Capturing, processing and transmitting video images

Hi guys,
I'm a newbie here and would like to ask you guys for some advice. I'm currently looking for a microprocessor that can capture video images from a webcam/pin hole camera, process the video (setting the frame rate etc) and then streaming the video images through a wireless chip. May I know if the Propeller microprocessor is able to do all these? If not, do any of you have any recommendations?
Regards,
Mirage

I don't have the same interests... but pretty close. I thought about it for a long time and finally went here:

Terasic is an Altera distributor/development partner.
This is a wonderful, affordable and startlingly clear implementation. Great way to jump into Verilog and FPGAs...and it actually works, first time, with about 10 minutes worth of study. I don't speak Verilog... never saw an FPGA before and I am not a techno wiz.
Don't get the DE1 package... it doesn't support saving to PC, which you will want. There are all kinds of prebuilt utilities in Altera's OBEX... which you can pay through the nose for[noparse]:)[/noparse]
I'm doing this while I'm waiting for the Prop II and more RAM in addition to what comes on the PropII...or a serial camera from either Parallax or 4D Systems.
Consider all of the intellectual property you need to command if you want to go this particular FPGA route commercially: You don't even have the right to use the software you paid for... for commercial purposes, without some kind of further agreement[noparse]:)[/noparse] Thats a real killer for a small company.

I agree with Mike about the memory, but I guess that depends on what you are doing for processing. If you want to save full frames in memory, no luck there. If, however, you could have some sort of FIFO setup where a stream of data is coming in from a camera and going out immediately to a wireless device, then you might be able to do that. The frame rate will not be good and one little hickup on the wireless will slow down image transfer.

Still weighing all the possible options for now...
However, I think there wasn't many resources left and it was running at a fairly low resolution and colour depth.
