Thanks Francescato Diego and Clive.

I was pushed to work this way as the hardware is already designed and I have to just write firmware for it. Yes, I have no issue with the SD card speed as far as rest of the project requirement. I achieved 3Mb/s tested today. Yes I was thinking about NAND memory and compression algorithms before I started to attempt this project but cost was an issue as this (DCMI to SD) is a part of that project. Any how I have one more idea I'll try that. I'll try to capture odd and even fields I think interlacing is the word for it. I'll update that if I have done it like this.... Cheers.. :)

@ali.babar

Did you manage to get any further with this high bandwidth DCMI > SDIO concept? I am looking to achieve similar (without external memory).

It would be handy to know what type of throughput you managed to achieve?

I am looking at splitting it up and receiving parts of the frame over multiple frames (as camera has function to repeat frames) if the throughput is not possible.
