摘要:
An endoscope used for observing the interior of a cavity in a human body. In the endoscope according to the present invention, an image sensor is provided in the forward end of an insertion section and an object of interest is displayed on a screen of a television set in response to a video signal obtained from the image sensor. According to the present invention, image information from the image sensor is provisionally stored in a memory, and the read-out from the memory is performed by horizontal scanning in accordance with read-out information by reversing the steps in the case of the write-in. With this arrangement, an image of the object of interest, which is inverted in an optical system in the forward end of the insertion section of the endoscope, can be displayed on the screen of the television as a normal image.
