Description

  The present invention relates to an image information display device and an image information display method, and more particularly to an image information display device and an image information display method that can change a display state of a displayed image by a user operation.

When displaying a map on an information terminal device such as a mobile phone or a personal computer (hereinafter referred to as a PC), the display magnification and display range of the map can be changed using a keyboard and a mouse.
At this time, the user performs a move operation for changing the display range while viewing the displayed map, an operation for changing the center of the display range (center setting operation), and a zoom-in operation or a zoom-out operation for adjusting the display magnification. Is displayed at a desired display magnification. In other words, in order to display a desired range of the map at a desired display magnification, the user has to operate a keyboard and a mouse.

  For this reason, in the process of viewing a map on a PC or the like, it has been desired to reduce the number of operations and the operation time to reduce the operation load. For example, Patent Document 1 discloses a conventional technique for reducing the load on the user's operation. Patent Document 1 describes a system that extracts a keyword from a user's operation history and estimates the user's intention (a point targeted by the user) using the keyword.

JP 2008-039879 A

The system described in Patent Document 1 described above automatically detects a point or region that the user wants to see, and provides information on the Web related to the detected point. Such a system described in Patent Document 1 does not reduce the load on the user by reducing the number of times the user operates and the time required for the operation.
Moreover, in patent document 1, the individuality and custom of a user's operation are not considered. For this reason, there is a possibility that sufficient accuracy cannot be obtained for estimation. That is, when a user views “Shibuya” on a map, for example, a user who has knowledge of “Shibuya” generally displays a map at a relatively high display magnification. On the other hand, a user who does not know about “Shibuya” tends to display a wide area map at a relatively low display magnification. Therefore, in order to automatically display a map as intended by the user, it is necessary to reflect the operation characteristics for each user in the process.
In order to solve the above problems, the present invention estimates a map that the user wants to display with high accuracy based on a characteristic operation when the user browses the map while reducing the load on the operation, An object of the present invention is to provide an image information display device and an image information display method that can be displayed.

(Outline of image display system including image display device)
FIG. 1 is a functional block diagram for explaining the image information display apparatus of the present embodiment, and shows an image display system including the image display apparatus of the present embodiment. The illustrated image information display system includes an image information display device and an image information providing device. In the present embodiment, the image information providing apparatus is a server apparatus that supplies image data (hereinafter referred to as map information) for representing a map as an image to the image information display apparatus. The image display device is a mobile communication terminal such as a mobile phone that receives and displays map information. For this reason, the image information providing device of the present embodiment is referred to as a map information providing device 1, and the image information display device is referred to as a map information display device 2.

The map information providing device 1 provides map information to the map information display device 2 via the Internet or the like.
The map information providing apparatus 1 includes an operation reception unit 101, a map information storage unit 104, a map information acquisition unit 112, and a map information display unit 113. Such a configuration is a configuration generally provided in a mobile phone or the like. The operation receiving unit 101 receives and interprets the operation content of the user interface such as a button. The map information acquisition unit 112 has a function of receiving image data representing text and drawings via the Internet. The map information display unit 113 is a display screen for displaying acquired text and image data and its control engine.

In the image display apparatus according to the present embodiment, a characteristic pattern of a user operation is extracted from the operation history received by the operation receiving unit 101 and stored in a table. Then, an operation pattern is also detected for operations performed thereafter, and when the detected operation pattern matches a characteristic pattern stored in the table, the operation to be performed by the user is estimated. Further, a map that is likely to be displayed by the estimated operation is displayed.
In order to enable such processing, the map information display apparatus 2 according to the present embodiment compares the operation received by the operation receiving unit 101 with the operation pattern master stored in the operation pattern master storage unit 107 in advance. Thus, a history storage determination unit 108 that determines whether or not the operation should be stored in the operation history storage unit 102 is provided.

Further, based on the operation history stored in the operation history storage table 103 and the operation history storage table 103, the operation history determined to be saved by the history storage determination unit 108 is stored in the operation history storage table 103. A map area (hereinafter simply referred to as an area), an operation feature calculation unit 105 that extracts a characteristic pattern of an operation performed on the area, and a characteristic calculated by the operation feature calculation unit 105 An operation feature storage unit 110 in which a pattern is recorded as the operation feature storage table 111 and a feature matching determination unit 106 that compares the received operation with the operation feature storage table 111 and selects a predicted value are provided.
Furthermore, a map information storage unit 104 that stores map information that is requested to be displayed by a user operation (hereinafter referred to as a cache) and a trigger operation determination unit 109 that determines the timing of map display are provided.

