Hi,
Can somebody tell me something about the realization of the arithmetic about the
Auto focus of CMOS Image sensor.

THANKS!
 

If I am not wrong, autofocusing on cameras are software issue, meaning it's the microprocessor that calculates the focusing and feedback to the lens, which in turn adjusts the distance between various lens glasses, creating a feedback loop.
 

OmniVision (www.ovt.com)just buy a company to develop this technology!
