An optical tomographic imaging method according to one aspect of the present invention is a method of: splitting light emitted from a wavelength sweep light source into measuring light and reference light； radiating the measuring light onto a measuring subject； combining reflection light from the measuring subject with the reference light； detecting interfered light obtained by combining the reflection light with the reference light as an interference signal； and Fourier-transforming the interference signal to acquire a tomographic image of the measuring subject, and includes steps of: generating tomographic data of the measuring subject based on the interference signal； generating surface data of the measuring subject based on the interference signal； constructing a tomographic image that is based on the generated tomographic data； constructing a surface image that is based on the outputted surface data； and generating a display image from the tomographic image and the surface image.