Hereinafter, each of the above-described configurations will be described.
(Each component of the map information display device)
-Operation reception part The operation reception part 101 receives the operation information which shows operation of the operation button which is not shown in figure, and detects the content of operation. The content of the operation means any one of movement of the display area of the map, setting of the center point of the display area, enlarged display (zoom in) of the map, and reduced display (zoom out) of the map. Hereinafter, the movement of the display area is also indicated by the symbol “M”, the setting of the center point “C”, the zoom-in “I”, and the zoom-out “O”.

Operation Pattern Master FIG. 2 is a diagram illustrating an operation pattern master stored in the operation pattern master storage unit 107 shown in FIG. There are three types of operation pattern masters exemplified, and each is identified by an ID number. In the present embodiment, there are three IDs “i”, “ii”, and “iii”, which are referred to as operation pattern master i, operation pattern master ii, and operation pattern master iii, respectively.

In addition, the symbol “+” shown in the figure indicates that the same operation is continuously performed, and the symbol “*” indicates that the operation indicated on the left of the symbol * is performed several times. Indicates that the operation indicated to the right of the symbol * is performed. “Trigger” in the figure refers to an operation recorded as an operation corresponding to the operation pattern master in a series of operations. Such an operation is also referred to as a trigger operation.
“Recorded contents” in the figure is information indicating the display magnification recorded in association with the operation pattern master or the area and point (hereinafter also referred to as display point) displayed on the map. In the present embodiment, the display point is represented as a center point when a map is displayed.

(Operation pattern master i)
The operation pattern master i indicates an operation in which zoom-out is continuously performed. In the operation pattern master i, the second zoom-out operation is a trigger operation, and a map of the zoom-in I display magnification performed last is displayed.
Such an operation pattern master i is set for the following reason. That is, the user's operation of continuously zooming out is considered to have a purpose of moving a display area after displaying a certain area on a map or displaying a wider map area.

The operation pattern master i is set so that there is a high possibility that the zoom-out operation will be further performed when the zoom-out is continuously performed. For this reason, according to the operation pattern master i, the map information of the final display magnification obtained by the continuous zoom-out performed in the past is displayed at the timing when the zoom-out O is performed twice in succession. The Here, “final display magnification map information” refers to a map displayed immediately after the last zoom-out O among the continuously performed zoom-out Os.
According to this embodiment, the user can display a map with a desired display magnification with a smaller number of operations.

(Operation pattern master ii)
The operation pattern master ii indicates an operation in which the zoom-in I is continuously performed after the movement M is performed a plurality of times. Such an operation is generally performed when the user narrows down and searches for points to be displayed from the display area. The operation pattern master ii is set so that if the zoom-in I is performed after the movement M is performed a plurality of times, the zoom-in I is more likely to be repeated.

For this reason, according to the operation pattern master ii, the map information of the final display magnification obtained by the zoom-in I after the continuous movement M performed in the past is displayed at the timing when the zoom-in I is performed. . Here, the “map information of the final display magnification” refers to the zoom-in I performed following the movement M, or the zoom-in I performed further after the zoom-in I, immediately after the final zoom-in. Refers to the displayed map.
According to this embodiment, the user can display a map with a desired display magnification with a smaller number of operations.

(Operation pattern master iii)
The operation pattern master iii indicates an operation in which the movement M is continuously performed. Such an operation is generally performed when the user performs a peripheral search or a route search. The operation pattern master iii is set so that there is a high possibility that acquisition of map information acquired in the past is required when the movement M is continuously performed.
For this reason, the display point of the map finally displayed by the past movement M when the movement M is continuously performed is recorded in the operation pattern master iii. Here, “finally displayed map” refers to a map displayed immediately after the last movement M of the movements M performed continuously.

According to this embodiment, the user can display a map with a desired display magnification with a smaller number of operations.
In the operation pattern master iii, a map is displayed at the timing when the user accesses a display point indicated by map information cached in the map information storage unit 104. Note that “access” means that the user instructs display of map information including a display point by a movement operation, input of a display point, or the like.

  Such a trigger operation of the operation pattern master iii is the first movement M. In the case of the operation pattern master i and the operation pattern master ii described above, the map information cached in the map information storage unit 104 is immediately displayed, that is, displayed synchronously. On the other hand, in the case of the operation pattern master iii, since the map information cached in the map information storage unit 104 is not immediately displayed, the display timing is set asynchronously. According to such an operation pattern master iii, map information that is frequently requested for acquisition is stored in the map information storage unit 104 shown in FIG. 1 to improve the responsiveness of map information acquisition or in an offline environment. Browsing of map information can be realized.

