Solution Overview

Problem

Users face difficulty in selecting a proper viewpoint when viewing 360-degree images, as current image display apparatuses lack an efficient method to guide users to optimal compositions, leading to manual and time-consuming viewpoint adjustments.

Innovation Solution

An image display apparatus and method that utilize a composition detection parameter set learned through neural networks to determine a recommended viewpoint based on user input and category information, allowing for automatic movement to a view point with a proper composition, incorporating user-preferred compositions and external server assistance for enhanced accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual viewpoint adjustment is used in 360-degree image display, then users can freely explore different angles, but the process becomes time-consuming and user effort increases

Engineering Contradiction:

Improveease of viewpoint selectionVSAvoidtime for viewpoint adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs automatic viewpoint determination and adjustment based on composition detection parameters and user preferences, allowing the apparatus to serve itself in selecting optimal viewpoints without requiring continuous manual user input

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical viewpoint adjustment with an automated computational system that uses neural networks and composition detection algorithms to automatically determine and switch between optimal viewpoints

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated viewpoint selection is implemented, then user effort and time are reduced, but system complexity increases due to composition detection parameters and neural networks

Engineering Contradiction:

Improveviewpoint selection efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system pre-calculates and stores composition detection parameters and optimal viewpoints during image processing, so that during actual viewing, the apparatus can quickly retrieve and apply these pre-determined parameters without performing complex real-time calculations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces composition detection parameters as an intermediary that bridges the gap between raw 360-degree image data and optimal viewpoint selection, simplifying the decision-making process by using these intermediate parameters to guide viewpoint determination

Inventive Principle:

Principle #24Intermediary (Mediator)
