Time Slice Video Server Dynamic Object Refocusing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Time slice video techniques are limited to capturing objects at a fixed focal position and cannot capture events occurring outside this position, restricting their applicability.
Innovation Solution
A video providing server and user device system that receives a first time slice video, allows user selection of a second object, extracts feature points based on color information, generates a second time slice video focused on the selected object, and transmits it to the user device for display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If time slice techniques are applied only to objects at a fixed focal position, then the quality of the time slice video for the focused object is improved, but the ability to capture objects outside the focal position deteriorates
Solution Approach 1:
The patent implements dynamic object selection and refocusing capability that allows the system to shift focus from the original focal object to any other object in the scene. The server receives user input to select a second object and dynamically generates a new time slice video with the second object as the focus, enabling the system to adapt its focal point based on user requirements rather than being fixed on a single object.
Solution Approach 2:
The system changes the focal parameter of the time slice video by extracting feature points of the selected second object and regenerating the time slice video with updated focus parameters. This parameter transformation allows the same set of camera images to produce different time slice videos focused on different objects, effectively changing the focus position without physical camera movement.
2Manufacturing precision
If multiple cameras are used to capture images at different angles, then the 3D time slice effect is improved, but the complexity of the system increases
Solution Approach 1:
The patent introduces a video providing server as an intermediary that handles the complex processing of multiple camera images. The server receives images from multiple cameras, performs feature point extraction, and generates the time slice video with the selected object as focus. This intermediary architecture separates the complex processing tasks from the camera system and user device, making the overall system more manageable despite the use of multiple cameras.
Solution Approach 2:
The system creates a virtual copy of the time slice video with a different focal object by processing the same set of camera images through feature point extraction and image combination. Instead of requiring additional physical cameras for each focal object, the system generates multiple versions of the time slice video from the same camera data, each focused on a different selected object.

AI summary
A video providing server that provides a time slice video includes a receiving unit that receives a first time slice video that is generated from images captured by multiple cameras having a focus on a first object; an input unit that receives, from a user device, a selection of a second object among multiple objects displayed in the first time slice video; a feature point extraction unit that extracts feature points of the selected second object; a generation unit that generates a second time slice video having a focus on the second object based on the extracted feature points of the second object; and a transmitting unit that transmits, to the user device, the second time slice video having the focus on the second object.
