Description

  The present invention relates to a content display device and a content display method.

  In recent years, with the spread of electronic book terminals, not only books but also the trend of digitizing content such as newspapers and magazines is accelerating. Unlike text-based books, in newspapers, especially magazines, the paper layout itself includes the topic's topicality, importance, and design as well. They are distributed as standardized electronic document files such as PDF (Portable Document Format) and JPEG (Joint Photographic Experts Group) and image files.

  However, when a content display device, such as a portable electronic book terminal, displays content that has been digitized with a paper layout, it is displayed in a reduced size so that it fits on a screen smaller than the actual paper. Visibility will be extremely reduced.

  Therefore, for example, in Patent Document 1, “the content data of the content divided into a plurality of blocks, and regarding the blocks to be displayed continuously, the position relatively obtained from the position of the previous block is set as the next block. Storage means for storing content data including position data for setting a display position, content data stored in the storage means, and position data included in the content data, to a predetermined position of a predetermined block The display control means includes a display control means for controlling the display of the content by sequentially controlling the display for each block, and a display means for controlling the display to display the content. The display control means includes a predetermined block in the content. When the display is enlarged, the content is scrolled vertically to When the block is arranged so that it is illuminated, it is judged whether or not a part of the enlarged block protrudes in the horizontal direction of the display area of the display means, and the content is scrolled in the horizontal direction. When the block is arranged so that it is referred to as a whole, it is determined whether or not a part of the enlarged block protrudes in the vertical direction of the display area of the display means. When the means and the judging means determine that a part of the enlarged block protrudes in the horizontal direction or the vertical direction of the display area, the block is set based on the data included in the content data. An information processing apparatus characterized in that it includes a deformation means for deforming has been proposed.

  Further, in Patent Document 2, “In the present invention, only the headline information that is readable from the newspaper is first displayed as electronic data in the layout on the newspaper, and the readable header information is selectively designated by the user. The article information associated with the headline information is displayed on the display device as readable display data.

JP 2004-118478 A JP 2002-236701 A

  However, in the prior art described in Patent Document 1, each block in the content is displayed only in the reference order desired by the producer. Therefore, there is a problem that the user cannot selectively browse only articles of interest from headlines and photos on paper, as in the case of browsing newspapers and magazines.

  In the prior art described in Patent Document 2, since the layout is retained only for the headline, even if the content is a complicated arrangement of photos and articles like a magazine, the photos and articles are eventually It will be viewed in a layout that excludes information such as the importance of articles and design that the conventional layout had, such as arranged neatly.

  Further, in the method of partially expanding the article in the content so that each user can visually recognize the characters, each time the user finishes reading one enlarged article, the user moves to the next article to be browsed. It is necessary to repeat reduction operation, scroll operation, and the like. In addition, when the user wants to read the article while referring to the photograph, the user is forced to perform the same troublesome operation, and the problem of losing the position of the article read immediately before is also born.

  An object of the present invention is to solve such a problem and make it easy for a user to easily see a desired location when electronic content having a layout similar to that of a newspaper or magazine is displayed. It is an object of the present invention to provide a content display device and a content display method capable of performing the above.

  In order to achieve the above object, for example, the content display device according to the present invention is based on display means for displaying content composed of a plurality of areas defined for each article or photograph, and based on a user's operation. Operation means for instructing movement, enlargement or reduction of the area displayed by the display means, position coordinates relatively obtained from positions between the plurality of areas, and position coordinates absolutely obtained from the entire area of the content Link storage control means for storing both or any one of them for each area, and an instruction from the operation means, and movement between the areas based on the position coordinates, or enlargement or reduction of the area Display control means for controlling, and the display control means controls the display displayed on the display means before the movement at the time of movement control between the areas. Display range storage means for storing the content display range, and a display for reproducing the state of the display means before movement based on the content display range stored in the display range storage means in response to an instruction from the operation means Including reproduction means.

  According to the present invention, when electronic content having a layout similar to that of a paper such as a newspaper or a magazine is displayed, a user can easily see a desired portion with a simple operation.

  Hereinafter, embodiments of a content display device and a content display method according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a diagram illustrating an external configuration example of a content display device 100 according to the present embodiment, and FIG. 2 is a diagram illustrating an internal configuration example of the content display device 100. In the following description, the content is composed of a plurality of areas defined for each article or photograph.

