Gaze-Directed Zooming Image Display System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image display systems struggle to effectively present wide-range images exceeding human visibility without requiring special devices to detect eyeball or head movement, and they often mislead users by displaying unintended regions due to unconscious visual point changes.
Innovation Solution
An image display system comprising an image creating device, a face image pickup device, and a face front point detecting device that captures and processes face images to dynamically adjust the display resolution and region focus based on the observer's intended visual point, allowing for stable high-resolution display of specific regions without external sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wide range image is displayed with sufficient image size and resolution, then the monitoring information quality is improved, but the screen size required increases
Solution Approach 1:
The patent applies local quality by displaying different resolution levels in different regions of the screen. The region corresponding to the observer's visual point is displayed at high resolution, while other regions are displayed at lower resolution. This allows the system to maintain high monitoring information quality at the focal point while reducing the overall screen size requirement.
2Area of stationary object
If a wide range image is displayed in a small-sized display device by decreasing the image size, then the system cost and space requirement are reduced, but the required monitoring information becomes difficult to obtain
Solution Approach 1:
The patent implements dynamics by dynamically adjusting the display resolution based on the observer's visual point. The system continuously tracks where the observer is looking and dynamically enhances the resolution in that specific region. This allows a small display device to provide high-quality monitoring information on demand without requiring the entire image to be displayed at high resolution simultaneously.
3Loss of information
If the specific region is selected by operating an external changeover switch, then the desired information can be obtained, but the system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically determine which region to display at high resolution based on the observer's visual point detection. Instead of requiring manual operation of changeover switches, the system autonomously adjusts the display based on where the observer is looking, thereby reducing system complexity while maintaining information accessibility.
4Measurement precision
If a sight line detecting sensor is mounted on the observer's head to detect eyeball movement, then the visual point can be accurately detected, but the device complexity and cost increase
Solution Approach 1:
The patent uses an intermediary approach by detecting the visual point through face image analysis rather than directly mounting sensors on the observer's head. The face image pickup device captures the observer's face, and the visual point is determined by analyzing the face orientation and position relative to the display. This intermediary method achieves accurate visual point detection without the complexity of direct eyeball tracking sensors.

AI summary
An image display system includes an image display device; an image creating device which creates display image data of a display image displayed in the image display device; a face image pickup device which picks up a face image of a person to look at the display image; and a face front point detecting device which creates face image data from the face image, and detects a face front point as a point positioned in front of a face of the person on the display image on the basis of the face image data. Here, the display image data are data such that the display image has a plurality of regions. The image creating device specifies a specific region corresponding to the face front point from the plurality of the regions, and creates the display image data by increasing an amount of information provided from an image corresponding to the specific region.
