  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In the first and second embodiments, when a content described in a description language (for example, HTML, XML (extensible Markup Language) that is a structured description language) is displayed, a target portion (content portion) in the content is displayed. In this case, for example, image data) is highlighted by giving a decoration for emphasis surrounding the target portion.

[First Embodiment]
The apparatus configuration of the annotation display apparatus according to the first embodiment of the present invention will be described with reference to FIG.

  The annotation display device 1 in FIG. 1 indicates the target location in the content to be emphasized according to the description information indicating the location to be highlighted (that is, the location to be highlighted) stored in the storage device (for example, the disk device 1c). Emphasis is displayed by enclosing with an outer frame that is a highlight decoration. For example, the display is as shown in the highlighted display C of the display screen W in FIG.

  The device configuration of the annotation display device 1 in FIG. 1 includes a control unit 1a that controls each unit, a storage unit 1b that manages a storage area in a storage device (for example, a memory) provided in advance, and stores and manages data permanently. A display unit 1d including a disk device 1c, a display device, etc., a communication unit 1e for controlling communication based on a network protocol, and an operation unit 1f including an interface device (for example, a pointing device or a keyboard device) for designating a highlight display target portion. It is. The annotation display device 1 is, for example, a computer. The annotation display device 1 is connected to the web server device 2 via the network 100. The control unit 1a may include a CPU (Central Processing Unit) and an OS (Operating System) that execute a program that executes and controls each unit.

  In addition, the control unit 1a includes a target location dimension acquisition unit 1g1, a target target location size calculation unit 1g2, and a content editing unit 1g3.

  The target location dimension acquisition unit 1g1 acquires the size at which the target location is displayed as the target location size.

  The target target part size calculating means 1g2 subtracts the dimension of the emphasis decoration from the target part dimension so that the size of the target part after the emphasis decoration becomes equal to the target part dimension, and then corrects the target part size (target (Target location dimension) is calculated.

  The content editing unit 1g3 converts the target portion of the content to have a target target portion size, and remakes the content with emphasis decoration on the target portion.

  Next, a process of highlighting an arbitrary target portion in the first embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing a process of highlighting an arbitrary target portion. In the following description, descriptions of the same reference numerals as those in FIG. 1 are omitted. It is assumed that the highlight display target portion is designated in advance by the operation unit 1f. For example, the highlighted portion to be highlighted is designated by the operation unit 1f for the displayed highlight target content, and a description (hereinafter, emphasized portion instruction description; details will be described later) indicating the designated highlight display target portion is stored. It is stored in the device 1c.

  First, the emphasis target content is acquired from the web server 2 via the network 100 according to the emphasis location instruction description stored in the storage device (disk device) 1c (S101).

  The emphasis location instruction description is a description in which information necessary for emphasizing an emphasis display target location is collected. The emphasis location instruction description will be described with reference to FIG. The highlighted location instruction description (emphasized location information) includes an ID (Identifier) (ie, highlighted display management ID E11) assigned to manage the highlighted location, and an enhanced target to which the highlighted location is added. The data component includes a reference (URI) corresponding to the content (that is, highlighting target URI E12) and a position to be added in the highlighting content (that is, highlighting target position (target position) E13). The highlight display target position E13 in FIG. 4 is described in the XPPointer format. XPPointer is a standard format for designating a predetermined position in content.

For example, the position information of the first data item in FIG. 2 can be described as follows.
“#Element (/ html / body / p [2] / h1 [1])”
In the description of the position information described above, an annotation is added to the first h1 element in the child elements of the second p element among the child elements of the body element that is a child element of the html element of the HTML document. It is shown that. In the present embodiment, XPointer is used, but it goes without saying that it can be replaced with a format having a function that can specify the position in the emphasis target content.

  Next, the target part dimension acquisition unit 1g1 identifies the highlight display target part specified by the highlight display target position, acquires the target part dimension from the highlight target content, and stores it in the storage unit 1b (S102).

