Description

Apparatus and method for controlling a vehicle display device {METHOD AND APPARATUS FOR CONTROLLING IN-VEHICLE DISPLAY DEVICE}

The present invention relates to an apparatus and method for controlling a vehicle display apparatus, and more particularly, to a touch pad capable of interworking with the vehicle display apparatus and a method and apparatus for controlling the vehicle display apparatus through the touch pad.

People's interest in vehicles goes beyond simple means of transportation, and what they can do in time and space. However, the user interface (eg, keypad, screen, etc.) that can be provided by the vehicle is spatially limited, and adding a complex user interface in the vehicle may impair the driving safety of the driver or passengers.

An input/output device as a user interface capable of more conveniently controlling an electronic device in a vehicle while driving is being used. For example, an act such as inputting a value or selecting a menu in a manner in which the driver directly touches the touch screen using a finger or the like while driving may impair driving safety. To overcome this, a control method in which a driver moves a cursor displayed on a screen of a display device using a dial manipulation mechanism and selects a menu positioned at the cursor position using a button is used. For example, if the driver turns the dial while driving, it clicks at a certain angle, and the menu may move one space on the screen for each click. Such manipulation can be fast and accurate, and the driver can comfortably control the screen without compromising driving safety. However, the screen operation using the dial is only possible with one-dimensional movement up and down or left and right (i.e., movement of the cursor along one axis within the screen), so that the driver or user can select the menu only by one-dimensional movement of the menu on the screen. There may be a disadvantage in that you have to simply configure it to do so.

Hereinafter, an apparatus and various methods to which embodiments of the present invention are applied will be described in more detail with reference to the drawings. The suffixes "module" and "part" for components used in the following description are given or mixed in consideration of only the ease of writing the specification, and do not have distinct meanings or roles by themselves.

In the description of the embodiment, in the case where it is described as being formed on "up (above) or under (below)" of each component, the upper (upper) or lower (lower) means that the two components are in direct contact with each other or One or more other components are all formed by being disposed between two components. In addition, when expressed as "upper (upper) or lower (lower)", the meaning of not only an upper direction but also a lower direction based on one component may be included.

In addition, in describing the components of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only for distinguishing the elements from other elements, and the essence, order, or order of the elements are not limited by the terms. When it is described that a component is “connected”, “coupled” or “connected” to another component, the component may be directly connected or connected to the other component, but another component is between each component. It should be understood that elements may also be “connected,” “coupled,” or “connected.”

The vehicle display device mounted on the vehicle may be disposed on a head unit in the front of the vehicle. The screen of the vehicle display device for displaying information requested by the driver and passengers is gradually increasing, and even if it is disposed in the vehicle, the driver's view should not be obscured. In addition, the screen of the vehicle display device may be implemented as a touch screen so that the driver and the person in the passenger seat can easily control it. However, in order for the driver to directly input a touch input to the touch screen using a finger or the like while driving, the driver must gaze at the screen while driving and extend his or her hand toward the touch screen. This behavior of the driver while driving can affect driving safety. In addition, when a driver or a passenger has no choice but to move continuously or intermittently in a narrow vehicle interior space, the convenience of the driver or passenger may be reduced.

In order to overcome these disadvantages and increase convenience, a method of moving the cursor using a dial as well as a touch method using a finger or the like is applied to move and select movements of the cursor on the screen of the vehicle display device. is becoming If the driver rotates the steering wheel of the vehicle or the dial placed on the seat next to the driver's seat left/right while driving, the cursor can be moved in the down/up or left/right directions. This dial method can reduce the movement of the driver while driving in controlling the display device for a vehicle, thereby promoting driving safety. However, the dial can only move the cursor on the screen in the down/up or left/right directions (one-dimensional movement), so the configuration of the screen, menu, and buttons displayed on the vehicle display device is converted into one-dimensional movement. You need to configure it to be able to control it. If the screen configuration or menu configuration is somewhat complicated, input through a one-dimensional movement using the dial may take a very long time, which may actually impair the driving safety of a driving driver.

In order to overcome the disadvantages of the dial method, a structure in which the dial is pushed up, down, left and right for free two-dimensional movement including up/down/left/right directions using the dial may be added. However, it may not be efficient to support only the two-dimensional cursor movement compared to the complexity of implementation of the configuration for moving the dial.

