Techniques provided for using hardware and software to modify a mobile device to improve the safety and awareness of a user to their environmental surroundings. One embodiment of the invention is to update mobile device applications to include live video using the built in rear camera of area ahead of the user as background image. Rear camera would normally be viewing ground, so an embodiment includes a custom case or other attachment to the mobile device with a mirror to allow rear camera to view area ahead. The case or attachment positions the mirror relative to the camera and has an adjustable angle to achieve the correct field of view for the way (or posture) the user is holding the mobile device.

A sighting device, including an optical element having a concave reflection surface and an aiming light source and forming in a visual field frame, comprises a main-body housing section that houses the optical element and the aiming light source and has an opening on an upper surface side, a cover member that covers the upper surface side of the main-body housing section, and a link mechanism that couples the main-body housing section and the cover member and moves the cover member with respect to the main-body housing section. The cover member is moved by the link mechanism between a closed position where the cover member covers the opening of the main-body housing section and an open position where the cover member is disposed in a position separated from the opening of the main-body housing section and forms an optical path of the aiming light.

An imaging apparatus according to the present invention includes a lens unit including an image sensor, and configured to be rotatable about a tilt rotation axis, a rotating unit configured to be rotatable about a pan rotation axis, a non-rotating unit to which the rotating unit is rotatably attached, and a flexible printed circuit configured to connect the lens unit with the non-rotating unit. The flexible printed circuit includes an arc-shaped first portion coaxial with the pan rotation axis in a plane perpendicular to the pan rotation axis, and an arc-shaped second portion coaxial with the tilt rotation axis in a plane perpendicular to the tilt rotation axis. The first portion is bent around an axis orthogonal to the pan rotation axis.

In a mount device including a mount which an accessory is attachable to and detachable from, a plurality of terminals arranged along a circumferential direction of the mount and used for electrical connection with the accessory includes a first terminal which is used to supply driving electric power serving as a first voltage to the accessory, and a second terminal which exhibits a voltage that changes according to the accessory mounted to the mount device, wherein the second terminal is able to be set to an input state or an output state, and is set to the input state during a period in which the driving electric power is not output to the accessory via the first terminal.

An illumination apparatus includes: a light-guiding portion including a light-introducing opening through which light is introduced from a light-emitting portion of an image pickup apparatus, a reflective surface that reflects light introduced from the light-introducing opening toward an image pickup optical axis of the image pickup apparatus, and a diffusion portion that diffuses the light reflected by the reflective surface toward an object as diffused light; and a reflective body including an opening portion allowing an image pickup opening of the image pickup apparatus to be exposed, and a reflective portion provided around the opening portion and including a reflective surface formed to expand from the opening portion toward the object, wherein the diffusion portion is disposed at a part of the reflective portion and the reflective body includes a wall portion extending to the object side at a boundary between the opening portion and the diffusion portion.

An imaging apparatus includes a camera communicator connected to a signal communication channel and a data communication channel, and a camera controller configured to perform a signal communication with the plurality of accessory apparatuses using the signal communication channel, and a first communication that is a data communication with the plurality of accessory apparatuses and a second communication that is a data communication with a first accessory apparatus among the plurality of accessory apparatuses, using the data communication channel. The camera controller notifies a second accessory apparatus other than the first accessory apparatus of a communication prohibition by the second communication, and then notifies a change of a clock rate of at least one of the first communication and the second communication via the second communication to change the clock rate.

An image capture apparatus that makes it possible to properly update a second accessory that is attached to a first accessory attached to the image capture apparatus, and a method for controlling the image capture apparatus, are disclosed. An update target accessory, out of the attached first accessory and the second accessory attached to the first accessory, is set based on the operation status of the first accessory and the operation status of the second accessory. If it is determined that the operation status of the first accessory is abnormal, the first accessory is set as the update target accessory, regardless of the operation status of the second accessory.

Disclosed herein is a standalone audiovisual apparatus for the simultaneous acquisition and management of coverage, the simultaneous recording, and live on-the-fly editing of multiple angles, in accordance with some embodiments. Accordingly, the audiovisual apparatus comprises a body and arms. Further, the body comprises an upper body portion and a lower body portion. Further, the upper body portion comprises a body adapter disposed on the upper body portion. Further, the body adapter is configured for detachably attaching a primary recording device to the body adapter. Further, the lower body portion is disposable on a surface. Further, the arms are coupled to the body. Further, the arms comprise arm adapters. Further, the arm adapters are configured for detachably attaching secondary recording devices to the arm adapters. Further, the arms are configured for moving between arm positions in relation to the body for positioning the secondary recording devices in secondary recording positions.

The type of lens attached to the lens attaching portion is determined. In a case of the multiple-property lens being attached to the lens attaching portion, a plurality of images corresponding to the plurality of areas is generated. In a case of the typical lens being attached thereto, one image is generated from imaging signals of all pixels of the directional sensor. In the case of the multiple-property lens being attached to the lens attaching portion, performed is correction of removing, from an image generated in correspondence with one area of the plurality of areas, influence of a luminous flux passing an area other than the one area. In the case of the typical lens being attached thereto, a difference in sensitivity for each pixel of a plurality of types of pixels is corrected.

The present invention provides the following camera. A first camera-side contact pin is a pin corresponding to detection of a signal change caused by coupling of a camera accessory. A second camera-side contact pin is a pin corresponding to supply of power for communication with the coupled camera accessory. A third camera-side contact pin is a pin corresponding to supply of a driving force to an actuator of the camera accessory. The first, second, and third camera-side contact pins are disposed in such a manner that, when a camera-side mount shifts from a first state to a second state, the third camera-side contact pin contacts first and second accessory-side contact surfaces, the second camera-side contact pin contacts the first accessory-side contact surface, and the first camera-side contact pin does not contact the second and third accessory-side contact surfaces.
