Solution Overview

Problem

Existing methods for transforming non-interlace stereoscopic images into interlace format fail to correctly align aspect ratios between the image and display panel, resulting in discomfort for viewers due to incomplete stereoscopic vision.

Innovation Solution

A method that interlaces left-eye and right-eye image data based on the specific aspect ratios of the stereoscopic image and the display panel, allowing for transformation of non-interlace formats into interlace formats while maintaining correct aspect ratios, thereby forming a completely interlaced stereoscopic image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the format of a non-interlace stereoscopic image is transformed into an interlace format without considering aspect ratio matching, then the image can be displayed on interlaced panels, but the aspect ratio will be incorrect resulting in viewer discomfort and incomplete stereoscopic vision

Engineering Contradiction:

Improvecompatibility with interlaced panelVSAvoidaspect ratio accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by adjusting the transformation process based on the detected aspect ratio of the stereoscopic image. Different transformation methods are selected depending on whether the image aspect ratio matches the panel aspect ratio, ensuring both interlaced format compatibility and correct aspect ratio display.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback by detecting the aspect ratio of the received stereoscopic image and using this information to determine the appropriate transformation method. This feedback mechanism ensures that the correct transformation is applied to maintain proper aspect ratio while achieving interlaced format compatibility.

Inventive Principle:

Principle #23Feedback

2Device complexity

If the left-eye and right-eye image data are simply interlaced without aspect ratio consideration, then the transformation process is simple, but the viewer experiences discomfort and cannot see the complete stereoscopic image

Engineering Contradiction:

Improvetransformation process complexityVSAvoidstereoscopic vision quality

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent changes the transformation parameters based on aspect ratio detection. When the image aspect ratio differs from the panel aspect ratio, the system applies specific transformation methods (such as extending or cropping) to ensure correct aspect ratio while maintaining interlaced format, thereby ensuring reliable stereoscopic vision without excessive complexity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces dynamic transformation by adapting the processing method based on the detected aspect ratio. The system dynamically selects between different transformation approaches (direct interlacing, extension, or cropping) depending on the image characteristics, optimizing both simplicity and stereoscopic vision quality.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the aspect ratio of the stereoscopic image does not match the panel aspect ratio, then format transformation is required, but incorrect transformation results in loss of stereoscopic image quality

Engineering Contradiction:

Improveformat transformation capabilityVSAvoidimage format accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent uses feedback from aspect ratio detection to guide the transformation process. By detecting the actual aspect ratio of the stereoscopic image and comparing it with the panel aspect ratio, the system selects the appropriate transformation method to achieve accurate format conversion while preserving image quality and stereoscopic characteristics.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies local quality by treating different regions of the image differently during transformation. When aspect ratio mismatch is detected, the system applies specific processing to different parts of the image (extension in certain regions, cropping in others) to maintain correct aspect ratio and stereoscopic quality throughout the transformed image.

Inventive Principle:

Principle #3Local quality

AI summary

In a display system, the invention provides a stereoscopic image format transformation method being used for transforming a non-interlace format of a stereoscopic image into an interlace format. When an aspect ratio of the stereoscopic image is not equal to an aspect ratio of a panel, the stereoscopic image format transformation method of the invention is used for interlacing a left-eye image data and a right-eye image data of the stereoscopic image according to a format of the stereoscopic image, the aspect ratio of the panel, and the aspect ratio of the stereoscopic image, to form a completely interlaced stereoscopic image.
