In a video system of the invention, control means is provided for a terminal input apparatus which is connected by a communication network of a camera on the partner side and which comprises an image display apparatus having a multiwindow display function for selecting and displaying the camera. An image pickup operation which is required to the camera on the partner side, for example, the image pickup direction, focal distance, panning, exposure amount, white balance, automatic focusing, and the like of the designated camera are inputted by using an image display and a window display of the image display apparatus. The operation of the camera on the partner side and the operations of a tripod, a movable arm, and the like to hold the camera are controlled through communicating means. A photographed image is displayed by the display apparatus.

Video system

An image formation apparatus comprising a rear plate on which a plurality of wires for connecting electron emission devices are placed; a faceplate arranged in parallel to the rear plate in a frame, on which an image formation material for forming images by radiation of electrons emitted from the electron emission devices is placed; spacers placed between the rear plate and the faceplate and placed on the wires of the rear plate; and getters provided on the wires on which a spacer is not placed but not provided on the wires on which the spacer is placed.

An electron beam apparatus includes an electron source having an electron-emitting device, an electrode for controlling an electron beam emitted from the electron source, a target to be irradiated with an electron beam emitted from the electron source and a spacer arranged between the electron source and the electrode. The spacer has a semiconductor film on the surface thereof that is electrically connected to the electron source and the electrode.

Electron beam apparatus and image forming apparatus

An image formation apparatus is disclosed which includes, within an enclosure configured by a pair of substrates placed face to face and an external frame placed between the substrates, an electron source placed on one of the pair of substrates, an image formation material placed on the other substrate, and spacers placed between the substrates, characterized in that the spacers and the external frame is conductive and device is provided for electrically connecting the spacers and the external frame so that the equipotential surfaces between the spacers and the external frame are quasi-parallel when driven.

Image formation apparatus having fluorescent material and black material

A spacer on which static electricity is restricted and an electron beam apparatus in which the spacer is provided. In the electron beam apparatus comprising an electron source provided with electron emission devices, a face plate provided with anodes and spacers installed between the electron source and the face plate, unevenness is formed on the surface of the spacer substrate, and further a thin film which has a smaller thickness than a roughness. This makes possible the restriction of incident angle multiplication coefficient for the primary electrons whose energy is lower than the second cross-point energy of a resistive film. The electron beam apparatus provided with the above spacer is excellent in display definition and long-term reliability since the display of light emission points and the creeping discharge accompanying the static electricity can be restricted due to the spacer.

Electron beam apparatus and spacer

An electron beam apparatus including a hermetic container provided with an electron source, in which, when a first member is arranged in the hermetic container, at least part of the first member is coated with a film, and the film is configured in such a manner that it includes two regions, a first region and a second region different in electron density from the first region and the second region forms a network in the first region. This three-dimensional network structure allows a member being charged to be preferably controlled. Thereby, it is possible to control the effects of a member being charged which is used in an electron beam apparatus.

An electron beam emitting apparatus has a first plate with an electron-emitting device, and an electrodeopposed to the first plate, and the electrodeis applied a potential to accelerate electrons emitted from the electron-emitting device. In the electron beam emitting apparatus, a potential defining regionis provided a surface of the first plate on the electrodeside and a first potential defining region forming the potential defining regionis provided in a projective area of the electrodeonto the potential defining region; and, where d represents a distance between the electrodeand the potential defining region, an additional potential defining region is defined in the range of 0.83d in all directions parallel to the first plate from the edge of the projective area of the electrodeonto the potential defining region. This stabilizes trajectories of electrons and permits an excellent image to be formed without deviation of light emission positions.
