>The GPU contains a very sophisticated ISP - the pipeline of image processing to get some raw camera data to pretty JPG's. This pipeline also needs to be 'tuned' to the particular camera and this can take some times (months for a specialised team to do a really good job)
>All the work above needs to be done for each new camera module - and will be done for any camera sold for the Raspi.
