Yes, but it will not be very good resolution or speed. Even old phones from several years ago contain faster and more powerful processors than little AVR or PIC

A micro-controller is not suitable to do image processing.

Depending on the kind of image processing you want to do, you might need to have the complete image uncompressed in memory.
If we suppose your camera is configured for VGA, 8bits per pixels (greyscale) that's already 640*480 / 1024 = 300 kbytes

I am not familiar with PIC, but I doubt you will find a micro-controller with that amount of RAM...

One possibility it to program your cell phone to do the processing. What type of cell phone is it?

welli didnt bought any mobile for this,but it will be cheap Chinese camera phone.so as you say we need to write a mobile application to do processing and take some value and give it to microprocessor?

What micro controller do you want to use?

The Mbed has tons of processing power, ARM based.

Rorcle, 60% complete
AATV, 5% complete
