Eye Fundus Imaging for Automatic Optical Zoom Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical zooming devices require manual setting of zooming parameters, making them inconvenient for use, especially for users with vision issues or when viewing objects at varying distances, which can lead to difficulties in observing details or panorama information.
Innovation Solution
An imaging device and method that determines the gazed object by analyzing the eye fundus image and automatically adjusts the image size using optical zoom processing based on predetermined rules, ensuring the object is viewed at an appropriate size and distance for comfortable observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual zooming devices (telescope or magnifier) are used, then image magnification can be achieved, but operation convenience deteriorates due to manual setting requirements
Solution Approach 1:
The system captures images of the eye fundus and automatically determines the gazed object without requiring manual user input. The processor analyzes the eye fundus image to identify what the user is looking at, and the system autonomously adjusts zooming parameters based on this determination, making the device serve itself rather than requiring manual operation.
Solution Approach 2:
The system uses feedback from eye fundus imaging to automatically control zooming. By continuously monitoring the eye fundus to determine the user's gaze target, the system receives feedback about what the user wants to observe and automatically adjusts the magnification level accordingly, creating a closed-loop control system that adapts to user needs in real-time.
2Area of stationary object
If viewing relatively small or far objects, then observation scope is expanded, but detail observation capability deteriorates
Solution Approach 1:
The system dynamically adjusts the zooming magnification level based on the determined gazed object and predetermined zooming rules. Rather than being fixed at a single magnification level, the system can switch between different zoom levels to optimize both the observation scope and detail capability depending on what the user is viewing, making the observation parameters adaptive rather than static.
3Measurement precision
If viewing relatively large or near objects, then detail observation capability is improved, but panorama information observation deteriorates
Solution Approach 1:
The system dynamically adjusts zooming magnification based on the size and distance of the gazed object. When a large or near object is detected, the system can automatically reduce magnification to capture more of the surrounding panorama, whereas for small or far objects, it increases magnification to reveal details, thus adaptively balancing detail observation and panorama coverage.
4Productivity
If automatic zooming based on eye fundus analysis is implemented, then observation efficiency is improved, but device complexity increases
Solution Approach 1:
The imaging device serves multiple functions: it captures the eye fundus image, processes this image to determine the gazed object, and uses this information to control the zooming operation. By making the imaging system multi-functional (both diagnostic and control functions), the patent avoids adding separate independent systems, thereby limiting the increase in overall device complexity while still achieving automatic adaptive zooming.

AI summary
An imaging method includes determining a gazed object of a user according to an image at the user's eye fundus; and changing a size of a target image of the gazed object according to a predetermined zooming rule. A device comprises: an object determination unit configured to determine a gazed object of a user according to an image at the user's eye fundus; and a processing unit configured to change a size of a target image of the gazed object according to a predetermined zooming rule. The size of the target image can be changed by optical zoom processing, so that the user feels that the gazed object is observed with an appropriate size of the image at the eye fundus at an appropriate distance, thereby facilitating the user to observe the gazed object and improving the observation efficiency.
