Palette (palette) image that is used for target image is to download to together the map display 20 from map distribution server 30 in advance, specify by position and numbering, can in map display 20, describe target image to each target.This technology is opened the technology of being put down in writing in the 2006-128801 communique such as being suitable for the spy.
That is, at first,, obtain the picture coordinate of icon center latitude, longitude based on map center latitude longitude, map orientation, map multiplying power (engineer's scale).Then, if target image is 16 * 16 dot matrix, so with regard in the before coordinate of obtaining, its off-set value is that 8 position begins to describe target image on the XY coordinate.This to describe to handle be only to have under the situation of target data, and each target is repeated.Therefore, when target image overlaps, after the target image described just be formed on the target image of formerly describing, it becomes the uppermost state of display frame that is displayed on.
Target display control apparatus 27 based on target data as shown in Figure 4, and is controlled based on the positional information of each target on the map image that is presented on the display device 26 and to be carried out describing each target image (icon image etc.).At this moment, under the situation in target image is overlapped in narrow zone, it is according to describing the superimposed demonstration of order.This moment, do not specify this which target image to be presented at the top of display frame yet.When carrying out cursor operations here, cursor operations checkout equipment 29 detects after the cursor position, calculates the distance between itself and each target image.
From cursor operations checkout equipment 29 receive and the position of cursor and and each target image between after the information of distance, subject object decision device 281 is subject object with the target decision nearest apart from cursor position, and target display control apparatus target image to this subject object on display device 26 redraws processing.Being presented at image on the display device 26 is displayed on uppermost, the up-to-date image represented of display frame by this and constitutes, so by this processing, in case carried out cursor operations, just can make to allow the target image of the target nearest (subject object) be presented at the top of display frame apart from cursor position.
Therefore, the user of map display 20 observes the map image that is presented on the display device 26, is presented at the target image on the map image, the operation cursor is presented at the top of picture until desired target image, just can the desired target of reliable recognition, and it is selected.The calculating of distance is that on behalf of the mode of distance between the position, each carry out by obtaining them between cursor position and each target location.Here, represent the position such as can being that the words of tracking cross are the centre coordinate of cross (center), are exactly the coordinate of pointing front end under the situation of arrow mark, and be not limited to above-mentioned form, can also be to be the coordinate in the image place of point (point) and appointment with the cursor position.Equally, the representative position of target can also be the coordinate of target image center, perhaps the position coordinates in the target image upper left corner.
In addition, cursor is operated, and cursor operations checkout equipment 29 is detecting the target image of cursor position with subject object (apart from the target at cursor proximal most position place) when overlapping, with this advisory target display control apparatus 27.In a single day the target display control apparatus receives this notice, just describes to make that the show state of subject object changes with respect to its former show state, and the target image of subject object is emphasized to show.For example, describe to make it to become the show state that the subject object image is surrounded shape with thick line to it.So, the user just can discern more clearly and be presented at the uppermost subject object of display frame.
Meanwhile, the show state of cursor operations checkout equipment change cursor.For example, be under the situation of cross mark at cursor, it is become arrow mark and show.By the change of this cursor show state, cursor operations checkout equipment 29 makes that the demonstration control of these target details of expression is intelligent under the situation of the operation of having carried out the overlapping target image of selection and cursor (clicking operation).Therefore, even under the state that the cursor show state does not change, clicked target image, can not open a window that shows these target details yet.
By such control, the target image that has shown the subject object nearest in the top of the display frame of displayed map image apart from cursor, in case cursor moves to and this target image position overlapped place, because the show state of target image, cursor changes, so the user can clearly discern the position whether cursor has moved to desired target image.
And, owing to only just making the window intellectuality of display-object details under these conditions, even because error has carried out making cursor and the equitant maloperation of undesired target image from overlapping target image, the user also can identify this misoperation easily.In addition, the undesired target image of having clicked (selection) even carried out such maloperation can not opened a window that shows its details, the unnecessary operation of returning picture of having avoided the operator originally may have to carry out thus yet.
Fig. 5 shows the front view (FV) as the cell phone appearance with navigation terminal function of map display 20.This map display 20 (mobile phone) has the display device 26 that is made of LCD assembly etc., the operation input apparatus 25 that keyboard, button etc. constitute.Display menu picture and map image etc. in display frame 261.The roller bearing key SK that is arranged in the operation input apparatus 25 is made of as shown in Figure 5 key up and down, if operation roller bearing key SK, display highlighting (roller bearing cursor) image in display frame 261 just, and can make the cursor up down move left and right.
The initial position of cursor begins to represent with a straight line that connects them till the shift position of cursor C from initial position in the central authorities of display frame 261.Along with moving until it, cursor arrives display frame 261 ends, according to the mode that makes the cursor position of this moment become the central authorities of display frame 162 map image that rolls.Because connect with straight line between cursor position and the initial position, the move operation cursor makes it return the initial position that just can easily get back to cursor according to this straight line.In addition, the input operation till also can being scavenged at this moment by operation clear key 251 etc.
