SYNOPSISpambayer -type={1|2|3|4} [pamfile]
Minimum unique abbreviation of option is acceptable. You may use dou‐
ble 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(1).
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 pat‐
tern 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 tuple 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(1).
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.
