Filter Condition Selection for Reading Apparatuses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large number of setting conditions in filter condition tables for reading apparatuses leads to increased capturing times, making it inefficient to set the optimum capturing condition.
Innovation Solution
A selection apparatus and method that determine whether a reading target is readable with various combinations of setting conditions for filtering, selecting the optimal condition based on these determinations, reducing the number of necessary captures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all setting conditions in the filter condition table are tested, then the optimum capturing condition can be determined, but the number of capturing operations increases significantly
Solution Approach 1:
The patent segments the filter condition table into multiple groups based on similarity of setting conditions. Instead of testing all conditions individually, the system divides them into manageable segments and performs representative sampling within each group, thereby reducing the total number of capturing operations while maintaining accurate determination of optimum conditions.
Solution Approach 2:
The patent applies partial action by testing only a subset of setting conditions rather than all conditions. By selecting representative conditions from each group and performing capturing operations only on these selected conditions, the system achieves sufficient accuracy for determining optimum conditions without the excessive time cost of testing every possible setting.
2Measurement precision
If multiple stages of intensity level filtering are applied, then reading accuracy improves, but the number of setting conditions increases to a large number
Solution Approach 1:
The patent segments the complex filter condition table with multiple intensity levels into smaller groups based on similarity. This segmentation reduces the apparent complexity by organizing conditions hierarchically, allowing the system to work with manageable subsets while preserving the multi-stage filtering capability for accurate reading.
Solution Approach 2:
The patent applies partial action by not testing all intensity levels for every filter type. Instead, it selects representative intensity levels from each filter type and combines them in a reduced number of test cases, thereby maintaining reading accuracy through multi-stage filtering while avoiding the combinatorial explosion of setting conditions.
3Reliability
If comprehensive filtering conditions are tested, then the reliability of reading results improves, but the time required to set optimum condition increases
Solution Approach 1:
The patent segments the condition testing process into groups of similar settings. By determining optimum conditions within each segment first and then comparing across segments, the system maintains reliable reading results through comprehensive evaluation while reducing total testing time through structured organization of the search space.
Solution Approach 2:
The patent performs preliminary action by pre-grouping similar filter conditions before the actual testing begins. This preliminary organization allows the system to efficiently navigate through the condition space, performing capturing operations on representative samples from each group, thereby achieving reliable results faster than exhaustive testing would allow.

AI summary
A selection apparatus capable of efficiently selecting an optimum setting condition for filtering is provided. The selection apparatus is an apparatus that selects a setting condition for filtering to be performed on a reading target. The selection apparatus includes: a determiner that determines whether the reading target is readable with each of a plurality of combinations selected from among combinations of all setting conditions for at least two types of filtering; and a selector that selects a setting condition for the filtering based on a result of the determination by the determiner.
