- Say Y here if you want to connect this type of camera to your

- See <file:Documentation/video4linux/stv680.txt> for more information

- * STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
- *
- * Thanks to STMicroelectronics for information on the usb commands, and
- * to Steve Miller at STM for his help and encouragement while I was
- * writing this driver.
- *
- * This driver is based heavily on the
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.
- *
- * This program is free software; you can redistribute it and/or modify it
- * under the terms of the GNU General Public License as published by the
- * Free Software Foundation; either version 2 of the License, or (at your
- * option) any later version.
- *
- * This program is distributed in the hope that it will be useful, but
- * WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY
- * or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License

- *
- * You should have received a copy of the GNU General Public License
- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History:
- * ver 0.1 October, 2001. Initial attempt.
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- * function, made more stable (?)
- *
- * ver 0.21 Nov, 2001. Added gamma correction and white balance,
- * due to Alexander Schwartz. Still trying to
- * improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001. Added sharpen function (by Michael Sweet,
- * mike@easysw.com) from GIMP, also used in pencam.
- * Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- * Took out sharpen function, ran code through
- * Lindent, and did other minor tweaks to get
- * things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs)
- * Fixed the problem with webcam crashing after
- * two pictures. Changed the way pic is halved to
- * improve quality. Got rid of green line around
- * frame. Fix brightness reset when changing size
- * bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- * Fixed a bug in which the driver sometimes attempted
- * to set to a non-supported size. This allowed
- * gnomemeeting to work.
- * Fixed proc entry removal bug.
