In a first communication mode, a control unit controls a signal level of one contact based on a first command received from an imaging apparatus via another contact and a signal level indicated by an accessory device via yet another contact. In a second communication mode, the control unit receives a second command indicating the second communication mode and data via another contact. After the reception, the control unit transmits the data via still another contact. The control unit controls communication in the second communication mode based on the signal level of the one contact and the second command.

An imaging device with a compact design allows illumination with a light source and imaging with an image sensor. An imaging device includes a front case having a front surface including a window and a lens-holder receptacle aligned with each other in a width direction (X-direction), a lens holder including a lens and attachable inside the lens-holder receptacle in the front case, a first circuit board on which an image sensor to receive light through the lens in the lens holder is mounted, and a second circuit board on which an LED to emit light through the window in the front case is mounted. The first and second circuit boards extend entirely in the width direction. The second circuit board is located frontward from the first circuit board.

A tethered imaging camera encapsulated in a shell lens element of such camera enables viewing from inside and imaging of a biological organ in/from a variety of directions. A portion of camera's optical system together with light source(s) and optical detector mutually cooperated by housing structure inside the shell are moveable/re-orientable within the shell to vary a desired view of the object space without interruption of imaging process. A tether carries electrical but not optical signals to and from the camera and controllable traction cords to move the camera, and a hand-control unit and/or electronic circuitry configured to operate the camera and power its movements. Method(s) of using optical, optoelectronic, and optoelectromechanical sub-systems of the camera.
