MT9M001 CMOS sensor interface to AT91SAM9263

[bhuviram]

I am trying to interface two MT9M001 CMOS sensor using ISI interface in ARM. I would really appreciate if I could get some input:
1)Both CMOS sensor have same address and how to interface it using I2C
2) Should I use any buffer between processor and data, vsync,hsync and pclk lines to isolate(tristate) the camera output or just by toggling OE can I eliminate it.

Thanks

Does anyone has experience interfacing two CMOS MT9M001 sensor on ISI for ARM. I would really appreciate your feedback on the hardware.
