  Therefore, there is a demand for a display device that can change the image displayed on the display screen so that the user can have an intuitive operational feeling when the user performs an operation of bringing two detection objects into contact with the display screen.

  According to the present invention, a characteristic configuration of a display device comprising: a display unit that displays an image on a display screen; and a contact position detection unit that can detect a contact position of a detection target that is in contact with the display screen. While detecting two detection objects, it is determined that the contact position of one detection object is a fixed contact position, and the contact position of the other detection object is moving When the moving contact position is determined, the image displayed on the display screen is divided into a fixed display area including the fixed contact position and a moving display area including the moving contact position, and the moving display is performed. The image processing apparatus includes a display changing unit that scrolls the image of the area according to the movement of the moving contact position and performs a divided one-side scroll process for fixing the image of the fixed display area.

  According to this feature configuration, an image to be displayed on the display screen can be divided into a fixed display area and a moving display area in accordance with a user operation, and the image in the moving display area can be moved to the moving contact position. It can be scrolled accordingly. That is, the image to be displayed on the display screen is divided, and in accordance with the movement of the contact position of the detection object moved by the user, the image of the moving display area including the contact position is scrolled and moved by the user. The image of the fixed display area including the contact position of the detection object that is not detected is fixed. Therefore, the image displayed on the display screen can be changed so as to give an intuitive feeling of operation according to the user's operation.

  Here, when the display change unit detects the two detection objects and determines that the contact positions of both the detection objects are moving contact positions, the display change unit It is preferable to perform enlargement / reduction display processing for enlarging or reducing the image according to the movement of the two moving contact positions without dividing the image to be displayed on the screen.

  According to this configuration, when the user moves both of the two detection objects, the image displayed on the display screen is not divided and enlarged or reduced according to the movement of the two detection objects. Is displayed. That is, the user changes the operation of changing the image displayed on the display screen by dividing one-side scrolling or scaling depending on whether one of the two detection objects is fixed and the other is moved or both are moved. be able to. Therefore, an intuitive operation feeling can be given to the user while enabling execution of such different types of image change processing according to the user's operation.

  Here, it is preferable that the display changing unit scrolls the image of the moving display area along a direction including a moving direction component of the moving contact position in the divided one-side scroll processing.

  According to this configuration, the image in the moving display area can be scrolled along a direction including a component in a direction in which the user moves the detection target. Therefore, the screen of the moving display area can be scrolled at least in the direction intended by the user, and an intuitive operational feeling can be given to the user.

  Here, the display change unit is configured to display the moving display when an image of a predetermined specific item is included in a fixed reference range that is a predetermined range including the fixed contact position on the display screen. It is preferable that the image of the region is scrolled until an image of a specific matter of the same type as the specific matter included in the fixed reference range is displayed.

According to this configuration, the user can specify the specific item by the contact position of the detection object to be fixed, and can scroll the image displayed in the moving display area until the specified specific item is displayed. Therefore, the user designates a specific item to be searched by the detection object on the fixed side, and according to the movement of the detection object on the moving side, the user searches the specific item of the same type as the specified specific item and enters the moving display area. Can be displayed. At this time, the image in the moving display area is scrolled until a specific item is displayed, so that the user can understand the positional relationship between before and after scrolling.
In addition, since the image of the specific item specified by the detection object on the fixed side is maintained as it is displayed in the fixed display area, the user can display the specific item displayed in the fixed display area on the same display screen. And the specific items displayed in the movement display area after scrolling can be compared, and the convenience for the user can be improved.
In addition, the user can perform the search scroll display of the above-mentioned specific items with a single operation of fixing one detection object and moving the other detection object. Thus, it is possible to obtain a convenient display of search results.

The scene of searching for a specific feature of the same type is assumed, and information on the distance between the specific features is important. According to the above configuration, the information on the distance between the specific feature displayed in the fixed display area and the specific feature displayed in the moving display area can be provided to the user. Convenience can be improved.

  Here, the display change unit includes a plurality of predetermined specific images in an image displayed within a fixed reference range that is a predetermined range including the fixed contact position on the display screen. In this case, one specific item is selected from the plurality of specific items, and the image of the moving display area is scrolled until an image of the specific item of the same type as the selected specific item is displayed, It is preferable to display a list of other specific items not selected among the specific items on the display screen.

