* sn9c2028-decomp.c
|
||||
*
|
||||
* Decompression function for the Sonix SN9C2028 dual-mode cameras.
|
||||
*
|
||||
* Code adapted from libgphoto2/camlibs/sonix, original version of which was
|
||||
* Copyright (c) 2005 Theodore Kilgore <kilgota@auburn.edu>
|
||||
*
|
||||
* History:
|
||||
*
|
||||
* This decoding algorithm originates from the work of Bertrik Sikken for the
|
||||
* SN9C102 cameras. This version is an adaptation of work done by Mattias
|
||||
* Krauss for the webcam-osx (macam) project. There, it was further adapted
|
||||
* for use with the Vivitar Vivicam 3350B (an SN9C2028 camera) by
|
||||
* Harald Ruda <hrx@users.sourceforge.net>. Harald brought to my attention the
|
||||
* work done in the macam project and suggested that I use it. One improvement
|
||||
* of my own was to notice that the even and odd columns of the image have been
|
||||
* reversed by the decompression algorithm, and this needs to be corrected
|
||||
* during the decompression.
