PROBLEM TO BE SOLVED: To provide an image photographing device in which the brightness of an image photographed through respective relay lenses with respect to the same object and presented to an observer can be arranged. SOLUTION: An endoscopic device has a wide angle relay lens 23 for reforming an image by an objective optical system in a rigid endoscope 10 on an imaging surface of a CCD 25 for wide angle photographing, and a relay lens 26 for enlargement for reforming a portion of the image by the objective optical system on an imaging surface of a CCD 28 for enlargement photographing. An image signal outputted from the CCD 25 for wide angle photographing is amplified by an amplifier circuit 31 and then displays an image on a monitor 40 for wide angle observation. An image signal outputted from the CCD 28 for enlargement photographing is amplified by an amplifier circuit 35 and then displays the image on a monitor 41 for enlargement observation. In the respective amplifier circuits 31 and 35, amplification factors adjusted so that the images displayed on the both monitors 40 and 41 can have the same brightness with each other are set respectively.