  According to this configuration, even when a plurality of specific items are included in the fixed reference range including the fixed contact position, and it is difficult to accurately determine the specific items specified by the user, the display change unit is configured based on the plurality of specific items. Since one specific item is selected and the image of the moving display area is scrolled until an image of a specific item of the same type as the selected specific item is displayed, the specific item can be searched and displayed. In addition, since a list of other specific items that are not selected from among the plurality of specific items is displayed on the display screen, the user can easily display the displayed specific items and other specific items that are not displayed. I can grasp it.

  Here, when one specific item is selected from the other specific items displayed on the list by the user, the display change unit displays the image of the moving display area as the selected one specific item. It is preferable to scroll until an image of a specific item of the same type is displayed.

  According to this configuration, when the image of the specific item displayed in the moving display area is an image of the specific item that is not intended to be searched, the user wants to search from other specific items displayed in the list. One specific item can be selected, and an image of the specific item to be searched can be scrolled and displayed in the moving display area. Therefore, even when there are other specific items in the vicinity of the specific item to be searched, the image of the specific item to be searched can be finally displayed in the moving display area.

  Here, the display change unit includes a plurality of predetermined specific images in an image displayed within a fixed reference range that is a predetermined range including the fixed contact position on the display screen. In this case, the list of the plurality of specific items is displayed on the display screen, and when one specific item is selected from the plurality of specific items displayed on the list by the user, an image of the moving display area is displayed. It is preferable to scroll until an image of a specific matter of the same type as the selected one specific matter is displayed.

  According to this configuration, even when there are other specific items in the vicinity of the specific item to be searched, the user selects one specific item to be searched in advance, searches the selected specific item, and moves the display area. Can be displayed. Therefore, it can suppress that the specific matter which the user did not intend to search is searched and displayed in a movement display area, and can improve a user's convenience.

  Here, the display change unit performs the divided one-side scroll processing on the condition that a predetermined specific image is included in a predetermined range including the fixed contact position on the display screen. It is preferred to do so.

  According to this configuration, the divided one-side scroll process is performed when the user intends to search for or compare an image of a predetermined specific item, and the divided one-side scroll process is not performed in other cases. can do. Therefore, user convenience can be improved.

  Here, it is preferable that the display changing unit displays the image of the dividing boundary line that divides the fixed display area and the moving display area with a thickness corresponding to the scroll amount of the image of the moving display area.

It has the feature in performing.
Hereinafter, the configuration of the display device 1 and the display screen 2 according to the present embodiment will be described in detail.

1. Display screen 2
The display screen 2 is a touch panel and can detect a function as a display panel that can display an image and a contact position on the display screen 2 of a detection target that is in contact with the display screen 2. And a function as a contact sensor.
As the display panel, for example, a liquid crystal panel or a plasma display panel is used. The display screen 2 includes an input terminal such as a video terminal to which an image signal is input, and displays the image signal input to the input terminal on the display panel.
For the contact sensor, various known systems such as a capacitance system are used. As the contact sensor, one that can sense at least two contact positions simultaneously, that is, one having a multi-touch function is used. An electrical signal output from the contact sensor is input to the display device 1 through a signal line or the like.

2. Display device 1
The display device 1 includes an arithmetic processing device such as a CPU as a core member, and also has a RAM (random access memory) configured to be able to read and write data from the arithmetic processing device, and data from the arithmetic processing device. It has a storage device such as a ROM (Read Only Memory) configured to be readable. Each function unit 30 to 32 of the display device 1 is configured by software (program) stored in the ROM or the like of the display device 1 or hardware such as a separately provided arithmetic circuit, or both. . A display program for causing the arithmetic processing unit to realize the functions of the functional units 30 to 32 is stored in a storage unit such as a RAM or a ROM that can be referred to by the arithmetic processing unit.

2-1. Display unit 30
The display unit 30 is a functional unit that displays an image on the display screen 2.
The display unit 30 generates an image signal for displaying the image determined by the display change unit 32 or the like on the display screen 2 and outputs the image signal to an output terminal such as a video terminal provided in the display device 1. An output terminal of the display device 1 is connected to an input terminal of the display screen 2 so that an image signal can be transmitted by a signal line or the like.

