Abstract:
Techniques and apparatuses are described that enable non-canting VCM-actuated autofocus. These techniques and apparatuses enable multiple focal distances that are substantially free of imaging errors caused by canting of a lens housing. These multiple focal distances are provided by multiple positions of a lens housing relative to an image sensor. These positions can be free of cant through use of mechanical stops and corresponding mechanical stop-mates. By so doing, lower cost, faster focusing, higher image quality, lower power, or lower settling time can be achieved.
