A ring flash light diffusion device includes a first converter ring configured to connect to a camera lens and a diffuser adapter. The diffuser adapter can be connected to a first end of the first converter ring. It also includes a flash ring connected to the diffuser adapter at a position along the length of the diffuser adapter and a ring flash connected to the flash ring. It further includes a light diffuser connected to the diffuser adapter such that light emitted from the ring flash passes through the light diffuser.

An accessory attachable to and detachable from an image pickup apparatus includes a second mount portion including a plurality of second bayonet claw portions capable of engaging with a plurality of first bayonet claw portions, a plurality of second terminals capable of contacting with a plurality of first terminals, an accessory body, and a mount fixing member for fixing the second mount portion to the accessory body. The plurality of second terminals is provided at positions different from positions of the plurality of second bayonet claw portions, and all of multiple second terminals, among the plurality of second terminals, used in communication between the image pickup apparatus and the accessory are provided at predetermined positions.

A mounting device includes an internal member and an external member. The internal member includes first magnets disposed in an inner face of the internal member, a shock cavity formed in the inner face of the internal member, and an insert disposed in the shock cavity. The external member is removably coupled to the internal member. The external member includes second magnets disposed in an inner face of the external member. The second magnets are rotatable between a locking position and a release position. The external member also includes a shock ridge formed in the inner face of the external member. The shock ridge is received into the shock cavity and compresses the insert such that impact is dampened during coupling of the internal member to the external member.

A coupling system for peripheral devices may include a housing and a shaft assembly. An end of the shaft assembly is threaded and couples to and uncouples from a peripheral device by relative rotational movement between the peripheral device and the shaft assembly. An inner cavity of the housing and another end of the shaft assembly defines a limited range of rotational motion between first and second rotational positions. Rotating the shaft assembly to the first rotational position allows for the peripheral device to be rotated relative to both the shaft assembly and the housing to couple the peripheral device to the housing via the shaft assembly. With the peripheral device coupled to the shaft assembly, relative rotational motion between the peripheral device and the housing is allowed between the first rotational position and the second rotational position without rotating the peripheral device relative to the shaft assembly.

Disclosed in an embodiment is a camera module comprising: a housing; a lens module coupled to the housing; a holder disposed in the housing; an elastic member connecting the housing and the holder; a magnet part and an optical member that are coupled to the holder; and a coil part facing the magnet part, wherein the holder includes a first protrusion that extends in an optical axis direction so as to be coupled to the elastic member, and the elastic member includes a first coupling portion coupled to one surface of the first protrusion; the first protrusion includes a guide protrusion which protrudes from the one surface of the first protrusion in the optical axis direction, wherein the guide protrusion is disposed outside the elastic member and has a shape corresponding to at least a portion of the outer circumference of the first coupling portion.

A panoramic device includes a base member and a clamp member rotatably interconnected within a single plane of rotation with the base that includes a first rotatable knob to selectively inhibit the rotation of the clamp member with respect to the base. The upper surface includes a central region that is at a different elevation than another portion of the upper surface. The clamp includes a pair of opposed surfaces suitable to detachably secure a camera thereto. The one of the opposed surfaces is maintained in a fixed relationship with respect to the clamp member. The other one of the opposed surfaces is in a movable relationship with respect to the clamp member using a second rotatable knob. The first knob and the second knob are rotatably connected with respect to one another.

An electronic apparatus to which an accessory is to be detachably attached includes a plurality of contacts electrically connectable to the accessory and arranged in a first direction orthogonal to an attachment direction of the accessory. The plurality of contacts include first reference potential contacts that are contacts disposed at both ends of the plurality of contacts and are connected to a reference potential, and second reference potential contacts that are connected to the reference potential and are contacts disposed at both ends of part of the plurality of contacts other than the first reference potential contacts in a case where the accessory is connected to the part of the plurality of contacts.

An electronic apparatus to which an accessory is to be detachably attached includes a plurality of contacts electrically connectable to the accessory and arranged in a row. The contacts include a plurality of functional signal contacts to which signals having functions that are different functions according to a type of the accessory are connected, reference potential contacts, to each of which a reference potential is connected, and contacts that are used to supply power to the accessory or to communicate with the accessory. The functional signal contacts include a first functional signal contact and a second functional signal contact. A distance from the first functional signal contact to a reference potential contact closest to the first functional signal contact and a distance from the second functional signal contact to a reference potential contact closest to the second functional signal contact are different from each other.

A method and device are provided for positioning a mounted camera. The device includes a holding element that secures the mounted camera to the device, a wireless linkage at which remote attitude commands representing attitude changes of a remote driver are received, a local controller that interprets the remote attitude commands and generates local attitude commands that move the camera to mimic an orientation of the remote driver, and an attitude sensing element that senses a local attitude of the device. The attitude sensing element includes a gyro, an accelerometer, or a magnetometer, and jitter present in the remote attitude commands is removed and not passed on to the local attitude commands.

An electronic apparatus that is capable of reducing occurrence of malfunction when an accessory is attached without enlarging an accessory shoe device. The electronic apparatus includes an accessory shoe device and a controller. The accessory shoe device is electrically connectable with an accessory and has terminals that are arranged in a line in a first direction that intersects perpendicularly with an attaching direction of the accessory. The controller is electrically connected to the terminals. At least one of the terminals differs from the other terminals in a length of an externally exposed part in a second direction that intersects perpendicularly with both the attaching direction and the first direction.
