The tomographic image capturing device of the present invention comprises a display means (18) configured to: split light from a light source (11) into measurement light and reference light and cause the measurement light and the reference light to be incident to an object (E) and a reference object (49), respectively capture tomographic images of the object (E) on the basis of interference light generated by superposition of the measurement light reflected from the object (E) and the reference light reflected from the reference object (49) and display tomographic pictures of the object generated on the basis of the captured tomographic images. The tomographic image capturing device has a first image capturing mode and a second image capturing mode. The first image capturing mode is a mode in which the measurement light is two-dimensionally scanned by raster scan to be incident to the object (E) and the tomographic images of the object (E) are captured. The second image capturing mode is a mode in which the measurement light is two-dimensionally scanned by raster scan to be incident to the object (E) and the tomographic images of the object (E) are captured. The raster scan in the second image capturing mode is thinned from the raster scan in the first image capturing mode. The display means (18) is configured to be switchable between a first display mode and a second display mode. The first display mode is a mode in which a plurality of tomographic pictures including a region of interest of the object (E) is selected from among the tomographic pictures generated on the basis of the tomographic images captured in the second image capturing mode and only the selected plurality of tomographic pictures is displayed. The second display mode is a mode in which all of the tomographic pictures generated on the basis of the tomographic images captured in the second image capturing mode are in turn displayed. The capturing of the tomographic images in the first image capturi
