(First embodiment)
Hereinafter, an example of the configuration of the display processing apparatus according to the present embodiment will be described with reference to FIGS. The display processing apparatus according to the present embodiment is used in an in-vehicle navigation apparatus that displays a map navigation screen or the like.

  FIG. 1 is a diagram illustrating an example of an appearance of the navigation apparatus A according to the present embodiment. FIG. 2 is a diagram illustrating an example of a hardware configuration of the navigation apparatus A according to the present embodiment. FIG. 3 is a diagram illustrating an example of functional blocks of the control device 1 according to the present embodiment. FIG. 4 is a development view showing a component configuration of the display unit 3 according to the present embodiment. FIG. 5 is a cross-sectional view showing a component configuration of the display unit 3 according to the present embodiment.

  The navigation device A includes a control device 1, a storage device 2, and a display unit 3. Mainly, map image data to be displayed is generated or the map image is displayed and output by these devices.

  The control device 1 (display processing device) includes, for example, a CPU (Central Processing Unit). And the control apparatus 1 carries out data communication with each part of the navigation apparatus A, and centrally controls these operation | movement, when CPU runs a computer program.

  The control device 1 has functions of a display control unit 1a and an input information acquisition unit 1b. The display control unit 1a and the input information acquisition unit 1b are realized, for example, when the CPU executes an application program (see FIG. 3). Details of operations using these functions will be described later with reference to FIG. ).

  The display control unit 1a uses the map image data associated with the map coordinates stored in the storage device 2 to generate a map image to be displayed on the display unit 3 (display device 3a) for a user touch operation or the like. The map image to be displayed is controlled accordingly. The display control unit 1a performs such control based on the input information including the position and press of the touch operation acquired by the input information acquisition unit 1b.

  The input information acquisition unit 1 b acquires input information including the position and press of a touch operation performed on the display unit 3. A signal indicating the position when the touch operation is performed is output from the display unit 3 (touch sensor 3b) to a register included in the control device 1, for example. Then, the input information acquisition unit 1b acquires the input information related to the touched position based on the signal stored in the register. Moreover, the signal which shows the press when a touch operation is carried out is output as a voltage value from the display unit 3 (pressure sensor 3c), for example. The input information acquisition unit 1b acquires input information related to pressing in a touch operation based on the voltage value.

  When the application program operates on the system program, the input information acquisition unit 1b may be configured to acquire input information related to the position and press of the touch operation from the system program. For example, the input information acquisition unit 1b acquires the data from the system program in an event-driven manner when the system program acquires a signal indicating the position or press of the touch operation from the touch sensor 3b or the pressure sensor 3c. It is good also as composition to do.

  Here, the input information related to the position and press of the touch operation is specified based on signals output from the touch sensor 3b and the pressure sensor 3c, which will be described later. However, other methods may be used as long as the position and press of the touch operation can be specified. The input information acquisition unit 1b may specify the position of the touch operation based on, for example, the balance of pressure acquired from a plurality of pressure sensors 3c (FIG. 4) described later.

  The functions of the display control unit 1a and the input information acquisition unit 1b may be configured such that a plurality of computer programs cooperate using an API (Application Programming Interface) or the like. The display control unit 1a may be configured to cause the GPU to execute part or all of the processing on the image data using a GPU (Graphics Processing Unit) or the like.

  The storage device 2 includes, for example, a ROM, a RAM, an HDD, and the like, and stores various processing programs such as a system program, an application program executable on the system program, and various data. Form a work area for temporary storage. In addition to the HDD, the storage device 2 may be stored in an auxiliary storage device using a flash memory or the like so as to be read / write updated. These data may be sequentially downloaded through the Internet line and stored in the storage device 2 in response to a request by a vehicle position or a touch operation.

  The storage device 2 has map image data associated with map coordinates. The map image data is image data that generates an image of a road or terrain according to map coordinates. Further, the map image data includes map image data of a plurality of scale levels. For example, when displayed in the display area of the display unit 3, the map image corresponding to a topographic map of 1: 200,000 is displayed. A map image or the like corresponding to a topographic map of 1 / 255,000 when displayed in the display area 3 is included.

  The map coordinates are, for example, information on latitude and longitude, and are stored in association with a plurality of points in the map image data. Further, the map coordinates may be obtained by calculation processing on the basis of latitude and longitude information for a predetermined point in the map image data and other points as a reference.

