Abstract
An autofocus detecting device includes a jig, a driving member, and a controller. The jig fixes a camera at a preset object distance. The controller controls the camera to capture an image. The controller calculates a resolution of the captured image and determines whether the image resolution reaches a preset resolution threshold value. If the image resolution of the captured image does not reach the preset resolution threshold value, the driving member rotates a lens of the camera, and controller controls the camera to capture a new image. The controller calculates the image resolution of the new captured image and determines if the image resolution of the new captured image reaches the preset resolution threshold value. The controller controls the driving member to rotate the lens until the image resolution of the captured image reaches the preset resolution threshold value or until the lens reaches a maximum focus.
