Description

  The present invention relates to a setting apparatus and method for setting parameters using virtual operation objects displayed on a display unit in various devices such as an audio mixer.

  2. Description of the Related Art Conventionally, an electronic device such as an audio mixer or an electronic musical instrument has an operation element associated with various parameters, and the associated parameter value can be adjusted using the operation element. For example, as is well known, an audio mixer includes a number of controls including fader controls for volume control and knob controls for gain adjustment in individual channel strips. Japanese Patent Application Laid-Open No. H10-228707 describes adjusting a parameter value by using a virtual operator image displayed on a touch panel as an example of an operation interface of a mixer.

  Conventionally, when setting a parameter value in accordance with an operation of an operator, it is known that a change amount of a parameter value is changed in accordance with an operation amount, and coarse adjustment and fine adjustment are selectively used. In the present specification, the ratio for converting the operation amount of the operation element into the change amount of the parameter value is referred to as resolution. For example, in the following Patent Document 2, in an operation element capable of a rotation operation and an operation along the rotation axis of the rotation operation, one of two types of resolutions is set based on the pushing operation of the operation element. It is described.

  Patent Document 3 discloses a finger (contact point) for operating the virtual operation object as a method for changing the resolution of the operation of the seek bar for displaying and changing the playback time position such as a moving image or sound in a touch panel display. And changing the resolution according to the distance of the object. However, with this method, it is difficult to operate near the distance corresponding to the boundary where the resolution changes, and there is a possibility that the operation cannot be performed as intended. Also, if you want to pay attention to the virtual operation object, the finger that operates the virtual operation object will move away from the object. For example, pay attention to how far the finger is from the object. The operability may be impaired, for example.

  The present invention has been made in view of the above points, and an object of the present invention is to make it possible to easily and easily change the resolution of an operation in the control of parameter values using a virtual operation object.

  The present invention includes a step of displaying a virtual operation object, a step of detecting a user operation on the virtual operation object, a step of determining a form of the detected operation in response to the detection of the operation, Determining a resolution for converting an operation amount of a user operation on the virtual operation object into a change amount of a parameter value in accordance with the determined operation form; and the detected operation and the determination The method includes a step of changing a value of a parameter assigned to the virtual operation object in accordance with the determined resolution.

  According to the present invention, when the user performs an operation related to the virtual operation object in a certain operation form, the resolution for converting the operation amount into the change amount of the parameter value according to the operation form is reduced. The parameter value assigned to the virtual operation object is changed according to the operation and the determined resolution. Therefore, the resolution for converting the operation amount of the virtual operation object into the change amount of the parameter value can be selectively used only by properly using the operation form for changing the parameter value. Since it is not necessary to perform an operation for determining the resolution different from the operation of changing the parameter value, the resolution can be used in a simple and easy-to-understand manner. Further, since the resolution is changed by changing the form of the parameter value changing operation, it is possible to concentrate on the parameter value changing without diverting attention to the resolution changing operation.

  In addition, the present invention may be implemented and configured as a setting device including not only a method invention but also a component corresponding to each step constituting the method.

  According to the present invention, the resolution for converting the operation amount of the virtual operation object into the change amount of the parameter value can be selectively used by a simple and easy-to-understand method that only uses the operation form for changing the parameter value. Therefore, it is possible to easily and easily control the parameter value using the virtual operation object.

  FIG. 2 is a block diagram illustrating an example of an electrical hardware configuration of the acoustic signal processing device 100 in which the setting device 10 illustrated in FIG. 1 is incorporated.

The acoustic signal processing device 100 may be configured by a dedicated hardware device, or may be configured by a computer device that can execute an acoustic signal processing program, such as a general-purpose personal computer or a tablet terminal device. .

  Note that the acoustic signal processing apparatus 100 may include other components not shown, such as a network interface for connecting to a computer network.

  3A to 3E show examples of virtual operation objects displayed on the touch panel 3. In FIG. 3A, an operation element image simulating a fader operation element (“fader image”) is displayed as a virtual operation object 31 on the screen 30 of the touch panel 3. The virtual operation object 31 is configured to be able to move an image 32 representing a knob portion along a predetermined slide direction (left-right direction in FIG. 3). The position of the knob part image 32 corresponds to the parameter value assigned to the virtual operation object 31.

