1022 This driver is DEPRECATED please use the gspca stv0680 module
1023 instead. Note that for the gspca stv0680 module you need
1024 atleast version 0.6.3 of libv4l.
1025
1026 Say Y here if you want to connect this type of camera to your
1027 computer's USB port. This includes the Pencam line of cameras.
1028 See <file:Documentation/video4linux/stv680.txt> for more information
1029 and for a list of supported cameras.
1030
1031 To compile this driver as a module, choose M here: the
1032 module will be called stv680.

2 * STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
3 *
4 * Thanks to STMicroelectronics for information on the usb commands, and
5 * to Steve Miller at STM for his help and encouragement while I was
6 * writing this driver.
7 *
8 * This driver is based heavily on the
9 * Endpoints (formerly known as AOX) se401 USB Camera Driver
10 * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
11 *
12 * Still somewhat based on the Linux ov511 driver.

16 * Free Software Foundation; either version 2 of the License, or (at your

20 * WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY
21 * or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License

25 * along with this program; if not, write to the Free Software Foundation,
26 * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
27 *
28 * History:
29 * ver 0.1 October, 2001. Initial attempt.
30 *
31 * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
32 * function, made more stable (?)
33 *
34 * ver 0.21 Nov, 2001. Added gamma correction and white balance,
35 * due to Alexander Schwartz. Still trying to
36 * improve stablility. Moved stuff into stv680.h
37 *
38 * ver 0.22 Nov, 2001. Added sharpen function (by Michael Sweet,
39 * mike@easysw.com) from GIMP, also used in pencam.
40 * Simple, fast, good integer math routine.
41 *
42 * ver 0.23 Dec, 2001 (gkh)
43 * Took out sharpen function, ran code through
44 * Lindent, and did other minor tweaks to get
45 * things to work properly with 2.5.1
46 *
47 * ver 0.24 Jan, 2002 (kjs)
48 * Fixed the problem with webcam crashing after
49 * two pictures. Changed the way pic is halved to
50 * improve quality. Got rid of green line around
51 * frame. Fix brightness reset when changing size
52 * bug. Adjusted gamma filters slightly.
53 *
54 * ver 0.25 Jan, 2002 (kjs)
55 * Fixed a bug in which the driver sometimes attempted
56 * to set to a non-supported size. This allowed
57 * gnomemeeting to work.
58 * Fixed proc entry removal bug.
