OCR Display Apparatus Distinguishing Recognition and Comparison Results
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in distinguishing between the results of character recognition and comparison in optical character recognition (OCR) processes, as the displayed candidates for character strings are not clearly differentiated between recognition and comparison outcomes.
Innovation Solution
An information processing apparatus is designed to display the result of recognition and the result of comparison next to each other, allowing users to clearly differentiate between the two through a dedicated display process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If character recognition results and comparison results are displayed together without differentiation, then the display is compact, but the user cannot distinguish between recognition results and comparison results
Solution Approach 1:
The patent applies color changes by displaying character recognition results and comparison results in different colors. Specifically, the display unit shows the character string image, recognition result, and comparison result with distinct color coding, allowing users to easily differentiate between these different types of information without adding complex structural elements to the display device.
2Measurement precision
If only character recognition results are displayed, then the display is simple, but the user cannot verify whether the recognition result matches the expected character string
Solution Approach 1:
The patent applies segmentation by dividing the display into distinct regions: the character string image region, the recognition result region, and the comparison result region. This segmented layout allows the display to show multiple types of information (original image, recognition outcome, and verification result) without creating a cluttered or overwhelming interface, as each element has its designated space.
3Reliability
If character recognition is performed without comparison, then the processing speed is fast, but the reliability of the recognized character string is reduced
Solution Approach 1:
The patent applies preliminary action by performing character string comparison based on form definition information before finalizing the recognition result. The comparison unit compares the recognized character string against expected patterns or definitions stored in the system, ensuring reliability is maintained. This preliminary verification step is integrated into the workflow without significantly impacting overall processing speed, as the comparison uses pre-defined reference data.
Data Source
AI summary
An information processing apparatus includes a processor configured to control a display such that a result of recognition, which is obtained by recognizing an image on which a character string is written, and a result of comparison, which is obtained by comparing the result of recognition with a database registered in advance, are displayed next to each other.
