Display Device UI Element Positioning for 3D Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in maintaining high operability of UI elements when they are superimposed on stereoscopic videos, leading to difficulties in user interaction.
Innovation Solution
A display device that includes image display sections for left and right eyes, a 3D-image-data storing section, and a control section to expand and position UI element data in a way that maintains the original shape and relative position across both eyes, improving operability by ensuring the UI element is visible and easily navigable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UI element is superimposed on the stereoscopic video using conventional expansion methods, then the 3D image can be displayed, but the UI element becomes distorted and hard to operate
Solution Approach 1:
The patent applies preliminary action by performing the UI element drawing operation before the image expansion process. The control section draws the UI element on the compressed 3D image data at predetermined positions before expanding the image data in the lateral direction. This ensures that when the image is expanded, the UI element maintains its original shape and proportions, avoiding distortion that would make it difficult to operate.
2Shape
If the UI element is drawn after image expansion, then the image quality is maintained, but the UI element position and shape become inconsistent across left and right eye images
Solution Approach 1:
The patent performs the UI element drawing operation before the image expansion process. By drawing the UI element on the compressed 3D image data at predetermined positions before expansion, the control section ensures that the UI element appears at consistent relative positions in both left and right eye images after expansion, maintaining both shape consistency and positioning precision.
Solution Approach 2:
The patent applies local quality by treating the UI element drawing process differently from the main image processing. The control section draws the UI element at specific predetermined positions on the compressed image data before expansion, ensuring that the UI element maintains its original shape and consistent positioning across both eye images, while the rest of the image undergoes normal expansion processing.
3Area of stationary object
If the UI element is compressed to fit the 3D image, then the display area is optimized, but the UI element becomes difficult to operate
Solution Approach 1:
The patent performs the UI element drawing operation before the image expansion process. By drawing the UI element on the compressed 3D image data at predetermined positions before expansion, the control section ensures that the UI element maintains its original shape and size after expansion, making it easy to operate while still fitting within the optimized display area of the 3D image.

AI summary
A display device includes an image display section for left eye, an image display section for right eye, and a control section configured to expand the image data for the eyes, and cause the image display section for the eyes to display the expanded image data for the eyes. The control section acquires compressed UI image data, draws the compressed UI image data in a predetermined position of one of the image data for left eye before the expansion and the image data for right eye before the expansion, draws the compressed UI image data in a position corresponding to the predetermined position of the other of the image data for left eye before the expansion and the image data for right eye before the expansion, and performs the expansion using the image data for left eye and for right eye after the drawing.