  As shown in FIG. 1, the content display apparatus 100 of this example includes a display unit 101, a left designation key 102-1, a right designation key 102-2, a selection key 103, an upper designation key 104-1, and a lower designation key 104. -2, enlargement key 105-1, reduction key 105-2, and reset key 106. In the following description, the left designation key 102-1 and the right designation key 102-2, the upper designation key 104-1 and the lower designation key 104-2, and the enlargement key 105-1 and the reduction key 105-2. When there is no need to distinguish between them, they are simply expressed as a left / right designation key 102, an up / down designation key 104, and an enlargement / reduction key 105, respectively.

  Further, as shown in FIG. 2, the content display apparatus 100 includes a CPU (Central Processing Unit) 200, a display control unit 201 including a display range storage unit 202 and a display reproduction unit 203, a storage unit 204, a link storage control unit 205, an operation Unit 206, operation control unit 208, communication I / F (interface) 209, and external storage medium 210, and each block excluding operation unit 206 is connected to each other via bus 211.

  The display unit 101 is a display that displays the content and the like, and uses, for example, a liquid crystal display, a plasma display, an organic EL display, a field emission display, electronic paper, or the like. The left / right designation key 102, the up / down designation key 104, and the selection key 103 are provided below the display unit 101, and the user can select between the areas defined for each article or photo in the content displayed on the display unit 101. Used for moving, scrolling, selecting multiple items, etc. The enlargement / reduction key 105 is used when an instruction to enlarge or reduce the content displayed on the display unit 101, in other words, an area in the content, is given. The reset key 106 is used when an operation for returning the previous display content after moving between regions or when moving to a predetermined position in the content. The operation keys 102, 103, 104, 105, and 106 described above may be displayed on the display unit 101 and implemented as software when the touch panel 207 is added to the operation unit 206.

  The CPU 200 executes various processes according to programs in the memory included in the storage unit 204. The display control unit 201 is a controller that performs movement between regions, display control on the display unit 101, and the like according to an instruction from the CPU 200, and includes a display range storage unit 202 and a display reproduction unit 203 therein. The display range storage unit 202 temporarily stores the display state of the display unit 101 before the movement when moving between areas in response to an instruction from the operation unit 206. In response to an instruction from the operation unit 206, the display reproduction unit 203 reads the content stored in the display range storage unit and shapes the display data that can be identified by the display control unit 201. The storage unit 204 is a memory configured to include a ROM (Read Only Memory) and a RAM (Randam Access Memory).

  The link storage control unit 205 constructs a list structure indicating the relationship between regions based on link information between regions included in the content. The operation unit 206 is an interface unit that accepts user operations, and uses the operation keys, the touch panel 207, and the like described above. The operation control unit 208 is a driver that controls the operation unit 206, and outputs a signal based on the operation received by the operation unit 206 to the CPU 200. A communication I / F 209 is an external interface for connecting to a network such as the Internet, and is used for downloading contents. The external storage medium 210 is a recording medium such as a hard disk, an optical disk, or a semiconductor memory, and is used for reading or writing data.

  FIG. 3A is a diagram illustrating an example of a data structure when content displayed by the content display device 100 is an image file. The image content data 400 is divided into header information and image data information. The content of the content is stored in the image data information using JPEG format, PNG (Portable Network Graphics) format, GIF (Graphics Interchange Format), or the like. In the header information, area definition information indicating areas of photographs and articles, and inter-area link information indicating connection relations between areas are stored.

  A description example of the header information is shown in FIG. In addition, in showing a description example, an example of corresponding content is shown in FIG. This content example is assumed to be a fashion magazine mainly composed of photographs, and each element such as a title, a photograph represented by the photograph 402, and an article represented by the commentary text 403, etc. Consists of. In the example of FIGS. 3 and 4, the reference numerals common in FIGS. 3 and 4 are the same coordinates so that the coordinates 402a in FIG. 3 correspond to the region start coordinates 402a of the photograph 402 in FIG. Is expressed. In the following, an example of description for realizing the region definition of the photograph 402 and the explanatory text 403 shown in FIG.

