NAME

   pambayer - interpret Bayer patterns

SYNOPSIS

   pambayer -type={1, 2, 3, 4} [pamfile]

   Minimum  unique  abbreviation of option is acceptable. You may
use double
   hyphens instead of single hyphen to denote  options.  You  may
use white space
   in  place  of  the equals sign to separate an option name from
its value.

DESCRIPTION

   This program is part of Netpbm.

   pambayer reads a Bayer pattern in a 1-deep  Netpbm  image  and
produces a color
   image in PAM RGB format as output.

   A  Bayer  pattern  is  what you get from the optical sensor in
some digital
   cameras. Such a camera doesn’t have a  red,  green,  and  blue
sensor in the
   exact same place for an individual pixel. Instead, it has red,
green, and
   blue sensors laid out in a two dimensional array. The  pattern
in which they
   are  laid  out  is the Bayer pattern. The input to pambayer is
one sample value
   for each of those sensors, so some samples are red,  some  are
green, and some
   are blue.

   The  input  image is a PNM image or PAM image of arbitrary tu-
ple type.
   pambayer looks at only the first plane of the input.

   The output image is a PAM image of tuple type  "RGB",  i.e.  a
standard color
   image. You can convert this to PPM with pamtopnm.

   If  you’re  interested  in just one of the primary colors, use
pamchannel on
   the output of pambayer to extract it.

OPTIONS

   type=n
          This tells which Bayer pattern the input is:

        1
                GBG/RGR/GBG matrix

        2
                RGR/GBG/RGR matrix

        3
                BGB/GRG/BGB matrix

        4
                GRG/BGB/GRG matrix

          This option is mandatory.
