Description

  The present invention relates to a technique for dividing and displaying an image having a size that cannot be displayed on one display unit, such as a large map image, using a plurality of display devices having a display unit for displaying an image. In particular, the present invention relates to a suitable image browsing technique using electronic paper having a function of displaying and holding an image on a display unit in a non-powered state as a display device.

For example, document data created by a document processing apparatus or content data acquired from a network is displayed as an image on a display screen of a personal computer, or printed as an image on a paper medium by a printer. It is used for browsing.
That is, a document made up of electronic data is visualized as an image and used for user browsing.

In recent years, as an image browsing medium that can replace paper, which is a paper medium, an image that can be displayed and held on a display unit in a non-powered state, is flexible, thin, and portable like a paper Paper is being developed.
Electronic paper is a display device having a display unit that displays and holds an image in a non-powered state. When the image is roughly classified according to the writing format of the image on the display unit, the image is written on the display unit by itself based on electronic data. There are self-writing type electronic paper having a function and optical writing type electronic paper that holds a projected image on a display unit.
Unlike paper, such electronic paper can erase or overwrite the image displayed and held on the display unit, and can update or repeatedly use the image held on the display, saving paper resources. The use promotion is desired from the viewpoint of the above.

Here, the personal computer is also a display device that displays an image on the display screen. However, as a technology related to the personal computer, the display area of the display screen is divided into nine matrices, and an image related to the image displayed in the central area is displayed. A technique for displaying in a peripheral region is known (see Non-Patent Document 1).
In addition, in displaying an image based on electronic data, a technique for turning a page of an image displayed on the screen is known (see Patent Document 1 and Patent Document 2).
Further, a technique for enlarging or reducing a map image displayed on the screen in displaying a map image based on electronic data is known (see Patent Document 3).

The present invention will be specifically described based on examples.
First, the electronic paper EP used in the present invention as a medium for displaying and holding a document will be specifically described with reference to the examples shown in FIGS.
The electronic paper EP is a self-writing type having a function of self-writing an image to be displayed and held on the display unit 2 based on image data, and is a thin and flexible display device like paper as called electronic paper. is there.
The various functions of the electronic paper EP described below may be selected according to the system mode for carrying out the present invention to be described later and provided in the electronic paper EP.

FIG. 11A shows the electronic paper EP of this example as viewed from the front, and FIG. 11B shows the electronic paper EP as viewed from the side. The illustrated electronic paper EP has a display unit 2 that displays and holds an image (in this example, a divided partial map image) and a processing unit 3 that manages data processing. FIG. 3 also shows various function units built in the device.
The electronic paper EP is a flexible thin display device having a size like, for example, A4 size paper, and the processing unit 3 is provided in one piece of the display unit 2 occupying most of the area. The size of the display unit 2 is determined according to the application, and the display unit 2 and the processing unit 3 are detachable. For example, the clip-type processing unit 3 is attached to the display unit 2. You may make it comprise electronic paper EP by connecting.

The processing unit 3 includes a driver 4 that drives the display unit 2 based on image data, a communication unit (a wireless unit that performs non-contact communication in the illustrated example) 5 for data communication with the outside, image data, and the like. A memory 6 that holds data in a readable and writable manner, a processor 7 that performs various control processes according to the present invention, a battery 8 that supplies driving power for these functional means, a button that accepts user operation input such as a partial image display instruction, and the like An operation unit 9 is provided.
The communication unit 5 may be, for example, a contact type in which data communication is performed by bringing a terminal into contact or a non-contact type in optical communication using infrared rays or the like, depending on the system configuration.

Furthermore, the electronic paper EP is displayed by the driver 4 writing an image on the display unit 2 based on the image data held in the memory 6, and the processor 7 corresponding to the operation input from the operation unit 9 or the received image data. By the processing according to the above, the image to be displayed can be switched and changed, and even when the driving power of the driver 4 is removed, the display unit 2 has a function of continuously holding the image in the display state.

  Such a self-writing type electronic paper EP has fine colored particles (white particles 21 and black in the example shown in the figure) used as toner in a copying machine, as shown in FIG. The particles 22) are enclosed between a pair of front and back electrodes 23 whose surface side is transparent, and are sandwiched between a pair of front and back film substrates 24 whose surface side is transparent. An air layer is formed between the electrode layers 23 so that the colored particles 21 and 22 can freely move, and an insulating layer 25 that prevents contact with the colored particles 21 and 22 is provided on the matrix-like electrode layer 23. It has been. Note that a color display can be realized with a simple structure by using a color filter.