  That is, when the user performs a touch operation on the display area of the display unit 3, the map image data is based on the position of the touch operation based on the position of the touch operation and the map coordinates of the map image currently displayed. Corresponding map coordinates can be specified.

  The display unit 3 includes a display device 3a, a touch sensor 3b, and a pressure sensor 3c (see FIGS. 4 and 5).

  The display device 3a is configured by, for example, a liquid crystal display, and displays a map image or the like in the display area of the liquid crystal display. Image data is input from the control device 1 to the display device 3a, and a map image or the like is displayed based on the image data.

  The touch sensor 3b is a user input device for the navigation device A, and detects a position where a touch operation is performed on the display area of the display device 3a. As the touch sensor 3b, for example, a projected capacitive touch sensor is used, and a plurality of capacitances are arranged in a matrix on the display area of the display device 3a by X electrodes and Y electrodes arranged in a matrix. A sensor is configured. Then, the touch sensor 3b detects a change in capacitance due to capacitive coupling generated between the electrodes and the finger when the finger approaches the touch sensor 3b. The position where the operation was performed is detected. And the said detection signal is output to the control apparatus 1 as a signal which shows the position where touch operation was made.

  The pressure-sensitive sensor 3c is a user input device for the navigation device A, and detects a pressure in a touch operation on the display area of the display device 3a. As the pressure-sensitive sensor 3c, for example, a sensor whose resistance value changes depending on the pressure of contact is used, and the change in the resistance value is converted into a voltage value to detect pressing in a touch operation. The pressure sensitive sensors 3c are arranged at four positions at positions corresponding to the four sides of the outer periphery of the display area of the display device 3a. A signal indicating the press in the touch operation detected by the pressure sensor 3 c is output to the control device 1.

  The display unit 3 includes a housing 3d, a cover lens 3e, and a double-sided tape 3f in addition to the display device 3a, the touch sensor 3b, and the pressure sensor 3c.

  Specifically, the display unit 3 includes a plate-like touch sensor 3b and a cover so that the display device 3a is accommodated in the housing 3d so that the display region is exposed, and covers the display region of the display device 3a. A lens 3e is arranged in this order. And the plate-shaped touch sensor 3b is being fixed with respect to the housing | casing 3d using the double-sided tape 3f in the outer side of the outer edge part of the display area of the said display apparatus 3a. The pressure sensor 3c is installed between the plate-like touch sensor 3b and the housing 3d on the outer periphery of the display area of the display device 3a. When the user performs a touch operation on the display unit 3, the touch operation is performed on the surface of the cover lens 3e.

  The navigation device A includes a GPS 4, a gyro sensor 5, a vehicle speed sensor 6, a TV receiver 7, a radio receiver 8, a CD / DVD playback device 9, a connection port 10 for connecting a digital audio player, and the like. Is configured to be capable of data communication with these devices. In addition, since these apparatuses are all well-known, detailed description here is abbreviate | omitted.

<Operation of navigation device>
Next, an example of the operation of the navigation device A according to the present embodiment will be described with reference to FIGS.

  FIG. 6 is a diagram illustrating an example of an operation flow of the navigation device A according to the present embodiment. This operation flow is an operation performed by the control device 1 and is realized, for example, when the control device 1 executes processing according to an application program. Below, especially the display control which concerns on the wide area display which the display control part 1a performs is demonstrated. The “wide area display” means that the scale of the area on the terrain relating to the map image currently displayed on the display unit 3 is changed, and a wide area map image including the area is displayed.

  FIG. 7 is a diagram illustrating an example of screen transition of the navigation device A according to the present embodiment. 7A to 7F show a state in which the display control unit 1a generates the image based on the image data of the map image and sequentially updates the image according to the touch operation. 7A to 7F represent the outer frames of the display area of the display unit 3, respectively. T1 represents the touch position in the display area, and T2 represents the area of the map image displayed when the operation related to the wide area display is finished.

  When executing the application program, the display control unit 1a first reads out the position data of the vehicle acquired by GPS, and from the map coordinates corresponding to the position data of the vehicle, the position of the vehicle (in the figure, A map image is generated so that (indicated by a triangular mark) is located near the center of the display area. Here, it is assumed that the map image (first map image) shown in FIG. 7A is displayed.

