Abstract
The present invention discloses an optical system with multiple optical lens having capability of auto-focus calibration, instead of conventional scheme of manual operations. Furthermore, achieve purpose of obtaining more accuracy in sharpness and magnification calibration than the conventionally scheme, and of upgrading yield rate of the system. The optical system disclosed by the invention basically includes a lot of home-sensors and micro-sensors, lots of lens, an image sensor, an imaging control motor, a lens switch motor for switching the lens, and a base control motor for switching base of the optical system. By using the imaging control motor and the base control motor to control motions of the imaging device and the lens, auto sharpness and magnification calibration is easily achieved.