The image displayed on the display screen 2 may be any image as long as it can be displayed on the display screen 2. For example, there are images such as maps, contents on the Web, photographs, sentences, and tables. The image displayed on the display screen 2 may be an image stored in a storage unit included in the display device 1 or may be an image acquired by the display device 1 from an external storage device or a network.
In the embodiment described below, a case where an image to be displayed on the display screen 2 is a map image will be described as an example.

2-2. Contact position detector 31
The contact position detection unit 31 is a functional unit that detects the contact position of the detection target that is in contact with the display screen 2.
In the present embodiment, the contact position detection unit 31 detects the contact position of the detection object in contact with the display screen 2 based on the electrical signal output from the contact sensor provided on the display screen 2. The detection target object in contact with the display screen 2 is typically a user's finger, a touch pen, or the like.

  The contact position detection unit 31 can detect a contact position on the display screen 2. The contact position detection unit 31 can also detect the movement of the contact position. In the present embodiment, the contact position detection unit 31 is configured to detect and store the contact position for each predetermined sample time.

  The contact position detection unit 31 can simultaneously detect at least two contact positions. For example, when the user touches the display screen 2 with two fingers, the contact position detection unit 31 can detect the contact position of each finger. And the position detection part 20 can also detect the movement of each contact position.

2-3. Display change unit 32
As described above, the display change unit 32 is a functional unit that executes display change processing such as divided one-side scroll processing and enlargement / reduction display processing. Here, the divided one-side scroll processing detects two detection objects, determines that the contact position of one detection object is a fixed contact position Pf, and determines one other detection object. When it is determined that the contact position of the object is the moving contact position Pt, the image displayed on the display screen 2 is displayed as a fixed display area Af including the fixed contact position Pf and a moving display area including the moving contact position Pt. In this process, the image in the moving display area At is scrolled according to the movement of the moving contact position Pt, and the image in the fixed display area Af is fixed. In addition, the enlargement / reduction display process detects two detection objects, and if it is determined that the contact position of both detection objects is the moving contact position Pt that is moving, the display screen 2 is displayed. In this process, the image to be displayed is enlarged or reduced according to the movement of the two moving contact positions Pt without dividing the image to be displayed.
Hereinafter, the process of the display change part 32 is demonstrated in detail.

2-3-1. Determination of Contact Position The display changing unit 32 is a fixed contact position Pf where the contact position of the detection target is fixed or a movement where the contact position of the detection target is moving based on the movement locus of the contact position. It is determined whether the contact position is Pt. The display changing unit 32 is configured to determine the moving direction Y of the contact position, the moving speed, and the like.

  In order to improve the response to the user's operation, when the amount Z of movement of the contact position becomes larger than a predetermined determination threshold value, it is determined that the position is the moving contact position Pt, and it is desired to start the divided one-side scroll process. However, when both of the contact positions of the two detection objects are moving, the contact position with the slower moving speed may be erroneously determined as the fixed contact position Pf, and the divided one-side scroll process may be erroneously started. There is. For example, as shown in the comparative example of FIG. 3, when the amount of movement Z at the contact position of one of the fast moving speeds (the right side of FIG. 3) is larger than the determination threshold value X4, the other moving speed is slow. When the movement amount Z of the contact position (left side in FIG. 3) is equal to or less than the determination threshold value X4, the contact position with the slower movement speed may be erroneously determined as the fixed contact position Pf.

