Image Reading Apparatus Orientation for Unsupported Languages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image reading apparatuses struggle to correctly orient and display characters from documents in languages not supported by the character recognition unit, leading to incorrect automatic image orientation and user confusion.
Innovation Solution
An image reading apparatus with a reading unit, character recognition unit, and display unit that allows users to select a language for display, includes an image-orientation changing unit to rotate or specify the orientation of characters, and a recognizable-language acquisition unit to determine if the language is supported, ensuring accurate orientation and display of characters even for unsupported languages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the character recognition unit is used to automatically orient image data, then the orientation accuracy is improved for supported languages, but the system fails to correctly orient characters in unsupported languages
Solution Approach 1:
The patent introduces an intermediary component (the display unit showing orientation information) that mediates between the character recognition unit and the user. When the character recognition unit cannot recognize a language, the system uses the display unit to show orientation indicators (such as icons or text) that guide the user on how to correctly orient the document, thus resolving the contradiction between maintaining automatic orientation accuracy and supporting multiple languages.
2Ease of operation
If the system performs automatic image orientation for all languages, then the ease of operation is improved, but the reliability of orientation decreases for unsupported languages
Solution Approach 1:
The patent implements a dynamic system that adapts its behavior based on language recognition. When the character recognition unit successfully recognizes a language, the system performs automatic orientation. When recognition fails, the system dynamically changes to display orientation guidance information on the display unit, allowing the user to manually orient the document. This dynamic adaptation maintains ease of operation while ensuring reliability across different language scenarios.
3Ease of operation
If the display unit shows orientation information for unsupported languages, then the user experience is improved, but the device complexity increases
Solution Approach 1:
The patent makes the display unit multi-functional by using it for both normal display purposes and for showing orientation information when character recognition fails. This universal approach allows the system to improve user experience for unsupported languages without adding dedicated hardware components, thus avoiding increased device complexity while still providing comprehensive orientation guidance.

AI summary
An image reading apparatus includes a reading unit, a character recognition unit, and a display unit for a display according to a language which is set. The reading unit reads out a document and generates image data. The character recognition unit recognizes a character included in the image data in order to orient the image data upright. The display unit displays information specifying an orientation of the character in the document with respect to the reading unit, when the language which is set is a language which is not recognizable by the character recognition unit.
