PROBLEM TO BE SOLVED: To provide an electron microscope whereby a region producing over range can be intelligibly recognized, and a gain, a contrast and the like can be easily adjusted. SOLUTION: This electron microscope is provided with an over range extraction setting means to display over range regions P. Y corresponding to over ranges in gradation expression and other regions in an observed image imaged by the electron microscope, by different modes. The over range extraction setting means converts the over region P of the observed image having a larger gradation value than a first prescribed value and the under region Y of the observed image having smaller gradation value than a second prescribed value to different color tones by image processing to display them in the over range region. Thereby, an operator of the electron microscope can recognize each over range region based on a converted color. COPYRIGHT: (C)2004,JPO
