A second feature is that it includes a page unit in which a configured page is a unit and a part unit composed of parts such as a plurality of musical instruments.

  In addition, when an operation for moving the display area of the score is performed by the input means, if the screen movement mode is in measure units, instead of the measure currently displayed in the display area, When the display area is moved to display other bars that are connected to the downstream side, and the screen movement mode is in units of columns, instead of the stage currently displayed in the display area, the upstream or downstream side of the music If the display area is moved so as to display other stages that are connected to each other, and the screen movement mode is a page unit, it is connected to the upstream or downstream side of the music instead of the page currently displayed in the display area. A third feature is that the display area is moved to display other pages.

  A fourth feature is that other measures / columns / pages displayed in response to the moving operation are displayed at the same positions as the display positions before the movement.

  Further, when the screen movement mode is the part unit and the operation for moving the score display area is performed by the input means, the current display area is maintained while maintaining the position of the currently displayed measure. There is a fifth feature in that other parts that are not displayed are displayed.

  In addition, when the current display area already displays the upstream or downstream portion of the music corresponding to the screen movement mode, or another part, even if there is an input from the input means A sixth feature is that the current display area is not changed.

  A seventh feature is that the input means is an external device of the computer or a touch panel screen.

  An eighth feature is that selection of the screen movement mode is executed by selection of an icon displayed on the screen.

  Furthermore, there is a ninth feature in that the selection of the screen movement mode is executed according to the start point and the movement amount or movement direction of the movement operation by the input means.

  According to a first feature, in a score display program for displaying a score composed of a plurality of continuous bars on a screen, a function for selecting a screen movement mode to be applied when changing a score display area, and input means When the operation of moving the display area of the score displayed on the screen is performed by the computer, the function of displaying the display area that is not currently displayed is executed according to the selected screen movement mode. By switching the screen display quickly according to the screen movement mode, it is possible to efficiently display and edit the score.

  According to the second feature, the screen movement mode includes a bar unit having the bar as a unit, a stage unit having a stage composed of a plurality of bars connected in the horizontal direction, and a vertical direction. It includes a page unit with a page composed of a plurality of rows arranged in a unit, and a part unit made up of parts such as multiple instruments, so that it can be quickly displayed in bars, columns, pages, and parts.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a functional block diagram showing a configuration of hardware 1 for executing a score display program according to an embodiment of the present invention. The score display program is installed in the hardware 1 such as a personal computer or a tablet-type terminal. The score image is displayed on the display device 3 at an arbitrary enlargement ratio so that the score data can be edited and played. In response to an input operation by the device 2, a process of moving (scrolling) the display position of the score image displayed on the display device 3 is executed.

  The hardware 1 includes an input operation detection unit 5 that detects a user's movement operation by the input device 2, a movement coordinate detection unit 4 that detects a movement coordinate based on input information detected by the input operation detection unit 5, and an input operation A screen movement mode setting unit 6 for setting the screen movement mode based on the input information detected by the detection unit 5, a screen movement mode storage unit 9 for storing the screen movement mode set by the screen movement mode setting unit 6, browsing, A musical score information storage unit 7 for storing musical score data for editing and the like is included. A score image generating unit 8 that generates a score image to be displayed on the display device 3 based on the score data generates a score image after movement based on output information from the screen movement mode storage unit 9 and the movement coordinate detection unit 4. To do.

  The input device 2 and the display device 3 can be general mice and displays if the hardware 1 is a personal computer. When the hardware 1 is a tablet terminal or the like to which a touch panel display is applied, the touch panel display also serves as the input device 2 and the display device 3. Furthermore, the hardware 1 can include a speaker for playing the musical score data, and can also be provided with a connection unit for connecting to an electronic piano or the like by wire or wireless. When the hardware 1 is connected to an electronic piano, the musical score data stored in the musical score information storage unit 7 can be demo-played, or the user's performance can be evaluated by comparing it with model data.

  FIG. 2 is an example of a score image displayed on the display device 3. This figure shows the overall structure of a one-page score. A plurality of bars A are connected in the horizontal direction to form a stage B, and the stage B forms a page D by being arranged in the vertical direction. When there are a plurality of parts such as musical instruments, they are connected in the vertical direction as shown by parts C1, C2, C3... (7 parts in this figure) to form one stage B. A gap area 10 is provided between the upper and lower stave area 11, and a blank area 12 is provided outside the staff area 11 and the gap area 10. The movement coordinate detection unit 4 (see FIG. 1) of the hardware 1 indicates where the start point of the movement operation exists, in addition to the bar A, the stage B, and the page D, the stave area 11, the gap area 10, and the margin area 12. It is configured so that it can be determined in combination with the information.

