SYNOPSIS

DESCRIPTION

14       This program is part of Netpbm(1).
15
16       pambayer  reads a Bayer pattern in a 1-deep Netpbm image and produces a
17       color image in PAM RGB format as output.
18
19       A Bayer pattern is what you get from the optical sensor in some digital
20       cameras.   Such  a camera doesn't have a red, green, and blue sensor in
21       the exact same place for an individual pixel.   Instead,  it  has  red,
22       green,  and blue sensors laid out in a two dimensional array.  The pat‐
23       tern in which they are laid out is the Bayer  pattern.   The  input  to
24       pambayer is one sample value for each of those sensors, so some samples
25       are red, some are green, and some are blue.
26
27       The input image is a PNM image or PAM image of  arbitrary  tuple  type.
28       pambayer looks at only the first plane of the input.
29
30       The  output  image is a PAM image of tuple type 'RGB', i.e.  a standard
31       color image.  You can convert this to PPM with pamtopnm(1).
32
33       If you're interested in just one of the primary colors, use  pamchannel
34       on the output of pambayer to extract it.

OPTIONS

39       Minimum  unique abbreviation of option is acceptable.  You may use dou‐
40       ble hyphens instead of single hyphen to denote options.   You  may  use
41       white space in place of the equals sign to separate an option name from
42       its value.
