Linux OV511 Driver:
Technical Notes Vol. 2
Subject:  Detection of Image Sensors
2000/12/24, driver version 1.29 (experimental)

The following table describes the "signatures" of the various image sensors used in conjunction with the OV511/OV511+. These are used in my driver to determine the sensor type. I still don't know how to differentiate between the color (OVx6xx) and black & white (OVx1xx) sensors (2003/02/13: OV confirms that it is impossible).

The OV8600 is an 800x600 (SVGA) sensor, and is not publically documented or in use yet.
