Image File Segmentation for Storage Limit Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reading apparatuses face challenges in processing and storing image files generated from large media, as the file size often exceeds a set upper limit, leading to storage limitations.
Innovation Solution
The reading apparatus divides the image file into multiple smaller files, associates them for storage, and includes functions for combining and outputting these files, allowing for successful storage and output without file size limitations, using a processor to manage and associate the files through thumbnail image data and dashed line boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reading apparatus stores image files generated from large media, then the complete image data can be preserved, but the file size exceeds the storage upper limit
Solution Approach 1:
The patent divides a large image file into multiple smaller image data units, each within the storage upper limit. The processor segments the image data into first image data, second image data, and subsequent units, storing each separately with associated metadata to maintain completeness while adhering to size constraints.
Solution Approach 2:
The patent embeds metadata containing segmentation information, storage location data, and reconstruction instructions within the storage system structure. This nested metadata layer enables the system to manage and reconstruct divided image files without requiring external management systems.
2Quantity of substance
If the reading apparatus divides image files into smaller units for storage, then the file size limit is satisfied, but the system complexity increases
Solution Approach 1:
The processor performs preliminary segmentation and metadata generation during the initial storage phase, organizing image data into manageable units with embedded instructions. This advance preparation simplifies subsequent retrieval and reconstruction operations, as the system only needs to follow pre-established metadata guidance rather than performing complex analysis during reconstruction.
Solution Approach 2:
The patent introduces metadata as an intermediary layer between the divided image data units and the storage/retrieval process. This metadata contains segmentation information, storage locations, and reconstruction instructions, acting as a mediator that simplifies the management of divided files without requiring complex processing logic in the main system.
3Measurement precision
If the reading apparatus stores divided image files with associated metadata, then the files can be retrieved and reconstructed accurately, but the storage space requirement increases
Solution Approach 1:
The patent stores comprehensive metadata only for the first image data unit, which contains segmentation information and reconstruction instructions. Subsequent image data units require minimal or no additional metadata, as their storage locations and parameters are derived from the first unit's metadata. This local quality approach ensures reconstruction accuracy while minimizing redundant storage of metadata.

Data Source
AI summary
A reading apparatus includes a storage configured to store data in the storage, a reader configured to optically read a medium, and a processor configured to, in response to the reading of the medium by the reader, acquire a set of read data based on the result of the reading, generate an image file based on the acquired set of read data, and allow the storage to store in itself the generated image file. Further, the processor includes the function of, when generating the image file, generating a plurality of image files resulting from a division that allows the file size of each of the plurality of image files to be smaller than a size upper limit, and of allowing the storage to store in itself the generated plurality of image files in a state in which the plurality of image files are associated with one another.
