An intermittent photo-taking device for a microscope includes a condition setting means that sets an intermittent photo-taking condition composed of a given time lapse and the number of frames to be photo-taken, an image obtaining means that obtains an image taken under the intermittent photo-taking condition, a setting change means that changes the intermittent photo-taking condition in the middle of an operation based on the intermittent photo-taking condition set by the condition setting means, and a memory that, when the intermittent photo-taking condition has been changed by the setting change means, stores an image taken under the changed intermittent photo-taking condition following an image taken under the intermittent photo-taking condition before changing.
