Solution Overview

Problem

Existing three-dimensional display technologies require synthesizing multiple images or obtaining depth maps, which increases processing load and complexity, and do not allow for flexible adjustment of depth perception without modifying parallax barriers or lenticular lenses.

Innovation Solution

An image processing device that generates a three-dimensional image by reordering video signals to be written to pixels while skipping a predetermined number, allowing for adjustable depth perception and reduced processing load, without the need for synthesizing multiple images or obtaining depth maps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple images are synthesized or depth maps are obtained to generate three-dimensional images, then three-dimensional display capability is achieved, but processing load and device complexity increase

Engineering Contradiction:

Improvethree-dimensional display capabilityVSAvoidprocessing load

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts only the necessary information (depth information) from the original image through ordering operations, rather than synthesizing multiple complete images or obtaining full depth maps. This selective extraction reduces processing load while maintaining three-dimensional display capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of the conventional approach of synthesizing multiple images or generating depth maps first, the patent inverts the process by directly ordering pixels in the original image to create three-dimensional effects. This inversion eliminates unnecessary intermediate processing steps.

Inventive Principle:

Principle #13The other way round (Inversion)

2Adaptability or versatility

If parallax barriers or lenticular lenses are modified to adjust depth perception, then depth adjustment capability is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improvedepth adjustment capabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent enables dynamic adjustment of depth perception through software-based ordering operations on pixel data, rather than requiring physical modification of parallax barriers or lenticular lenses. This allows flexible depth adjustment without manufacturing complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent replaces mechanical adjustments to parallax barriers or lenticular lenses with computational ordering operations. This substitution eliminates the need for physical device modifications while achieving the same depth adjustment effect.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If conventional three-dimensional image generation methods are used, then three-dimensional display is achieved, but resolution and processing efficiency are compromised

Engineering Contradiction:

Improvethree-dimensional displayVSAvoidimage resolution

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent segments the image processing into fine-grained pixel-level ordering operations rather than processing entire images. This segmentation allows for precise control of depth information at the pixel level, maintaining high resolution while improving processing efficiency.

Inventive Principle:

Principle #1Segmentation