Next, the target target dimension calculation means 1g2 is a target value for correcting the dimension of the highlight target part so that the layout of the highlight target content does not change even if the highlight target part is surrounded by a frame. A target target part size is calculated and stored in the storage unit 1b (S103). More specifically, the dimensions are changed to the target target part dimensions obtained by the following calculation formula.
Target location size (width) = Target location size (width)-Outer frame width x 2
Target location size (height) = Target location size (height)-Outer frame width x 2
Note that the width of the outer frame is set in advance.

  In the above formula, the target target part dimension is a value obtained by subtracting the dimension of highlighting (decoration for emphasis) (for example, a value obtained by doubling the width of the outer frame from the target part dimension).

  Next, the content editing unit 1g3 generates a correction highlighting display target portion by reducing the highlight display target portion so as to have the target target portion size, and stores it in the storage unit 1b (S104).

  Next, the content editing unit 1g3 generates content (hereinafter referred to as corrected content) that has been corrected so as to display an outer frame around the correction emphasis target portion, and stores the content in the storage unit 1b (S105).

  Then, the content editing unit 1g3 generates a display screen image based on the correction highlight display target portion and the corrected content, and displays it on the display unit 1d (S106).

  Needless to say, browsing software (for example, a web browser) may be used as means for generating the display screen image. For example, the content editing unit 1g3 generates HTML (display screen image) data in which the corrected content is embedded at a location according to the correction highlight display target location in the highlight target content, and the embedded HTML data is transmitted to the web browser. Via the display unit 1d.

  As described above, in the first embodiment, for example, when interesting information is found in a part of a certain content and the information is to be transmitted to an acquaintance, information indicating the highlighted portion and the corrected content are transmitted to the acquaintance by e-mail or the like. Thus, the acquaintance can browse the content in which the information is highlighted, and can further easily identify the location.

  As an example of the first embodiment, an example in which text is highlighted will be described. In this embodiment, the text character size is set by describing it in an HTML document.

  More specifically, in step S104 of FIG. 3, instead of generating a target location that is reduced to fit the target target location size, HTML is generated so that the text that is the target location becomes the target target location size. Describes the text size setting for the document.

For example, it is assumed that the HTML document to be emphasized is the following document 1.
Document 1 “It is necessary to create new services to improve sales.”
The character size is appropriately changed by giving the following setting (setting by the font tag) in the document 1. That is, when emphasizing “new service”, the following setting is given in accordance with the target target part size (height) calculated in step S103.
Document 2 “<font size =“ target target part size (height) ”> creation of a new service </ font> is necessary to improve sales.”
By giving the setting as described above, the character size is appropriately changed.

  In the present embodiment, a method of correcting an HTML document and changing a character size has been described, but it goes without saying that any equivalent effect can be expected, such as using CSS (Cascading Style Sheets).

[Second Embodiment]
The second embodiment is an annotation display system composed of a server device and a client device. Needless to say, the server application and the client application may be executed on the same computer.

  The configuration of the annotation display system in the second embodiment will be described with reference to FIG.

The server device 3 is a typical web server, and appropriately includes an application server and a database system. Basically, the server apparatus 3 receives an HTTP (Hyper Text Transfer Protocol) request from the client apparatus 4 via the network 100 and transfers a predetermined document to the client apparatus 4. Alternatively, an argument included in HTTP is passed to a predetermined program, and the return value is transferred to the client device 4.

  The device configuration of the server device 3 in FIG. 5 includes a control unit 3a that controls each unit, a storage unit 3b that manages a storage area in a storage device (for example, a memory) provided in advance, and stores and manages data permanently. A disk device 3c is a communication unit 3d that controls communication based on a network protocol.

  The device configuration of the client device 4 in FIG. 5 includes a control unit 4a that controls each unit, a storage unit 4b that manages a storage area in a storage device (for example, a memory) provided in advance, and stores and manages data permanently. A display unit 4d including a disk device 4c, a display device, etc., a communication unit 4e for controlling communication based on a network protocol, and an operation unit 4f including an interface device (for example, a pointing device or a keyboard device) for designating a highlight display target location. is there. The control units 3a and 4a may include a CPU (Central Processing Unit) and an OS (Operating System) that execute a program that executes and controls each unit.