  FIG. 4 is a flowchart illustrating an example of processing executed by the CPU 1 when a touch operation is performed on the virtual operation object 31. The CPU 1 detects a contact point of one or more fingers performing a touch operation related to the virtual operation object 31 by the detection mechanism of the touch panel 3 (step S1). The touch operation is an operation for sliding the knob portion of the virtual operation object 31 (changing the parameter value). As an example, the CPU 1 may detect a contact point on the virtual operation object 31 as a touch operation on the virtual operation object 31. In another example, the CPU 1 may detect a contact point within a predetermined distance from the virtual operation object 31 as a touch operation on the virtual operation object 31. In another example, when the number of fingers performing a touch operation as described later is two or more, the CPU 1 determines that the virtual object 31 and the barycentric point of the finger performing the touch operation are The overlapping case may be detected as a touch operation on the virtual operation object 31. In another example, the CPU 1 may detect a touch operation on the virtual operation object 31 when the center of gravity is within a predetermined distance from the virtual operation object 31.

  In step S2, the CPU 1 counts the number of fingers performing a touch operation based on the detected contact point, and in step S3, based on the counted number of fingers, the user performs an operation on the virtual operation object 31. Determine the type of operation. As an example, the “operation form” is the number of fingers performing a touch operation, and step S3 determines whether the number of fingers is one or two. As another example, step S3 may determine whether the number of fingers is one or two or more. In that case, if there are three or more fingers, the CPU 1 may proceed with the processing assuming that the number of fingers is two.

  Then, the CPU 1 determines a resolution for converting the operation amount of the user operation into the change amount of the parameter value according to the determined operation mode (number of fingers) (step S4 or step S5). . For example, when the number of fingers is one, the CPU 1 determines the resolution as the first resolution (S4), and when the number of fingers is two, the resolution is different from the first resolution. Two resolutions are determined (S5). As an example, the first resolution is to convert a certain operation amount L into a parameter value change amount L, and the second resolution is to change a certain operation amount L by half that in the case of the first resolution. The amount is converted to L / 2. That is, the touch operation at the second resolution has a smaller parameter change amount with respect to the operation amount than the touch operation at the first resolution. In the specification, the touch operation at the first resolution is referred to as “normal operation”, and the touch operation at the second resolution is referred to as “fine operation”.

  When the user moves the touch operation, the CPU 1 detects an operation amount corresponding to the movement of the touch operation, and determines the operation amount of the detected touch operation based on the determined resolution. And the display of the virtual operation object 31 is updated according to the converted change amount, and the parameter value stored in the memory 2 is updated according to the change amount (step S6). ). “Moving a touch operation” refers to moving a finger touching the touch panel 3 on the touch panel 3 (moving a contact point). The detected operation amount of the touch operation is, for example, the moving direction and moving speed of the touch operation.

  For example, as shown in FIG. 3B, when the number of fingers performing the touch operation is one (only the contact point 33a is detected), the resolution is set to the first resolution (S4). When the user moves the touch operation (movement of the contact point 33a), the CPU 1 multiplies the moving speed of the touch operation by a first magnification “1” corresponding to the first resolution, The moving speed of the knob portion image 32 that follows the moving speed of the touch operation is obtained (S6). Then, the CPU 1 updates the display of the virtual operation object 31 so that the knob part image 32 moves at the converted movement speed, and the parameter 1 corresponds to the position of the moved knob part image 32. The value is updated (S6). For example, as shown in FIG. 3C, when the touch point 33a is moved by the moving distance L due to the movement of the touch operation, the knob portion image 32 is also moved by the distance L.

  On the other hand, as shown in FIG. 3D, when the number of fingers performing the touch operation is two (two contact points 33b and 33c are detected), the resolution is set to the second resolution (S5). ). When the user moves the touch operation (movement of the contact points 33b and 33c), the CPU 1 detects the movement of the center of gravity position 34 between the two contact points 33b and 33c, for example, thereby touching the two fingers. The movement speed of the touch operation is reduced by half by multiplying the detected movement speed of the touch operation by the second magnification “0.5” corresponding to the second resolution. The moving speed of the knob part image 32 converted to the speed is obtained (S6). Then, the CPU 1 updates the display of the virtual operation object 31 so that the knob portion image 32 moves at the converted moving speed, and corresponds to the position of the moved knob portion image 32. The parameter value is updated (S6). For example, as shown in FIG. 3E, if the gravity center position 34 is moved by the movement distance L due to the movement of the touch operation, the display position of the image 32 of the knob portion is moved by a half distance L / 2. . As described above, when the fine operation is performed with the second resolution, it is possible to finely and accurately adjust the parameter according to the movement of the touch operation. In other words, the parameter value does not change much with respect to the movement amount of the touch operation.

