Superimposed En-Face and SLO Image Display for Eye Fundus Analysis
Solution Overview
Problem
Existing OCT image processing systems require examiners to move their sight line over a significant distance to compare SLO images and En-Face images, making it inefficient for analysis.
Innovation Solution
An information processing apparatus that acquires both SLO and En-Face images and displays them superimposed on a front image, allowing the depth range of the En-Face image to be adjusted, thereby reducing the distance needed to compare these images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If SLO image and En-Face image are displayed side by side, then both images can be displayed clearly, but the examiner must move the sight line over a long distance for comparison
Solution Approach 1:
The patent merges the SLO image and En-Face image into a single composite image by superimposing the En-Face image onto the front image. The display control portion overlays the En-Face image at a predetermined position on the front image, allowing both images to be viewed simultaneously at the same location, thereby eliminating the need for sight line movement between separate displays.
2Length of moving object
If En-Face image is superimposed on front image, then sight line movement distance is reduced, but the depth range of the En-Face image needs to be adjustable for optimal viewing
Solution Approach 1:
The patent implements dynamic adjustability of the depth range for the En-Face image. The display control portion is configured to change the depth range at the eye fundus of the En-Face image that is superimposed on the front image, allowing the system to adapt to different viewing requirements and anatomical variations without adding significant complexity.

AI summary
An information processing apparatus includes a first acquisition portion acquiring a front image of an eye fundus, a second acquisition portion acquiring an En-Face image on the basis of a plurality of tomographic images of the eye fundus, and a display control portion controlling a display unit to display the En-Face image in a superimposed relation to the front image. The display control portion changes a depth range, at the eye fundus, of the En-Face image superimposed on the front image.