  In this state, the display control unit 1a waits for the user to perform a touch operation on the display unit 3 (step S1: NO). In addition, a user's touch operation is determined by monitoring the signal from the touch sensor 3b input into the control apparatus 1 by the input information acquisition part 1b, for example.

  When a touch operation is performed on the display unit 3 (step S1: YES), first, the input information acquisition unit 1b touches the touch operation in the display area of the display unit 3 based on a signal from the touch sensor 3b. The position T1 is specified (step S2). Next, the input information acquisition unit 1b acquires a signal from the pressure-sensitive sensor 3c, and specifies the pressing of the touch operation (step S3).

  The display control unit 1a determines whether or not the pressure acquired by the input information acquisition unit 1b is equal to or greater than a threshold value (step S4). And when it determines with a press being more than a threshold value (step S4: YES), the display control part 1a produces | generates the map image which made the present map image the wide display (step S5). On the other hand, when it determines with a press being less than a threshold value (step S4: NO), the display control part 1a performs subsequent step S10, S11 as normal touch operation. The display control unit 1a determines whether there is a process corresponding to the touch position T1 of the touch operation in order to execute a normal touch operation process (step S10). When there is a process corresponding to the touch position T1 of the touch operation (step S10: YES), the display control unit 1a executes the process (for example, a process of moving the map image) (step S11), and again. The process returns to the standby state in step S1. Further, when there is no process corresponding to the touch position T1 of the touch operation (step S10: NO), the display control unit 1a returns to the standby state of step S1 again.

  In the process of step S5, the display control unit 1a generates a map image in which the current map image is displayed in a wide area starting from the map coordinates corresponding to the touch position T1, and displays the map image on the display unit 3 (see FIG. 7B). reference). First, the display control unit 1a specifies map coordinates (for example, latitude and longitude) corresponding to the touch position T1 based on the touch position T1 and the data of the currently displayed map image. Then, the display control unit 1a generates a map image (second map image) in which the current map image is displayed in a wide area so that the map coordinates are fixed in the display area of the display unit 3. To do. At this time, the scale of the wide area display is, for example, the ratio of the actual distance on the terrain of the map image to the distance on the display area of the display unit 3 (hereinafter referred to as the actual distance / display distance) is 100 m / When a map image of cm is displayed, a map image having an actual distance / display distance of 400 m / cm is selected as a map image for wide area display. The display control unit 1a acquires the map image data and the map image data of the scale specified in this way from the storage device 2, and generates a wide-area map image as shown in FIG. 7B.

  7B shows that the map image of FIG. 7A is displayed in a wide area on the display unit 3 in a state where the position of “school” (sentence mark) at the touch position T1 is fixed in the display area of the display unit 3. The map image displayed is displayed. As a mode of displaying the map image starting from the map coordinate corresponding to the touch position T1, the map image is generated so that the map coordinate corresponding to the touch position T1 is fixed in the display area of the display unit 3. In addition to the mode to be performed, a mode in which a map image is generated such that the map coordinates corresponding to the touch position T1 are positioned at the center of the display area of the display unit 3 may be used.

  The display control unit 1a continues this wide-area display state until the touch operation ends. Here, the end of the touch operation is determined by the input information acquisition unit 1b monitoring a signal from the touch sensor 3b input to the control device 1. Specifically, the input information acquisition unit 1b does not perform the scroll operation based on the signal from the touch sensor 3b input to the control device 1 (step S6: NO), and in addition, the touch operation is not detected. (Step S8: YES), it is determined that the touch operation has been completed. When the touch operation is finished, the display control unit 1a generates a map image of the original scale display before the wide area display (step S9) (see FIG. 7C). Note that a rectangular area T2 surrounded by a dotted line in FIG. 7B corresponds to an area of the map image of the original scale display.

  On the other hand, when the scroll operation is performed in the state of the wide area display (step S6: YES) (see FIG. 7D), the display control unit 1a generates a map image to move in the state of the wide area display (step S6). S7) (see FIG. 7E). More specifically, the scroll operation is detected based on a temporal change in the touch position T1 in the touch operation acquired by the input information acquisition unit 1b. Then, the display control unit 1a displays the map image so that the scroll operation holds and moves the map coordinates corresponding to the touch position T1 before the scroll operation. In other words, the display control unit 1a moves the map coordinates corresponding to the touch position T1 before the scroll operation to the touch position T1a in the display area of the display unit 3 after the scroll operation.

