Providing an intermittent photo-taking device capable of correcting a
focus drift in the optical axis direction by moving a stage to focus on a
plurality focus position of a sample. The intermittent recording device 9
receives setting of a photo-taking timing for the intermittent recording,
sets to a driving system 2 a plurality of focus points to take
photographs of the sample in each photo-taking timing as relative
positions with respect to a predetermined reference position, at each
photo-taking timing, obtains a focus position as a reference position by
the autofocus movement, varies the relative position between the
microscope 1 and the stage 51 to focus on the set photo-taking position
of the sample S on the basis of the obtained reference position and the
relative positions, makes the photo-taking device 8 take photograph of
the sample in each focus position, and captures the taken images.
