PURPOSE:To provide an endoscope device which generates a good observation image of an object to be photographed by preventing deterioration of the image due to light other than the illumination light for observation such as visible rays. non-visible rays, and flame light. CONSTITUTION:An object to be photographed is illuminated and put out of illumination periodically, and a 1st memory 33 and a second memory 34 store the image pickup signal of the object when it is illuminated and the image pickup signal when out of illumination. The signals stored in these memories 33, 34 are subjected to a computational processing by a subtracting circuit 35, and the image pickup signal of the object due to illumination is emitted, and this output signal is processed into video signals by a video process circuit 37. |