In order to shorten the input time by allowing the cursor to move more freely on the screen of the vehicle display device, a touch pad may be used. On the other hand, the touchpad can input handwriting and move the cursor freely in two dimensions, but since the cursor moves continuously, it may be difficult to move quickly and accurately when selecting a menu. For example, if you move your finger on the touchpad, the cursor on the display may move in the same direction and size as the moved direction. If the cursor on the screen does not jump between menus, the user may have to lengthen the touchpad operation by the amount the cursor moves. In order to overcome this disadvantage, the control device, which may be positioned between the touchpad and the vehicle display device, multiplies the movement amount of the movement input through the touchpad by a preset gain and moves the cursor on the screen of the vehicle display device. can increase However, the method of increasing the movement amount of the cursor by multiplying the gain may cause inconvenience to a driver or a user in precisely manipulating the cursor.

1 illustrates a touch input device and a vehicle display device.

As illustrated, the touch input device 12 and the vehicle display device 16 may recognize each other through a wired/wireless data communication method. The touch input device 12 may transmit a motion or signal for controlling the screen of the vehicle display device 16 .

When a driver's or user's touch movement 14 is sensed on the touch pad of the touch input device 12 , a cursor movement 18 on the screen of the vehicle display device 16 in response to the touch movement 14 . ) may occur. Here, the touch input device 12 is a device including a touch pad capable of receiving a touch input.

According to an embodiment, a portable terminal such as a smart phone, a portable computing device such as a tablet, or a notebook computer may be used as the touch input device 12 . With the development of a connected car or vehicle connectivity technology, a portable terminal or portable computing device may share a screen when connected to the vehicle display device 16, so that the portable terminal or portable computing device may be connected. The device may control the vehicle display device. However, such a screen sharing technology may require very fast data transmission and reception between a portable terminal, a portable computing device, or a vehicle display device, and may require more memory for screen configuration and input/output. Unlike the screen sharing method that is complicated and requires or consumes a lot of resources, in the embodiment of the present invention, even if the portable terminal and the portable computing device are linked and interlocked with the vehicle display device 16, a small amount for transferring the movement of the cursor It is possible to control the screen of the vehicle display device 16 only by transmitting the data.

The touch input device 12 may include a plurality of first setting lines 34 and second setting lines 32 . Here, the plurality of first setting lines 34 and the plurality of second setting lines 32 may be virtual lines that can be adjusted according to embodiments, not the concept of physical lines displayed on the touch pad. The touch pad of the touch input device 12 may operate by a pressure reduction method, a capacitive method, an infrared method, an ultrasonic method, or the like. The touch pad has a structure in which a plurality of unit elements are arranged in a matrix, and by detecting a phenomenon such as a change in pressure or a change in capacitance on a unit element at a position where the user's touch input is located, the user's It can be recognized that there is a touch input. The plurality of first setting lines 34 and the plurality of second setting lines 32 of the touch pad may be determined by being arranged on a specific line among a plurality of unit elements arranged in a matrix form. Here, the plurality of first setting lines 34 and the plurality of second setting lines 32 may be adjusted or changed according to embodiments. Also, according to an embodiment, the plurality of first setting lines 34 and the plurality of second setting lines 32 may be disposed in a direction orthogonal to each other in a horizontal direction or a diagonal direction of the touch pad.

A general touch pad recognizes the coordinates from the unit element at the location where the user's touch movement 14 occurs, updates the coordinate values according to the touch movement 14, and uses the corresponding coordinate values for the cursor in the vehicle display device 16 can induce a movement (18) of However, as described above, inducing the movement 18 of the cursor by multiplying the preset gain may cause inconvenience to the driver or the user in precisely manipulating the cursor. Accordingly, in one embodiment of the present invention, the touchpad does not output a coordinate value according to the user's touch movement 14 , and the user's touch movement 14 is a plurality of first setting lines 34 and a plurality of second By detecting which one of the setting lines 32 has passed, it is possible to transmit which setting line has passed.

2 illustrates a first example of a method for controlling a display device for a vehicle.

