And of course it depends on the amount of data you want to clock in. It makes a big difference if you clock in a 27MBit signal or a 27MByte signal. Somehow you also need to process this amount of data or at least shuffle it from the SGPIO port to another interface like USB or ethernet.
There are 2 app notes which realize a camera interface with SGPIO, but on lower data rate:
