  In FIG. 1, reference numeral 101 denotes an operation area / display area of the navigation device.

Reference numerals 105, 106, and 107 denote areas obtained by dividing the operation area 101 into three areas. Reference numerals 102, 103, and 104 denote display areas that are displayed when the operation point 108 on the operation area 107, the operation point 109 on the operation area 106, and the operation point 110 on the operation area 105 are operated. Here, the operation in the present invention means that the user points a desired point on the map displayed on the display device 302 via the operation input device 303 in order to change the display position of the map, The operation point is a point designated by the user by the operation.

  For example, it is assumed that a map is displayed on the display device 201 of the navigation device as shown in FIG. In a navigation device equipped with a touch panel, when the user operates point O by touch operation, a map centered on point O is displayed on the display device 202. That is, touching a point O on the display device 201 is an operation, and the point O at this time is called an operation point.

  The operation area 101 and the display area 103 display a map with the same scale, but the display area 102 displays a map with a larger scale than the operation area 101. In the display area 104, a map having a smaller scale than the operation area 101 is displayed.

  The operation points 108, 109, and 110 correspond to the operation points on the operation areas 107, 106, and 105, respectively. Since the operation area 105 is a part of the operation area away from the center of the operation area 101, it is determined that the display movement distance expected by the user is long, and is determined as an operation target area for automatically reducing the map scale. Since the operation area 107 is an operation area close to the center of the operation area 101, the display movement distance expected by the user is not long, and it is determined that more detailed display of map information is expected, and the map scale is automatically set. Judged as the target area of the operation to be enlarged. The operation area 106 is determined as an operation area that is neither the operation area 105 nor 107, and is determined as an operation target area that does not change the scale of the map.

  In FIG. 3, reference numeral 302 denotes a display device of a navigation device, which displays a map. Reference numeral 303 denotes an operation input device that acquires an operation position using a touch panel or a pointing device.

A CPU 304 performs various calculations and controls in the present invention. Reference numeral 305 denotes a RAM in which data is input / output by the CPU 304 and temporary data is stored. Reference numeral 306 denotes a rewritable nonvolatile memory for storing a threshold value used in the present invention, and the memory is held even when the navigation main body is not turned on.

  In FIG. 4, 401 is an operation area in which the operation area 101 is defined in more detail for the present embodiment. The operation area 401 is divided into four areas, upper left, upper right, lower left, and lower right, by axes 403 and 404 orthogonal to each other at the center 402. Operation areas 405, 406, 407, and 408 are defined on the respective areas as operation areas for operations to reduce the scale. Operation areas 409, 410, 411, and 412 are defined as operation areas for operations that do not change the scale, and operation areas 413, 414, 415, and 416 are defined as operation areas for operations that increase the scale. That is, the operation area 401 is divided into 12 areas in total. The operation when each area is operated will be described later.

  The boundaries between the operation areas 405, 406, 407, 408 and the operation areas 409, 410, 411, 412 are determined by a distance 417 from the center 402, and the distance 417 is stored in advance in the nonvolatile memory 306 as a threshold A. . The boundaries between the operation areas 409, 410, 411, 412 and the operation areas 413, 414, 415, 416 are determined by a distance 418 from the center 402, and the distance 418 is stored in advance in the nonvolatile memory 306 as a threshold value B.

  Reference numeral 419 denotes an example of the operated operation point on the operation area 401, and the position is specified by an angle 421 between the distance 420 from the center 402 and the axis 403.

  FIG. 6 is a processing flow of the operation area calculation unit 506 and the map scale calculation unit 507 processed by the CPU 304.

The latitude / longitude of the operation point 419 is calculated from the information in the operation input device 303 and the map storage device 301. (Step 601)
In this embodiment, relative coordinates are used in which the latitude and longitude of the operation point 419 are (Tx, Ty) and the center 402 is (0, 0).

Rが0°以上９０°未満の場合は右下の領域、９０°以上１８０°未満の場合は左下の領域、１８０°以上２７０°未満の場合は左上の領域、２７０°以上３６０°未満の場合は右上の領域と判断する。 An angle R that satisfies the following formula is calculated. (Step 602)

(Formula 1)

When R is 0 ° or more and less than 90 °, lower right region, when it is 90 ° or more and less than 180 °, lower left region, when it is 180 ° or more and less than 270 °, upper left region, and when it is 270 ° or more and less than 360 ° Is determined to be the upper right region.