  FIG. 7D shows a state before the image is changed when the touch position is changed from the position T1 of “school” (sentence mark) to the position T1a of “post office” (〒 mark). Yes. FIG. 7E shows a state where “school” (sentence mark) has moved to the vicinity of the touch position T1a after the scroll operation. By doing in this way, a user can be made to visually recognize as a map moved to the distance and direction corresponding to the said scroll operation by scroll operation.

  7D and 7E, the rectangular area T2 represents the area of the map image displayed when the wide area display is changed to the original scale display as described in FIG. 7B. Here, the rectangular area T2 is displayed on the map image so as to be displayed at a fixed position on the display area of the display unit 3 at all times. Accordingly, when the user performs a scroll operation in step S7 as described above in the wide-area display state, the display control unit 1a displays the map image while moving the position of the rectangular region T2. Control.

  When the scroll operation is finished and the touch operation is not detected (step S8: YES), the display control unit 1a returns the map image to the original scale display as described above (step S9) (FIG. 7F). At this time, the display control unit 1a displays a map image of the rectangular region T2 surrounded by a dotted line in FIG. 7E. In other words, the display control unit 1a specifies the map coordinates to be displayed based on the touch position when the touch operation is finished, and generates a map image in the original scale display. The rectangular area T2 is an index indicating the area of the map image displayed when the wide area display is changed to the original scale display.

  By performing the operation as described above, the display control unit 1a sequentially updates the image data of the map image and controls the display of the map image. Although not described above, the display control unit 1a may sequentially acquire vehicle position data from the GPS and move the map image of FIG. 7A or the like based on the position data. It is.

  As described above, according to the navigation device A according to the present embodiment, it is determined whether the touch operation is a normal touch operation (for example, movement of a map image) or a touch operation for wide area display based on the press of the touch operation. The user can switch the map image to the wide area display with only one touch operation without requiring operation time. Then, the user can automatically return the map image displayed in the wide area display to the original map image in the scale display as the touch operation ends. Therefore, the navigation apparatus A according to the present embodiment can realize a user interface suitable for a usage mode in which a map image is switched to wide area display and glimpsed.

  In particular, when the display control unit 1a switches the display to the map image of the wide area display, the map coordinates of the position where the user touches the map image of the wide area display is fixed on the display area of the display unit 3. To display. Therefore, the user can grasp the entire positional relationship of the map image of the wide area display earlier.

  In addition, when the user makes the wide area display, the user can move the map image of the wide area display while continuing the touch operation, and change the area of the map image to be displayed when the original scale display is restored. can do. Therefore, the navigation apparatus A according to the present embodiment can realize a user interface suitable for a usage mode such as moving to a map image of a desired area.

(Second Embodiment)
Next, a navigation apparatus A according to the second embodiment will be described with reference to FIGS.

  The navigation apparatus A according to the present embodiment is different from the first embodiment in that the scale of the wide area display can be changed in accordance with a press during a touch operation. In addition, description is abbreviate | omitted about the structure which is common in 1st Embodiment (Hereafter, it is the same also about other embodiment.).

  FIG. 8 is a diagram illustrating an example of data on the degree of scale change of the map image according to the press. In FIG. 8, the threshold value of pressing is provided in three stages a, 2a, and 3a (a is a predetermined constant), and the area corresponding to each range is twice the current display area (for example, the actual distance). / If the display distance is a map image of 100 m / cm, the actual distance / the map image of the display distance is 200 m / cm), the display area three times the current display area, the four times the current display area The display area is set to be displayed.

  Describing according to the operation flow shown in FIG. 6, in step S4, the display control unit 1a sets a plurality of threshold values when identifying the touch operation pressing, and identifies the corresponding pressing level. Specifically, the display control unit 1a identifies which level in FIG. 8 corresponds to the press specified by the input information acquisition unit 1b in step S3. Thereby, the display control part 1a can select the scale of the map image according to pressing.

  Subsequently, in step S5, the display control unit 1a specifies the map coordinates corresponding to the touch position, and generates a map image for wide-area display based on the map coordinates and the scale of the map image selected above. And display on the display unit 3.

