Image Data Identifier Preliminary Transfer for Portable Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face delays and security concerns when saving image data from image processing apparatuses to portable storage media, as they need to wait for the processing to complete and leave the device inserted, which is undesirable.
Innovation Solution
A method that issues an identifier for image data, writes it to the storage medium before completion, associates the data with the identifier, and decrypts it for secure storage, allowing users to remove the device and reconnect later for secure data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user waits for image data to be completely generated before writing to storage medium, then data integrity is ensured, but user wait time increases and productivity decreases
Solution Approach 1:
The system performs preliminary actions by writing the identifier to the storage medium before the image data generation is complete. This allows the user to remove the storage medium immediately after insertion without waiting for the lengthy image processing to finish, while the system continues generating the data in the background and will automatically complete the transfer when ready.
2Reliability
If the storage medium remains inserted in the image processing apparatus during data generation, then data transfer completeness is ensured, but security risks increase due to user exposure to the device
Solution Approach 1:
The system performs the critical action of writing the identifier to the storage medium before the user needs to leave. Once the identifier is written, the storage medium can be safely removed without compromising data integrity, as the system will automatically complete the data transfer when the image generation is finished, eliminating the need for the user to remain at the device.
Solution Approach 2:
The identifier acts as an intermediary between the storage medium and the image data. Instead of transferring the complete image data immediately (which would require the medium to remain inserted), the system first transfers a small identifier that serves as a placeholder and reference. This intermediary enables the user to remove the medium safely while the actual data transfer completes automatically in the background.
3Adaptability or versatility
If complex image processing is performed to improve processing capability, then image quality and functionality are enhanced, but processing time increases causing user waiting
Solution Approach 1:
The system separates the identifier writing action from the complete data transfer process. The identifier, which is small and can be written quickly, is transferred preliminarily to enable immediate user departure. The complex image processing continues in the background without blocking the user, and the remaining data transfer completes automatically when processing finishes, thus eliminating the perceived waiting time while maintaining high processing capabilities.

AI summary
A method for outputting image data generated by an image processing apparatus to a portable storage medium connected to an interface is provided. The method includes the following steps of: issuing an identifier of the image data; writing the identifier into the storage medium without waiting for the image data to be generated completely; after generating the image data, associating the image data with the identifier and storing the image data in a storage portion; reading out the identifier from the storage medium when the storage medium is connected to the interface again; and writing, into the storage medium, the image data stored in the storage portion in association with the identifier thus read out.
