Inspection System Margin Display for Barcode Reading Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection systems face challenges in ensuring a sufficient margin area for reading character strings and barcodes, leading to decreased recognition rates and inaccurate readings due to insufficient margin settings during the inspection process.
Innovation Solution
An information processing apparatus is configured with a display controller that visually indicates a necessary margin area for extraction processing, allowing users to set and verify the inspection area, thereby ensuring accurate data extraction and reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inspection area is set without visual margin indication, then the setting process is simple, but the recognition rate decreases and reading accuracy deteriorates
Solution Approach 1:
The patent introduces a margin area display as an intermediary visual element between the inspection area setting and the actual reading process. This display shows the relationship between the inspection area and the required margin area, acting as a mediator that guides users to set appropriate margins without complicating the overall setting process.
Solution Approach 2:
The patent replaces the manual trial-and-error method of setting inspection areas with a visual display system that automatically shows the required margin area. This substitution transforms the mechanical adjustment process into an information-based guidance system, improving accuracy without adding operational complexity.
2Device complexity
If the margin area is not visually displayed, then the display content is simple, but the reading accuracy of character strings and barcodes deteriorates
Solution Approach 1:
The patent segments the display content into distinct functional areas: the inspection area and the margin area. This segmentation allows the display to show both the set inspection area and the required margin area separately, making the complex information structured and easier to interpret while ensuring reading accuracy.
Solution Approach 2:
The patent adds a visual dimension to the margin area concept by displaying it as a separate graphical element. This transforms the abstract margin requirement into a visible spatial representation, allowing users to understand the required spacing without increasing the fundamental complexity of the inspection system.
3Loss of time
If the inspection area is set without margin consideration, then the setting process is quick, but the data extraction accuracy decreases
Solution Approach 1:
The patent implements preliminary action by displaying the required margin area before the user finalizes the inspection area setting. This allows users to adjust their settings based on the margin requirement information provided in advance, ensuring accurate data extraction without requiring time-consuming trial and error after setting.

AI summary
An information processing apparatus includes one or more controllers having one or more processors and one or more memories, the one or more controllers being configured as an extractor configured to cause a reader to read a printed material sequentially conveyed from an image forming unit, and perform processing of extracting data from an image formed on the printed material, a display controller configured to display a received image on a display unit, and a setting unit configured to set, on the image displayed on the display unit, an area in which the extraction processing is performed. The display controller displays a margin area necessary for the extraction processing and identifiable with respect to the area set by the setting unit.
