1. A biological image presentation device comprising: an acquisition unit acquiring, at multiple positions on an axis as a standard of a biological region, images of sections orthogonal to the axis; a determination unit determining an image as a standard and an image for comparison with the image as a standard from among a plurality of images acquired by the acquisition unit; an extraction unit extracting, from the image as a standard, a position where a change of luminance value equal to or larger than a defined value is present; a detection unit detecting a position corresponding to the position extracted by the extraction unit from the image for comparison; a division unit dividing the image as a standard on the basis of the position extracted by the extraction unit; a mapping unit mapping the image for comparison to an area corresponding to each divided area of the image as a standard while modifying so as to conform to the shape of the divided area; and a display control unit switching and displaying an image for display in a display area by using the image as a standard and an image mapped by the mapping unit.
