Claims

[Scope of utility model registration request]

(1) Television camera 1, electric circuit 2 and cathode ray tube 3
A monitor television device for monitoring a high-brightness object 6 essentially consisting of a lens system 4 that forms an image of the subject in front of the television camera, and a portion of the image corresponding to the high-brightness object. The apparatus is characterized in that it is provided with a filter 5 for blocking or attenuating strong light from the television camera.

(2) Practical use in which the image of the subject is an aerial image, and the filter 5 is a light-blocking or dimming object with a shape similar to that of the high-luminance object, placed at an arbitrary position between the aerial image and the television camera. Device according to claim 1 of patent registration.

(3) The image of the object is an image formed on a focusing plate, and the filter 5 is a light-shielding or light-reducing paint applied to a portion of the high-intensity object on the focusing plate. The device described in Section 1.