  Thereafter, the display control unit 1a performs the processes of steps S6 to S9 and the like in the same manner as described in the first embodiment.

  As described above, according to the navigation device A according to the present embodiment, the user can switch the map image to a wide area display at a desired scale level with a simple operation. Therefore, the navigation apparatus A according to the present embodiment can realize a suitable user interface by a usage mode in which the map image is switched to the wide area display and glanced.

(Third embodiment)
Next, with reference to FIG. 9, the navigation apparatus A which concerns on 3rd Embodiment is demonstrated.

  The navigation apparatus A according to the present embodiment is different from the first embodiment in terms of screen transition when switching the display to a wide-area map image.

  FIG. 9 is a diagram illustrating an example of screen transition of the navigation device A according to the present embodiment. Here, FIGS. 9A and 9C are the same images as FIGS. 7A and 7B, respectively, and show a map image before the wide area display and a map image after switching to the wide area display.

  FIG. 9B shows an image in the middle of the screen transition when changing from the map image before the wide area display to the map image set to the wide area display. FIG. 9B shows a state in which the map image (FIG. 9C) displayed in the wide area is three-dimensionally deformed so as to be pushed toward the depth direction on the right side of the display area of the display unit 3. That is, the screen transition of FIG. 9B enables the user to intuitively understand that the display is switched to the wide area display by the touch operation.

  Then, the display control unit 1a deforms the wide-area display map image so that the wide-area display map image is pushed in the depth direction on the right side of the display area of the display unit 3, and then the wide-area display without deformation. Display control to return to the map image of.

  Display control that is pushed in by a touch operation can be performed by deforming a wide-area map image over time. Note that the three-dimensional effect as if the image was pushed in can be expressed, for example, by increasing the image density in a region in the depth direction using affine transformation.

  For example, the display control unit 1a first generates the image data of the map image of the wide area display illustrated in FIG. 9C by the same process as described in step S5 of FIG. Specifically, the display control unit 1a acquires map image data of map coordinates and scale corresponding to the position where the touch operation is performed from the storage device 2, and displays map image data of wide display as shown in FIG. 9C. Generate.

  Next, the display control unit 1a determines whether the position of the touch operation is biased in the up, down, left, or right direction from the center of the display area of the display unit 3. The display control unit 1a identifies the bias according to the position of the touch operation acquired by the input information acquisition unit 1b and the balance of the pressures of the four pressure-sensitive sensors 3c acquired by the input information acquisition unit 1b. Can do.

  Then, the display control unit 1a transforms the map image of the wide area display into the display unit 3 by deforming the map image of the wide area display so as to increase the degree of compression in the vertical direction and the horizontal direction as it goes to the right direction, for example. It is possible to perform a three-dimensional display that is inclined in the depth direction on the right side of the display area. Then, the display control unit 1a increases the compression degree in the vertical direction and the left-right direction of the map image of the wide area display over time, and then decreases the compression degree over time again to reduce the original wide area display. Return to the map image.

  By doing so, it is possible to express a state in which the map image is pushed and changed to a wide area display by a touch operation in which the pressure exceeds a threshold value. When the user touches the left corner of the display area, the display control unit 1a generates an image that is deformed so that the map image to be displayed in a wide area is pushed toward the depth direction on the left side, contrary to the above. Thus, the image is displayed on the display unit 3.

  As described above, according to the navigation device A according to the present embodiment, it is easy to intuitively grasp the switching operation to the wide area display performed by the user, and it is possible to improve the preference for the user.

  As mentioned above, although the specific example of this invention was demonstrated in detail, these are only illustrations and do not limit a claim. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.

  At least the following matters will become apparent from the description of this specification and the accompanying drawings.

The display may be switched from the first map image to the second map image so as to be displayed at the same position on the display unit. According to the display processing device 1, the user can grasp the overall positional relationship of the map image displayed in the wide area earlier.

  In addition, here, when a touch operation of pressing that is equal to or greater than the threshold is performed, the display control unit 1a determines a magnification of the wide area display according to the pressing, and the second according to the magnification of the wide area display. The display may be switched to a map image. According to the display processing device 1, the user can make a glance at a desired scale-scale wide area display of the map image with a simple operation.
