PURPOSE: To perform remote photographing operation without reference to an installation position, etc., by using an optical transmission calbe, such as an optical fiber, for the picture plane monitoring method of a portable video camer a.

CONSTITUTION: An picture is formed on one end surface 40a of an optical fiber body 40 through an imaging lens 41, and the light travels in the optical fiber body 40 and is transmitted optically to the opposite-side end surface 40b. The picture on this end surface 40b is enlarged through a condenser lens 43 and observed. The position relation between both the end surfaces 40a and 40b is set freely, so a monitor picture is observed and shot at an optional place distant from a video camera body.
