Solution Overview

Problem

Conventional 3D display devices generate incorrect images when users are in an 'image dead zone' due to duplicate 3D visions in interlaced regions, causing user inconvenience.

Innovation Solution

A display system comprising an image processing device and a 3D display device that captures and processes images to identify groups of objects within a predetermined distance, adjusting the visible range by setting these groups and adjusting the display boundaries to prevent users from entering the image dead zone, ensuring correct 3D image viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the visible range is expanded to cover more users, then more users can view 3D images, but the image dead zone expands and causes more incorrect images to be displayed

Engineering Contradiction:
Improvevisible range coverageVSAvoidimage dead zone impact
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent dynamically adjusts the visible range boundaries based on real-time user positions detected by the image processing device. Instead of using fixed boundaries, the system continuously updates the visible range to match user locations, thereby expanding coverage when users are present while minimizing the image dead zone impact by excluding areas without users from the visible range calculation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback mechanism where the image processing device detects user positions and feeds this information back to the 3D display device. The 3D display device then adjusts its visible range boundaries based on this feedback, creating a closed-loop control system that adapts the visible range to actual user locations, thus expanding coverage without proportionally expanding the harmful image dead zone

Inventive Principle:
Principle #23Feedback

2Reliability

If the visible range boundaries are adjusted to exclude image dead zones, then correct images are displayed, but users near boundaries may be excluded from viewing

Engineering Contradiction:
Improveimage correctnessVSAvoiduser accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary detection of user positions before finalizing the visible range boundaries. By detecting users in advance and using their positions to define the visible range, the system ensures that users are included within the correct visible area before image display begins, thus maintaining both image correctness and user accessibility

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the parameters defining the visible range boundaries from fixed spatial coordinates to dynamic values based on user positions. By adjusting these parameters according to detected user locations, the system optimizes the balance between excluding image dead zones (maintaining reliability) and including users within the visible range (maintaining ease of operation)

Inventive Principle:
Principle #35Parameter changes

AI summary

A display device includes an image processing device and a 3D (three-dimensional) display device. The image processing device captures and processes images of a plurality of objects to obtain positions of the plurality of objects. When a distance between at least two of the plurality of objects is smaller than a predetermined distance, the image processing device sets the at least two objects as a first group and sets an object of the plurality of objects that is closest to the first group as a first object, according to the positions of the plurality of objects. The 3D display device adjusts a visible range according to positions of the first group and the first object. A method for adjusting a visible range is also disclosed herein.