  The musical score display program according to the present embodiment is a unit of measure A in addition to a pan function that moves in units of pixels of a conventionally known screen when the position of the display area is arbitrarily changed based on the operation of the input device 2. From “bar unit” having one column B, “page unit” having page D as one unit, or “part unit” having parts C1, C2,. The screen moving mode can be arbitrarily selected and applied.

  FIG. 3 is an example of a score display displayed on the display device 3 by the score display program. A control bar 31 provided below the display area 30 includes a display magnification slider 27 for changing the display magnification of the score displayed in the display area 30 and a page number slider 28 for changing the page of the displayed score. Is provided. The horizontal scroll bar 26 arranged at the upper end of the control bar 31 is automatically hidden together with a vertical scroll bar (not shown) when the magnification or display position does not require scrolling when displaying a score. It becomes.

  The icon bar 29 provided at the top of the display area 30 has, from the left, a pan function icon 21 that imitates the shape of a hand, a bar unit icon 22 that imitates bars that are connected horizontally, and a part that is aligned vertically. An imitated part unit icon 23, a step unit icon 24 imitating a column arranged in the vertical direction, and a page unit icon 25 imitating a plurality of pages are provided. By selecting one of the icons, a predetermined screen movement mode is set by the screen movement mode setting unit 6 (FIG. 1) of the hardware 1.

  When changing the position of the score displayed in the display area 30, after selecting one of the icons, a drag operation of pressing the mouse button and sliding the mouse inside the display area 30, or a finger A swipe operation for tracing in a predetermined direction on the screen or a flick operation for bringing a finger in a predetermined direction on the screen is performed. A pointer 40 is displayed in the display area 30, and the starting point of the moving operation is the position of the pointer 40 at the start of the drag operation or the position where the finger touches the screen at the start of the swipe / flick operation.

  3 and 4 show a procedure for moving the score display using the pan function. When the pan function icon 21 is selected, the screen movement mode function is set to the pan function. A conventionally known pan function is to move the current display position to another position by grabbing the score with a mouse or touch panel operation and moving it to another position. 3 and 4, the movement start point 41 is set by pressing a mouse button or by touching the screen with a finger. From here, a drag operation or a swipe operation corresponding to the direction and length indicated by the arrow 43 is performed. The musical score display is moved by the amount indicated by the arrow 44 in FIG. If a flick operation is performed when the pan function icon is selected, the screen moves by an amount corresponding to the momentum of repelling the finger.

  Here, when editing symbols or notes in a score, it is possible to increase the display magnification of the score. For example, in order to proceed to the next page while displaying one measure at the center, In addition to having to drag and swipe many times, it becomes difficult to grasp the current position of the displayed score, so in reality, once you have reduced the display magnification, move it to the desired position, In many cases, the image was enlarged again.

  In addition, when editing a measure, if you want to refer to not only the measures on the upstream or downstream side of the song, but also other steps and other parts corresponding to the current display position, There was a problem that it was difficult to find a desired position.

  The musical score display program according to the present invention solves such a problem of the pan function, and switches to movement in bar units, column units, page units, and part units to quickly move to a desired position on the score. It is possible.

  5 and 6 are diagrams showing the procedure for moving on the score in units of measures. When the measure unit icon 22 on the icon bar 29 is selected, the screen movement mode is switched to the measure unit. In this state, if a drag / flick operation (hereinafter sometimes simply referred to as a movement operation) is performed in the left-right direction, the music can be quickly moved to a measure on the upstream side or downstream side of the music. This figure shows a state where the pointer 40 is moved to the fifth bar on the downstream side by performing a leftward movement operation indicated by an arrow 50 from a state where the pointer 40 is superimposed on the fourth bar. In the example of this figure, since the fifth measure does not exist in the page before the movement, the screen is moved across the pages. When the screen movement as described above is executed, the score image generation unit 8 (see FIG. 1) of the hardware 1 starts the drag / flick operation detected by the movement coordinate detection unit 4, the movement direction, and the movement amount. The score image after movement is generated based on the above.

  When moving in bars, steps, pages, or parts, flicking is more intuitive than swiping, and mouse dragging is an operation that releases the button while moving the mouse quickly. Is suitable. Note that this figure shows an example in which the score display is moved by a left-right movement operation. However, an up-down operation, for example, a downward operation moves to an upstream bar and an upward operation downstream. It may be set to move to a bar.