閾値Aと距離Dとの比較を行う。（ステップ６０４）
距離Dが閾値A以下の場合は、閾値Bと距離Dとの比較を行う。（ステップ６０５）
６０２により算出された領域のエリア方向（右上、左上、左下、右下）並びに閾値A及び閾値Bと距離Dとの大小関係により、１２個の操作エリアのどのエリアが操作されたかを判断することができる。 A distance D that satisfies the following formula is calculated. (Step 603)

(Formula 2)

The threshold A and the distance D are compared. (Step 604)
When the distance D is less than or equal to the threshold A, the threshold B and the distance D are compared. (Step 605)
Judge which area of the 12 operation areas has been operated based on the area direction (upper right, upper left, lower left, lower right) of the area calculated in 602 and the magnitude relationship between threshold A and threshold B and distance D. Can do.

  For example, in FIG. 4, since the distance D between the operation point 419 and the center 402 is longer than the threshold value A, step 606 is executed. That is, when the operation areas 405, 406, 407, and 408 are operated, step 606 is executed.

  When the distance D is shorter than the threshold A and the threshold B, that is, when the operation areas 413, 414, 415, and 416 are operated, Step 607 is executed.

  Furthermore, when the distance D is shorter than the threshold value A and longer than the threshold value B, that is, when the operation areas 409, 410, 411, and 412 are operated, step 608 is executed.

  In step 606, it is determined that the operation area for reducing the scale of the map to be displayed next has been operated, and the operation area information operated this time is stored in the operation history storage unit 504. In step 607, it is determined that an operation area for increasing the scale of the map has been operated. In step 608, it is determined that an operation area that does not change the scale of the map has been operated, and the operation area information operated this time in the operation history storage unit 504. Is saved.

  Here, the operation area information also stores past operation history in a table format as shown in FIG. The operation history stores information that can uniquely identify which operation area of the 12 operation areas is operated.

  In FIG. 10, operation areas 405 to 416 are associated with labels 405 to 416 having the same name, and label information is stored to uniquely identify the operation area. 1001 stores the history of the latest operation area operated this time, and 1002, 1003, and 1004 store operation areas that were operated once, twice, and three times before. The operation area of the oldest operation is saved. The number of times of saving is appropriately set for each navigation device depending on the size of the RAM and the like. Since the latest operation area in this embodiment is the operation area 408, the operation area 408 is stored in 1001.

  In step 609, it is determined whether the operation area operated this time is the same as the previous operation area.

  In FIG. 10, the current operation area is 408, but since this is different from the previous operation area 412, step 612 is executed to change the display area without changing the scale of the map. If the previous operation area and the current operation area are the same, the process for moving the display area is considered to be continuing, but if it is different, there is a high possibility that the area near the area that you want to display is displayed. By not changing the scale of the user more than necessary, the effect of suppressing the confusion of the user can be obtained.

  If the current operation is the first operation, it is determined that there is no history to compare and are not the same, and step 612 is executed.

The threshold C stored in the continuous operation threshold storage unit 505 is compared with the number of times the same area has been operated continuously up to the current operation history 1001. (Step 610)
A step of determining whether the operation area of the operation history 1001 is an operation area for enlarging or reducing a map scale when the threshold C is 3 times, and 1001, 1002, and 1003 are continuously operated in the same operation area 611 is executed. When the area that the user wants to display as the center is on the operation areas 405, 406, 407, and 408, if the scale of the map is changed by one operation, the user may be confused. Therefore, an effect that the map is not reduced more than necessary can be obtained. It is possible to change the setting according to the user's preference. When the threshold C is once, it can be determined that the setting is to change the scale of the map by one operation.

  The scale of the map is usually a stepwise scale as shown in FIG. In step 611, one of the scales 1101 to 1106 stored in the map scale storage unit 502 is changed to a map with a large one-step scale or a map with a small one-step scale. The scale stage shown in FIG. 11 is an example, and is appropriately set by an actual system.

  According to the operation area including the operation point operated by the user by the above process and according to the history of the operation area, the map information whose map scale has been appropriately changed is displayed in the display area. Therefore, it is possible to provide information effective for the user without performing an operation of changing the scale of the map. In addition, by using latitude and longitude information, the distances on the actual map such as meters and kilometers can be used as the thresholds A and B, and it is possible to set a flexible threshold that is easy for the user to understand. .

