Abstract
An electron microscope includes an electron optical system that irradiates a sample with an electron beam to form an image with electrons transmitted through the sample, a camera that includes an image sensor having sensor pixels and captures frame images that are based on output values output from each of the sensor pixels by incidence of the electrons on the image sensor, and a correction coefficient calculation unit that calculates correction coefficients for correcting sensitivities of the sensor pixels. The correction coefficient calculation unit determines, from the frame images captured under a condition under which the electrons incident on the image sensor follow a Poisson process, a mode value of the output values for each of the sensor pixels, and calculates the correction coefficients based on the mode value determined for each of the sensor pixels.