  As in this embodiment, when the fine operation (S5 and S6) using the second resolution is performed, the number of fingers to be used is increased (to two) compared to the normal operation (S4 and S6). According to the configuration, the user will feel as if he / she is operating a heavy object when performing a fine operation. Further, the “slowness” of the display movement of the knob portion image 32 according to the fine operation can visually give the user a feeling as if he / she is operating a heavy object. In this way, when performing a fine operation, it is as if a heavy object is being operated by the user's action (operation with two fingers) and visual (slowness of display movement of the knob portion image 32). By giving a sensation, the operational feeling of the parameter value changing operation using the virtual operation object 31 can be improved. In addition, the sensation as if operating a heavy object matches the small change in the parameter value with respect to the operation amount in the fine operation. Therefore, it is easy for the user to understand intuitively how to use the normal operation when the number of fingers is one and the fine operation when the number of fingers is two.

  As an example, the CPU 1 repeats steps S6 and S7 until all touch points are separated from the touch panel 3 (No in step S7), and updates the display and parameters of the virtual operation object 31 each time a movement of the touch operation is detected. Is changed (step S6). Steps S6 and S7 are repeated until all the touch points are separated from the touch panel 3, so that the user can touch at least one of the fingers performing the touch operation with the touch panel 3 to move the finger, The parameter value can be changed.

  When all the contact points are separated from the touch panel 3 (Yes in step S7), the CPU 1 ends the process of editing the parameter value (step S8). After step S1, the CPU 1 may end the process in FIG. 4 when all fingers performing the touch operation are separated from the touch panel 3 at any timing.

  As described above, the touch operation on the virtual operation object 31, that is, the operation of the touch operation according to the form (number of fingers) of the touch operation for changing the value of the parameter assigned to the virtual operation object 31. The first resolution or the second resolution can be used properly in order to convert the quantity into the change amount of the parameter value. Since it is not necessary to perform an operation for determining the resolution separately from the operation of changing the parameter value, the resolution can be used in a simple and easy-to-understand manner. Further, since the resolution change is performed by changing the number of fingers of the touch operation for changing the parameter value, it is possible to concentrate on the parameter value changing operation without diverting attention to the resolution changing operation. Therefore, the parameter value control using the virtual operation object 31 can be easily and easily performed.

  Next, as an example of a virtual operation object according to another embodiment, FIGS. 5A to 5E show an example of an operation screen of a parametric equalizer displayed on the screen 50 of the touch panel 3. A characteristic curve for adjusting the frequency characteristic is displayed as a virtual operation object 51 on the operation screen of the parametric equalizer. In FIG. 5A, the horizontal axis indicates the frequency band, and the vertical axis indicates the gain value of the volume level. The virtual operation object 51 (characteristic curve) includes three control points 52a, 52b, and 52c, and the center frequency for any three frequency bands is set by the left and right positions of the individual control points 52a, 52b, and 52c. And the gain value of a corresponding frequency band is set with the up-and-down position of each control point 52a, 52b, 52c.

  The user can select any one control point by a touch operation of one or more fingers, and can move the selected control point by moving the touch operation. FIG. 6 is a flowchart illustrating a processing example executed by the CPU 1 in response to a touch operation on the screen 50 of the touch panel 3. Steps S10 to S14 in FIG. 6 are substantially the same as steps S1 to S5. That is, the CPU 1 detects a touch operation and selects one control point based on the touch point of the touch operation (S10). Then, the CPU 1 counts the number of detected finger of the touch operation (S11), and determines whether the counted number of fingers is one or two (or two or more) (S12). In the case of one, the resolution is determined as the first resolution (S13), and in the case of two (or two or more), the resolution is determined as the second resolution (S13).

  The CPU 1 determines the parameter type to be adjusted according to the initial movement direction of the movement of the touch operation in steps S15 to S16. The initial movement is the first movement (movement) of the touch operation detected in S10. Specifically, the first movement refers to an initial touch operation movement performed within a certain predetermined time or a movement within a predetermined distance among the movement amount of the initial touch operation. The CPU 1 loops steps S11 to 13 until there is an initial movement (NO in step S15). Therefore, if the number of fingers is changed before the initial movement, the resolution is changed accordingly.

  When the initial motion is detected (Yes in step S15), the direction of the initial motion is determined (step S16). The initial movement direction is, for example, one of up and down and left and right directions. When the touch operation is moved in a direction other than the vertical direction or the horizontal direction (for example, an oblique direction), the CPU 1 regards the movement of the touch operation as corresponding to either the vertical direction or the horizontal direction. The operation amount detected in accordance with the movement (initial movement) of the touch operation is, for example, a moving direction and a moving speed.

