We've been using the ProSilica/AVT GE4900 recently to get super high resolution 16megapixel images at about 3Hz. It's a nice camera, but that resolution tends to demand high performance from the processor.
We have about 45MB/sec of raw image data we have to process. In order to chew through all this data we've been pushing the raw bayer mosaic images onto an NVidia GTX260 GPU and performing colour conversion, gamma correction and even the sensors flat field correction on the GPU at high speed. We also use the GPU to produce reduced size greyscale images for processing and alalysis alongside the regular colour converted image for display. The ability to process such high resolution images using the GPU has really made the difference for this application and it would not be possible without this capability.