As shown, the first example of the control method of the vehicle display device includes the step of interlocking the vehicle display device with a touch pad including a plurality of first setting lines and a plurality of second setting lines ( 70 ), and a first on the touch pad. Determining the touch point as the origin position (72), determining the second touch point occurring after the first touch point as the movement position (74), during the touch movement from the origin position to the movement position, the first setting line or the first Step 76 of transmitting the first signal or the second signal whenever the second setting line passes, and moving the cursor on the screen of the vehicle display device in the first direction or the second direction in response to the first signal or the second signal It may include a step 78 of moving by a preset distance. Here, the first signal is a signal that can be transmitted whenever it passes through the first setting line, and the second signal is a signal that can be transmitted whenever it passes through the second setting line.

Also, the cursor on the screen may move in a first direction in response to the first signal, and the cursor on the screen may move in a second direction in response to the second signal. For example, referring to FIG. 1 , a plurality of first setting lines 34 are arranged in parallel in the vertical direction of the touch pad, and are displayed on the screen according to a first signal generated whenever the first setting lines pass through. The direction in which the cursor moves may be a horizontal (horizontal) direction of the screen. Conversely, the plurality of second setting lines 32 are arranged in parallel in the horizontal direction of the touch pad, and the direction in which the cursor moves on the screen according to the second signal generated every time it passes the second setting line is the direction of the screen. It may be in a vertical (vertical) direction.

According to an embodiment, the first distance between the first setting lines and the second distance between the second setting lines in the touch pad may be the same. This can increase convenience in controlling the on-screen cursor when the on-screen cursor moves in proportion to the same horizontal/vertical and horizontal/vertical movement distances on the plane while the driver or user uses the touch pad. because there is That is, even if the first distance and the second distance on the touch pad are the same, the cursor in the screen of the vehicle display device may move by the same amount of the preset distance in the horizontal/vertical and horizontal/vertical directions, but the preset distance It can move proportionally.

In addition, according to an embodiment, the first distance between the first setting lines and the second distance between the second setting lines in the touch pad are the size of the touch pad, the screen size of the vehicle display device controlled through the touch pad, or the touch pad. It may be determined by the ratio of the size of the screen to the screen size. For example, a preset distance in the first direction or the second direction in relation to the movement of the cursor may be different from the first distance or the second distance.

In addition, the plurality of first setting lines and the plurality of second setting lines are virtual lines that can be changed, and the distance between the first and second settings may also be changed or adjusted. For example, the number of the plurality of first setting lines and the plurality of second setting lines of the touch pad, and the distance between the first and the second distance, etc. are can be adjusted. If there are two large buttons on the screen of the vehicle display device and 10 or tens of buttons (eg, keyboard input), the number of the plurality of first setting lines and the plurality of second setting lines and the first When the distance between the distance and the second distance are adjusted, the input desired by the driver or the user can be performed more quickly and accurately.

Meanwhile, the plurality of first setting lines and the plurality of second setting lines may cross at right angles, and the first direction and the second direction may be perpendicular to each other. Also, the first direction may be determined corresponding to the arrangement direction of the plurality of first setting lines. In general, since the shape of the screen and the touch pad of the vehicle display device is a rectangular shape, when the plurality of first setting lines and the plurality of second setting lines intersect at right angles, it is intuitive to move the cursor in the process of input by the driver or the user. (Intuitiveness) can be larger. However, when the shapes of the screen and the touch pad of the vehicle display device are circular or polygonal, the plurality of first setting lines and the plurality of second setting lines may be disposed to correspond to the shapes.

According to an embodiment, in order to move the cursor on the screen of the vehicle display device, the user's touch may be continued between the first touch point (eg, the starting point) and the second touch point (eg, the target point) on the touch pad. . Also, even if the user's touch does not continue between the first touch point and the second touch point, it may be assumed that the second touch point is input within a preset time from the time of the first touch point. In addition, when the first touch point and the second touch point are within a preset range, it may be determined that the cursor location is selected on the screen by touching the same location twice.

The coordinates of the location input by the user on the touchpad are not the same as the location (coordinates) of the cursor on the screen of the vehicle display device. If the first touch point input by the user is the current location (position before movement) of the cursor on the screen and the user generates a touch movement from the first touch point to the second touch point, the cursor on the screen corresponds to the touch movement. moves from the current position (position before movement) to the next position (position after movement).

