I don't know if it will easily interface to your PIC, but I used a IDT
7205
FIFO to capture sub-windowed images from a camera. Once a sub-frame is in
the FIFO, you can read it out non-destructively for multiple passes at the
data. Gruesome, but better than nothing.

Gruesome? How would you rate the following?

An 8051 connected to an SRAM chip of 256kbyte, together with a CPLD and an
ADC. To capture an image, the 8051 would toggle a pin on the CPLD and then
go into power down mode. The CPLD detected the power down mode (which also
floats the 8051's bus pins), took over the SRAMs address bus, enabled the
ADC on the databus and pumped an image from ADC to SRAM at a fixed location.
When the transfer was complete, the CPLD floated it's bus pins, disabled the
ADC and interrupted the 8051 from power down mode back to life.....
