IMAGE CAPTURE USING A MICROCONTROLLER

[ap.lopes]

Morning! i'm making a school work related with image capture using a microcontroller. This work is totally new for me, reason why i'm having some difficulties. It consists in the using of a digital camera with 640 x 480 pixels resolution (VGA), that reads 30 frames per second. The microcontroller PIC24f is connected with a SD card where the data is stored. I ask if it is possible to record directly the data in the SD card or if it is necessary a memory RAM connected to the microcontroller and what type?
I really appreciate any clarification.
