PURPOSE:To realize clear photography by setting an endoscope or camera side in such a state that no Moire stripe appears in a photographed image according to the direction of an array of fibers forming an image guide and an array of a recording medium in use. CONSTITUTION:A camera 11 is mounted on the eyepiece part 4 of a soft endoscope 1 and fixed by a rotation stopper screw 16 with an index 32 at a set position mark 33. An image is observed through a viewfinder in said state and an adjusting ring 31 is rotated set a lens 19 in a clear observation state; and a shutter release button is pressed when necessary to obtain an optical image of a subject 22 on the surface of a film 20 almost without moire. The image guide 23 is extended from a tip constitution part 7 to the eyepiece part 4 through a curved part 8, an insertion part 2 behind it, and an operation part 3 to transmit the optical image to the front-side rear end surface of the eyepiece part 4, i.e. projection end surface 23B, the image on which is formed clearly on the surface of the film 20 at the image-formation position through lenses 18 and 19. |
