PROBLEM TO BE SOLVED: To obtain a stereoscopic endoscope easily small-sized and low in cost by alternately supplying power to a pair of light sources for lighting capable of separately lighting an object to be imaged by a video-camera from oblique both sides. SOLUTION: Power is alternately supplied to a pair of the light sources LG1 and LG2 by a power circuit PS, switches SW1 and SW2 and a control circuit CTL. Then it is repeated that the object OB is sometimes lighted from the oblique right side facing the object OB by the light source for lighting LG1 and on another occasion, the object OB is lighted from the oblique left side facing the object OB by the light source LG1 for lighting. An imaging signal from the camera CM is supplied to a signal processor SP through a cable LC to be signal-processed to obtain a color picture signal and the color picture signal is supplied to a monitor image receptor MR to picture the stereoscopic image of the object OB. Thus the endoscope uses only one camera to be easily small-sized. |
