Automatic Monochrome Image Contrast Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print controlling apparatuses burden users by requiring them to arbitrarily select filters for converting color images to monochrome images, leading to excessive user intervention.
Innovation Solution
A print controlling apparatus that obtains a color image, generates multiple monochrome images using different calculations, calculates contrast, and selects the calculation with the strongest contrast to automatically convert and print the monochrome image, reducing user burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user arbitrarily selects the filter to convert the color image to a monochrome image, then the user can control the conversion process, but it puts an excessive burden on the user
Solution Approach 1:
The system automatically performs monochrome image conversion by evaluating multiple filter options and selecting the optimal one based on contrast calculation, eliminating the need for user intervention in filter selection while maintaining high-quality conversion results
Solution Approach 2:
The system changes the parameter of filter selection from user-defined to system-defined by automatically calculating contrast values for different filter options and selecting the filter that produces the monochrome image with the strongest contrast
2Manufacturing precision
If multiple monochrome images are generated for preprocessing with different calculations, then the contrast quality is improved, but the processing complexity increases
Solution Approach 1:
The system performs preliminary generation of multiple monochrome images with different filter calculations before final selection, allowing contrast evaluation to be done on预处理 images rather than full-resolution images, thus reducing overall processing complexity
Solution Approach 2:
The system generates multiple monochrome images exceeding the single needed output, but uses contrast calculation to evaluate and select only the best one, ensuring optimal contrast quality while the excess processing is performed on low-resolution preprocessing images

AI summary
A method to configure an apparatus to apply a plurality of mono colorization filters to a low resolution version of a color image. A contrast value is determined for each application of the mono colorization filters. The mono colorization filter achieving the highest contrast value is applied to a high resolution version of the color image to produce a high contrast monochrome image. The high contrast monochrome image is then printed by the apparatus.
