A camera includes a lens-camera communication controller and an adapter-camera communication controller. The camera-lens communication channel includes a first data communication channel used during a data communication and a first notification channel used for a notification of a timing of a communication via the first data communication channel. The camera-adapter communication channel includes a second data communication channel used during the data communication and a second notification channel used for a notification of a timing of a communication via the second data communication channel.

An interchangeable lens assembly includes a plurality of lens-side claw portions configured to be engaged with a plurality of camera-side claw portions, and a lock pin groove portion into which a lock pin is inserted, a lens barrel, and a lens mount fixing member. When θ1 is an angle formed by a line passing through a fifth lens-side end and an optical axis, and a line passing through a center of the lock pin groove portion and the optical axis, and θ2 is an angle formed by a line passing through a fourth lens-side end and the optical axis, and a line that passes through the center of the lock pin groove portion and the optical axis, θ1 and θ2 satisfy a predetermined conditional expression.

An iris scanning device includes a first camera that captures an image of a face of a user and a second camera that captures an image of an eye of the user subsequent to the image of the face being captured. The iris scanning device includes a gimbal having a mirror mounted thereon and a facial feature detector that identifies facial features of the user based upon the image of the face. The iris scanning device further includes control circuitry that adjusts an orientation of the gimbal based upon the facial features, where the image of the eye is captured upon the orientation of the gimbal being adjusted, and where the mirror mounted on the gimbal is oriented to cause the image of the eye to be captured. An iris of the eye of the user may be located in a central region of the image of the eye.

An image capture device is described that includes a body; a mounting structure that is connected to the body; an integrated sensor-lens assembly (ISLA) that defines an optical axis and extends through the body and the mounting structure; and an accessory that is releasably connectable to the mounting structure via rotation through a range of motion less than approximately 90 degrees. The mounting structure and the accessory include corresponding angled bearing surfaces that are configured for engagement such that rotation of the accessory relative to the mounting structure creates a bearing effect that displaces the accessory along the optical axis to thereby reduce any axial force required during connection and disconnection of the accessory.

This disclosure relates to a handheld camera mount and reflector system. The reflector system includes a collapsible rod member having a collapsible reflector attached at one end of the rod. A handle is connected at the other end of the rod. A camera mount is attached to the rod between the reflector and the handle. The surface of the reflector can be adapted to adjust reflectivity, diffusion and color spectrum.

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 image capturing apparatus on which an accessory including a first mount is mountable includes a second mount. The second mount is configured to allow bayonet coupling to the first mount of the accessory. The second mount includes a plurality of terminals disposed in a circumferential direction, and a terminal holder configured to hold the plurality of terminals. Each of the plurality of terminals is electrically connectable to a terminal of the accessory. The terminal holder has a height level difference in a center-axis direction of the second mount. The plurality of terminals include a first terminal configured to be used to detect mounting of the accessory on the image capturing apparatus. The first terminal is disposed further in a mount direction of the accessory than the other terminals among the plurality of terminals on a first stage of the terminal holder.

The present invention generally pertains to a motion sensing camera for monitoring and photographing wildlife and more specifically pertains to such a wildlife camera with optical zoom capability that allows one to photograph game animals from a greater distance, reducing the likelihood of alarming game animals being photographed/filmed. The wildlife surveillance camera also optionally comprises EMF and/or RF shielding material that substantially reduces the electromagnetic field generated by said camera.

Provided is an attachment system for coupling a mobile computing device to an optic device. The optic device may be, but is not limited to a scope, binoculars or the like. The attachment system operates with attachment devices and mounting device with apertures that provide a means to couple a mobile computing device to the optic device in such a way that the attachment system provides a line-of-sight between a camera of the mobile computing device with the lens of the optic device. This allows the camera of the mobile computing device to capture images and video using the high power zoom functionality of the optic device and the convenience of the mobile computing device.

An apparatus includes multiple optical elements arranged along an optical path between an entrance aperture and an exit aperture, configured to image an object at infinity to an image at infinity and defining an exit pupil for light at the exit aperture, the image have a magnification, M, in a range from 7× to 15×. The optical elements include four non-planar mirrors. The apparatus also includes a connector configured to attach the apparatus to a mobile device having a camera with the exit pupil of the plurality of optical elements aligned with an entrance pupil of the camera of the mobile device.
