Abstract
An image processing system includes: an analysis unit configured to obtain information indicating a degree of curvature of a retina from a tomographic image of an eye to be examined; and an obtaining unit configured to obtain a category of the eye to be examined based on an analysis result.
Claims12
An image processing system comprising:
- a memory that stores a program;
- and
- a processor that executes the program stored in the memory so as to function as units including:
- an image obtaining unit configured to obtain a fundus image captured by a fundus imaging device and a plurality of tomographic images captured by a tomographic imaging apparatus;
- a detection unit configured to detect a retinal layer of a fundus retina in each of the plurality of tomographic images;
- a feature amount obtaining unit configured to obtain a feature amount of the retinal layer of the fundus retina based on the detected retinal layer of the each of the plurality of tomographic images;
- a map generation unit configured to generate a feature amount map based on the feature amount of the retinal layer;
- and
- a display control unit configured to display side by side a current image analysis result of a current plurality of tomographic images and a previous image analysis result of a previous plurality of tomographic images on a display screen, each of the current image analysis result including the current tomographic image, a current fundus image and a current feature amount map superimposed on the current fundus image and the previous image analysis result including the previous tomographic image, a previous fundus image and a previous feature amount map superimposed on the previous fundus image.
