Eye-Focusing Imaging Device for Automatic Zoom Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical zoom devices, such as telescopes and magnifying glasses, are inconvenient to use as they require manual setting of zoom parameters, and users with vision issues like myopia or hyperopia face difficulties in observing details of distant or small objects, while users with healthy eyes struggle to observe global information of nearby large objects.
Innovation Solution
An imaging device and method that detects the focusing point of a user's eye, determines the gazed object, and adjusts the size of the target imaging on the fundus using a predetermined zooming rule, allowing users to observe objects at a moderate distance and size, improving observing efficiency.

Engineering Contradiction Analysis
1Ease of operation
If a traditional optical zoom device is used, then zooming capability is provided, but manual setting of zoom parameters is required which reduces ease of operation
Solution Approach 1:
The imaging device automatically detects the user's focusing point and determines the gazed object without requiring manual input. The system self-adjusts zoom parameters based on the detected focusing point position, enabling the device to serve itself rather than requiring user operation for parameter setting.
Solution Approach 2:
The system continuously monitors the user's focusing point position and uses this feedback to automatically adjust the zoom level. The detection unit provides real-time information about where the user is looking, and the processing unit uses this feedback to change the size of target imaging accordingly, creating a closed-loop control system.
2Measurement precision
If the eyes view a small object or an object far from the user, then details can be observed, but users with eye problems such as myopia or hyperopia find it more difficult to recognize details
Solution Approach 1:
The system changes the optical parameters by adjusting the size of target imaging on the fundus based on the detected focusing point. When the focusing point indicates a distant or small object, the system magnifies the image; when the object is near and large, the system reduces the image size, effectively adapting the imaging parameters to compensate for vision impairments.
Solution Approach 2:
The imaging device acts as an intermediary between the user's eye and the observed object. By detecting the focusing point and adjusting the imaging size, the device mediates the visual process to provide appropriate magnification or reduction, helping users with vision impairments see details clearly without straining their eyes.
3Loss of information
If the eyes view a large object or an object near the user, then global information can be observed, but details of the gazed object become difficult to observe
Solution Approach 1:
The system dynamically adjusts the size of target imaging based on the real-time position of the focusing point. When the user gazes at a near large object, the system reduces the image size to maintain global context; when the user focuses on a distant small object, the system magnifies the image to reveal details, creating a dynamic adaptation to viewing conditions.

AI summary
To facilitate observation of object(s), an imaging process can include or an imaging device can perform detecting a position of a focusing point of an eye of a user, determining, according to the position of the focusing point, an object gazed by the user, and changing a size of target imaging of the gazed object on the fundus of the user according to a predetermined zooming rule. The size of the target imaging of the gazed object on the fundus of the user can be automatically changed by optical zooming processing, so that the user can observe the gazed object at a modest distance and with a moderate size of the imaging on the fundus, and therefore it may be convenient for the user to observe the gazed object.
