Optical systems having at least one polarization beam splitter (PBS) are operable to receive randomly-polarized light bundles from a projector lens. The PBS is further operable to direct light bundles having a state of polarization (SOP) along a light path and operable to direct other light bundles having a different SOP along different light paths. The light paths have optical path lengths which may differ. Each light path produces an image having a distortion which may differ from the distortion of an image produced by a different light path. A compensation in a light path is operable to convert a non-compensated distortion of an image into a compensated distortion that more closely matches the distortion of images in other light paths.

Systems are presented with special mechanical means to switch a set of lens elements to form a compound lens from a storage position to an imaging position. In the storage mode, these arrangements offer highly efficient space saving schemes suitable for use in application where space is a premium. In the imaging mode, a plurality of lens singlets are brought together on a common imagine axis whereby they operate to form very high quality images at a single image plane. Singlet lenses are held in a lens mount device of a disk element. A plurality of similar cooperating disk elements move against adjacent coupled disks to cause well-regulated desirable motion and positioning. Specifically, portions of the disk include a cam system which permits smooth movement as disk elements are counter rotated with respect to each other thus driving the preferred positioning.

The controller is configured to derive the angle in accordance with the predetermined distance and the position information of the object, and the controller is configured to control the zooming module to move in accordance with the angle.

A self-aligning lens holder includes elements that register against an image sensor chip to align the holder and lens with the chip. The elements may deflect or deform. A corresponding method aligns the lens holder and a fisheye lens to the image sensor.

An imaging apparatus comprising: a subject recognition section for recognizing a subject image at rest on an imaging surface and a subject image moving on the imaging surface, an image shift-amount detection section for detecting a positional shift on the imaging surface, and an image composition section for executing composition processing by additive composition of the respective image data if the subject recognition section recognizes the subject image as the subject image at rest on the imaging surface and for correcting the positional shift of the moving subject image detected by the image shift-amount detection section if the subject recognition section recognizes the subject image as the subject image moving on the imaging surface and then, for executing the composition processing by relatively bright composition or additionally averaged composition of the respective corrected image data so as to generate taken image data with multiple exposure.

A lens barrel includes: a lens frame that holds a lens and is movable in the optical axial direction of the lens; and a moving mechanism that moves the lens frame in the optical axial direction. The moving mechanism includes: a feed screw; a drive source that rotates the feed screw; a biasing member that biases the lens frame toward direction side; a nut on the direction side of the lens frame that is screwed with the feed screw; and a low-friction member between the nut and the lens frame in the optical axial direction. At least one of a friction coefficient between the lens frame and the low-friction member or a friction coefficient between the nut and the low-friction member is smaller than a friction coefficient between the lens frame and the nut when the lens frame is in contact with the nut.

The present disclosure provides a method for suppressing vibration noises of a camera in an electronic device, wherein the electronic device at least comprises a housing, and an acoustic actuator and a camera accommodated in the housing, and the acoustic actuator drives the electronic device to vibrate and sound; the camera is a zoom lens and comprises a movable component and a fixed component, and the method comprises the following steps of: S1: detecting whether the acoustic actuator is in a vibrating state, performing S2 if the acoustic actuator is in a vibrating state; otherwise, ending the step; S2: generating a drive current according to a relative position relationship between the movable component and the fixed component to drive the movable component to move until abuts against the fixed component and tightly presses the movable component; and S3: repeating S1.

An SMA actuator (10) comprising SMA wires (31, 32) in which the wire arrangement is asymmetrical, allowing a greater range of motion from a rest position in a first direction than in a second direction, which may be opposite or orthogonal to the first direction. Where the directions are opposite, the angle between a principal axis and the wires providing motion in the first direction may be different from the angle between the principal axis and the wires providing motion in the second direction.
