LPC family general performace, capturing and storing image?

I have question regarding general performance of LPC (21xx, 22xx to be exact) family. I am thinking of building some kind of car camera that would continuously capture images of what is happening on the road in last 5-10 minutes and store them on sd card (images recorded after 5-10 minutes are overwritten by new images). Is LPC family capable of capturing and saving to SD card 320x240 BW images @ 20FPS? If not, what MCU are you suggesting?

Thanks in advance!