Then, as shown in FIG. 12 showing the operation principle of the display unit 2, the self-writing type electronic paper EP is in a state in which no voltage is applied to the electrode 23 (however, the electrode 23 is charged to the polarity at the previous driving). The negatively charged white particles 21 accumulate on the back side, while the positively charged black particles 22 accumulate on the front side. When the display unit 2 is viewed from the front side, the display unit 2 is observed. Becomes a black state. And if the electrode polarity of the required part of the matrix according to the image information which the driver 4 operates and displays based on the electronic data is reversed, the positional relationship between the white particles 21 and the black particles 22 is switched, and the display unit 2 The image information based on the contrast between the white particles 21 and the black particles 22 is displayed. By operating the driver 4 based on different electronic data, the image information displayed on the display unit 2 can be switched depending on the contrast between the white particles 21 and the black particles 22, and can be reused many times. .
Therefore, the electronic paper EP is a display recording medium that can be used like paper because it has the property of holding the image information displayed on the display unit 2 without power in addition to the property of being thin and flexible like paper. is there.

As shown in FIG. 14, the electronic paper EP is configured such that the functional parts of the processing unit 3 such as the wireless unit 5, the memory 6, and the processor 7 are detachable wireless IC tags 27 that are separate from the electronic paper display unit 2. The wireless IC tag 27 may be configured similarly to the above by attaching the wireless IC tag 27 to the electronic paper EP. In the case of a wireless IC tag, the battery may be a capacitor that holds an electromotive force from a tag reader that is a non-contact communication partner.

A particle rotation method for switching, a magnetophoresis method for switching display by moving particles by magnetism, a thin battery-driven thin liquid crystal or an EL element may be used.

Next, an image browsing system according to an embodiment of the present invention using electronic paper EP as a display device will be described.
Here, the electronic paper EP used in the embodiments described below (see FIGS. 1 and 7 to 9) executes the processing according to the present invention based on the configuration described with reference to FIGS. Therefore, the sensor 11 that detects that another electronic paper is adjacent to the sensor 11 and the position ID that indicates the positional information (in the embodiment, the position ID) for indicating the relationship between the adjacent positions is detectable by the sensor 11. A holding unit 12 is provided. Details of the sensor 11 and the position ID holding unit 12 will be described later.
The processor 7 programmed to execute the processing according to the present invention constitutes the control unit 7, and the driver 4 constitutes the writing unit 4 that causes the display unit 2 to display and hold an image based on the image data. Yes.

The image browsing system shown in FIG. 1 corresponds to another electronic paper (second electronic paper) EP2 placed at an adjacent position, with one electronic paper (first electronic paper) EP1 leading. This is an example of providing and displaying partial image data to be displayed.
In the embodiment described below, as shown in FIG. 3, the map image is divided into nine partial map images, and these partial map image data are provided to other adjacent electronic papers by non-contact communication. Display. The original map image has a size that cannot be displayed in detail unless it is a considerably large display portion, but each divided image has a size that can be clearly displayed on the display portion 2 of the electronic paper EP.

In this example, in the memory 6 of the first electronic paper EP1, all the divided partial map image data (all data), the correspondence table (relation data) corresponding to the positional relationship shown in FIG. 4, the first electronic Predetermined identification information (self ID) is stored on the paper EP1, and the memory 6 of the second electronic paper EP2 identifies itself on the second electronic paper EP2. For this purpose, identification information (self ID) set in advance is stored.
Here, the self-ID is fixedly stored in advance in the memory 6 when the electronic paper is manufactured, but the partial map image data and the correspondence table are acquired from the server 40 as necessary and stored in the memory 6. The server 40 includes a database 41 that stores data such as partial map image data and correspondence tables, a communication unit 42 that performs non-contact data communication with the communication unit 5 of electronic paper, and a control unit that performs processing such as data communication control. 43.

The sensor 11 and the position ID holding unit 12 are provided in each electronic paper as shown in FIG.
FIG. 2 shows a state in which two other electronic papers EP2 and EP3 are arranged adjacent to the reference first electronic paper EP1, and each electronic paper is a clip forming the processing unit 3. This is shown as a type having a wireless IC tag 27 of the type.
The position ID holding unit 12 of this example is configured integrally with the sensor 11, and a total of eight sensors 11 integrated with the position ID holding unit 12 are provided for one electronic paper. That is, the integrated sensors 11 and 12 are provided outward at the four corners and the center of each side of the electronic paper.

