Communication Apparatus Metadata Retrieval via Intermediary Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems between digital cameras and mobile devices do not adequately facilitate the retrieval and display of metadata associated with image data, requiring users to manually analyze image headers, which is inefficient and not user-friendly.
Innovation Solution
A communication apparatus that includes a communication unit to request and receive metadata from an external device, allowing metadata to be displayed without the need for users to analyze image headers, using APIs to manage and transmit data efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the digital camera reads and analyzes the header of image data to transmit metadata to the mobile phone, then the mobile phone can access metadata information, but the user does not necessarily grasp how the metadata is recorded and how it can be browsed from the mobile phone
Solution Approach 1:
The patent introduces an intermediary system (the communication apparatus with display control unit) that mediates between the digital camera's metadata storage and the mobile phone's display capabilities. This intermediary automatically retrieves metadata from the camera, processes it through the communication unit, and presents it in a user-friendly format on the mobile phone display, bridging the gap between raw data storage and user comprehension
Solution Approach 2:
The system enables self-service by allowing the mobile phone to autonomously request and receive metadata from the digital camera through the communication unit without requiring manual header analysis by the user. The display control unit automatically manages the metadata presentation, making the process transparent and effortless for the end user
2Productivity
If the mobile phone receives and stores image data from the digital camera, then the user can store images remotely, but it requires the digital camera to read and analyze headers and transmit required information
Solution Approach 1:
The patent extracts only the necessary metadata information from the complete image data header structure and transmits only this extracted information to the mobile phone. The communication unit selectively requests and receives specific metadata fields (such as date, time, location) without requiring transmission of the entire header or full image data, reducing complexity while maintaining functionality
Solution Approach 2:
The system performs preliminary action by having the digital camera prepare and store metadata in the header area in advance, organized in a structured format. When the mobile phone needs metadata, the pre-organized data can be quickly retrieved and transmitted without requiring real-time header parsing or analysis during the transfer process
Data Source
AI summary
A communication apparatus includes a communication unit that requests image data from an external apparatus and receives image data from an external apparatus in response to the request, a display control unit that displays the received image data on a display unit, and a receiving unit that receives an instruction for selecting displayed image data. The communication unit further requests, from the external apparatus, metadata of selected image data and receives the metadata without receiving the image data. The metadata is recorded in a header area of a file containing the image data stored in the external apparatus.
