Image Display Device With Observation-Triggered Detail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices generate unnecessary calculation loads due to high-definition processing when the user has no interest in observation, and fail to maintain uniform display definition when the user is interested in a specific range, leading to unnaturalness.
Innovation Solution
An image display device and method that control the display processing unit to maintain low content level display initially, switching to high content level only when the user's observation point stays within a prescribed range for a set period, and revert to low content level when the user moves away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-definition processing is applied to the vicinity of the observation point, then the user can observe detailed information, but unnecessary calculation load is generated when the user has no interest in observation
Solution Approach 1:
The patent applies dynamics by making the display definition variable rather than fixed. The processing unit dynamically switches between high-definition and low-definition processing based on real-time detection of user observation behavior. When the observation point remains within a prescribed range for a prescribed period, high-definition processing is activated; otherwise, low-definition processing is used, thus adapting the system performance to actual user needs.
Solution Approach 2:
The patent changes the parameter of display definition (quality level) based on observed user behavior patterns. By monitoring whether the observation point stays within a prescribed range for a prescribed period, the system adjusts the processing quality parameter accordingly, switching between high and low content levels to optimize the balance between display quality and calculation load.
2Measurement precision
If display definition is changed according to distance from the observation point, then the observation point can be displayed with high accuracy, but the display definition becomes non-uniform and the object looks unnatural
Solution Approach 1:
The patent segments the display into different quality levels based on spatial location and user interest. Instead of uniformly applying high definition across the entire field of view, it divides the display into high-definition regions (where the observation point remains for a prescribed period) and low-definition regions (surrounding areas), creating a segmented quality distribution that maintains natural appearance.
Solution Approach 2:
The patent implements local quality by applying high-definition processing only to specific local regions where the user shows sustained interest, while maintaining low-definition processing for other areas. This localized high-quality display ensures that only the relevant portion of the image receives intensive processing, preserving natural appearance while optimizing performance.
3Reliability
If high-definition processing is applied constantly, then the user interest can be addressed at any time, but calculation load increases unnecessarily when the user has no interest
Solution Approach 1:
The patent employs periodic action by continuously monitoring user observation behavior to determine when high-definition processing should be activated. The system periodically checks whether the observation point remains within a prescribed range for a prescribed period, and only then switches to high-definition processing. This periodic evaluation ensures that high-quality processing is applied only when actually needed, reducing wasted calculation resources.

AI summary
An image display device is for displaying an image including a user in, and comprises: a display processing unit displaying an image within a user's visual field display range; and a processor controlling the entire operation including a display operation on the display processing unit. The processor controls the display processing unit such that, in a state where information is displayed at a low content level within a visual field display range by control of the display processing unit, when an observation point which a user observes closely stays within a prescribed display range for a prescribed period of time, the vicinity of the observation point is displayed as information of a high content level, whereas when the observation point has deviated from the location of said information of the high content level, the vicinity of the observation point is returned to the information display at the low content level.
