Abstract
A lens detection system includes a system chip, and the system chip includes a first lens selection pin and a protocol path pin. A lens detection method includes performing a reset step by the system chip; enabling the first lens selection pin by the system chip; detecting a first lens identification code via the protocol path pin by the system chip; loading first lens data by the system chip and entering a first lens operation mode for controlling an externally connected first lens if the first lens identification code is detected; and disabling the first lens selection pin by the system chip if the first lens identification code is undetected.
