Abstract

The present invention relates to an image generation method for an objective for generating an image corresponding to a multi-frame image from image signals obtained by scanning a small number of frames are proposed. To achieve the above objective, there is proposed a method of performing two-dimensionally scanning on an object on a sample with a beam a plurality of times, generating a first image by integrating image signals obtained by a plurality of times of scanning at a first timing among the image signals generated based on the plurality of times of the two-dimensional scanning (S), generating a second image based on the smaller number of times of scanning than the number of times of scanning at the first timing including scanning after the first timing (S), training a learning device by using teacher data with the second image as an input and the first image as an output (S), and inputting input image signals obtained by the smaller number of times of scanning than the number of times of scanning at the first timing to the trained learning device to output an estimated image.
