Music Score Display Device Segmentation for Detail Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional music score display devices face challenges in displaying detailed notes and musical notation effectively, particularly in large scores with multiple parts, as enlarging a small area compromises visibility of the entire score, making it difficult to recognize pitches and other elements.
Innovation Solution
A music score display device that allows users to designate and enlarge specific portions of the score without reducing the visibility of the entire score by setting a source region for enlargement and a separate display destination region on the screen, ensuring the enlarged portion is displayed without overlapping or obscuring the rest of the score.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a small area in the music score is enlarged to clearly see details, then the visibility of details is improved, but the screen fails to show the entire score, resulting in poorer visibility of the overall score
Solution Approach 1:
The display screen is segmented into multiple independent display areas: a first display area showing the entire music score at normal size, and a second display area showing an enlarged view of a specific designated portion. This segmentation allows both the overall score and detailed portions to be visible simultaneously without interfering with each other.
2Area of stationary object
If the music score is displayed in a large area for enhanced visibility of the entire score, then the visibility of the overall score is improved, but it is hard to see details in the music score
Solution Approach 1:
The solution transitions from a single-dimensional display (either entire score OR detailed portion) to a two-dimensional display layout where the entire score occupies one region and the enlarged detailed portion occupies another region on the same screen. This dimensional approach allows both views to coexist without compromising either visibility of the whole or clarity of details.
3Area of stationary object
If a music score involving a number of parts is displayed with short distances between staves, then the entire score fits on the screen, but it is difficult to recognize the pitches of the respective notes
Solution Approach 1:
The display is segmented into an overview area showing all staves in compact form and a magnified area showing a selected portion with increased vertical spacing. This segmentation allows the score to fit on screen while providing a separate view where pitch recognition is facilitated by expanded spacing between staves and lines.

AI summary
The CPU in a music score display device includes: a source region setting unit that sets a source region based on a desired portion designated in a music score displayed on a screen, the source region of the music score being an object to be enlarged and displayed; a display destination region setting unit that sets a display destination region of the screen, the display destination region corresponding to the source region; and a display control unit that extracts the music score in the source region, and enlarges and displays the extracted music score in the display destination region on the screen.