  In step S17, the CPU 1 fixes the movement direction of the control point 52b in the determined initial movement direction and determines the parameter type to be controlled according to the initial movement direction. As described above, the left and right positions of the control point 52 are associated with the center frequency, and the up and down position is associated with the gain value. Therefore, when the initial movement direction is the left and right direction, the parameter type to be controlled is determined as the center frequency. When the initial movement direction is the vertical direction, the parameter type to be controlled is determined as a gain value. As a result, the control point 52b can be moved only in the fixed movement direction, and the parameter type to be controlled is fixed. Further, as an example, the CPU 1 performs guide display indicating the fixed moving direction on the touch panel 3 in response to fixing the moving direction of the control point 52 in step S17. Thereby, the fixed moving direction can be clearly shown to the user. The user can grasp which type of parameter is to be controlled and which direction the knob can be moved by displaying the moving direction.

  In step S18, as in step S6, the CPU 1 converts the operation amount (movement direction and movement speed) corresponding to the movement of the touch operation into a parameter value change amount based on the determined resolution. The display of the virtual operation object 31 is updated according to the converted change amount, and the parameter value stored in the memory 2 is updated according to the change amount. As an example, in step S18, the CPU 1 extracts only the component in the movement direction (that is, the initial movement direction) fixed in step S17 out of the operation amount corresponding to the movement of the touch operation, and the extracted The moving speed is converted into the change amount.

  Thereafter, every time the movement of the touch operation is detected (Yes in step S19), the CPU 1 performs the process of step S18. Therefore, the user can move the control point 52 only in the movement direction fixed by the initial movement direction, and change the value of the parameter fixed by the initial movement direction. When the number of fingers is changed (No in step S19, Yes in step S20), the CPU 1 returns the processing to step S12 to determine the resolution according to the changed number of fingers. The parameter value corresponding to the direction is changed. Then, until all the contact points are separated from the touch panel 3 (No in Step S21), the CPU 1 loops Steps S19 to S21. When all the contact points are separated from the touch panel 3 (Yes in Step S21), the CPU 1 The process for editing the parameter value is terminated (step S22).

  For example, as shown in FIG. 5B, when the control point 52b is selected by a touch operation of one finger (contact point 53a), the resolution is determined as the first resolution. When the initial movement direction of the touch operation is downward, as shown in FIG. 5C, a guide display 54 indicating the vertical direction is displayed. When the contact point 33a moves by the movement distance L due to the movement of the touch operation, the control point 52b also moves by the distance L. That is, the gain value is changed by a normal operation with the first resolution. Here, in the example of FIG. 5C, the touch operation is moved diagonally downward to the right, but the CPU 1 extracts only the downward component from the operation amount corresponding to the movement of the touch operation. Yes.

  Further, for example, as shown in FIG. 5D, when the control point 52b is selected by the touch operation of two fingers (contact points 53b and 53c), the resolution is determined as the second resolution. When the center of gravity 55 of the contact points 53b and 53c moves by the movement distance L by the downward movement of the touch operation, the control point 52b moves by the distance L / 2. That is, the gain value is changed by a fine operation with the second resolution. Here, also in the example of FIG. 5E, the touch operation is moved diagonally downward to the right, but the CPU 1 extracts only the downward component from the operation amount corresponding to the movement of the touch operation. ing.

  As described above, even in the operation of the virtual operation object 51 (characteristic curve) of the parametric equalizer, the operation amount of the touch operation is changed to the amount of change in the parameter value by a simple and easy way of using only the number of fingers performing the touch operation. Since the resolution for converting to ## EQU2 ## can be changed, the control of the parameter value using the virtual operation object 51 can be easily and easily understood. Further, in the case of the virtual operation object 51 (characteristic curve) in FIG. 5, the operation form is determined according to the operation for selecting one of the plurality of control points 52 (the touch operation detected in S10) ( The resolution is determined according to the operation to be selected (S13, S14).

  FIGS. 7A to 7G show examples of compressor operation screens displayed on the screen 70 of the touch panel 3 as examples of virtual operation objects according to still another embodiment. The compressor is a kind of effect imparting processing module, and has an effect of compressing the volume difference of the acoustic signal. The effect of the compressor is determined, for example, by a combination of three types of parameters: ratio, threshold level, and attack time. The virtual operation object 71 is composed of one image representing the knob part. The virtual operation object 71 is associated with three types of parameters: ratio, threshold, and attack. In addition, on the left side of the virtual operation object 31, a graph 72 indicating the characteristics of the compressor is displayed. The horizontal axis of the graph 72 indicates the ratio, and the vertical axis indicates the threshold level.