  7 and 8 are diagrams showing a procedure for moving on a score in part units. When the part unit icon 23 on the icon bar 29 is selected, the screen movement mode is switched to the part unit. In this state, if a moving operation is performed in the vertical direction, it is possible to quickly move to the upper and lower parts of the currently displayed part. In this figure, by moving the pointer 40 over the first piano in the fifth bar and moving upward as indicated by the arrow 51, the pointer 40 moves to the second piano located below the first piano in the same bar. It shows the state to do. If there are no upper and lower parts in the page, the screen can be moved across the pages. Further, even when a part unit is selected, it may be set to move to the upper part by an operation in the left-right direction, that is, to the right, and to move to the lower part by an operation to the left.

  FIG. 9 is a flowchart showing a procedure in which the screen movement process is executed by the score display program according to the present invention. The following processing is realized by the operation of each component shown in the block diagram of FIG.

  In step S1, the input operation detection unit 5 detects an input operation from the input device 2, and in step S2, it is determined whether or not the start coordinate of the input operation (movement operation) is detected by the movement coordinate detection unit 4. Is done. The start coordinates are an X coordinate and a Y coordinate corresponding to the start position of the drag operation of the mouse or the position where the finger touches the screen at the start of the swipe / flick operation.

  If an affirmative determination is made in step S2, the process proceeds to step S8, the start coordinates are stored, and the process returns to step S1. If a negative determination is made in step S2, that is, if it is determined that the start coordinates of the moving operation are detected and stored, the process proceeds to step S3.

  In step S3, it is determined whether or not the end coordinates of the moving operation have been detected. If an affirmative determination is made in step S3, the process proceeds to step S4 to store the end coordinates. The end coordinates are an X coordinate and a Y coordinate corresponding to a position where the button is released in the drag operation of the mouse or a position where the finger is released from the screen at the end of the swipe / flick operation. If the speed of the drag operation or swipe / flick operation during selection of the four screen movement modes excluding the pan function is smaller than a predetermined value, it may be determined that the screen movement is not performed because it is an erroneous operation. Good.

  On the other hand, if a negative determination is made in step S3, the process proceeds to step S9, in which it is determined whether or not the screen movement mode has been changed by selecting an icon. If an affirmative determination is made in step S9, the process proceeds to step S10, the screen movement mode set by the screen movement mode setting unit 6 is stored in the screen movement mode storage unit 9, and the process returns to step S1. On the other hand, if a negative determination is made in step S9, the process returns to step S1 while maintaining the currently set screen movement mode.

  When the end coordinates are stored in step S4, storage of both the start coordinates and end coordinates of the moving operation is completed. In response to this, in step S5, the score image generation unit 8 updates the score image. Specifically, the score image generation unit 8 creates a score image after the movement operation based on the output information from the screen movement mode storage unit 9 and the movement coordinate detection unit 4, and replaces the score image before the movement operation with a new score image. Update processing is performed.

  In step S6, the screen display of the display device 3 is updated with the updated score image, and the process proceeds to step S7. In step S7, it is determined whether or not the score display program has ended. If a negative determination is made, the process returns to step S1, and if an affirmative determination is made, a series of control is ended.

  FIG. 10 is a conceptual diagram showing a mode of screen movement when the screen movement mode is in bar units and column units. When a movement operation is performed, screen movement according to the selected screen movement mode is executed. This is because the screen E is displayed in the display area 30 centering on the fifth bar, and when the bar unit mode is selected, the movement operation to the left is performed as indicated by the left arrow 52b. While moving horizontally to the screen E1 centering on the measure, it is represented by horizontally moving to the screen E2 centering on the fourth measure by performing a rightward movement operation as indicated by the right arrow 52a. Although not shown, when there is no upstream or downstream measure in the horizontal direction, it moves to the last measure in the previous stage or the first measure in the subsequent stage, and corresponds to the move operation to the currently displayed page. When there is no measure to be played, you can move across pages.

  Similarly, when the screen F centering on the twelfth measure is displayed in the display area 30 and the step unit mode is selected, the downward movement operation is performed as indicated by the down arrow 53b. While moving vertically to the screen F1 across the 8th to 9th bars, as shown by the up arrow 53a, the screen is moved vertically to the screen F2 centering on the 15th bar. Although not shown, when the page unit mode is selected, the page is moved to the previous page or the next page corresponding to the currently displayed display area.

