The first mount is fastened to the adapter device by multiple screws, and has first through third mount recesses and first through third mount claws disposed following a circumferential direction. The second mount is fastened to the device by multiple screws, and has fourth through sixth mount claws and fourth through sixth mount recesses disposed following the direction. The first through third mount claws are insertable to mount recesses on an imaging apparatus, the fourth through sixth mount claws are insertable to mount recesses on an accessory, and the smallest angle range of the first through third mount recesses in the direction of the first mount is not greater than the smallest angle range of the fourth through sixth mount claws in the direction of the second mount.

Systems and processes for cameras with a reconfigurable lens assembly are described. For example, some methods include automatically detecting that an accessory lens structure has been mounted to an image capture device including a mother lens and an image sensor configured to detect light incident through the mother lens, such that an accessory lens of the accessory lens structure is positioned covering the mother lens; responsive to detecting that the accessory lens structure has been mounted, automatically identifying the accessory lens from among a set of multiple supported accessory lenses; accessing an image captured using the image sensor when the accessory lens structure is positioned covering the mother lens; determining a warp mapping based on identification of the accessory lens; applying the warp mapping to the image to obtain a warped image; and transmitting, storing, or displaying an output image based on the warped image.

A lens apparatus detachably attached to an image pickup apparatus body includes a controller configured to perform communication with the image pickup apparatus body with respect to driving of an optical member, wherein the controller is configured to transmit, based on first information for identifying the image pickup apparatus body transmitted from the image pickup apparatus body, second information for identifying the lens apparatus to the image pickup apparatus body, and transmit, based on third information for identifying the image pickup apparatus body transmitted from the image pickup apparatus body after transmission of the second information, fourth information for identifying the lens apparatus to the image pickup apparatus body.

A camera body with which it is possible to improve the effect of shake correction, a camera accessory, and an information transmission method wherein the camera body to which a camera accessory can be detachably mounted, and includes: a movable section which is movable to correct shaking of the camera body; a detection unit which detects the shake and outputs a detection signal; a calculation unit which, on the basis of the detection signal, calculates an amount of movement of the movable section; and a transmission unit which transmits, to the camera accessory, body-side information the calculation unit uses to calculate the amount of movement.

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.

Measurement apparatus (20) includes a garment (24, 26, 140, 160) including an elastic fabric (27) having a predefined pattern (28) extending across a surface thereof and configured to be worn over a part of a body of a subject (22), such that the elastic fabric stretches across the part of the body. A camera (30, 80) is configured to capture images of the pattern while contacting and traversing across the surface of the fabric while the subject wears the garment. At least one processor (32, 36, 60) is configured to process the images captured by the camera at multiple locations on the surface of the fabric so as measure a local deformation of the pattern at the multiple locations due to stretching of the fabric, and to compute a dimension of the part of the body responsively to the measured deformation.

A lens device with which a network can be pulled out from a lens main body and connected to an operation terminal is provided. The lens device for capturing an optical image includes: a lens mechanism for forming the optical image, the lens mechanism being built into a lens main body; a drive control unit for drive-controlling the lens mechanism, the drive control unit being built into the lens main body; a central processing unit that outputs a drive control signal to the drive control unit; and a network that forms a power supply interface for the lens main body, and a communication interface for the central processing unit. Thereby, the lens and the operation terminal are connected via the network, so that it is possible to expand the connection mode between the lens and the operation terminal to an n-to-one or n-to-n connection mode.

A portable remote controlled video production apparatus and method are provided, as is a teleprompter/Interrotron integrated with a camera. A computer is mounted in a rigid cage, the computer having a local portion of remote access remote control software. A camera is fixedly mounted in the cage in communication with the computer; either the camera or the computer have camera control software running thereon. A monitor is fixedly mounted in the cage in front of the camera and parallel to the lens axis; the monitor is in communication with the computer. A beamsplitter is fixedly mounted in the cage in front of the lens reflecting light from the monitor towards a front of the cage. The camera and computer are controllable remotely via a remote portion of the remote access remote control software running on a remote computer communicating with the local portion of the remote access remote control software.

An image processing apparatus determines whether an image represented by image data includes two circular areas and executes predetermined processing on the image if it is determined that the image includes two circular areas. The image processing apparatus can recognize if the image data is taken with a dual-eye lens even when an image capture apparatus that has recorded the image data has not recognized that a dual-eye lens unit has been attached and processing the image appropriately.