In display frame, show the map image begin most generally speaking, this moment map display 20 present position and the center that all is configured to be presented at map image such as the POI position of having in mind.Therefore, the initial position of cursor and present position, to have place etc. in mind be consistent, in moving cursor rolling map, also can easily allow the cursor straight line return, and gets back to initial map image state thus, improved operation ease.So roller bearing and cursor control technology for example can be suitable for the spy and open the technology that is disclosed in the 2003-208095 communique.
Fig. 6 shows the figure of the example of target picture shown in the display frame 261 of showing map display 20.The map image that is presented among Fig. 6 in the display frame 261 has been omitted in diagram.On map image, target image IO1, IO2 etc. that expression is present in targets such as the facility of each position on the map and buildings are depicted on this map image.For the detail map of city part etc., owing in narrow zone, be intensively distributed with a plurality of targets, so the image demonstration that can overlap as target image IO2.
Therefore, at user's moving cursor of map display 20 on any target, carry out selection operation (clicking operation) by making cursor overlap, show thus under the situation of its details, desired target image is displayed on the following of other target image and will be difficult to identification as the target image of purpose, also can't utilize cursor reliably to implement selection operation in addition.
The present invention when the operation cursor, calculates the distance of cursor position and each target image as mentioned above, and the target image nearest by the cursor position of adjusting the distance redraws, and makes this target image be presented at the top of display image.So, being presented at the uppermost target image of picture generally is the target image nearest apart from cursor.
Therefore, user's moving cursor by making this target image be presented at the top of display frame, makes it possible to easily discern this target image up to making desired target image be presented at topmost.When the user wants the select target image to show its details, can also operate further that cursor makes it and target image is overlapping and carry out clicking operation.At this moment, because desired target image is presented at the top of display frame, make cursor move to the generation of the maloperation on other target image so can reduce because of error.
Detect desired target image and cursor overlapping in, further make the show state of cursor and change with respect to common show state among the present invention, and emphasize to show with the show state of the overlapping target image of cursor.Meanwhile, by making the show state of cursor change, also make to the demonstration control of the window that shows selected target details intelligent.Therefore, the user can correctly discern desired target and easily carry out selection operation.Even when making cursor and undesired target image overlapping, also can allow the user easily recognize its misoperation owing to maloperation.In addition, under this misoperation situation, even the undesired target image of having clicked (operation) can not opened the window of demonstration details, so avoided allowing the user have to get back to the unnecessary operation of picture yet.
Fig. 7 shows the figure of the demonstration example of utilizing the shown target image of so control.Promptly, as shown in Figure 7, the top that will the target image IO2 nearest be presented at display frame apart from cursor, and, in case cursor moves on it and overlaps, when the show state of target image IO2 changes the show state that becomes thick frame demonstration, make the show state of cursor also become the sensing image from cross image.By the variation of this cursor show state, make that the demonstration control of details display window of this target is intelligent.
Then, the step display to the target image in the map display 20 of as above explanation describes.Fig. 8 shows the process flow diagram of the treatment step of the subroutine of target image on the map image that is shown on the display device 26.
At first, cursor operations checkout equipment 29 detects the center of cursor in the processing of step S101, then, the target data of reference each target as shown in Figure 4 calculates its center in the processing of step S102, calculates the distance between cursor position and each target's center position in the processing of step S103 respectively.
Then, in the processing of step S104, subject object decision device 281 will be subject object apart from the target decision of cursor distance the shortest (nearest apart from cursor) with reference to each target that is calculated by cursor operations checkout equipment 29 and the distance between the cursor.Then, cursor operations checkout equipment 29 in the processing of step S105, judges that in step S104 cursor is whether on the target image of institute's decision objects target.
In the judgment processing of step S105, cursor operations checkout equipment 29 is judged when cursors are not positioned on the target image of subject object, the processing that then enters step S106, and the target image of 27 pairs of subject object of target display control apparatus redraws.By this processing, during cursor operations, be positioned at apart from cursor the most nearby the target image of position can be presented at the top of display image.Then, in the processing of step S107, cursor glyph uses common cross image to describe.Then, in the processing of step S108, owing to do not select any one target image, thus also can in software, be stored in the situation that does not have focus (cursor does not have overlapping) on the specific objective image, so remove the pointer in (cancellation) this software and return.
On the other hand, in the judgment processing of step S105, the cursor operations checkout equipment determines cursor when being positioned on the target image of subject object, enter the processing of step S109, target display control apparatus 27 is varied to as shown in Figure 7 show state (being to be varied to the image that surrounds with thick frame in the example of Fig. 7) with the target image of subject object, redraws.Handle by this, make the subject object image nearest be in the top of display image, and use the show state that is different from common mode to emphasize to show apart from cursor.That is, the subject object image is presented at the top of display frame, and becomes the focus of being paid close attention to.
