摘要

A device 1 according to an embodiment of the present invention is provided with: optical mechanisms 8, 10 for causing light from a light source 2 to be guided to and scanned along tissue of skin S; a control/calculation unit 14 which controls the driving of the optical mechanisms 8, 10, acquires tomographic images of the skin S by processing optical interference signals from an optical system, and calculates a vascular plexus on the basis of the tomographic images; and a display device 16 for displaying an image of the vascular plexus. The control/calculation unit 14 calculates autocorrelation values for coordinates of a region corresponding to the epidermis in the plurality of acquired tomographic images, calculates autocorrelation values for coordinates of a region corresponding to the dermis by excluding a combination of tomographic images corresponding to a predetermined low autocorrelation among the calculated autocorrelations, and identifies, as blood vessels or blood vessel candidates, coordinates where the autocorrelation values in the region corresponding to the dermis are in a predetermined low correlation range, to calculate the vascular plexus.
