Abstract: A digital stereograph-capturing device is provided by the present invention including a first objective lens set and a second objective lens set adapted for receiving optical signals outside the stereograph-capturing device into said device, a shutter-switching unit, an image sensor, an image processor and a storage unit. The shutter-switching unit has a rotatable first reflecting mirror, a rotatable second reflecting mirror and a prism, thereby allowing only the pass of the optical signal received by the first objective lens set through said first reflecting mirror and the prism within an independent period of time, and allowing only the pass of the optical signal received by the second objective lens set through the second reflecting mirror and the prism within the other independent period of time. The image sensor is used to detect the optical signals passed through the shutter-switching unit. The image processor is used to transform the optical signals detected by the image sensor into corresponding digital signals. The storage unit saves the digital signals.

Abstract: An imaging lens module includes an imaging lens unit, an optical folding component and a sensing magnet group. The imaging lens unit has an optical axis. The optical folding component is configured to fold an incident optical path into the imaging lens unit to coincide with the optical axis. The sensing magnet group includes two sensing magnets that are sequentially disposed on the imaging lens unit along a direction in parallel with the optical axis. The sensing magnets are located at the same side with respect to a reference plane that passes through the optical axis and has a normal direction perpendicular to the optical axis. When the sensing magnets are observed from the direction in parallel with the optical axis, images of the sensing magnets are at least partially overlapped. Two adjacent magnetic poles of the sensing magnets are like poles between which there is a repulsive force.

Abstract: A lens driving module is configured to provide an imaging lens system with auto-focus functionality. The imaging lens system is disposed between a preloading element and a driving base of the lens driving module. The preloading element includes an injection molded part and a ferromagnetic part partially embedded in the injection molded part. A rollable element is disposed in each of mounting structures of the injection molded part and in contact with a displaceable lens carrier of the imaging lens system. The ferromagnetic part and a magnet disposed on the displaceable lens carrier together generate a magnetic attraction force, such that the displaceable lens carrier exerts a preloading force on the rollable element. The driving base includes a driving coil and an electrical wiring pattern. The driving coil corresponds to the magnet for generating a driving force to drive the displaceable lens carrier to move along the optical axis.

Abstract: An imaging lens module with auto focus function includes an imaging lens assembly, an electromagnetic driving component assembly and a lens carrier. The imaging lens assembly has an optical axis. The electromagnetic driving component assembly drives the imaging lens assembly to move in a direction parallel to the optical axis by a Lorentz force. The imaging lens assembly is mounted to the lens carrier such that the imaging lens assembly can be wholly driven by the Lorentz force. The lens carrier includes an object-side part, a mounting structure and a plurality of plate portions. The object-side part includes a tip-end minimal aperture configured for light to travel through; and a tapered surface which surrounds an area tapered off from image side to object side. The mounting structure and the plate portions are configured for at least a part of the electromagnetic driving component assembly to be mounted thereto.
