Abstract
An optical image transmitted by an image transmitting member of a fiber scope is photoelectrically converted by an imaging device, is passed through a signal processing circuit and is displayed in a predetermined displaying position on a displaying picture surface. The range of the image imaged by the imaging device from the output signal from an imaging unit fitted with an image guide transmitting member on the exit end surface and containing the imaging device is detected, the value of the center position of the range is determined and the displaying position is corrected in response to the value.
