Embodiment Construction

[0038] All figures described next are drawn in a three-axis (X-Y-Z) frame of reference, where the axes are defined as follows: the Z-axis is parallel to the optical axis of the two lens modules and perpendicular to the surface of the camera sensor. The Y axis is perpendicular to the optical axes of the two lenses and parallel to the camera sensor surface. The Y axis is also perpendicular to the shortest line connecting the optical axes of the two lens modules. The X-axis is perpendicular to the optical axes of the two lenses, parallel to the camera sensor surface and parallel to the shortest line connecting the optical axes of the two lenses.

Abstract

Dual optical module autofocus (AF) or AF+optical image stabilization (OIS) camera with reduced coverage and reduced mutual magnetic interference. Some AF+OIS cameras may include a single AF actuation assembly that moves both lens barrels in unison. Some AF cameras or AF+OIS cameras may have two AF actuation subassemblies and associated magnets for independent AF operation of each lens barrel, the magnets to eliminate the AF actuation of one AF actuation subassembly to the other The manner in which the magnetic influence of the subassemblies is shared allows the two lens barrels to be positioned in close proximity, saving components and manufacturing costs.

Description

[0001] Cross References to Related Applications [0002] This application is related to and claims priority to U.S. Provisional Patent Application No. 62 / 141875, filed April 2, 2015, and having the same title, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments disclosed herein relate generally to dual voice coil or multi-voice coil motor (VCM) structures, and specifically to dual VCM structures for use in miniature dual optical modules or multi-module cameras. Background technique [0004] Compact (tiny) dual optical module cameras (also known as "dual aperture cameras", "dual lens cameras" or simply "dual cameras") (eg, as in smartphones) can be used in conjunction with appropriate computational photography algorithms , for several purposes. These include enabling advanced digital zoom, reducing overall module height while maintaining high performance, improving low-light performance and creating depth maps. In order t...
