STM32F4 DCMI and OV9655 Partial Image Read

Hello,

I started using STM32F4DIS-BB and DIS-CAM module with STM32F4Discovery board. Examples found on web displays camera image on LCD through DMA transfer. But in my project, I will not use LCD. 320x240 pixel image consumes 150kb RAM, it is a big problem. To overcome this issue, i would like to read image partially ( maybe line by line) and store it on SD card. Is this possible? How can i request image as lines from DMA?

Sorry, i am a beginner. I need your help.

Thank you
