Ophthalmic Image Partitioning for Full-Scale Multi-View Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems for ophthalmic devices display multiple images of a subject eye either one at a time, making detailed examination easy but comparison difficult, or simultaneously, making detailed examination challenging.
Innovation Solution
An image processing device that synthesizes and partitions multiple images of a subject eye into regions using boundary lines, allowing for simultaneous display without reducing image scale, enabling easy comparison and examination of details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple images are displayed one at a time, then image scale is large and details can be examined easily, but comparison of multiple images becomes difficult
Solution Approach 1:
The display screen is segmented into multiple regions, with each region displaying a different image. This allows multiple images to be shown simultaneously at full scale, enabling both detailed examination and comparison without requiring users to switch between images sequentially.
Solution Approach 2:
The solution transitions from temporal display (one image at a time in sequence) to spatial display (multiple images simultaneously in different regions). This dimensional change from time-based to space-based organization resolves the contradiction by allowing both detailed viewing and comparison to occur at the same time.
2Ease of operation
If multiple images are displayed simultaneously, then image comparison becomes easy, but image scale decreases and details cannot be examined easily
Solution Approach 1:
The display area is divided into separate regions, each dedicated to displaying one image at its original scale. This segmentation ensures that each image maintains sufficient size for detail examination while still allowing multiple images to be visible simultaneously for comparison purposes.
3Productivity
If image scale is reduced to fit multiple images on screen, then simultaneous display is achieved, but image quality and detail visibility deteriorate
Solution Approach 1:
By segmenting the display into multiple regions and assigning one image to each region, the system maintains the original scale and quality of each image while achieving efficient simultaneous display of multiple images on the screen.

AI summary
An image processing device may include a first image input unit to which a first photographed image obtained by photographing a specific part of the subject eye is inputted, a second image input unit to which a second photographed image obtained by photographing the specific part is inputted, and display unit configured to display a synthesized image obtained by synthesizing the first and second photographed image. The synthesized image may be partitioned into at least a first region and a second region by a first boundary line. The display unit may be configured to display, in the first region, at least a portion which is a part of the first photographed image and corresponds to the first region. The display unit may be configured to display, in the second region, at least a portion, which is a part of the second photographed image and corresponds to the second region.
