Question: A project I'm working on involves wireless transmission of images from a camera to a host computer in real time. Can the Raspberry Pi be used as a [DSP](http://en.wikipedia.org/wiki/Digital_signal_processor) for the camera for image acquisition and pre-processing?

Answer: 
The [OpenMAX API](http://www.khronos.org/openmax/) is available on the Raspberry Pi. It handles audio and video encoding/decoding, [for example, JPEG](http://www.raspberrypi.org/phpBB3/viewtopic.php?f=33&t=15463&hilit=decoding%20image%20with%20openmax).

The eLinux wiki lists other [APIs usable on the Raspberry Pi](http://elinux.org/RPi_VideoCore_APIs):s graphic processor.

Pierre has worked on image processing on Rpi. I think you will find the mentioned tutorials helpful iff you have a prior knowledge of languages.
