Image Processing Apparatus Storage Segmentation for Input Output Jobs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems face inefficiencies in recording and managing input/output data and reference information, leading to poor storage capacity utilization and increased storage needs, especially during printing or transmission processes.
Innovation Solution
An image processing apparatus and method that separates the storage of image data and reference information, storing only reference information for output jobs and actual image data for input jobs, optimizing storage usage and retrieval efficiency within a security unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all input/output image data are stored in the recording device, then complete record of image processing is achieved, but storage capacity consumption increases significantly
Solution Approach 1:
The patent segments the storage of image data by job type: input jobs store actual image data in the recording device, while output jobs store only reference information (job ID, user ID, timestamp) in the same device. This segmentation resolves the contradiction by reducing redundant storage of the same image data for output operations, thereby decreasing storage capacity consumption while maintaining complete records through the linkage of reference information to actual image data.
Solution Approach 2:
The patent creates a reference copy for output jobs that points to the original image data stored during input jobs. Instead of storing duplicate full image data for output operations, the system stores a reference copy (metadata linking to original data), which reduces storage capacity requirements while preserving the ability to retrieve and trace image processing information.
2Reliability
If real image is recorded every time during BOX printing or broadcast transmission, then complete processing history is maintained, but recording efficiency decreases
Solution Approach 1:
The patent segments recording operations by job type: input jobs trigger full image data recording, while output jobs trigger only reference information recording. This segmentation improves recording efficiency by avoiding redundant recording operations during output phases, while maintaining processing history completeness through the reference information linkage to original image data.
Solution Approach 2:
The patent discards the need to record full image data again during output jobs, retaining only the reference information (job ID, user ID, timestamp). The original image data is recovered through the reference linkage when needed, thereby improving recording efficiency while preserving processing history completeness.
3Quantity of substance
If large storage capacity recording device is used, then all image data can be stored, but device complexity and cost increase
Solution Approach 1:
The patent segments storage requirements by implementing different storage strategies for input and output jobs within the same recording device. Input jobs store full image data, while output jobs store only reference information. This segmentation reduces the overall storage capacity requirement compared to storing all image data, thereby reducing device complexity and cost while maintaining necessary storage capacity for the segmented data types.
Solution Approach 2:
The patent uses reference copies for output jobs that link to original image data, avoiding the need for large storage capacity to hold duplicate full image data. This copying approach reduces the storage requirements and consequently reduces device complexity and cost, while still enabling complete traceability through the reference linkage mechanism.

AI summary
An image processing apparatus includes a job execution unit configured to execute at least one of an input job accompanied by inputting of image data and an output job unaccompanied by inputting of image data, an image data storage unit configured to store image data in a predetermined memory, a reference information storage unit configured to store reference information to the image data stored in the memory in the same memory, and a control unit configured to control the image data storage unit to newly store image data in the memory when the job executed by the job execution unit is an input job, and the reference information storage unit to store the reference information to the image data stored in the memory without newly storing image data in the memory when the job executed by the job execution unit is an output job.
