Abstract
A sample observation apparatus includes a light source unit, an illumination optical system, an observation optical system, a light detection element, a scanning unit, a holding member, and an image processing device. A light spot is formed by the illumination optical system. The scanning unit moves the light spot and the holding member relative to each other. A pupil of the observation optical system and the light detection element are positioned at a position conjugate to a pupil position of the illumination optical system. The image processing device generates an image of a sample based on a predetermined image and a filter, and the predetermined image is an image based on a signal output from the light detection element. The filter includes a first region and a second region, and a value in the first region is greater than a value in the second region.
