ABSTRACT:
The specification and drawings present a new method, apparatus and software product for a single motor/actuator adjustment of two assemblies (e.g., for performing zoom and auto-focus functions) for image adjustment using a clutch unit (e.g., a switch) in image adjustment modules of electronic devices. The clutch unit can be used to engage one of two lead screws having a common axis one at a time with a driving shaft (e.g., having the same common axis), so these two lead screws can operate independently in order to provide adjustments of the two assemblies.
