Scanning type automatic-focusing detected image capturing apparatus

The utility model discloses a scanning type automatic-focusing detected image capturing apparatus which comprises a scanning type image capturing unit, an automatic focusing operating module and a focusing motor, wherein the scanning type image capturing unit comprises a lens and a linear charge coupling device, and continuously moves relative to a platform so as to utilize the linear charge coupling device to capture a plurality of continuous linear images from an object to be detected; the automatic focusing operating module combines the continuous linear images into a detected image, analyzes the image and generates a focusing control signal so as to enable the focusing motor to drive the lens to move to a focusing position along a focusing path vertical to the platform when the scanning type image capturing unit continuously moves relative to the platform.
