Control an USB Cam?


I got this "OEM" Cam: http://www.delock.de/produkte/729_Ka...setLanguage=en
The Company where I often buy thinks from told me its possible to Control the Cam via USB via the "Standard SCCB interface (IC Bus)" I got an Sheet from the Company who produce the Chip which commands I have to send over an Pin who is not accessible via the Board to turn the Cam into an Black and White Mode.
I know there is Software who turn the Image from the Cam into B/W Mode but that is not what I want.
So is there any Software who work lets say in Suse who allow me to switch the Cam into B/W mode and take Pictures?
Thanks

That is a v4l2 camera. It has a standard Linux kernel interface. So, any program that controls a web cam should be able to do what you want. You can try 'cheese' and 'Qtcam'.

From the command line there's uvcdynctrl and v4l2-ctl to list and change various settings for UVC class compliant devices (most usb cameras). Tools like guvcview are good for putting many of those options in a gui.

The SCCB stuff is from the I2C bus, not USB and is different.

http://www.rpg.fi/desaster/blog/2012...ensor-success/

The feature list on that item didn't list a B&W mode. But there's various ways to convert images to B&W. Even video streams. IR in this case probably means that the IR filter that is built into most cameras is not there. So its more sensitive (but not color accurate) in low light situations, or in the presence of an IR light source (night mode for security cameras).

Delock told me to use the SCCB Interface.
The only Port who available is the USB interface.
I found this: https://cdn.sparkfun.com/datasheets/..._datasheet.pdf

And how to use the software who you recommend?

The SCCB interface might be controlled through the USB interface. Does this camera actually plug into a USB port? Can you see anything through it in cheese? SuSE might not have a Qtcam package.

OK, in cheese there is a button box marked 'effects'. See if B&W is one of the effects.

cheese doesn't do rendering. Why do you think cheese doesn't control the camera? Is black and white present under effects? You can also try gtk-v4l.