The sensor 11 of this example is an optical sensor having directivity, and the position ID holding unit 12 is a barcode that can read the held position ID by the optical sensor.
When a plurality of electronic papers are correctly arranged adjacent to each other in a grid pattern, the sensors 11 provided at the corners of the electronic paper are arranged obliquely, and therefore only from the position ID holding units 12 provided at the corners of the other electronic papers. The position ID cannot be read, and the sensor 11 provided on each side is arranged at right angles to the side, so that the position ID is only located from the position ID holding unit 12 provided on the side of the other electronic paper. The ID cannot be read.
Various known configurations may be employed such as the position ID holding unit 12 as an IC tag and the sensor 11 as a reader that reads the position ID from the IC tag.

  Referring to the example shown in FIG. 2 in more detail, the first electronic paper EP1 has eight sensors 11 each having a position ID holding unit 12 clockwise from the upper left corner (for convenience, reference numerals 1A to 8A are assigned respectively). The second electronic paper EP2 has eight sensors 11 each having a position ID holding portion 12 in the clockwise direction from the upper left corner (for convenience, reference numerals 1B to 8B are assigned respectively). The third electronic paper EP3 has eight sensors 11 each having a position ID holding portion 12 in the clockwise direction from the upper left corner (for convenience, reference numerals 1C to 8C are assigned respectively). Is provided.

  For example, with respect to the map image divided as shown in FIG. 3, the first electronic paper EP as shown in FIG. 2 is displayed with the partial map X22 displayed on the display unit 2 of the first electronic paper EP1 as a reference. When the second electronic paper EP2 is arranged adjacent to the left side of the image, the display unit 2 of the second electronic paper EP2 is adjacent to the partial map X22 in the same positional relationship as the adjacent position on the map by the processing described below. When the partial map X21 is displayed and held, and when the third electronic paper EP3 is arranged adjacent to the lower right of the first electronic paper EP, the map is displayed on the display unit 2 of the third electronic paper EP3 by the processing described below. The partial map X33 adjacent to the partial map X22 is displayed and held in the same positional relationship as the adjacent position.

Thus, in a state where a plurality of electronic papers are adjacent to each other, the sensor 11 and the position ID holding unit 12 that are in a corresponding arrangement relationship face each other, and the position ID held by the position ID holding unit 12 is read by the sensor 11. . In the example shown in FIG. 2, 8A and 4B face each other in the first electronic paper EP1 and the second electronic paper EP2, and 5A and 1C face each other in the first electronic paper EP1 and the third electronic paper EP3. The position ID is read by the sensor 11 and input to the control unit 7.
That is, due to the above-described arrangement relationship and the directivity of the sensor, for example, as shown in FIGS. 5A and 5B, when a plurality of electronic papers are correctly adjacent in a grid shape, the position ID is read. As shown in 5 (c) and 5 (d), when a plurality of electronic papers are randomly adjacent, the position ID is not read.

FIG. 4 shows a correspondence table as the relational data. Based on the position ID read by the sensor 11, a partial map to be provided to another adjacent electronic paper is specified with reference to the correspondence table.
In FIG. 4, for convenience, the position ID holding units 12 of the first electronic paper EP hold 1A to 8A as position IDs, and the other electronic papers are similarly 1 * to 8 *. An example is shown in which the position ID (* is based on each electronic paper) is held. FIG. 4 also shows partial map data provided to other electronic papers according to the positional relationship between the first electronic paper as a reference and other electronic papers adjacent thereto, corresponding to the division of the map. It is set as (X11 to X33), and each partial map data can be read by each data ID.

  Note that since the partial image corresponding to the correspondence between the two position IDs is set in advance, the partial image is not provided when the correspondence relationship between the position IDs is not set in the table. This means that even if the position ID is read in a state in which the two electronic papers are not correctly adjacent to each other, the partial images are provided to other electronic papers and are not displayed. The correct display of is ensured.

In the embodiment shown in FIG. 1, when another electronic paper EP2 is arranged adjacent to the first electronic paper EP serving as a reference for displaying and holding the partial image X22 on the display unit 2, the following processing is performed. Thus, the adjacent partial map image corresponding to the display unit 2 of the second electronic paper EP2 is displayed and held.
When the second electronic paper EP2 is disposed adjacent to the first electronic paper EP1, the sensor 11 of the first electronic paper EP1 reads the position ID from the position ID holding unit 12 of the second electronic paper EP2. The same position ID as that of the integrated position ID holding unit 12 is set in advance for each sensor 11 and managed by the control unit 7. The control unit 7 of the first electronic paper EP 1 reads the sensor 11 of its own sensor 11 that has read. Based on the position ID and the read position ID of the other party, the corresponding adjacent partial map image is specified from the correspondence table shown in FIG.

