A camera can perform two different photographing operations with a lens at different positions without vignetting while preventing entry of light and dust. A camera includes a frame including a film compartment to contain a photographic film and a barrel extending from the film compartment in an optical axis direction, and a lens barrel movable in the barrel in X-direction. The lens barrel includes cylinders movable frontward relative to the barrel, and a cylinder movable frontward relative to the cylinder. The camera includes a rear bellows connecting the frame and the cylinder, and a front bellows connecting the cylinder and the cylinder. In a first photographing state in which the cylinders extend frontward relative to the barrel and the cylinder is accommodated inside the cylinder, the rear bellows is expanded and the front bellows is partially contracted. In a second photographing state, the cylinder extends frontward relative to the cylinder.

A camera prevents a lens barrel from extending accidentally upon receiving, for example, an external impact. A camera includes a barrel having a guide groove extending in X-direction, a lens barrel including an engagement protrusion protruding radially outward and engaged with the guide groove on the barrel, a switch spring extending between a spring engagement portion and the engagement protrusion, a drive lever rotatable about a lever shaft, a stopper rotatable about a stopper shaft in the drive lever, and a stopper urging spring urging the stopper. The drive lever includes a pusher that pushes the engagement protrusion in the positive X-direction and a rotation restrictor that restricts rotation of the stopper. The stopper includes a restraint portion that is to be on a path of the engagement protrusion to restrain movement of the engagement protrusion in the positive X-direction when the drive lever is at an initial position.

A mobile terminal includes a first body including a first surface; a second body including a second surface; a third body including a third surface; and a flexible screen coupled to the first surface of the first body, the second face of the second body and the third surface of the third body and including a first end and a second end, wherein the first end of the flexible screen is movable relative to the second surface of the second body, and the second end of the flexible screen is movable relative to the third surface of the third body.

An electronic device comprises a camera and a retaining member. The camera includes an objective portion configured to collect light from a subject, a sensor portion reversibly separable from the objective portion, and a computer configured to return an indication of alignment of the objective and sensor portions based on output of one or more optical sensor elements of the sensor portion. The retaining member is configured to couple the objective portion to the sensor portion when the objective and sensor portions are aligned and also when the objective portion is separated from the sensor portion.

An electronic device comprises a camera and a retaining member. The camera includes an objective portion configured to collect light from a subject, a sensor portion reversibly separable from the objective portion, an alignment-sensing system configured to sense a state of alignment between the objective portion and the sensor portion, an actuator configured to move the objective or sensor portion, and a computer configured to control the actuator responsive to output of the alignment-sensing system, so as to bring the objective and sensor portions into alignment. The retaining member is configured to couple the objective portion to the sensor portion when the objective and sensor portions are aligned and when the objective portion is separated from the sensor portion.

Optics systems presented are arranged as high-performance imagers particularly characterized by their exceptional compactness in view of image quality. A plurality of lens and let's and or doublets are configured to cooperate with related mount systems optimized for compactness. To achieve very high resolution imaging despite somewhat abbreviated compound lens design, these systems include use of lens array elements proximate to an imaging plane. So placed lens array devices may be designed with lens elements which invariably operate on incident wave planes with radial dependence. That is, the focusing strength of lenses from which these lens arrays are comprised may depend upon its distance from system optic axis. This enables an imaging correction function that counters distortion and other undesirable imaging errors typically present in a simplified compound lens systems. When used together and in conjunction with special-purpose collapsing lens mounting systems, an imaging system of very high fidelity and very compact weight size is achieved to great advantage in system when a premium on lens size is necessitated.

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 electronic device includes a housing, a display screen and a camera module. The display screen is combined with the housing and capable of being drawn into or out of the housing. The camera module includes a reflective element, a first lens component, a second component and an image sensor. The image sensor is configured to image based on light reflected by the reflective element to travel through the first lens component when the camera module is working in a first mode. The image sensor is configured to image based on light reflected by the reflective element to travel through the first lens component and the second lens component when the camera module is working in a second mode.

A remote control for cameras, having a grab handle unit that may be received in a first hand by a user along a handle axis and a first operating element operable using a second hand of the user and rotatable about a first axis of rotation, wherein the first axis of rotation is substantially perpendicular to a principal axis of the remote control and spans a principal plane with the principal axis, wherein the handle axis is rotated out of the principal axis within the principal plane, whereby an angle between handle axis and the first axis of rotation is higher than 90 angular degrees, wherein the remote control has an operating body with additional display means and/or operational elements within the area that is present due to the rotation of the handle axis thereout.

An optical apparatus capable of detecting an origin or the like even in a retracted state is provided. The optical apparatus includes a holding frame holding an optical system, an intermediate member, a driving unit moving the intermediate member in a direction along an optical axis of the optical system, a biasing member biasing the holding frame in a direction along the optical axis with respect to the intermediate member, and a detection unit detecting the intermediate member, and the optical apparatus also includes a first state in which a part of the holding frame is brought into contact with a part of the intermediate member according to a biasing force of the biasing member, and a second state in which the holding frame is separated from the intermediate member against the biasing force of the biasing member, in which the driving unit is able to move the intermediate member in a direction along the optical axis in either the first state or the second state, and the detection unit can detect the intermediate member at least in the second state.
