3D Image Output Device Curved Horizon Background Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional image output technologies face challenges in enhancing the reality of background images while maintaining manageable processing loads and data volumes, particularly in displaying three-dimensional maps on various scales, which often require complex coordinate conversions or special models to depict features like the horizon.
Innovation Solution
A three-dimensional image output device and method that superimposes a background layer with transparent and opaque portions onto the front surface of a three-dimensional object image, allowing for pseudo-expression of backgrounds like the stratosphere without using sphere or ellipsoid models, thereby reducing data volume and processing load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sphere model or earth ellipsoid model is used to express the horizon by a curved line, then the reality of the background image is improved, but the processing load and data volume remarkably increase
Solution Approach 1:
The patent divides the background image into multiple layers (sky layer, ground layer, horizon layer) that can be independently processed and composited. This segmentation allows the curved horizon to be achieved through layer composition rather than complex spherical coordinate transformations, reducing processing load while maintaining visual realism.
Solution Approach 2:
The patent uses a two-dimensional curved line to copy or simulate the appearance of a three-dimensional curved horizon. Instead of actually modeling the Earth as a sphere or ellipsoid, it creates a visual copy of the curved horizon effect using simple 2D graphics, significantly reducing data volume and processing requirements.
2Manufacturing precision
If a sphere model or earth ellipsoid model is used to express the horizon by a curved line, then the reality of the background image is improved, but the data volume remarkably increases
Solution Approach 1:
The patent creates a two-dimensional visual copy of the curved horizon rather than storing actual three-dimensional spherical or ellipsoidal Earth models. This 2D representation achieves the same visual effect with minimal data, avoiding the large data volumes associated with 3D geographic information systems.
Solution Approach 2:
The patent uses lightweight, simple graphical elements (curved lines, layered images) to represent the horizon and background instead of heavy 3D models. These simple graphical objects can be generated and discarded easily, requiring minimal storage space and processing memory.
3Manufacturing precision
If complex coordinate conversions or special models are used to depict the horizon, then the reality of the background is improved, but the processing load increases
Solution Approach 1:
The patent replaces complex coordinate conversion operations with simple 2D graphic composition operations. Instead of performing computationally intensive spherical coordinate transformations, it composites pre-rendered 2D layers with curved horizon lines, dramatically improving processing speed for real-time display applications.
Solution Approach 2:
The patent segments the background rendering into independent layers (sky, ground, horizon) that can be processed separately and composited efficiently. This allows parallel processing and optimization of each layer independently, improving overall processing throughput while maintaining visual quality.

AI summary
A projection (projected image) is drawn by perspective projection of a three-dimensional model with a background image having improved reality. When a sightline of the perspective projection looks down from above, the projected image is drawn into an object drawing area which is a lower part of an image picture. A background layer representing the stratosphere is separately generated by two-dimensionally drawing a background image, in which the stratosphere (hatched area) is opaque, while the remaining area is transparent. The boundary between the opaque portion and the transparent portion forms a curved line that is convex upward to express a curved horizon. The background layer is superimposed in front of the projected image, not behind the projected image, thereby covering an upper edge portion of the projected image including a straight-lined upper edge, so as to provide a curved boundary realizing a curved pseudo horizon in the image picture.