  Moreover, the control part 3a is provided with the target location dimension acquisition means 3e1, the target target location size calculation means 3e2, and the content edit means 3e3 similarly to 1st Embodiment. That is, the server device 3 may be considered as an annotation display (server) device.

  A process of highlighting a target portion in the annotation display system of the second embodiment will be described with reference to FIG. In the following description, the same reference numerals as those in FIG. 5 are omitted.

  First, the communication unit 4e of the client device 4 transmits an HTTP request to the communication unit 3d of the server device 3 (S201). The HTTP argument includes a highlight target URI (or highlight management ID). It goes without saying that the HTTP argument may include the highlight target URI and the highlight management ID at the same time.

  Next, the control unit 3a of the server device 3 acquires the highlighted display target URI (or highlighted display management ID) included in the received HTTP request (S202). Further, the content to be emphasized (emphasis target content) is acquired from the web server 5 corresponding to the highlight display target URI.

  Next, with reference to the highlight database stored in the disk device 3c, a highlight data set that satisfies the highlight target URI or the highlight management ID is acquired (S203).

  The highlight database and the highlight data set will be described. The highlight data set includes a unique ID (ie, highlight management ID 21) assigned to manage each highlight location, and the URI of the content to be highlighted to which the highlight location is to be added (ie, highlight display target URI). E22) is a data set having a position to be added in the target content (that is, highlighted display target position E23) as a data component. The highlight database is, for example, a database having a plurality of highlight data sets as shown in FIG.

  Next, the target part dimension acquisition means 3e1 specifies the highlight display target part designated by the highlight display target position, acquires the target part dimension, and stores it in the storage unit 3b (S204).

Next, the target target dimension calculation means 3e2 is a target value for correcting the dimension of the highlight target portion so that the layout of the highlight target content does not change even if the highlight target portion is surrounded by a frame. The target target part size is calculated and stored in the storage unit 3b (S205). Specifically, it is changed to a correction value obtained by the following calculation formula.
Target location size (width) = Target location size (width)-Outer frame width x 2
Target location size (height) = Target location size (height)-Outer frame width x 2
Note that the width of the outer frame is set in advance.

  In the above formula, the target target part dimension is a value obtained by subtracting the dimension of highlighting (decoration for emphasis) (for example, a value obtained by doubling the width of the outer frame from the target part dimension).

  Next, in the first embodiment, reduction is performed so that the highlight target location becomes the target target location size. However, in the second embodiment, the content editing unit 3e3 highlights the target target location size. The target part is cut (cut), and only a part is generated as a correction highlight display target part, and stored in the storage unit 3b (S206). It should be noted that any part of the highlighting target part to be cut may be cut as long as the correction highlighting target part satisfies the target target part size.

  Next, the content editing unit 3e3 generates content that is corrected so that an outer frame is displayed around the correction emphasis target portion (hereinafter referred to as corrected content), and stores it in the storage unit 3b (S207).

  Next, the corrected content is transmitted to the client device 4 (S208).

  Then, based on the corrected content document received from the server device 3, a display screen image is generated and displayed on the display unit 4d (S209). Needless to say, browsing software (for example, a web browser) may be used as means for generating an image of the display screen in step S209.

  As described above, according to the second embodiment, for example, when interesting information is found in a part of a certain content and the information is to be transmitted to an acquaintance, the information indicating the highlight target portion is registered in the server. Teach registered highlight management ID. By transmitting the highlight management ID to the server, the acquaintance can browse the content in which the target information is highlighted, and can easily identify the location.

  Note that some or all of the functions of each means in the annotation display device of the first embodiment and the annotation display system of the second embodiment are configured by a computer program, and the program is executed using the computer to execute the present invention. Needless to say, the method (procedure) related to the annotation display device of the first embodiment and the annotation display system of the second embodiment can be configured by a computer program, and the program can be executed by the computer.
