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 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.
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.
