ABSTRACT:
A TV camera of this invention is adapted to be attached to an eyepiece section of, for example, an endoscope. The camera has a camera body with an eyepiece section. A camera mount is attached to the front portion of the inside of the casing so that the camera body is mounted on the eyepiece section of the endoscope. A beam splitter is arranged behind the camera mount to allow light which has been incident into the camera body to be split into two beams of one and the other beam. An image pickup element block includes an image pickup element for receiving the light conducted in the light incident direction and an optical system for projecting the beam travelling in the beam-incident direction onto the receiving surface of the image pickup element where an image is formed. The element block is mounted on the rear side of the beam splitter such that it is detachable from the camera body. A finder optical system is disposed parallel to the image pickup block to conduct the other beam to the eyepiece section of the camera body. It is possible to exchange an initially attached image pickup element with another image pickup element of a different size by replacing only the image pickup element block without replacing the finder optical system.
