Image Capture Metadata Synchronization with Identified Video Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems struggle to correctly synchronize video and metadata in real-time synthesis, especially when multiple apparatuses are connected to computers, leading to potential misidentification and incorrect combinations.
Innovation Solution
The image capturing apparatus includes a video output unit and a metadata output unit that add unique identification information, such as an IP address or serial number, to the video signal, ensuring correct synchronization and identification of the apparatus, using standardized ancillary data formats like SMPTE ST12.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If video and metadata are output from the same unit, then the structure is simple, but the reliability of synchronization and identification deteriorates
Solution Approach 1:
The patent divides the output function into separate units: a video output unit that outputs video signals and a metadata output unit that outputs metadata. This segmentation allows each unit to be optimized for its specific function while maintaining reliable synchronization through the inclusion of identification information in the video signal that corresponds to the metadata output.
2Adaptability or versatility
If multiple image capturing apparatuses are connected to computers without identification information, then the connection is flexible, but the measurement precision of apparatus identification deteriorates
Solution Approach 1:
The patent introduces identification information as an intermediary element within the video signal that serves as a mediator between the image capturing apparatus and the computer. This identification information enables precise apparatus identification while maintaining connection flexibility, as the identification data is embedded within the existing video signal transmission path rather than requiring separate identification protocols.
Data Source
AI summary
An image capturing apparatus includes an imaging device configured to capture an image of a subject, a video output unit configured to output a video signal output from the imaging unit, and a metadata output unit configured to output metadata including information related to the video signal, the metadata output unit being different from the video output unit. The video output unit adds information that can identify an individual of the image capturing apparatus to the video signal and outputs the video signal.