  First, in the area definition information, identifier information 401, area start coordinates 402a, area end coordinates 402b, and area base point coordinates 402c are described in this order. In the example in the figure, each coordinate is defined based on the origin of the image content data 400. However, each coordinate may be defined by providing a different base point. The area where the photograph 402 is displayed is determined by the area start coordinates 402a and the area end coordinates 402b. The area base point coordinate 402c is used as a point that is referred to when display control is performed on the display unit 101, or a reference point when expressing in-area coordinates (however, the area base point coordinate 402c may be omitted). .

  Further, identifier information 401 defined in the area definition information and base point coordinates 403c of the connection destination are described as inter-area link information. The description text 403 is described in the same manner, so that the region definition and the interconnection relationship between the photograph 402 and the description text 403 are described. In the above example, the region definition information and the inter-region link information are divided and described. However, the inter-region link information may be added to each line of the region definition information and may be combined as header information. In addition, if there is information necessary for other processing, it may be appropriately added to the header information.

  FIG. 5 is a diagram illustrating an example of a data structure when the content displayed by the content display apparatus 100 is an electronic document file. Data of photographs and articles in the electronic document content data 500 are collected as object data. For example, the photograph data is described in the object to end object in FIG. By adding identifier information and inter-region link information 501 in the object, a link between regions can be described. If there is other information necessary for processing, it may be added to the object as appropriate.

  The content display apparatus 100 having such a configuration and the content drawing process in the content data structure will be described.

  FIG. 6 shows a flow of drawing content on the display unit 101. First, the CPU 200 reads content data from the storage unit 204 or the external storage medium 210 (S1). Next, when the content data is an image file, the link storage control unit 205 extracts area definition information and inter-area link information from the header information of the read data, constructs a page structure list described later, If the data is an electronic document file, identifier information and inter-area link information are extracted from a predetermined area in each object, and a page structure list is constructed (S2).

  Finally, the display control unit 201 shapes the content data to be displayed (S3) and displays it on the display unit 101 (S4). In displaying, it is desirable to add an automatic enlargement function for displaying on the display unit 101 according to the size of each area. Thus, the content drawing process is completed.

  In the following, an embodiment for constructing (S2) the page structure list is shown. FIG. 7A shows an example of a structure 700 for constructing a page structure list. When the content data is an image file, the position coordinate storage area 701 stores area start coordinates, area end coordinates, area base point coordinates, and the like.

  When the content data is an electronic document file, identifier information and the like are stored in the position coordinate storage area 701. If there is other necessary information, it may be added to the position coordinate storage area 701 as appropriate. Also, a left pointer storage area 702 corresponding to the left designation key 102-1, a right pointer storage area 703 corresponding to the right designation key 102-2, and an upper pointer storage area 704 corresponding to the upper designation key 104-1. , A downward pointer storage area 705 corresponding to the downward designation key 104-2, and an annotation pointer storage area 706 for designating an annotation area of a photograph or article, each of which stores a pointer corresponding to each key being pressed. Refer to the area and move between areas.

  When adding or deleting other functions, the number of pointer storage areas may be increased or decreased. If there is no reference destination, NULL or the like is stored.

  FIG. 7B is an example of a page structure list constructed by the structure 700. The image a709 has a structure in which an image annotation 708 and an article a related to the image a are attached. In addition, the image b 710 is arranged in the same hierarchy as the image a 709 and has a hierarchical structure in which both areas are directly connected. In addition, although related images and articles can be combined into a complicated nested structure, the following description will be given using FIG. 7B which is a simple hierarchical structure.

  In this example, when the user designates an image a709 as an object to be displayed by the display unit 101 (hereinafter referred to as “display object”), when the right designation key 102-2 is pressed, the display object is an image b710. Changes to. Similarly, when the lower designation key 104-2 is pressed, the display target is changed to the article a711, and when the upper designation key 104-1 is pressed, the display state is moved to the initial state 707. The initial state in this case is the state of the display unit 101 before the operation keys except the reduction / enlargement key 105 are pressed after the content drawing process is completed. At this time, if the content displayed on the display unit 101 is enlarged or reduced, an area movement process described later may be applied.

  However, the definition of the initial state is arbitrary. For example, the entire content may be displayed on the display unit 101. In the above-described transition operation between structures, it is desirable that the display unit 101 adds processing such as enclosing the area stored in the currently designated structure with a cursor so that the user can clearly indicate the operation.

