Musical Score Image Analyzer for Capturing Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for correcting curved distortion in images of musical scores cannot quantitatively evaluate the suitability of the capturing direction and do not automatically adjust the device to minimize distortion, making it difficult for users to capture high-quality images.
Innovation Solution
A musical score image analyzer that includes a processor and memory to detect musical symbols, specify symbol columns, calculate indices related to image capturing, and instruct a capturing device to adjust its operation to ensure optimal image capture based on these indices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually adjusts the capturing direction while visually checking distortion, then the capturing operation can be performed, but it is difficult to maintain suitable capturing direction and the process is complex
Solution Approach 1:
The system automatically evaluates capturing direction suitability and provides feedback without user intervention. The evaluation unit calculates distortion metrics and the feedback unit guides the user, making the system self-regulating rather than requiring manual adjustment and visual inspection
Solution Approach 2:
The system provides real-time feedback about capturing direction quality through calculated distortion metrics. This feedback loop allows users to adjust their capturing angle based on quantitative guidance rather than trial-and-error visual inspection
2Manufacturing precision
If automated capturing instruction is implemented based on index evaluation, then image quality is improved, but the device complexity increases
Solution Approach 1:
The system divides the image analysis process into distinct functional units: distortion calculation unit, evaluation unit, and feedback unit. Each unit performs a specific task (calculating distortion metrics, evaluating suitability, providing guidance), making the complex system manageable and maintainable through modular design
Solution Approach 2:
The evaluation unit acts as an intermediary between the distortion calculation and the final capturing decision. It processes the raw distortion metrics and translates them into actionable guidance, bridging the gap between technical measurement and user action

AI summary
A musical score image analyzer includes a processor and a memory having stored thereon instructions executable by the processor to cause the musical score image analyzer to perform: detecting musical symbols in a musical score image obtained by capturing a musical score having a plurality of staffs arranged in parallel to each other and the musical symbols respectively disposed in prescribed positions in the staffs; specifying a symbol column having the detected musical symbols which are arranged in a column; calculating an index relating an image capturing based on the symbol column; and instructing a capturing device to perform capturing operation of a still image for the musical score image when the index satisfies a prescribed condition.