  This embodiment is a navigation apparatus that provides a method for calculating an operation area different from that of the first embodiment. The configuration block diagram of this embodiment is the same as that of the first embodiment, and FIG. 3 is used.

  7, operation areas 405, 406, 407, and 408 are operation areas for operations for reducing the map scale, and operation areas 409, 410, 411, and 412 are operation areas for operations that do not change the map scale. Yes, the operation areas 413, 414, 415, and 416 are operation areas for operations to increase the map scale.

  In the first embodiment, the boundary of the operation area and the coordinates of the operation point are calculated based on the latitude and longitude from the map information. However, in this embodiment, only the coordinates on the operation input device are used without using the latitude and longitude. By using, it is possible to obtain the effects of simplification of the functional block and simplification of the calculation amount in the processing flow. The vertical boundaries between the operation areas 405, 406, 407, and 408 and the operation areas 409, 410, 411, and 412 are determined by the distance 703 from the axis 403, and the horizontal boundaries are determined by the distance 701 from the axis 404. The distances 701 and 703 are stored in advance in the nonvolatile memory 306 as threshold values Ax and Ay, respectively. The vertical boundaries between the operation areas 409, 410, 411, 412 and the operation areas 413, 414, 415, 416 are determined by the distance 704 from the axis 403, and the horizontal boundaries are determined by the distance 702 from the axis 404. , 702 and 704 are stored in advance in the nonvolatile memory 306 as threshold values Bx and By, respectively.

  The coordinates (Tx, Ty) of the operation point 419 in FIG. 7 are expressed by relative coordinates with the coordinates of the center 402 being (0, 0), the distance 706 from the axis 403 is Ty, and the distance 705 from the axis 404 is Represented by Tx. The coordinates of the touch panel are often based on the upper left or lower left of the display area 401 as a reference (0, 0), and the coordinates of the center 402 may not be (0, 0). In this case, the coordinates (Tx, Ty) based on the coordinates of the center 402 can be calculated by taking the difference between the coordinates acquired from the operation input device 303 and the coordinates of the center 402.

  In FIG. 8, since the latitude / longitude information of the map is not used in this embodiment, the map storage device 301, the map scale storage unit 502, and the display center storage unit 503 are not required, and the configuration can be simplified.

  In this embodiment, since the operation area calculation unit 801 is different from that of the first embodiment, the changes will be described using the processing flow of FIG.

In this embodiment, the operation coordinates from the operation input device 303 are calculated using coordinates based on the center 402 instead of the latitude and longitude. (Step 901)
The area direction (upper right, upper left, lower left, lower right) of the operation area is calculated from the coordinates of the operation point according to the condition of Equation 3. (Step 902)

(Formula 3)
If Tx ≧ 0 and Ty ≧ 0, upper right area
Upper left region if Tx <0 and Ty ≧ 0
Lower left area if Tx <0 and Ty <0
Lower right area if Tx ≧ 0 and Ty <0

Next, a comparison is made as to whether the sizes of Tx and Ty exceed the sizes of Ax and Ay, respectively. (Step 903)
If either of them is exceeded, it is determined that the operation areas 405, 406, 407, and 408 have been operated.

If neither exceeds in step 903, a comparison is made as to whether the sizes of Tx and Ty do not exceed the sizes of Bx and By, respectively. (Step 904)
If neither exceeds, it is determined that the operation areas 413, 414, 415, and 416 have been operated, and it is determined that the operation is an operation area for increasing the map scale.

  Furthermore, if either of them exceeds step 904, it is determined that the operation areas 409, 410, 411, and 412 have been operated, and therefore it is determined that the operation is an operation area that does not change the map scale. Steps 606 to 612 are processed in the same manner as in the first embodiment.

  Compared with the first embodiment, the processing described above has fewer constituent blocks that do not require the map storage device 301, the map scale storage unit 502, and the display center storage unit 503 by not using latitude and longitude in this embodiment. In addition, it is possible to appropriately determine the scale of the map and provide the map information by determining the operation area with a small amount of calculation by size comparison without using the integration, the commercial calculation, and the √ operation.
