Abstract
A method of focusing a digital camera module with an image sensor including capturing an image of a test target with the digital camera module, determining a focus quality of the image with the image sensor, outputting a signal related to the focus quality of the image from the digital camera module to a focusing station external to the digital camera module, and determining whether a position of a lens from the image sensor within the digital camera module should be altered to improve a focus quality of subsequently captured images.
