Camera Preview Stream Transfer for Pose Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inefficiencies when taking photos or videos with smartphones, particularly due to the limited size of the LCD screen and distance from the screen, making it difficult to check poses and adjust camera parameters, leading to repeated attempts and wasted time, especially when someone else is taking the photos or videos.
Innovation Solution
A method and system that allows clients in a communication session to share preview streams, enabling clients selecting the preview function to adjust camera parameters of clients taking photos or videos, and establish a relationship table to manage communication sessions and camera parameter adjustments, allowing for real-time feedback and pose confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users check poses on a small LCD screen, then they can confirm their appearance, but the small screen size and distance make it difficult to see clearly, leading to repeated attempts and wasted time
Solution Approach 1:
The patent extends the preview functionality from the local LCD screen to a remote display dimension via network transmission. The preview stream is transmitted over a network to another device's display, allowing users to view their pose from a different spatial dimension and distance, thereby improving visibility without being constrained by the smartphone's small screen size.
Solution Approach 2:
The patent introduces a network transmission system as an intermediary between the camera and the user's view. Instead of directly viewing the preview on the smartphone screen, the user's pose is captured by the camera, transmitted through the network, and displayed on a remote device, allowing for better observation without requiring the user to be close to the smartphone.
2Ease of operation
If someone else takes photos or videos for users, then users cannot see the smartphone screen to check their poses, but this requires repeated confirmation and waiting time
Solution Approach 1:
The network transmission system serves as an intermediary that bridges the gap between the photographer and the subject. The subject can view their own preview stream on their own device while the photographer operates the camera on the other device, eliminating the need for the subject to physically interact with or view the photographer's screen.
Solution Approach 2:
The system provides real-time visual feedback to the user through the transmitted preview stream. Users can continuously monitor their pose and expression in real-time on their own device while someone else operates the camera, allowing for immediate adjustments without interrupting the photography process.
3Weight of moving object
If the smartphone screen is far from users, then portability is improved, but users cannot clearly see their poses on the screen
Solution Approach 1:
The patent creates a new viewing dimension by transmitting the preview stream over a network to a remote display device. This allows the smartphone to remain small and portable while the user can view their pose on a larger or more conveniently positioned display through the network connection, effectively decoupling the camera's physical size from the viewing experience.

AI summary
A transferring preview stream method provides services to share a preview stream from one client selecting a function of taking photos or videos to another client selecting a function of preview. Clients engaging in a communication session and executing a camera function are configured to periodically receive current location information provided by their location-aware components and transfer it to system for establishing a predetermined area based on their current location information, camera function group and relationship table. The method may be intended to set up transmission sessions between clients in the camera function group for transferring preview streams from clients selecting the function of taking photos or videos to another clients selecting the function of preview. The clients selecting the function of preview may be able to adjust the camera parameters of another clients selecting the function of taking photos or videos in order to confirm user's satisfactory poses and get good quality of photos or videos.
