Automatic 3D Image Playback Switching via Glasses Detection

Solution Overview

Problem

Existing 3D image playback methods require users to manually switch between 2D and 3D modes or wear specific glasses, making them inconvenient for use.

Innovation Solution

An image playback system that captures glasses contour images and compares them with stored data to automatically determine whether to play 3D or 2D images, using an image capturing module, a comparing device, and a control device to control the display accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual mode switching is required for 3D and 2D image playback, then the system can support both modes, but the ease of operation deteriorates

Engineering Contradiction:

Improvesupport for 3D and 2D playback modesVSAvoidmanual mode switching operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects whether the user is wearing 3D glasses by capturing an image of the user's face and comparing it with stored glasses contour images. Based on this automatic detection, the system self-determines whether to play 3D or 2D images without requiring manual user input, thus improving ease of operation while maintaining adaptability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from the image capture device to automatically adjust the playback mode. The captured face image is processed to detect glasses contours, and this feedback information is used to automatically switch between 3D and 2D playback modes, eliminating the need for manual switching operations

Inventive Principle:

Principle #23Feedback

2Reliability

If 3D glasses are required for 3D image viewing, then 3D image quality is improved, but the ease of operation deteriorates due to additional equipment and setup requirements

Engineering Contradiction:

Improve3D image viewing qualityVSAvoidglasses wearing and mode switching

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system automatically detects whether the user is wearing 3D glasses by capturing an image of the user's face and comparing it with stored glasses contour images. Based on this automatic detection, the system self-determines whether to play 3D or 2D images without requiring manual user input, thus improving ease of operation while maintaining adaptability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The image capture device and processing system act as intermediaries between the user and the playback system. Instead of requiring the user to manually switch modes or remember to wear glasses, the intermediary system automatically detects the glasses presence and adjusts playback accordingly, simplifying the user experience

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An image playback method includes starting an image display module, detecting glasses data in a predetermined range, comparing the detected glasses data with a set of data to generate a first comparison result, and the image display module playing a 3D image or a 2D image according to the first comparison result.