History Storage Determination Unit The history storage determination unit 108 compares operations sequentially received by the operation reception unit 101 with the operation pattern masters i to iii. Then, as a result of the comparison, control is performed so that an operation that does not correspond to any of the operation pattern masters is not stored as an operation history. On the other hand, for an operation corresponding to one of the operation pattern masters, control is performed so that the history of the operation is stored in the operation history storage unit 102, and the operation corresponds to any of the operation pattern masters i, ii, and iii. Judge whether or not. The determination result is recorded in the operation history storage table 103 of the operation history storage unit 102.

Operation History Storage Unit FIG. 3 is a diagram illustrating the operation history storage table 103 illustrated in FIG. “Operation” in the operation history storage table 103 is an operation such as zoom-out O and movement M. “Operation pattern master ID” is the value of the operation pattern master ID corresponding to the operation. “Area” is an area displayed by map information, and the area being displayed when this operation is executed is represented by area codes such as R1 and R2.

“Result” indicates the final display magnification or map information display point obtained by the operation. Among the results, Z1 and Z2 are final display magnifications of the map information. The display magnification is set in N stages (N is a natural number) up to Z1, Z2,... ZN. Although the specific value of the display magnification varies depending on the specifications of the image display device, for example, it is conceivable that Z1 is 1/20 m and ZN is 1/50 km.
Moreover, the display point of map information is represented by (A2, B2), for example. The display points (A2, B2) are information described on the basis of latitude and longitude, and represent the center point of the displayed map. The center point does not change depending on the map display magnification.

“Date” is the date on which the operation was performed. This “date” may include not only the date but also the time (hour / minute / second) at which the operation was performed. The “considered category” is information indicating whether or not an operation feature has been extracted by the operation feature calculation unit. “Y” in the “considered category” is a flag indicating that the operation feature has been extracted.
The reason for storing “area” in the operation result is that the final display magnification is likely to be different depending on the map information being browsed. For example, the final display magnification may be different between when you zoom out continuously to find a store in Shibuya shopping street and when you zoom out continuously to examine the tracks in the suburbs of Nasu Kogen. Is considered high.

-Operation feature calculation unit The operation feature calculation unit 105 is based on the operation history stored in the operation history storage table 103, "region", an operation pattern master corresponding to the operation executed in this "region", The content recorded in association with the operation pattern master (hereinafter referred to as a predicted value. In this embodiment, the display magnification or display point of map information) is calculated as a set of data (hereinafter referred to as a record). To do. The record is stored in the operation feature storage table 111. The operation feature calculation unit 105, when the records having the same “area”, “operation pattern master ID”, and “predicted value” are already stored in the operation feature storage table 111, Count up the number of storages by one. Also, the storage frequency is updated.

Operation Feature Storage Table FIG. 4 is a diagram illustrating the operation feature storage table 111 shown in FIG. As described above, the operation feature storage table 111 stores a plurality of records, and “recording frequency” and “storage frequency” of the records. In the present embodiment, records having the same “area” and “operation pattern master ID” are grouped. In the example shown in FIG. 4, the record 401 shown at the top and the record 402 at the next belong to the same group.

The operation feature storage table 111 further records “use classification” information. The “usage classification” is determined based on the number of storage times of records belonging to the same group, and a flag “Y” is recorded in the record with the largest number of storage times.
In the present embodiment, among records belonging to the same group, a record having the largest number of times of storage, that is, a predicted value of a record in which a flag of “Y” is recorded in the usage category is employed for display of the map. When there are a plurality of records having the same number of times of storage, a predicted value of a record with a high storage frequency or a record with the latest “date” may be adopted.

Feature Matching Determination Unit The feature matching determination unit 106 determines the “area” where the operation received by the operation receiving unit 101 has been performed and the value of the “operation pattern master ID”. Then, a record in which the flag “Y” is recorded in the usage category is selected from the records in which the values of “area” and “operation pattern master ID” match. The predicted value of the selected record is transmitted to the operation receiving unit 101.

Trigger Operation Determination Unit The trigger operation determination unit 109 determines from the operation history stored in the operation history storage table 103 whether the operation received by the operation reception unit 101 is a trigger operation. When the trigger operation determining unit 109 determines that the operation is a trigger operation, the operation receiving unit 101 transmits the trigger operation and the value of the operation pattern master ID corresponding to the operation.

