Abstract:
A camera module includes a lens assembly, a lens holder, and an image sensor assembly. The lens assembly includes a lens barrel and multiple lens elements embedded within the lens barrel. A change of temperature causes an optical focal shift that is determined according to an optical thermal shift rate associated with an optical design of the lens assembly. The lens holder has a lens holder CTE to compensate for the optical focal shift by thermo-mechanical expansion. The change of temperature causes a length expansion of the lens holder determined at least in part according to the lens holder CTE. The image sensor assembly includes an image sensor and a substrate coupled to the image sensor, the image sensor to capture light passing through the multiple lens elements and convert the captured light into image signals. The lens holder is attached to the lens barrel and the substrate using adhesives.
Abstract:
Various embodiments include a damper arrangement that may be used to dampen motions of a dynamic component. In some embodiments, the damper arrangement may be used in a camera module that includes a stationary component and a dynamic component. For instance, the dynamic component may hold a lens such that the lens moves together with the dynamic component. In various examples, the damper arrangement may include an interface member that extends from the stationary component or the dynamic component to at least partially into a viscoelastic material within a pocket configured in the stationary component, the dynamic component, or both. The interface member may be configured to traverse within the viscoelastic material to dampen motion of the dynamic component, for example, during operation of a lens actuator to move the dynamic component along an optical axis of the lens.
Abstract:
A camera system may include a first camera unit and a second camera unit. The first camera unit may include a first actuator. The second camera unit may include a second actuator. The first actuator may move one or more components of the first camera unit to provide autofocus and/or optical image stabilization functionality to the first camera unit. The second actuator may move one or more components of the second camera unit to provide autofocus and/or optical image stabilization functionality to the second camera unit. In some examples, the first camera unit may be configured to capture a first image of a first visual field. The second camera unit may be configured to capture, simultaneously with the first camera unit capturing the first image, a second image of a second visual field.