Meanwhile, although not shown, in the first example of the control method of the vehicle display apparatus, when the touch movement from the origin position to the movement position does not coincide with the horizontal/vertical or horizontal/vertical directions on the touch pad and is inclined, touch movement The method may further include correcting the inclination of . When the driver or user tries to move the cursor on the screen through the touch pad, even though the actual desired direction is in the horizontal direction, the actual touch movement on the touch pad may include a vertical motion component rather than only a horizontal motion component. . For example, when a driver or user inputs a touch movement on a touch pad, it may be difficult to input such as a straight straight line. Accordingly, the position, spacing, and arrangement of the first setting line or the second setting line in response to unnecessary input components depending on whether the driver or user's touch movement wants horizontal, vertical, or horizontal/vertical movement can be adjusted. It is assumed that the driver or the user repeatedly repeats the horizontal movement several times and inputs it through the touchpad. In this case, a slight vertical movement may be included in each horizontal movement, and the vertical movement may be combined in a process that is repeated several times, so that the cursor on the screen may move in the vertical direction even though the driver or the user did not want it. Accordingly, when the movement in a specific direction among the touch movements input by the user does not exceed a preset reference range, the movement in the corresponding direction is determined as not desired by the user, and the corresponding movement may be offset through correction.

Specifically, in order to correct the inclination of the touch movement, the first example shows that when the touch movement passes the first setting line, the middle between the passing position of the first setting line and the two second setting lines closest to the passing position is The second interval can be calculated. If the first interval does not exceed the preset reference range, the arrangement of the plurality of second setting lines may be adjusted by the second interval.

Similarly, in order to correct the inclination of the touch movement, when the touch movement passes through the second setting line, the first setting point is between the passing position of the second setting line and the middle between the two first setting lines closest to the passing position. interval can be calculated. If the first interval does not exceed the preset reference range, the arrangement of the plurality of first setting lines may be adjusted by the first interval.

Although not shown, the first example of the control method of the vehicle display apparatus may further include generating vibration in response to the first signal or the second signal. In this case, depending on the embodiment, the vibration corresponding to the first signal and the vibration corresponding to the second signal may be different from each other.

3 illustrates a second example of a method for controlling a display device for a vehicle.

As shown, the second example of the method for controlling the vehicle display device includes the step of interlocking the vehicle display device with a touch pad including a plurality of setting spaces ( 60 ), and a setting space in which the first touch point on the touch pad is located. determining as the origin position (62), determining the setting space in which the second touch point generated after the first touch point is located as the movement position (64), between the setting space during the touch movement from the origin position to the movement position The method may include transmitting a movement signal including a direction value whenever moving (66), and moving a cursor on the screen of the vehicle display device by a preset distance in response to the movement signal (68).

The touch pad may include a plurality of virtual first setting lines and a plurality of second setting lines, but may include a plurality of virtual setting spaces according to an exemplary embodiment. Here, the setting space is a virtual region in which a plurality of touch pads are divided, and may be arranged in a matrix form, or may be determined in various shapes and shapes according to the shape of the touch pad.

4 illustrates an apparatus for controlling a display device for a vehicle.

As shown, the control device 12 for controlling the vehicle display device 16 includes a transmission unit 28 that transmits a control signal to the vehicle display device 16 through a wired/wireless data communication method, a plurality of first setting lines, and The touch input unit 22 including a plurality of second setting lines and receiving a user's touch input, and a first touch point on the touch input unit 22 are determined as the origin position, and the first touch point in the touch input unit 22 The second touch point generated later is determined as the moving position, and a control unit 24 that generates a control signal whenever the first setting line or the second setting line passes during the touch movement from the origin position to the moving position. there is.

The first distance between the first setting lines in the touch input unit 22 and the second distance between the second setting lines are the same, and the first distance and the second distance may be changed or adjusted. In addition, the plurality of first setting lines and the plurality of second setting lines in the touch input unit 22 intersect at right angles, and the control signal may include information in a first direction or a second direction perpendicular to each other.

The plurality of first setting lines in the touch input unit 22 may be arranged in a horizontal or diagonal direction of the touch input unit 22 , and the first direction or the second direction may be determined corresponding to the arrangement direction of the plurality of first setting lines. .

Meanwhile, the first touch point and the second touch point transmitted through the touch input unit 22 may be determined differently according to embodiments. For example, only when the user's touch movement continues, the start and end of the touch movement may be determined as the first touch point and the second touch point. However, according to an embodiment, even if the user's touch does not continue between the first touch point and the second touch point, it may be determined that the second touch point is input within a preset time from the time of the first touch point. Meanwhile, when the first touch point and the second touch point transmitted to the touch input unit 22 are within a preset range, the controller 24 may generate a selection signal for selection rather than movement.

