1. A specimen observation apparatus comprising:
- an objective lens that radiates laser light emitted from a light source onto a specimen;
an image-data obtaining portion that is configured to detect return light from the specimen irradiated with the laser light by the objective lens and that obtains an image; and
a computer that is configured to;
repeatedly detect the return light from a same region on the specimen with the image-data obtaining portion and obtain a plurality of images for the same region from the repeated detection;
add the plurality of images for the same region, obtained by the image-data obtaining portion, so as to obtain added image data; and
subject the added image data, serving as a raw image, to further processing to emphasize high-frequency components in the obtained added image data to generate a superresolution image.

Abstract
A superior superresolution image can be generated. Provided is a specimen observation apparatus including an objective lens that radiates excitation laser light emitted from a light source onto a specimen; and a main controller that obtains a plurality of sets of image data of the same region on the specimen by repeatedly detecting fluorescence from the same region on the specimen irradiated with the excitation laser light by the objective lens, and that emphasizes high-frequency components in an addition image data obtained by adding the obtained plurality of sets of image data of the same region on the specimen.
