A new tomographic image is generated using a reverse image in which at least one portion of a tomographic image of a retina of an eye to be examined is reversed and the tomographic image so that the reverse image is located on a side on which the retinal layer in the tomographic image is in contact with an end of the tomographic image.

1. Field of the Invention
The present invention relates to an image processing device, an image processing system, an image processing method, and a program, and, more particularly, relates to an image processing device, an image processing system, an image processing method, and a program that use a tomographic image of an eye portion.
2. Description of the Related Art
FIG. 1 is a diagram illustrating a configuration of an image processing system according to a first embodiment.
FIGS. 2A and 2B are flowcharts illustrating the flow of a process performed in an image processing device according to the first embodiment.
FIG. 3 illustrates an example of display, in the case of image capture, in a display screen of a display section of the image processing system according to the first embodiment.
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. Note that, in an image processing system including an image processing device according to the present embodiment, even when a tomographic image of the retinal layer that is highly curved, such as the retinal layer of a highly myopic eye, has been captured, display is performed so that the shape of the entire retinal layer can be grasped.
Here, when the retina is highly curved, such as the retina of a highly myopic eye, the retina layer is folded back in the upper portion of a tomographic image. Thus, there are cases in which image capture or analysis is not correctly performed.
For example, the case where a coherence gate position is specified on the vitreous-humor side and where a tomographic image of an eye in which the retinal layer is highly curved is captured will be described using FIG. 14. As illustrated in FIG. 14, when the retinal layer is highly curved, there is a case in which a tomographic image is captured so that the retinal layer is in contact with the upper end portion of the tomographic image. In a portion of a tomographic image on the right side thereof illustrated in FIG. 14, an image in which the portion is folded back is generated. Accordingly, in such a portion, because the retinal layer is folded back and superimposed on itself, it is difficult to easily grasp the shape of the retinal layer.
