A sensor actuator includes a first movable body on which an image sensor having an imaging plane is disposed, a second movable body spaced apart from the first movable body in a direction perpendicular to the imaging plane, a fixed body accommodating the first movable body and the second movable body, and a driver configured to provide driving force to the first movable body, wherein the first movable body and the second movable body move together in a direction parallel to the imaging plane, and the first movable body rotates relative to the second movable body.

A lens driving device is disclosed that includes two movers, a long quadrangular frame body, at least two coils and an FPC. The movers are arranged side by side and provided with a through hole for accommodating a lens body, respectively. The frame body surrounds an outer periphery of the two movers. The two coils face one mover of the two movers and are fixed to two long sides of the frame body. The FPC includes coil connecting terminals electrically connected to the two coils.

The present invention provides an optical lens and an assembly method thereof The optical lens includes: a first lens barrel; a second lens barrel arranged with a first mounting portion protruding toward the first lens barrel; a first lens, comprising a first object side facing a light incident end of the optical lens, a first image side facing a light exit end of the optical lens, and a first side wall connecting the first object side and the first image side; wherein the first lens is sandwiched between the first lens barrel and the second lens barrel; the first mounting portion is arranged around the first lens and spaced from the first side wall to define a glue-holding slot; a first adhesive material, arranged between the first image side and the second lens barrel; and a second adhesive material, arranged in the glue-holding slot. In this way, the first lens can be prevented from deforming or breaking, i.e., the lateral shear strength of the optical lens can be improved.

Embodiments of the present disclosure further relate to a camera device assembled such that to reduce (and in some cases minimize) auto-focusing actuation power when the camera device operates in a macro mode. The camera device includes an image sensor and a lens assembly in an optical series with the image sensor. During manufacturing of the camera device, the lens assembly is assembled within the camera device to have an optical axis substantially parallel to gravity and positioned to have an offset along the optical axis. The offset is determined during manufacturing of the camera device such that, when the camera device is in the macro mode, the lens assembly is positioned at a neutral position relative to the image sensor without actuation applied to the lens assembly.

An optical system includes a fixed module, a movable module and a driving assembly. The movable module moves relative to the fixed module, and the movable module includes a lens unit which includes a first lens, a second lens, a first side wall and a second side wall. The first side wall has a first surface, which directly contacts the second lens, and the second side wall directly contacts the first lens. A portion of the driving assembly is directly disposed on the lens unit, configured to drive the lens unit to move along an optical axis of the first lens. The first side wall further has a second surface opposite to the first surface, and the second surface directly contacts the portion of the driving assembly. The thickness of the first side wall is different from the thickness of the second side wall.

A lens apparatus includes a first barrel member including a first helicoid screw on an inner surface included therein, a second barrel member including a second helicoid screw, screwed with the first helicoid screw, on an outer surface included therein, the second barrel member being movable along a direction of an axis of the first barrel member, an urging member configured to urge the second helicoid screw against the first helicoid screw in a direction of a diameter of the first barrel member, and a third barrel member including an outer surface which has a diameter smaller than a diameter of the second helicoid screw. The urging member is held by the second barrel member inside the second barrel member, and is in contact with the outer surface of the third barrel member.

A vehicular camera includes a PCB having an imager disposed thereat, a lens barrel accommodating a lens, and a lens barrel support structure that protrudes from the PCB and at least partially circumscribes the imager. The lens barrel has an outer surface between the ends of the lens barrel. The outer surface of the lens barrel is adhesively bonded to an inner surface of the lens barrel support structure via adhesive. The outer surface of the lens barrel opposes the inner surface of the lens barrel support structure. With the adhesive in its uncured state and contacting the opposed surfaces, the imager is aligned with the lens accommodated at the lens barrel. With the imager aligned with the lens, the adhesive is cured to adhesively attach the lens barrel at the lens barrel support structure.

An optical lens system is provided with at least two lenses firmly bonded to each other. A first lenshas a first adhered surface and a second lens has a second adhered surface. The adhered surfaces are at least indirectly firmly bonded to each other. An optically transparent surface body made of a silicone material is arranged between the adhered surfaces. The first adhered surface is firmly bonded to a first side and the second adhered surface is firmly bonded with the opposite second side of the sheet body by means of a bonding method.

The various implementations described herein include a camera device that includes: (1) a housing; (2) an image sensor positioned within the housing and having a field of view corresponding to a scene in the smart home environment; (3) at least one infrared (IR) illuminator positioned with the housing, the IR illuminator configured to selectively illuminate the scene; and (4) a front face that is at least partially concave-shaped and coupled to the housing, the front face positioned in front of the image sensor such that light from the scene passes through the front face prior to entering the image sensor, and the front face positioned in front of the IR illuminator such that IR light from the IR illuminator is directed through the front face.

Misalignment of a substrate portion which integrates an image sensor and a substrate is suppressed. An imaging apparatus comprises: an imaging optical system including at least one optical element; a holding member holding the imaging optical system; an image sensor configured to capture a subject image formed by the imaging optical system; a substrate having the image sensor mounted thereon; and a bonding member fixing a substrate portion to the holding member, the substrate portion integrating the image sensor and the substrate, wherein the bonding member is partly in contact with a surface of the substrate portion, and at at least two positions in a part of the surface of the substrate portion in contact with the bonding member, the surface of the substrate portion faces different directions.