Then be the processing of step S110, variation has taken place from common show state (cross image) in cursor glyph, uses different show state (for example, sensing type image) to come it is described.Here, can show according to making the cursor of arrow mark shape be in as the mode on the subject object image of focus.And, in the processing of step S111,, the pen travel on the software to this subject object image, is returned then for there is the fact of paying close attention in this subject object image from software identification.
Handle by this, reference pointer cursor as can be known is positioned at the fact on the target image of subject object, so can make that the clicking operation to this target image is effective.That is, in definite select target image, this target image is carried out clicking operation, allow the demonstration control intelligent (activate) of the window that shows this target detailed data.
If implement the display process of aforesaid target image, target display control apparatus 27 need be described being shown on the map image in the display frame existing target complete image, and its burden of describing to handle is very big.The user is at the operational light timestamp, and is in most cases just interested in the target image of specific region on the picture, need not usually target images all on the picture is shown.
Therefore, cursor operations checkout equipment 29 detects under the situation of moving direction of the operation of cursor and cursor, target selection equipment 282 is the interior target image of chosen distance cursor position preset range only, and its target image described, by the structure that such target display control apparatus 27 is only described target selection equipment 282 selected target images, can alleviate the burden of describing to handle of target display control apparatus 27.
If cursor operations checkout equipment 29 detects cursor operations, at first, carry out the processing of the step S101～S104 in Fig. 8 process flow diagram, try to achieve apart from cursor and describe the nearest target in position as subject object.For example, investigate the distance between the cross center of cursor and the centre coordinate of target image (POI position just) respectively, the target image that distance to a declared goal is nearest.
And target selection equipment 282 is selected following shown target.That is, investigate the distance of the target image nearest (subject object) whether below predetermined value apart from cursor.In the distance to subject object is not under the situation below the preset distance, owing to there is not nearer target image, so target selection equipment 282 is not selected any target, target display control apparatus 27 is only realized the processing of describing to cursor glyph (tracking cross), finishes then.
Here, for the distance between cursor and the target image, more suitable not as good as its distance on picture of investigation with the geographic distance of its investigation reality.For example, can be similar three unit sizes with the size definition of target image or be defined as * * the such numerical value of number of sites such as individual site.
The distance that arrives subject object is when preset distance is following, there is approaching target image in target selection equipment 282 owing to knowing, so select in the preset range, such as the target in the predetermined distance range, carry out the processing of step S105～step S111 in Fig. 8 process flow diagram then, target image.So, can reduce the target image that target display control apparatus 27 is described.
Fig. 9 shows the demonstration example of the target image under the control like this.As shown in Figure 9, when cursor moves, though initial near target image IO1 since to the distance L between the cursor 2 greater than preset distance (L0), so non-selected this target image, also enforcement redraws.If the continuation moving cursor, when target image IO2 becomes the target image nearest apart from cursor, and to the distance L 1 of cursor less than preset distance (L0), so target image IO2 is redrawn, it is presented at the top of display frame.Afterwards, carry out the whether overlapping judgement of cursor with subject object.
Utilize the selection of 282 pairs of targets of target selection equipment can also be suitable for other the whole bag of tricks except said method.For example, as shown in Figure 10,, can reduce the calculating and the ordering of adjusting the distance in the cursor operations checkout equipment 29 significantly by only selecting the mode of the target image in the preset range A1.Can also only select apart from the target image of cursor in the preset range of XY coordinate, perhaps under situation, select to include the target image in the grid of cursor with the more big map of grid dividing.
In addition, as shown in figure 11, detect by cursor operations checkout equipment 29 operation cursors and move the direction of (moving), the target image of selecting to be positioned on its direction also can.At this moment,, display frame can be divided into 4 quadrants of the 1st～the 4th, select to be positioned at the target image of this quadrant because cursor begins to move from the display frame center.Under the situation of Figure 11, owing to cursor moves to the 2nd quadrant, so select to be positioned at the target image in the 2nd quadrant A2 zone.And, as shown in figure 12, can also with the moving direction of cursor the center, scope will be dwindled the scope selection of regional A3 as the target image that becomes object at a predetermined angle.
By select, can alleviate to describe to handle the burden with calculation process according to Fig. 9～target selection mode illustrated in fig. 12.For example, in the example of Fig. 9, even the target nearest apart from cursor, but entered in the predetermined distance range owing to having only from cursor, just can begin to describe, so can reduce the frequency of describing.Do not have target near cursor, though far apart from cursor, it also is the icon nearest apart from cursor, just can avoid describing of futile effort that it is carried out for this icon.
In addition,, can limit the target that is used as object, be used to determine the ordering of the target nearest to handle apart from cursor so alleviated according to the method for Figure 10, Figure 11.
And, under the situation of Figure 12, owing to can limit target according to the target moving direction, so, need not its processing, thereby improved efficient especially for those targets far apart from cursor.
