc1394/dc1394/bayer.c?revision=535&view=markup

We modified it slightly to match our images format and we are working now on
a in-debayer HDR based on the 2 Green channels we have from the sensor. This
method gives limited improvement (I believe 3-5 times) and is specific to
the CMOS sensors with on-chip ADC as with CCD it is just possible to use
higher dynamic range ADC and don't use variable "analog gains" at all.

Best regards,
Alexandre Poltorak
