Mobile Terminal Wide-Angle VR Image Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack the capability to effectively generate and transmit virtual reality (VR) images with a wide enough angle of view for immersive experiences, limiting user interaction and content availability.
Innovation Solution
A mobile terminal system that generates VR images by combining multiple images from various angles using cameras and transmits these images to a receiving terminal, which renders them for display in a VR device, allowing users to experience virtual reality with a wider field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple images from various angles are combined to generate VR images, then the angle of view and immersive experience are improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent divides the VR image generation process into multiple segments: capturing individual images from different angles using separate cameras, transmitting these images through communication networks, and combining them at the receiving end. This segmentation allows each component to be optimized independently while achieving the overall goal of wide-angle VR imaging without requiring a single complex device to handle all functions simultaneously
Solution Approach 2:
The patent implements a nested structure where multiple camera systems are integrated within the mobile terminal, with each camera capturing a specific angular segment. The received images are then nested within a composite VR image structure, where individual angle images are combined to form the complete panoramic view. This nesting approach allows systematic organization of multiple imaging components while maintaining manageable system complexity
2Adaptability or versatility
If VR images are transmitted between mobile terminals, then content accessibility is improved, but the transmission bandwidth and data requirements increase
Solution Approach 1:
The patent transmits only the necessary angular image segments required to reconstruct the VR experience rather than complete high-resolution images. By sending partial image data from multiple angles that can be synthesized into the full VR view, the system achieves wide-angle content accessibility while significantly reducing the total data transmission volume compared to transmitting complete panoramic images
Solution Approach 2:
The patent creates simplified copies of the original scene from different angular perspectives and transmits these copied views between terminals. Instead of transmitting the entire original high-fidelity VR content, the system transmits multiple angular copies that can be reassembled at the receiving end, reducing bandwidth requirements while maintaining content accessibility across multiple devices

AI summary
A mobile terminal including a camera; a display; a wireless communication unit; and a controller configured to control the wireless communication unit to transmit a first signal requesting a video call to provide a virtual reality (VR) image to an external device, the VR image having an angle of view equal to or greater than a preset degree, generate the VR image based on a plurality of images obtained using the camera, control the wireless communication unit to receive a preset second signal from the external device, and control the wireless communication unit to transmit a third signal including the generated VR image to the external device in response to the second signal.