Therefore, in the present embodiment, as shown in FIG. 2, the display changing unit 32 has a first determination threshold value in which the movement amount Z of the contact position from when the contact of the detection target is newly detected is determined in advance. If it is less than or equal to X1, the fixed contact position Pf is determined, and when the movement amount Z is greater than a predetermined second determination threshold value X2 that is greater than the first determination threshold value X1, the moving contact position Pt It is configured to determine that there is. The display changing unit 32 determines both the fixed contact position Pf and the moving contact position Pt when the movement amount Z of the contact position is greater than the first determination threshold value X1 and equal to or less than the second determination threshold value X2. Not determined.
In FIG. 2 (the same applies to the other figures), the start position, which is the contact position when the contact of the detection object is newly detected, is indicated by “open white”, and is the current contact position. The current position is indicated by “black x”. In the example shown in FIG. 2, the contact position on the left side of the display screen 2 is determined to be the fixed contact position Pf because the movement amount Z from the start position to the current position is equal to or less than the first determination threshold value X1. The contact amount on the right side of the display screen 2 is determined to be the moving contact position Pt because the movement amount Z from the start position to the current position is larger than the second determination threshold value X2. The direction from the start position toward the current position is determined as the movement direction Y.

  According to this configuration, as shown in FIG. 4 (a), when both of the contact positions of the two detection objects are moving, one of the contacts that has a fast moving speed (right side in FIG. 4 (a)). When the movement amount Z of the position first becomes larger than the second determination threshold value X2 and is determined as the moving contact position Pt, the movement of the contact position on the other side (the left side in FIG. 4A) is slow. Since the amount Z is larger than the first determination threshold value X1 but not larger than the second determination threshold value X2, the contact position is not determined as the fixed contact position Pf or the moving contact position Pt. Therefore, it is possible to prevent the divided one-side scroll from being erroneously started against the user's operation. Thereafter, as shown in FIG. 4 (b), when the moving amount Z of the other contact position whose moving speed is slow becomes larger than the second determination threshold value X2, and is determined to be the moving contact position Pt, two detections are made. It is determined that both of the contact positions of the object are the moving contact positions Pt, and an enlargement / reduction display process is executed.

On the other hand, as shown in FIG. 4C, when one of the contact positions of the two detection objects is moving, the amount of movement of the contact position of one of the moving objects (the right side of FIG. 4C) When Z becomes larger than the second determination threshold value X2 and is determined to be the moving contact position Pt, the movement amount Z of the other non-moving contact position (left side in FIG. 4C) is first determined. Since it is equal to or less than the threshold value X1, the fixed contact position Pf is determined, and the divided one-side scroll process is started. Therefore, after the movement amount Z of the moving contact position becomes larger than the predetermined determination threshold value, the divided one-side scroll processing can be started immediately, and the response to the user operation can be improved.
Therefore, when two detection objects are detected, it is possible to improve the determination accuracy of the moving contact position Pt or the fixed contact position Pf, and it is possible to advance the start timing of the divided one-side scroll processing. Therefore, it is possible to improve the determination accuracy and response to the user operation.

2-3-2. Outline of Display Change Process The display change unit 32 starts display change processing such as divided one-side scroll processing and enlargement / reduction display processing when two detection objects are detected.
The outline of the display change process will be described with reference to the flowchart shown in FIG.
The display change unit 32 starts the display change process when two detection objects are detected (step # 01: Yes). If two detection objects are not detected (step # 01: No), no display change process is performed and the process is terminated (step # 08). Note that when two detection objects are not detected and one detection object is detected, a simple scroll process for scrolling the image so that the contact position of the detection object is the center of the display screen It is also suitable as a configuration for executing

The display changing unit 32 determines that the contact position of one detection target is the fixed contact position Pf, and determines that the contact position of the other detection target is the moving contact position Pt (step # 02). : Yes), the divided one-side scroll process is executed (step # 03 to step # 05).
In the present embodiment, when the display changing unit 32 executes the divided one-side scroll process, the specific item predetermined in the fixed reference range Ab that is a predetermined range including the fixed contact position Pf on the display screen 2 is specified. It is configured to determine whether or not a POI image is included (step # 03). When the image of the specific item POI is not included (step # 03: No), the display changing unit 32 moves the image of the moving display area At according to the moving amount Z of the moving contact position Pt. A moving direction scrolling process is performed to scroll along the direction including the component of the moving direction Y of the contact position Pt (step # 04). On the other hand, when the image of the specific item POI is included (step # 03: Yes), the image of the moving display area At is used for the specific item POI of the same type as the specific item POI included in the fixed reference range Ab. A specific item search scroll process for scrolling until an image is displayed is executed (step # 05).

