Display Apparatus Eye Tracking Detail Enlargement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies fail to interactively adjust images based on viewer movements, leading to unclear details even when the viewer moves forward or tilts their body, as they lack functionality to enlarge desired details.
Innovation Solution
An apparatus comprising a video signal input, position measuring means, and image processing means that adjusts displayed images by collecting position information before and after viewer movement, using an eye tracker to detect focused areas, and enlarging or adjusting field depth to enhance clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the viewer moves forward or tilts body forward to view details, then the viewer can see objects more clearly, but the viewer cannot see small details clearly when the definition is too low
Solution Approach 1:
The display system dynamically adjusts the image by detecting viewer position changes and automatically enlarging the displayed content in real-time, transforming a static display into a dynamic interactive system that adapts to viewer movements
Solution Approach 2:
The system uses position measuring means to detect viewer position and feeds this information back to the image processing means, which then adjusts the display accordingly, creating a closed-loop feedback system that enables automatic image enlargement based on viewer behavior
2Adaptability or versatility
If no interaction function is provided for enlarging details, then the display system remains simple, but the ambience of the viewer becomes weak
Solution Approach 1:
The display system performs automatic image enlargement without requiring manual user input, using position measuring means to detect viewer movements and automatically adjusting the display, making the system self-serve the viewer's needs
Solution Approach 2:
The patent replaces manual mechanical interaction (viewer physically moving closer) with an automated electronic system that detects position and automatically enlarges images, substituting mechanical viewer action with electronic automation
3Measurement precision
If the definition of the displayed picture is increased, then small details can be viewed clearly, but the image size becomes larger requiring more space
Solution Approach 1:
The system applies local quality enhancement by enlarging only the specific region of interest that the viewer is focusing on, rather than enlarging the entire image, thus maintaining high detail clarity in the focused area while keeping the overall display area efficient

AI summary
Embodiments of the present disclosure provide an apparatus for adjusting displayed picture, comprising a video signal input means, a position measuring means, an image processing means and a video signal output means. Embodiments of the present disclosure further provide a display apparatus comprising the above apparatus for adjusting the displayed picture and a display method thereof. In the embodiments of the present disclosure, a position being concerned by viewer's eyes on the display screen is enlarged or a field depth of the position being concerned by the eyes on the display screen is increased when the viewer moves forward or tilts his/her body forward, such that the viewer can view the displayed picture more clearly, thus achieving an interaction between the displayed picture and the viewer.
