Engineering Contradiction Analysis
1Measurement precision
If conventional ink estimation methods are used (performing rasterization and halftoning), then ink usage can be estimated, but the computational intensity is excessively high
Solution Approach 1:
The patent extracts only the essential information needed for ink estimation from the complex rasterization and halftoning process. Instead of performing the complete image processing pipeline, the invention directly analyzes the bitmap data to determine ink usage, removing unnecessary computational steps while preserving estimation accuracy
Solution Approach 2:
The patent performs preliminary analysis of the bitmap data structure to identify patterns and characteristics that directly correlate with ink usage. By pre-processing the data to extract only the relevant features (drop sizes, pel distributions) before calculation, the method avoids the computational burden of full rasterization while maintaining estimation precision
2Measurement precision
If conventional ink estimation methods are used (performing rasterization and halftoning), then ink usage can be estimated, but the processing time increases
Solution Approach 1:
The patent extracts only the essential information needed for ink estimation from the complex rasterization and halftoning process. Instead of performing the complete image processing pipeline, the invention directly analyzes the bitmap data to determine ink usage, removing unnecessary computational steps while preserving estimation accuracy
Solution Approach 2:
The patent skips the time-consuming intermediate steps of full rasterization and halftoning by directly analyzing the bitmap input. The method rushes through the estimation process by using simplified calculations based on bitmap characteristics, achieving rapid ink usage estimation without sacrificing precision