Also, when the touch movement from the origin position to the movement position does not coincide with the horizontal/vertical or horizontal/vertical directions on the touch input unit 22 and is inclined, the controller 24 may correct the inclination of the touch movement. For example, when the touch movement passes through the first setting line, the control unit 24 calculates the second interval between the passing position of the first setting line and the middle between the two second setting lines closest to the passing position, When the first interval does not exceed the preset reference range, the arrangement of the plurality of second setting lines may be adjusted by the second interval. Similarly, when the touch movement passes through the second setting line, the control unit 24 calculates a first interval between the passing position of the second setting line and the middle between the two first setting lines closest to the passing position, When the first interval does not exceed the preset reference range, the arrangement of the plurality of first setting lines may be adjusted by the first interval.

Referring to FIG. 4 , the control device 12 of the vehicle display apparatus may further include a vibration motor 26 for generating vibration in response to a control signal output from the control unit 24 . Here, according to an embodiment, the vibration motor 26 may generate different vibrations in response to the directionality included in the control signal. The vibration generated by the vibration motor 26 may be regarded as feedback to the driver or the user as to how much cursor movement is induced by the touch movement. The driver or user can tactilely sense how much the screen cursor moves through vibration, even if it does not directly move the screen cursor.

5 illustrates a first example of movement of a cursor on a screen of a display device for a vehicle.

As shown, the touch input unit 32 includes a plurality of first setting lines 34 and a plurality of second setting lines 32 . It may be assumed that the driver or user generates a touch movement from the first touch point 42A to the second touch point 44A on the touch input unit 32 (arrow direction). The touch movement from the first touch point 42A to the second touch point 44A sequentially follows the first setting line 34 at the first point 52A, the second point 52B, and the third point 52B. can pass through Accordingly, when passing through the first point 52A, the second point 52B, and the third point 52B, a first signal indicating that it has passed the first setting line 34 is output, and corresponding to the first signal Accordingly, three sequential movements 54A, 54B, and 54C of the cursor on the screen of the vehicle display device 16 may be induced.

Here, the distance the cursor moves on the screen in response to the first signal generated when passing through the first setting line 34 may correspond to a preset value. Here, the preset value may be adjusted according to an embodiment or environment setting.

The control unit configures a virtual grid determined by the plurality of first setting lines 34 and the plurality of second setting lines 32 in the touch input unit 32 . The virtual grid may be formed through software of the control unit that processes the finger position information of the touch input unit 32, and is a plurality of lines connecting predetermined coordinates of a plurality of elements included in the touch input unit 32 vertically/left and right. It may be determined through the first setting line 34 and the plurality of second setting lines 32 . For example, if the touch input unit 32 has coordinates of 100X100, 10, 20, 30 ... Coordinates in line 90 and 10, 20, 30 … Coordinates of 90 columns may be a virtual grid in vertical/left/right directions, respectively. Whenever the user's drag passes through the virtual grid, the control unit can analyze which grid from the drag start point has crossed, move the menu in the corresponding direction, and simultaneously operate the vibration motor to inform the driver that the menu has jumped. For example, if the user drags by hand from coordinates 5, 5 to 35, 5 based on the touch element, the setting line of lines 10, 20, and 30 is passed, and the menu is 1 every time it passes the setting line of the virtual grid. It moves up 3 spaces at a time, and can vibrate 3 times at the same time.

6 illustrates a second example of movement of a cursor on a screen of a display device for a vehicle.

As shown, the user's movement on the touch input unit 32 including the plurality of first setting lines 34 and the plurality of second setting lines 32 passes the first setting line 34 twice and then The second setting line 32 is passed once and the first setting line 34 is passed once again. At this time, at points 52D, 52E, 52F, and 52G passing through the plurality of first setting lines 34 and the plurality of second setting lines 32, a signal for moving the cursor on the screen of the vehicle display device 16 is , and in response to the signal, the cursor may move sequentially (54D, 54E, 54F, 54G).