Map Information Acquisition Unit The map information acquisition unit 112 has a function of downloading the instructed map information from the map information providing device 1 every time it is instructed by the operation receiving unit 101.
Map Information Storage Unit The map information storage unit 104 is a cache memory that stores (that is, caches) downloaded map information. When map information including a display point that has not been accessed is cached in accordance with an instruction from the operation reception unit 101, the map information is “prefetched” in the map information storage unit 104.

Map Information Display Unit The map information display unit 113 displays a map based on the map information cached in the map information storage unit 104. At this time, the display magnification is designated from the operation reception unit 101 to the map information display unit 113. When the display magnification is designated, the map information display unit 113 operates the image data of the corresponding display magnification among the image data (that is, the map) of the plurality of display magnifications stored in advance by the user's operation. Displayed at the same timing as the pattern. However, only one type of display magnification image data (that is, a map) is stored, and a map with a corresponding display magnification is stored in the stored image data at the timing when the user operation matches the operation pattern. Create and display this creation.

(Operation of image display device)
Next, operations performed by the image display apparatus according to the present embodiment will be described in more detail.
Operation Performed by Operation Accepting Unit FIG. 5 is a flowchart for explaining the operation of the image display apparatus of the present embodiment, and describes the operation performed by the operation accepting unit 101 shown in FIG. The operation reception unit 101 receives operation information (step S501), and requests the trigger operation determination unit 109 illustrated in FIG. 1 to determine whether or not this operation is a trigger operation.
The trigger operation determination unit determines whether the operation is a trigger operation using the received operation and the operation history already stored in the operation history storage table 103 shown in FIG. 1 (step S502).

  Specifically, for example, it is determined whether or not the operation performed this time is the second operation of the zoom-out O that continues. If the operation is the second operation of the continuous zoom out O, it is determined that this operation is a trigger operation of the operation pattern master i. If the operation is zoom-in I following the continuous movement M, it is determined that this operation is a trigger operation of the operation pattern master ii. Furthermore, if the operation of the movement M is continuously performed, it is determined that the first movement M is a trigger operation of the operation pattern master iii. The result of the determination is notified to the operation reception unit together with the value of the operation pattern master ID.

In step S502, if the result of the determination is a trigger operation (step S502: Yes), the value of the operation pattern master ID is acquired in the operation reception unit 101 (step S503).
When it is determined that the operation is not a trigger operation (step S502: No), the operation reception unit performs normal processing that is not specialized in the present embodiment. That is, control such as acquisition and display of map information according to the user's operation is performed (step S505). At this time, the map is displayed on the map information display unit in a state as operated by the user.

Subsequently, the operation accepting unit stores the record in which the flag “Y” is recorded in the usage classification among the records in which the operation pattern master ID and the “region” match from the operation feature storage table 111 illustrated in FIG. 1. Get the predicted value.
At this time, the operation reception unit 101 determines whether or not the value of the operation pattern master ID is iii (step S504). If the value of the operation pattern master ID is “iii” (step S504: Yes), the display point as the predicted value is transmitted to the map information acquisition unit 112 shown in FIG. 1 (step S507). The map information acquisition unit 112 receives the display point transmitted from the operation reception unit 101 and requests the map information providing apparatus 1 for map information including the display point. The map information downloaded in response to this request is cached in the map information storage unit 104 shown in FIG. The cached map information is displayed as a map on the map information display unit 113 shown in FIG. 1 at the timing when the user accesses the display point.

  On the other hand, when it is determined in step S504 that the value of the operation pattern master ID is not iii (step S504: No), the operation reception unit displays the display magnification as the predicted value in the map information display unit 113 shown in FIG. Send to. The map information display unit displays the currently displayed map information or the map displayed after movement enlarged or reduced according to the display magnification. If no predicted value is set in the operation feature storage table, a map is displayed by the normal processing in step S505.

  Here, a specific example of map display will be described with respect to the operation pattern master IDiii. For example, it is assumed that the user performs the operation of the movement M a plurality of times in order to investigate the route to the target or the target point in the Shibuya area. If the user has moved M several times in the Shibuya area, if the possibility of referring to Shibuya Station is high, the flag “Y” in the operation feature storage table is a display point whose predicted value indicates Shibuya Station. It is recorded in a record.

  In such a case, in this embodiment, the map information acquisition unit requests map information including Shibuya Station from the map information providing device, and the requested map information is cached in the map information storage unit. For this reason, when the user performs an operation to display Shibuya Station (corresponding to “the user accesses the display point indicated by the map information” described above), the already cached map information is displayed on the map display unit. . Thus, according to the present embodiment, image information that includes Shibuya Station and that the user wants to display can be displayed in a shorter time.

