Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional 2D to 3D conversion methods apply full screen conversion, which can be distracting and degrade visual quality by converting all image data into 3D, including text and toolbar elements, leading to a nuisance for viewers trying to read or navigate 2D content.

Innovation Solution

A device and method for partial 2D to 3D conversion, using a data receiver, user interface, depth map generator, and image converter to selectively convert only a predetermined window of a 2D image into 3D, while maintaining the rest of the image in a 2D format, based on depth data and position information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If full screen conversion is applied to convert all 2D image data into 3D, then the 3D visual effect is improved, but the readability of text and usability of interface elements deteriorate

Engineering Contradiction:

Improve3D visual effectVSAvoidreadability and interface usability

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The display area is segmented into multiple regions: a first region for 3D content and a second region for 2D content (text, icons, tooltips). This segmentation allows different portions of the interface to be rendered in appropriate dimensions, improving both 3D visual effect and text readability simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different quality characteristics are applied to different regions: the first region receives 3D rendering for immersive visual content, while the second region maintains 2D rendering for text and interface elements requiring clarity. This local differentiation optimizes each region's function

Inventive Principle:

Principle #3Local quality

2Ease of manufacture

If all 2D image data is converted into 3D data, then the stereoscopic effect is enhanced, but the visual comfort and readability are reduced

Engineering Contradiction:

Improvestereoscopic effectVSAvoidvisual discomfort and readability degradation

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Text and interface elements are extracted from the 3D conversion process and maintained in 2D format. The system identifies textual content and interface elements, excludes them from 3D rendering, and displays them separately in a 2D region, eliminating the harmful effect of 3D distortion on readability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of applying 3D conversion to the entire image (excessive action), the system applies 3D conversion only to the first region containing visual content (partial action), while leaving the second region in 2D format, achieving optimal balance between stereoscopic effect and readability

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A device and method are provided for two dimension (2D) to three dimension (3D) conversion. A 2D to 3D conversion device receives a 2D image data. The 2D to 3D conversion device assigns position data of a predetermined window. The 2D to 3D conversion device generates a depth map including a depth data of the 2D image data according to the 2D image data and the position data of the predetermined window. The 2D to 3D conversion device converts the 2D image data into a 3D image data according to the depth data of the depth map and the position data of the predetermined window.