On the other hand, when the display changing unit 32 determines that both of the contact positions of the two detection objects are the moving contact positions Pt (step # 02: No, step # 06: Yes), an enlargement / reduction display process is performed. Execute (Step # 07).
When the display change unit 32 determines that both of the contact positions of the two detection objects are the fixed contact positions Pf, or one or both of the contact positions of the two detection objects are not determined. If this is the case (step # 02: No, step # 06: No), no display change processing is performed and the processing is terminated (step # 08).
Note that the processing from the start to the end shown in the flowchart of FIG. 5 is repeatedly executed.
Hereinafter, each process such as the divided one-side scroll process (moving direction scroll process, specific item search scroll process) and the enlargement / reduction display process will be described in detail.

2-3-3. Split one-side scroll processing 2-3-3-1. Display Image Division Processing After the divided one-side scroll processing is started, the display change unit 32 displays an image to be displayed on the display screen 2 as a fixed display region Af including the fixed contact position Pf and a moving display region At including the moving contact position Pt. The division process is performed to divide into two. That is, the entire display area of the display screen 2 is divided into a fixed display area Af including the fixed contact position Pf and a moving display area At including the moving contact position Pt, and the fixed display area At and the moving display area At are separated. Display an image on each.
In the present embodiment, the display changing unit 32 sets a dividing boundary line Ld that divides the fixed display area Af and the moving display area At between the fixed contact position Pf and the moving contact position Pt. An image is displayed on the display screen 2. For example, as shown in FIG. 6, the division boundary line Ld passes through the midpoint Pc between the fixed contact position Pf (start position) and the moving contact position Pt (start position), and the fixed contact position Pf and the moving contact position Pt. Is set to extend in a direction orthogonal to the line connecting the two.
The display screen 2 on the fixed contact position Pf side with respect to the divided boundary line Ld is set to the fixed display area Af, and the display screen 2 on the moving contact position Pt side with respect to the divided boundary line Ld is set to the movable display area At. Set to
The dividing boundary line Ld may be set so as to pass through the middle point Pc and be parallel to the vertical side or the horizontal side of the display screen 2. In addition, the display change unit 32 may be configured to display the image of the divided boundary line Ld with a thickness corresponding to the scroll amount Zs of the image of the moving display area At. For example, it is preferable that the image of the dividing boundary line Ld has a thickness obtained by multiplying the scroll amount Zs by a certain coefficient (for example, 1/100). In the present embodiment, the image of the division boundary line Ld has a constant thickness regardless of the scroll amount Zs.

2-3-3-2. Determination of Specific Item POI As shown in FIG. 7, the display change unit 32 displays an image of the specific item POI that is predetermined within the fixed reference range Ab that is a predetermined range including the fixed contact position Pf on the display screen 2. Whether or not is included is determined.

In the present embodiment, the image displayed on the display screen 2 is a map image, and the specific item POI is a specific feature that is a predetermined type of feature.
Types of features that can be set as specific features include, for example, parking lots, gas stations, stations, convenience stores, restaurants, supermarkets, landmarks, and the like. The type of the feature set as the specific feature may be configured to be determined in advance according to the use application of the map image. For example, when the map image is for vehicle navigation, it may be determined in advance in a parking lot, a gas station, a restaurant with a parking lot, a supermarket with a parking lot, a convenience store with a parking lot, and the like. When the map image is for searching for restaurants, it may be determined in advance for each genre of restaurant such as a Chinese restaurant, an Italian restaurant, or an Indian restaurant. Alternatively, the type of the feature set as the specific feature may be configured to be predetermined by the user.

  In the present embodiment, the fixed reference range Ab is within a predetermined distance X3 set in advance from the fixed contact position Pf (start position). The display changing unit 32 determines whether an image of the specific feature POI is included in the fixed reference range Ab. For example, the display change unit 32 may be configured to determine whether or not the representative point of the image of the specific feature POI is included. The display change unit 32 may be an icon image representing the specific feature POI. It may be configured to determine whether or not a part or all of is included.

2-3-3-3. Moving direction scroll processing When the display changing unit 32 determines that the image of the predetermined specific item POI is not included in the fixed reference range Ab, the display changing unit 32 moves the image of the moving display area At to the moving contact position Pt.