  The screen movement mode described above is set so that when the musical score display program according to the present invention detects a movement operation, the screen is moved to another area that is not currently displayed according to the screen movement mode. Corresponds to being. In other words, even if a movement operation is detected, if another area corresponding to the movement operation is already displayed in the display area 30, it is set not to move the screen. Further, the other measures / columns / pages displayed in accordance with the moving operation are set to be displayed at the same positions as the display positions before the movement. Thereby, even if the display area is switched in accordance with the movement operation, it is not necessary to move the line of sight in order to search for a desired portion, and the work efficiency can be improved.

  FIG. 11 is a conceptual diagram including an example in which the screen is not moved even when the moving operation is performed. When the screen G surrounding the entire first to sixth bars is displayed in the display area 30 and the bar unit mode is selected, the screen is moved even if the moving operation is performed with the second bar as the starting point. Absent. This is because the third and fourth bars upstream and downstream of the second bar are already displayed on the screen G.

  Further, when the screen H surrounding the entire fourth to fifth stages is displayed in the display area 30 and the unit operation mode is selected, when the moving operation is performed with the fourth stage as a starting point, an arrow is displayed. The screen is moved only in accordance with the downward movement operation indicated by 54. This is because the fifth stage is already displayed on the screen H for the upward movement operation. Similarly, when the moving operation is performed starting from the fifth stage, the screen is moved only in accordance with the upward movement operation indicated by the arrow 55 (switching to the first stage of the next page). This is because the fourth stage is already displayed on the screen H for the downward movement operation. With such settings, unnecessary screen changes can be suppressed. However, the present invention is not limited to this, and the screen may be always moved only by the moving direction of the start coordinate and the end coordinate regardless of the start coordinate bar or step position.

  FIG. 12 is a diagram illustrating a modification of the screen movement mode selection method. In the above-described embodiment, the screen movement mode is set by selecting one of the five icons. However, in this modification, the measure unit, part unit, It is possible to automatically select the screen movement mode in units of columns and pages.

  In the illustrated example, as indicated by an arrow 56, when the start position of the moving operation is in the staff notation region 11 and the moving amount is smaller than a predetermined value T, it is determined as a measure unit. Further, as indicated by an arrow 57, when the start position of the moving operation is in the staff notation region 11 and the moving amount is larger than the predetermined value T, it is determined as a part unit. Then, as indicated by arrows 58 and 59, when the starting position of the moving operation is in the gap area 10, it is determined as a step unit, and further, as indicated by the arrow 60, the starting position of the moving operation is displayed in the blank area 12. In some cases, the page unit is determined. According to such setting, the screen movement mode can be automatically selected only by the way of moving operation, the display area can be moved more quickly, and browsing and editing can be performed smoothly.

  In the above example, the selection of the screen movement mode is automatically performed using the start position and the movement amount. However, a method of performing the selection in the start position and the movement direction is also conceivable. For example, there is a method in which the start position of the moving operation is in the staff notation region 11 and is moved in the bar unit when moved in the left-right direction, and in the part unit when moved in the vertical direction. In that case, the step unit and page unit may be the same as described above.

  With the above-described configuration, the score display program according to the present invention has a function of selecting a screen movement mode to be applied when changing a score display area, and a score display area displayed on the screen by an input unit. When an operation to move is performed, the computer executes a function to display a display area that is not currently displayed on the screen according to the screen movement mode, and when the screen movement mode is in bar units, it is currently displayed in the display area. Instead of bars, other bars that are connected upstream or downstream of the music are displayed, and when the screen movement mode is in units of columns, it is connected to the upstream or downstream side of the music instead of the level currently displayed in the display area. When another screen is displayed and the screen movement mode is page unit, another page connected upstream or downstream of the song is displayed instead of the page currently displayed in the display area. Therefore, the screen display can be quickly switched according to the selected screen movement mode in section units, column units, page units, and part units, so that, for example, a desired measure can be displayed even when a score is enlarged and edited. It is possible to quickly move to the stage and increase work efficiency.

  The configuration of the hardware, the display device, and the input device, the mode of the screen displayed on the display device, the rectangle of the display area, the shape of the icon for selecting the screen movement mode, the mode of the score data, etc. are not limited to the above embodiment. Various modifications are possible. For example, the screen movement mode may be configured to include some of measures, steps, parts, and pages. Furthermore, in the case of a keyboard instrument with a wide range, since it is one part as a grand staff that vertically connects the staves for bass and treble parts, a screen movement mode called staves is provided in addition to the above. Also good. In that case, when one part is composed of a plurality of staffs, the screen can be moved in units of staffs.
