A confocal image generation apparatus includes a laser, an objective, an optical path branch element which branches an optical path of an excitation light and an optical path of fluorescence, a scanning optics which shifts alight collecting position of the excitation light on a focal plane of the objective in an orthogonal direction to an optical axis of the objective, an optical detector in which a plurality of light-receiving elements are two-dimensionally arrayed with a shorter pitch than a diameter of a fluorescence Airy disk formed on an imaging plane that is optically conjugated with the focal plane, and an image operation unit which generates a confocal image of the sample in which a super-resolution component is emphasized on the basis of a signal that is output from the plurality of light-receiving elements, the super-resolution component being a frequency component that exceeds a cut-off frequency of the objective.