FIG. 6 is a flowchart for explaining the operation performed by the history storage determining unit 108 shown in FIG. The history storage determining unit sequentially receives the operations received by the operation receiving unit 101 (step S601), and compares the contents of the received operation with the operation pattern master shown in FIG. 2 (step S602). From this comparison, it is determined whether or not the operation is any trigger operation of the operation pattern master, that is, whether or not the operation should be recorded in the operation history storage table (step S603).

  When the history storage determining unit determines that the operation should be recorded, the history storage determining unit transmits the value of the operation pattern master ID corresponding to the operation to the operation receiving unit. When receiving the ID, the operation reception unit records the type of trigger operation, the “area” where the operation was performed, the display magnification and display point of the map finally displayed, and the operation date in the operation history storage table. The operation history storage unit 102 is requested. The operation history storage unit records the information requested to be recorded as the operation history storage table shown in FIG. 3 (step S604).

Operation for Extracting Operation Feature Next, a process performed by the operation feature calculation unit 105 illustrated in FIG. 1 will be described. The operation feature calculation unit periodically performs a feature extraction operation from the operation history information stored in the operation feature storage table. FIG. 7 is a flowchart for explaining processing for extracting operation features from operation history information.
The operation feature calculation unit obtains a record in which the flag “Y” is not recorded in the “considered classification” from the operation history storage table (that is, it has not been considered) (step S701). Then, the operation feature storage of other records in which the “operation pattern master ID”, “area”, “result” of the acquired record and “operation pattern master ID”, “area”, “predicted value” coincide with each other is stored. The table is searched for (steps S702 and 703).

  As a result of searching the operation feature storage table, if a matching record is detected, the “number of times” of the detected record is incremented by one (step S704). The operation feature calculation unit also calculates and updates the “frequency” of the record whose “number of times” is counted up. The frequency can be represented by an average value of time intervals in which the “number of times” is counted up.

If the retrieved record does not exist in the operation feature storage table, the acquired record of the operation history storage table is stored in the operation history storage table as a new record in step S701. At this time, the stored new record is set so that the “number of times” is 1, the “frequency” is 0, and the “use category” flag is not recorded.
In step S <b> 701, the flag “Y” is recorded in the “time-considered classification” in the record acquired by the operation feature calculation unit. The processing in steps S701 to S705 is performed until there is no record in which the flag “Y” is not recorded in the “considered classification” in the operation history storage table (that is, until the flag “Y” is recorded in all records). This is repeated by the operation feature calculation unit (step S705).

  Next, the operation feature calculation unit groups records having the same “area” and “operation pattern ID” values among records stored in the operation feature storage table. Then, the records included in the group are ranked in descending order of the “number of times” (step S706). As a result of the ranking, it is determined whether or not the flag “Y” is recorded in the “use classification” of the record having the largest “number of times” (step S707). If the flag “Y” is not recorded in the “usage classification” of the record having the largest “number of times” (step S707: No), the flag “Y” is recorded in the “usage classification” of this record, and the same group The usage classification of the other records belonging to is made blank (step S708).

  According to the present embodiment described above, when the user zooms out four times in succession and tries to display a map with a lower display magnification, for example, the second zoom-out results in zooming out four times. A map with a display magnification can be displayed. For this reason, the intended map can be provided to the user with a smaller number of operations (that is, map information can be displayed). For example, when the user tries to display the target building or the like by moving three times, map information including the building is acquired at the time of moving twice, and immediately displayed when the user accesses the image including the building. be able to. For this reason, the time from the operation to the image display can be shortened to reduce the operation load on the user.

Further, since the image intended by the user is extracted using a predetermined operation pattern extracted from the operation history by the user, it is possible to display an image with high estimation accuracy in consideration of the user's personality and customs. .
Furthermore, the present embodiment is not limited to detecting movement, center point setting, zoom-in and zoom-out operations, and may detect other operations. As other operations, for example, adjustment of the color of an image and change of a font of a language or a character can be considered. Moreover, this embodiment is not limited to the structure which displays map information on a mobile communication terminal, It is applied also to the apparatus etc. which display map information on general PC. When applying a device that is more likely to be shared, such as a PC, to an image display device, it is obvious that each user is identified by an ID, etc., and an operation history is recorded for each user to extract operation characteristics. Nor.

  The present invention can be applied to a system device that downloads a map from a server device to a mobile phone or a PC. Further, even if it is not a map, it can be applied to any device as long as it is an apparatus that downloads image data from a server device to a mobile phone or a PC and processes the displayed image.
