Conversion Time Prediction for Page Group Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for predicting conversion processing time in image forming apparatuses struggle to accurately account for nested relationships and transparency effects in page group data, leading to reduced RIP processing speed or errors, especially when dealing with complex hierarchical structures in PDF format.
Innovation Solution
A conversion time prediction apparatus that analyzes the degree of reuse of plane components, acquires data blocks, and calculates predicted conversion processing time by multiplying the conversion time of a data block by a preset coefficient, allowing for accurate prediction and notification of appropriateness, even when the number of plane data pieces is less than the unit plane number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nested relationship among page components becomes complicated with many hierarchical levels, then the structure can represent complex designs, but the RIP processing speed is reduced or errors occur
Solution Approach 1:
The system performs preliminary analysis of the page group data to detect complicated nested relationships and transparency effects before RIP processing begins. By identifying problematic structures in advance, the system can warn operators or adjust processing parameters beforehand, preventing processing delays and errors while maintaining the ability to represent complex designs.
2Ease of manufacture
If existing prediction methods are used that do not consider transparency effects and nested relationships, then the prediction process is simple, but the predicted conversion time is inaccurate
Solution Approach 1:
The system performs preliminary analysis to detect transparency effects and nested relationships in page group data before conversion processing. By identifying these characteristics in advance, the system can accurately predict conversion time based on the detected complexity factors, providing both accuracy and operator awareness without requiring complex real-time adjustments during processing.
3Ease of operation
If only the predicted conversion time is provided without analysis results, then the information is simple to present, but the operator cannot easily ascertain the appropriateness of the page group data
Solution Approach 1:
The system provides feedback to the operator by displaying both the predicted conversion time and the analysis results regarding transparency effects and nested relationships. This dual information presentation enables operators to assess the appropriateness of page group data while maintaining simple operation through automated detection and clear presentation of relevant metrics.

AI summary
Page-group data indicating many pages is analyzed to acquire the degree of reuse of page components as an analysis result. A set of page data pieces in the page-group data is acquired as a data block, the number of the pieces corresponding to a unit page number that is the number of pages to be processed collectively as a single task when a conversion processor in a system actually converts the page-group data into drawing data. A predetermined conversion processor converts the data block into drawing data to acquire a conversion processing time. A predicted value of a conversion processing time required for the conversion processor in the system to actually convert the page-group data is accurately obtained using the conversion processing time of the data block. An operator is notified of the analysis result and the predicted value and can easily ascertain the appropriateness of the page-group data.
