PROBLEM TO BE SOLVED: To provide a video microscope in which image data for one frame are repeatedly read from a memory and displayed on a display device as a still picture and light source feeding power is controlled to extinct a light source during this display period. SOLUTION: In the video microscope, an image of an observation object illuminated with illumination light generated by a light source 10 is captured via an optical magnification system 3, converted into a video signal by an imaging unit and displayed on a display device 9. The video microscope comprises: a video switching means 85 for switching a video signal to be inputted to the display device 9 between an imaging unit 4 and a D/A converting means 82; a still picture generating means 74 for giving a command to a memory control means 81 so as to repeatedly read image data for one frame from a memory 83 and controlling the video switching means 85 so as to input the video signal from the D/A converting means 82 to the display device 9; and a light source control means 11 for controlling light source feeding power so as to extinct or turn off the light source 10 while the still picture is displayed on the display device 9.
