Abstract

PURPOSE:To enable automatic music block copy preparation by providing a design information input means, a font memory means, a font display means, a format conversion means and a vector image format storage means. CONSTITUTION:When a special symbol is designed, a screen where a music is displayed is switched over to a screen for design creation by issuance of a design command, and an external enclosure line is drawn on the screen, tracing the movement of a mouse. Next, when a command to daub an area inside the external enclosure line in black is issued, an area adjoining to an adjacent area to the external enclosure line is daubed sequentially without smearing the adjacent area according to an automatic judgement. Next, the dot image format of a character font in the smeared area is converted to a vector image format to segment the external enclosure line. The length of the segmented units is used as a vector value. Then a vector with a directional value is obtained based on the vector value, and this vector image format is stored into a storage device. After this, a drawn design is expressed in the form of a music. Thus a high quality music block copy can be prepared without depending on manual work.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a musical score draft creation device that inputs musical score data and creates a musical score draft based on the input musical score data.

(Prior Art and Problems to be Solved by the Invention) Conventionally, various attempts have been made to develop musical score draft creation devices that input musical score data and create a musical score draft based on the input musical score data. It's here.

As a result, a personal computer type device for creating musical scores was developed, and by connecting an output device for creating a manuscript to a personal computer, it was possible to easily create a manuscript. By the way, over the long history of music scores, the way they are drawn (so-called musical notation) has gradually become standardized, and although it has reached the present day, it is not 100% standardized. In some cases, new symbols not found in previous musical scores or symbols that are modified versions of conventional symbols may be drawn. For example, a flat circle (10
) and guitar chords (11). Moreover, in the future, there will be an increasing number of special musical scores that cannot be included within the scope of conventional musical notation, such as graphic musical scores and modern musical scores.

In general, conventional computer-based music score drafting devices store font images of characters and symbols that often appear in music scores (for example, pound signs, flat signs, forte signs, etc.) in advance in a storage device. , the method is to output it from an output device. For this reason, special symbols such as those mentioned above are often not stored in storage devices, and it has been impossible to process such symbols with a computer.

Previously, if such symbols appeared on a manuscript, the worker would draw them directly on the block by hand. As a result, this becomes a factor that impedes complete automation of musical score draft creation, and also creates a situation in which manual work is difficult when special symbols such as those mentioned above occur frequently.

(Means for Solving the Problems) In order to solve the problems as described above, the present invention provides a design information input means for inputting design information such as special symbols, and a method for drawing the input design information. font memory means for storing character fonts for the purpose of the present invention; font display means for displaying the extracted character fonts on the screen; converting the dot image format displayed on the screen in the character fonts into a vector image format; The present invention provides a musical score draft creation device characterized by having a format conversion means for converting the format, and a vector image format storage means for storing the vector image format.

(Function) The present invention aims to save labor by completely automating the manual process of creating the sheet music version, and it uses a computer to create special symbols, which conventionally required manual work.
The Aidit Design System (hereinafter referred to as CAD system) has been introduced into the musical score draft creation device, and for special symbols that are not stored in the storage device, the input person can design special symbols as dot images on the screen while inputting. However, after designing, the dot image format is converted into a vector image format and stored in memory so that it can be handled like other stored symbols.

(Example) Next, an embodiment of the musical score draft creation apparatus based on the present invention will be described based on the drawings. FIG. 1 is a schematic diagram of the musical score draft creation apparatus based on the present invention. (1 ) allows you to press multiple notes at the same time to input the original note data.
Furthermore, it is a piano keyboard that has a diatonic scale key group and a chromatic scale key group that can press notes with accidentals attached, and (2) has a plurality of function keys and alphanumeric keys, and has a coded key group. This is a function keyboard for inputting lyrics etc. (3) is a memory for temporarily storing musical score data inputted from a piano keyboard and a function keyboard, and for performing predetermined calculations on the musical score data stored in the memory and creating a musical score based on the calculation results. This is a personal computer having a control unit.

(4) is a display unit that displays the created musical score on the screen.

(5) is a printer that prints a copy of the displayed musical score.

(6) is an input mouse for drawing design information such as special symbols on the display screen (4).

FIG. 2 is a flowchart of arithmetic processing performed by the control section to design special symbols. The flow of the arithmetic processing shown in FIG. 2 will be explained with reference to FIG. 3 and FIG. 5. The flattened circle 0ω in FIG. 3 is usually not a symbol stored in advance in a storage device, such as the treble clef.

Then, the operator issues a design command and switches the screen on which the musical score was displayed to the design creation screen (Sl).

Next, as shown in Figure 4 (a), draw an outline on the screen according to the movement of the mouse (6) (32). The outline is drawn as a collection of dots.

Next, the operator instructs the operator to fill in the inside of the outline with black, and the system automatically makes decisions one after another, such as leaving the area adjacent to the outline unfilled and filling in the area adjacent to it. S3). The dot image format of the character font in the filled area as shown in FIG. 4(b) is converted into a vector image format (S4). That is, as shown in FIG. 5, the outline is subdivided, and the length of each subdivided unit is used as a vector quantity, which is given directionality and used as a vector. The direction of the vector is decided so that it goes counterclockwise on the outside of the outline and clockwise on the inside. This vector image format is stored in the storage device (S5). Finally, the design drawn in vector image format is displayed on the musical score, and the process ends (S6).

(Effects) According to the present invention, it is possible to save labor by completely automating the manual process of creating a sheet music version, and it is possible to save labor by completely automating the process of creating a sheet music version. However, it is now possible to quickly create high-quality sheet music versions without relying on any manual work.
