Abstract

Tomographic images of a plurality of planes at a disease site of a fundus are taken exactly within a short period of time, and the tomographic images are respectively displayed so that the positional relationship thereof becomes clear. A low coherent optical tomographic image sensing apparatus for imaging a fundus includes a sensing unit which takes tomographic images of a plurality of planes intersecting each other in time division, a display unit which displays the taken tomographic images at separate sites on the identical screen, and a position indication unit which displays, in each tomographic image, an intersection position of the tomographic image and another tomographic image intersecting one another.

First claim

What is claimed is:

1. An apparatus for taking tomographic images of an object using optical coherence tomography, the apparatus comprising:
an instruction unit configured to instruct independently to change positions of a plurality of planes intersecting each other;
a unit configured to take tomographic images of regions of the object corresponding to the positions in time division; and
a display controlling unit configured to control a display unit to display the tomographic…
