Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple binarization processing methods are used to generate binary image data, then the quality and adaptability of image processing is improved, but determining the appropriate compression processing method becomes complex
Solution Approach 1:
The system counts the number of times each binarization processing method is used and uses this feedback information to automatically select the appropriate compression processing method. The compression method selection unit monitors binarization method usage and adjusts compression method selection based on this feedback, resolving the complexity of manual selection while maintaining adaptability.
Solution Approach 2:
The system performs self-selection of compression processing methods by automatically determining which binarization method was used and choosing the corresponding optimal compression method without external intervention. The compression method selection unit autonomously matches compression methods to binarization methods based on usage counts, eliminating the need for complex external control.
2Speed
If compression processing is executed without selecting the appropriate method, then processing speed is maintained, but compression efficiency and productivity deteriorate
Solution Approach 1:
The system performs preliminary counting of binarization method usage during the binarization processing phase, so that when compression processing is needed, the appropriate compression method is already identified. This preliminary action allows for efficient compression method selection without adding significant processing time, maintaining speed while improving productivity.
3Device complexity
If the compression processing method does not match the binarization processing method, then device complexity is reduced, but data loss and processing reliability worsen
Solution Approach 1:
The system changes the parameter of compression method selection based on the binarization method used. By adjusting the compression method parameter according to binarization method usage counts, the system maintains simplicity in the overall device structure while ensuring reliability through appropriate method matching. The parameter change is automatic and based on measurable usage statistics.

AI summary
A control device includes a binarization processing unit which executes binarization processing on original image data using first and second types of binarization processing methods, and a compression processing unit which executes compression processing on the binary image data using one of a first type of compression processing method appropriate for compression of the binary image data generated using the first type of binarization processing method, and a second type of compression processing method appropriate for compression of the binary image data generated using the second type of binarization processing method. When the binary image data is generated using the first and second types of binarization processing methods, the compression processing unit selects the compression processing method according to a number of using times of the first type of binarization processing method and a number of using times of the second type of binarization processing method.