  In step S10 to S14, the CPU 1 determines the number of fingers that have performed the touch operation. When the number of fingers that have performed the touch operation is one, the operation amount of the virtual operation object 71 is changed to the parameter value. The resolution for conversion into a quantity is determined as the first resolution, and in the case of two, the resolution is determined as the second resolution. In addition, the CPU 1 determines the parameter type to be adjusted of the virtual operation object 71 according to the initial movement direction of the touch operation in steps S15 to S16.

  For example, when the touch operation is moved downward with one finger (one contact point 73a), the threshold value is changed and the virtual operation object 71 is moved downward by the normal operation based on the first resolution. Moved. In FIG. 7, the contact point before movement is indicated by a dotted line. On the other hand, when the touch operation is moved downward with two fingers (two contact points 73b and 73c), the threshold value is changed by the fine operation based on the second resolution as shown in FIG. 7C. At the same time, the virtual operation object 71 is moved downward. As the threshold value changes, the shape of the characteristic graph 72 also changes. 7B and 7C, a vertical guide display 74 is displayed.

  For example, when the touch operation is rotated with one finger (one contact point 73a), the ratio value is changed by the normal operation based on the first resolution as shown in FIG. 7D. At the same time, the virtual operation object 71 is rotated. The rotational position can be visually recognized by the mark 75. On the other hand, when the touch operation is moved downward with two fingers (two contact points 73b and 73c), as shown in FIG. 7E, the ratio value is obtained by the fine operation based on the second resolution. And the virtual operation object 71 is rotated. Further, the shape of the characteristic graph 72 also changes according to the change in the ratio value. 7D and 7E, a guide display 76 in the rotation direction is displayed.

  For example, when the touch operation is moved in the right direction with one finger (one contact point 73a), the attack time value is changed by the normal operation based on the first resolution as shown in FIG. 7F. At the same time, the virtual operation object 71 is moved rightward. On the other hand, when the touch operation is moved downward with two fingers (two contact points 73b and 73c), as shown in FIG. 7G, the attack time is reduced by the fine operation based on the second resolution. While the value is changed, the virtual operation object 71 is moved rightward. 7 (f) and 7 (g), a left and right guide display 77 is displayed.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the technical idea described in the claims and the specification and drawings. Deformation is possible. For example, the virtual operation objects 31, 51 and 71 may have any shape. Further, for example, the operation amount detected according to the movement of the touch operation is not limited to the movement direction and the movement distance, but any physical amount such as a movement speed, a movement time, or a contact pressure of the touch operation, or those It can be any combination of various physical quantities.

  Moreover, in said step S3-S5 and S12-S14 which concern on another embodiment, the number of the fingers determined may be any number, for example, two or three. Further, in steps S3 to S5 and S12 to S14 according to another embodiment, the number of two or more types of fingers may be determined, and the two or more types of resolutions may be used properly.

  Further, the plurality of types of resolutions are not limited to the first resolution for performing the “normal operation” and the second resolution for performing the “fine operation”. Various types of resolution may be included, such as resolution for converting to a large change amount.

  In another embodiment, the steps S2 and S11 may be configured to determine a moving direction of the touch operation, and the steps S3 and S12 may be configured to determine a resolution according to the determined moving direction. . In another embodiment, the steps S2 and S11 may be configured to detect a moving speed of a touch operation, and the steps S3 and S12 may be configured to determine a resolution according to the detected moving speed. . In another embodiment, the steps S2 and S11 may be configured to detect a pressure of a touch operation, and the steps S3 and S12 may be configured to determine a resolution according to the detected pressure.

  In another embodiment, when detecting the movement of touch operations of a plurality of fingers in step S6 and the like, the CPU 1 is not limited to detecting the movement of the center of gravity of the plurality of fingers, and any one of the plurality of fingers. One movement may be detected.

  In another embodiment, the step S7 further determines a change of the touch operation form (change of the number of fingers), and when the change is made, the process returns to the S3. Good. In this case, the user can change (re-determine) the resolution without releasing all touch points from the touch panel 3 and performing a new touch operation.

  In another embodiment, the steps S7 and S21 branch to Yes when any one contact point leaves the touch panel 3, and the parameter editing process is terminated (the steps S8 and S22). It may be configured.

  In another embodiment, the device for inputting an operation related to the virtual operation object 31 may be a motion capture device configured to detect the movement of the user's hand. Specific methods for detecting hand movement include detecting movement by irradiating the hand with infrared rays, etc., and detecting movement by attaching a device that can detect acceleration to the body including the hand.
