3D Display Border Detection for Accurate Stereoscopic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
3D displays often fail to accurately recognize the 3D image format, leading to a lack of smooth and immersive stereoscopic visual experiences.
Innovation Solution
An electronic apparatus and method that detects a specific pattern border surrounding a streaming image using line detection to determine if it conforms to a stereoscopic format, generating a stereoscopic format image and controlling the 3D display to operate in a stereoscopic mode accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 3D display attempts to provide stereoscopic visual effects, then the visual experience quality is improved, but the ability to accurately recognize 3D image format deteriorates
Solution Approach 1:
The patent applies preliminary action by embedding a specific pattern border around the streaming image before display. This border serves as a pre-prepared marker that enables the 3D display to automatically detect and recognize stereoscopic content format in advance, rather than attempting to recognize after display issues occur. The border is inserted into the video stream during encoding, allowing the display device to proactively identify and switch to appropriate 3D display mode.
2Measurement precision
If line detection is performed to detect the specific pattern border, then the detection accuracy of stereoscopic content is improved, but the processing time increases
Solution Approach 1:
The patent applies color changes by using a specific pattern border with distinct visual characteristics that can be easily differentiated from normal video content. The border employs specific color patterns or contrast differences that simplify the line detection algorithm's work, allowing rapid identification of stereoscopic content boundaries without requiring complex processing of the entire image frame.
3Ease of operation
If the 3D display automatically switches to stereoscopic display mode, then the user experience is improved, but the risk of incorrect mode activation increases
Solution Approach 1:
The patent applies intermediary by introducing a specific pattern border as a mediating element between the video content and the 3D display system. This border acts as a reliable signal that triggers automatic mode switching only when actually present, preventing false activations. The intermediary border provides a clear, unambiguous indicator that distinguishes genuine stereoscopic content from regular 2D content, ensuring accurate mode activation while maintaining ease of automatic switching.

AI summary
An electronic apparatus and a stereoscopic image display method thereof are disclosed. The method is adapted to the electronic apparatus including a 3D display and includes the following steps. A display frame including a streaming image is obtained. A specific pattern border surrounding the streaming image in the display frame is detected by performing a line detection. In response to the specific pattern border appearing in the display frame, a stereoscopic format image is generated based on the display frame and the specific pattern border. In response to the specific pattern border appearing in the display frame, the 3D display is controlled to operate in a stereoscopic display mode to display the stereoscopic format image.
