tristate "USB W996[87]CF JPEG Dual Mode Camera support"
depends on USB && VIDEO_DEV && I2C
---help---
Say Y here if you want support for cameras based on
Winbond W9967CF/W9968CF JPEG USB Dual Mode Camera Chips.
This driver has an optional plugin, which is distributed as a
separate module only (released under GPL). It contains code that
allows you to use higher resolutions and framerates, and can't
be included into the official Linux kernel for performance
purposes.
At the moment the driver needs a third-part module for the CMOS
sensors, which is available on internet: it is recommended to read
<file:Documentation/usb/w9968cf.txt> for more informations and for
a list of supported cameras.
This driver uses the Video For Linux and the I2C APIs.
You must say Y or M to both "Video For Linux" and
"I2C Support" to use this driver.
Information on this API and pointers to "v4l" programs may be found
on the WWW at <http://roadrunner.swansea.uk.linux.org/v4l.shtml>.
This code is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called w9968cf.o. If you want to compile it as a
module, say M here and read <file:Documentation/modules.txt>.
