Parallel Image Analysis Processing for Print Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses face performance issues when performing monochrome printing of color documents, as they require additional time for image analysis and enhancement, which can degrade printing performance and make it difficult to set analysis image processing as default due to time constraints.
Innovation Solution
The apparatus includes an image acquisition unit, a normal image processing unit, an analysis image processing unit, and a merge processing unit that perform normal and analysis image processing in parallel, merging the results immediately before printing, allowing for default execution of analysis image processing and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If analysis image processing is performed sequentially after normal image processing, then image analysis accuracy is improved, but printing performance and processing speed deteriorate
Solution Approach 1:
The analysis image processing unit performs analysis image processing in parallel with normal image processing, completing analysis work beforehand rather than sequentially after printing preparation. This allows both analysis accuracy and printing performance to be maintained by eliminating the sequential waiting time.
2Productivity
If analysis image processing is performed in parallel with normal image processing, then processing speed is improved, but device complexity increases
Solution Approach 1:
The image processing apparatus is divided into distinct functional units: normal image processing unit and analysis image processing unit. Each unit handles specific tasks independently, allowing parallel operation while maintaining clear functional separation. This segmentation enables faster processing without requiring complete redesign of the entire system.
Solution Approach 2:
A merge processing unit serves as an intermediary that combines the outputs from normal image processing and analysis image processing. This mediator coordinates the parallel processing streams and integrates their results, managing the complexity of parallel operations without requiring direct interaction between the processing units.
3Manufacturing precision
If analysis image processing is set as default, then image quality and analysis capability are improved, but processing time increases
Solution Approach 1:
Analysis image processing runs continuously in parallel with normal image processing rather than being executed as a separate subsequent step. This continuous parallel execution ensures that analysis work progresses simultaneously with printing preparation, maintaining high image quality without adding sequential delays to the overall processing time.

AI summary
Provided is an image processing apparatus that improves the performance when performing image processing accompanying an analysis. An image acquisition unit acquires processing image data for performing processing. A normal image processing unit performs normal image processing for normal output on the processing image data acquired by the image acquisition unit and outputs the normal image data. An analysis image processing unit performs analysis image processing accompanied by analysis in parallel with the normal image processing by the normal image processing unit and outputs the analysis image data. A merge processing unit merges the normal image data output by the normal image processing unit and the analysis image data output by the analysis image processing unit and outputs print data for printing.
