The tomographic image capturing device of the present invention includes a tomographic image capturing means that scans measurement light on a subjects eye fundus (E) to capture tomographic images of the subjects eye fundus and an image processing means that compresses a picture of the captured tomographic images in a scan direction to generate a new tomographic picture. The tomographic image capturing means performs scan at a second scan pitch (PL) narrower than a first scan pitch (PH) to capture the tomographic images of the subjects eye fundus. The image processing means compresses the picture (B11) of the tomographic images captured at the second scan pitch (PL) in the scan direction to generate the new tomographic picture (B12). The measurement width in the scan direction of the new tomographic picture (B12) is a width of a picture corresponding to a measurement width in the scan direction of a tomographic picture (Bn (n=1 to 10)) obtained by scan at the first scan pitch (PH).
