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.

An optical article, such as a spectacle lens, includes, on a substrate, a photochromic layer containing a photochromic dye and a resin component, and a protective film. The indentation hardness of the photochromic layer in the thickness direction is less than or equal to the indentation hardness of the surface of the substrate. The result of multiplying the indentation hardness of the protective film in the thickness direction and the thickness of the protective film is five-hundredths or more times and one or less times the result of multiplying the indentation hardness of the photochromic layer in the thickness direction and the thickness of the photochromic layer.

An imaging element incorporates a reading portion that reads out captured image data at a first frame rate, a storage portion that stores the image data, a processing portion that processes the image data, and an output portion that outputs the processed image data at a second frame rate lower than the first frame rate. The reading portion reads out the image data of each of a plurality of frames in parallel. The storage portion stores, in parallel, each image data read out in parallel by the reading portion. The processing portion performs generation processing of generating output image data of one frame using the image data of each of the plurality of frames stored in the storage portion.

The technology of this application relates to a zoom lens, a camera module, and a mobile terminal. The zoom lens includes a plurality of lens groups, for example, a first lens group, a second lens group, a third lens group, a fourth lens group, and a fifth lens group that are arranged from an object side to an image side. The first lens group is a lens group with a positive focal power, the second lens group is a lens group with a negative focal power, and the third lens group is a lens group with a positive focal power. The fourth lens group is a lens group with a positive focal power or a negative focal power, and the fifth lens group is a lens group with a positive focal power or a negative focal power.

The technology of this application relates to an actuating device, a camera module, and an electronic device. In the actuating device, an actuator is configured to include an actuating magnetic component, a power supply apparatus, and at least one coil. The power supply apparatus is electrically connected to the coil, and the coil is disposed in a magnetic field of the actuating magnetic component. When a current is supplied to the coil, the coil or the actuating magnetic component moves under an action of the magnetic field. In this case, the coil or the actuating magnetic component can drive a motor carrier to move, to drive a lens of the camera module to move, so that zooming of the camera module is completed.