5 and 6 , when the reference coordinate for determining the virtual grid is a fixed value, when the driver or user drags with a different amount of movement depending on the initial contact position, a problem of crossing the virtual grid occurs. Thus, the driver or user can feel the heterogeneity of the operation in controlling the screen. Therefore, the virtual grid needs to readjust the initial coordinates according to the user's finger contact position. That is, the controller may determine whether the finger first touched the touchpad, set the contact coordinates as the origin coordinates of the virtual grid, and adjust the virtual grid by a difference from the existing origin coordinates. For example, the reference of the virtual grid determined by the plurality of first setting lines 34 and the plurality of second setting lines 32 is 10, 20, 30 ... Coordinates in line 90 and 10, 20, 30 … It consists of coordinates in 90 columns, and if the initial contact position is 5, 5, the coordinates of the origin may not be adjusted because it is an intermediate value in the 0, 0 ~ 10, 10 grid. On the other hand, if the initial contact position is 3, 6, the coordinates of the grid origin are adjusted by -2, 1, so that the coordinates of rows 8, 18, 28 ... 88 and the coordinates of columns 11, 21, 31 ... 91 are multiple. It may be a virtual grid composed of a first setting line 34 and a plurality of second setting lines 32 .

7 illustrates a method of correcting a user's touch input.

As shown, it is assumed that the user inputs a touch movement from the first touch point 46A to the second touch point 46B. In this case, between the first touch point 46A and the second touch point 46B, a movement component in a vertical (vertical) direction as well as a movement component in a horizontal (horizontal) direction is included.

For example, when the drag crosses the right setting line, it may be assumed that the vertical (vertical) direction drag angle is 20 degrees, and the vertical (vertical) direction reference angle TA is 30 degrees. Since the drag angle is smaller than the reference angle (TA) if the coordinates in the vertical (vertical) direction are raised by 10 from the starting point, the vertical (vertical) direction is used to offset the vertical (vertical) movement during the user's drag input. Adjust the grid up by 10.

That is, the control unit determines whether the user's drag crosses the virtual grid, calculates a drag angle in a direction perpendicular to the set line over which the drag crosses, and determines whether the angle exceeds a reference value. If it does not exceed the reference value, the grid by the set line is adjusted with the coordinates in the direction perpendicular to the grid at the moment of crossing the virtual set line as the center point. If it exceeds the standard value, the user intends to move diagonally, so the grid is not adjusted by the set line.

As described above, the correction may be determined by the angle of the input touch movement and the reference angle, and when the touch movement passes the setting line, the distance from the adjacent setting line is calculated according to which point the setting line passes, It can also be determined whether it is within a reference range. If motion in the vertical (vertical) direction by D1 is sensed but is lower than the reference, the vertical (vertical) movement by D1 may be compensated by moving the set line by the corresponding distance D1. Detecting the next movement at the second touch point 46B may be performed based on a compensated set line. Here, compensation of the setting line may be performed for every touch movement (eg, a single drag).

The user's drag direction cannot be exactly vertical/horizontal to the touchpad. The user drags to move the menu in only one direction, but in reality, a component perpendicular to the intended drag direction occurs. . However, through the above-described compensation for adjusting the virtual grid for an unwanted direction according to the drag, it is possible to prevent the menu from being moved in an unintended direction by the user.

8 illustrates a third example of a method for controlling a display device for a vehicle.

As shown, in the third example of the method of controlling the display device for a vehicle, the start ( S80 ) to the end ( S94 ) may be repeated for each drag movement and user's touch movement. First, it is detected whether the first contact has occurred (S82), and when the first contact occurs, a virtual grid composed of a plurality of first setting lines and a plurality of second setting lines can be adjusted based on the coordinates of the touch element of the contact point (S84). ). When a user's touch movement occurs, it detects inter-lattice movement (that is, has passed the set line), outputs a signal to move the cursor in the movement direction, and generates vibration through the vibration motor in response to the signal. There is (S88). On the other hand, in addition to inducing the movement of the cursor, it is possible to determine whether there is a movement component (movement that does not affect the movement of the cursor) that is judged unnecessary in the user's touch movement, and whether the reference range or reference value is exceeded. There is (S90). If the correction is not necessary, it ends (S94). If correction is required, the virtual grid composed of a plurality of first setting lines and a plurality of second setting lines may be corrected (S92), and when correction is performed, the correction is completed (S94).
