Color Conversion Switching for RIP Processing Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The prolonged raster image processing (RIP) time in the data printing industry, particularly due to frequent color conversion processes when handling high-resolution bitmap images, leads to inefficiencies in the printing process, especially when multiple layered bitmap images are involved, resulting in unnecessary computation waste.
Innovation Solution
An information processing apparatus with a first calculation unit to determine the number of color conversions required for original document data, a tag bit generation unit to associate attribute information with pixels, and a color conversion switching unit to optimize color conversion processes based on the comparison between the number of color conversions for the original and raster data, minimizing unnecessary conversions and processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color conversion process is performed for each pixel of high-resolution bitmap images during RIP processing, then image quality and color accuracy are improved, but processing time is significantly prolonged
Solution Approach 1:
The system performs preliminary calculations to determine the number of color conversions required for both original document data and raster data before actually executing the color conversion process. This preliminary assessment allows the system to optimize the color conversion strategy by comparing the calculated numbers and selecting the more efficient processing path, thereby reducing unnecessary color conversion operations while maintaining quality.
Solution Approach 2:
The invention changes the parameter of color conversion approach by dynamically selecting between converting original document data directly or converting raster data after RIP processing, based on the calculated number of color conversions. This parameter change allows the system to adapt the processing method to minimize time loss while preserving color accuracy requirements.
2Adaptability or versatility
If color conversion process is performed multiple times for layered bitmap images, then color adjustment flexibility is improved, but computation resources are wasted and processing time is prolonged
Solution Approach 1:
The system performs preliminary calculations to determine the number of color conversions required for both original document data and raster data before actually executing the color conversion process. This preliminary assessment allows the system to optimize the color conversion strategy by comparing the calculated numbers and selecting the more efficient processing path, thereby reducing unnecessary color conversion operations while maintaining quality.
Solution Approach 2:
The system uses feedback from the calculated number of color conversions to determine the optimal processing path. By comparing the number of color conversions for original document data versus raster data, the system receives feedback about which approach is more efficient and adjusts its behavior accordingly, avoiding redundant color conversion operations on layered images.
3Ease of operation
If color conversion process is performed for raster data after RIP processing, then color adjustment is enabled, but processing time is extended

AI summary
An information processing apparatus calculates a number of times of color conversion performed for an object included in an original document data as a first number of color conversions as the; generates tag bits including attribute information for each pixel of raster data and calculates a number of pixels that are included in the raster data and that have an object attribute indicated by the tag bits as a second number of color conversions; compares, when generating new raster data with color adjustment performed for the original document data, the first number of color conversions with the second number of color conversions; performs color conversion either for the original document data when the first number of color conversions is smaller than the second number, or for the generated new raster data when the second number of color conversions is smaller than the first number.