  In addition, since the adjacent relationship between the electronic papers is specified based on the position ID of the sensor 11 that has read and the position ID of the other party that has been read, the control unit 7 of the first electronic paper may further Based on the ID of the partial map image currently displayed on the display unit 2 and the adjacent relationship between the partial map images as shown in FIG. 3, the partial map image to be provided to other adjacent electronic paper is specified. It may be.

And the control part 7 of 1st electronic paper EP1 reads the specified partial map image data from the memory 6, and transmits to 2nd electronic paper EP2 by the communication part 5. FIG. This data communication is performed with the self ID set in the electronic paper, and the second electronic paper EP2 receives the transmitted partial map image data by the communication unit 5 without interfering.
In the second electronic paper EP2, the writing unit 4 drives the display unit 2 based on the received partial map image data, and writes and holds the partial map image on the display unit 2.
Therefore, when the manner of making the second electronic paper EP2 adjacent to the first electronic paper EP1 is performed, the partial map image displayed and held on the display unit 2 of the first electronic paper EP1 has the same relationship as the adjacent positional relationship of these electronic papers. The adjacent partial map images are displayed and held on the display unit 2 of the second electronic paper EP2.

  For example, as shown in FIG. 6, a large map image M of A0 version is divided into a plurality of partial map images M, and a partial map image m is displayed on one electronic paper EP serving as a reference. When other electronic paper (for example, a blank sheet state in which nothing is displayed on the display unit) is adjacent, another partial map image adjacent to the display unit of the other electronic paper is displayed and held.

In the system shown in FIG. 7, the second electronic paper EP2 adjacent to the first electronic paper EP1 displaying the partial map image on the display unit 2 operates autonomously, and the corresponding partial map image is displayed on the display unit 2. This is an example of display. In addition, the same code | symbol is attached | subjected to a part similarly to said Example, and the overlapping description is omitted.
In this example, all the partial map image data are identified and held by the data ID in the memory 6 of the second electronic paper EP2, and the second electronic paper EP2 itself stores all the partial map image data to be displayed. It is held in advance by receiving the provision from

  In this example, when the second electronic paper EP2 is disposed adjacent to the first electronic paper EP1, the sensor 11 of the first electronic paper EP1 reads the position ID from the position ID holding unit 12 of the second electronic paper EP2, and the first electronic paper EP1 The control table 7 of the electronic paper EP1 shows the correspondence table shown in FIG. 4 based on the position ID of the sensor 11 of the electronic paper EP1 that has been read, the position ID of the other party of the reading, and the partial map image displayed by itself. To identify the corresponding adjacent partial map image.

And the control part 7 of 1st electronic paper EP1 transmits data ID of the specified partial map image data to 2nd electronic paper EP2 by the communication part 5. FIG. In the second electronic paper EP2, the control unit 7 reads out the corresponding partial map image data from the memory 6 based on the received partial map image data ID, and the writing unit 4 drives the display unit 2 to display the partial map image data on the display unit 2. Display and hold the map image.
Therefore, when the manner of making the second electronic paper EP2 adjacent to the first electronic paper EP1 is performed, the partial map image displayed and held on the display unit 2 of the first electronic paper EP1 has the same relationship as the adjacent positional relationship of these electronic papers. The adjacent partial map images are displayed and held on the display unit 2 of the second electronic paper EP2.

  Here, in the example shown in FIG. 7, the correspondence table (FIG. 3) is held in the second electronic paper EP2, and the position ID of the adjacent first electronic paper on the second electronic paper EP2 side and its display are displayed. The partial map image ID may be read and the display of the partial map image on the display unit 2 based on the adjacent relationship may be autonomously performed. That is, based on what positional relationship is adjacent to the first electronic paper EP1 and which partial map image is displayed on the first electronic paper EP1, the second electronic paper EP2 is adjacent. The partial map image data is specified, and the partial map image is written in the display unit 2.

If at least two such autonomous electronic papers (second electronic paper EP2) are prepared, the adjacent partial map images are changed by moving these electronic papers alternately to change the adjacency relationship. It can be changed and displayed one after another.
For example, when viewing a large image with a large number of divisions such as 16 divisions or 25 divisions with electronic paper, it is possible to realize a manner of saying that large images are viewed sequentially through a window called electronic paper, A desired portion of a large image can be viewed with a small number of electronic papers.

The system shown in FIG. 8 is an example in which the server 40 is led to provide and display partial map image data corresponding to the second electronic paper EP2 based on the specific information acquired from the first electronic paper EP1. It is. In addition, the same code | symbol is attached | subjected to a part similarly to said Example, and the overlapping description is omitted.
