CONTINUOUS AUTOFOCUS MECHANISMS FOR IMAGE CAPTURING DEVICES
First Claim
1. A method to implement a continuous autofocus mechanism for an image capturing device, the method comprising:
- performing an autofocus scan that positions a lens of the image capturing device in a plurality of positions;
obtaining a plurality of focus scores with each focus score being associated with a respective lens position of the autofocus scan; and
determining an acceptable band of focus scores based on the obtained plurality of focus scores.

Abstract
At least certain embodiments described herein provide a continuous autofocus mechanism for an image capturing device. The continuous autofocus mechanism can perform an autofocus scan for a lens of the image capturing device and obtain focus scores associated with the autofocus scan. The continuous autofocus mechanism can determine an acceptable band of focus scores based on the obtained focus scores. Next, the continuous autofocus mechanism can determine whether a current focus score is within the acceptable band of focus scores. A refocus scan may be performed if the current focus score is outside of the acceptable band of focus scores.