  In this example, only one structure is moved from the initial state 707. This is an example for designating the browsing order intended by the content creator, and the reference destination and the operation key assignment from the initial state may be arbitrarily set. In this example, an image annotation 708 is set as the caption of the image a 709, and can be referred only through the pointer stored in the annotation pointer storage area 706. Since the image annotation 708 is extremely rarely referenced from other than the image a, the image annotation 708 has a structure that cannot be moved from other than the image a.

  Further, in this example, the destination of movement from the initial state 707 is the image a 709. However, when applied to content mainly composed of articles, for example, the hierarchical structure of images and articles is reversed, and the destination of movement from the initial state 707 is Can be directly referred to as article a711.

  In addition, when a touch panel, a mouse, or the like is used as the input I / F (in the case of the content display device 100, the touch panel 207 in the operation unit 206), each area can be directly referred to from the initial state 707. The following figure is applied (described later in Example 2). In the above example, pointers are used to move structures. However, an identifier may be provided for each structure, and movement between structures may be realized using a state transition table based on this identifier.

  If the position coordinate storage area 701 of the reference destination is invalid data, it is moved to the initial state 707 or the position coordinates stored in the area movement process described later. However, when there are a plurality of position coordinates stored in the area movement process, the position coordinates selected by the user are moved.

  The area display processing in the content display device 100 having the above configuration and the content data structure will be described.

  FIG. 9 shows an area moving process when moving between areas. First, after the above-described content drawing process is completed, when a key serving as a trigger such as the selection key 103 is input, the process proceeds to a display range saving process (T1). More specifically, the display control unit 201 performs a display range storage process (T2, which will be described later), shapes content data to be displayed (S3), and displays it on the display unit 101 (S4).

  The display range saving process (T2) is realized as follows. FIG. 10 shows an example in which an enlarged image is displayed by the content display device 100 (the following processing is also applied to the case where the article area and other areas are enlarged / reduced). In this case, arbitrary vertex coordinates 902 in the screen and coordinates 901 existing on the diagonal are temporarily stored in the storage unit 204 or the like. The coordinates to be stored are absolute coordinates obtained from the entire content, or relative coordinates in the area based on the area base point coordinates, the end points of the area, and the like. By saving these two points, the display range saving process is completed.

  As another method, the display range storage process (T2) is realized as follows. Arbitrary vertex coordinates 900 on the screen and coordinates 902 existing on the same side are temporarily stored in the storage unit 204 or the like. The coordinates to be stored are absolute coordinates obtained from the entire content, or relative coordinates in the area based on the area base point coordinates, the end points of the area, and the like. In addition to this, by providing screen size acquisition means for acquiring the screen size of the display unit 101, the display range storage processing is completed by storing the two points.

  Furthermore, as another method, the display range storage process (T2) is realized as follows. The center coordinates 903 of the screen and the magnification rate of the currently displayed content are temporarily stored in the storage unit 204 or the like. The coordinates to be stored are absolute coordinates obtained from the entire content, or relative coordinates in the area based on the area base point coordinates, the end points of the area, and the like. By saving the one point and the enlargement ratio, the display range saving process is completed.

  When a plurality of pieces of information are saved in the display range saving process, it is desirable to store the information as a free list structure so that a stack operation and a selection operation are easy.

  The content display device 100 having the above configuration and the display reproduction process in the content data structure will be described.

  FIG. 11 shows display reproduction processing when moving between regions. First, after a region moving process is performed, when a key serving as a trigger such as the reset key 106 is input, the process proceeds to a display reproduction process (U1). In the display reproduction process, the display control unit 201, more specifically, the display reproduction unit 203 specifies the display range based on the position coordinate information stored in the display range storage process (T2) described above, and displays the display range. The content data to be formatted is shaped (S3) and displayed on the display unit 101 (S4). Thus, the display reproduction process is completed.

  However, when there are a plurality of position coordinates stored in the area movement process, a display reproduction process of information specified by the user is performed.

  In this embodiment, a content display device that uses a touch panel, a mouse, or the like as an input I / F and a content drawing process will be described. In the present embodiment, the description of the page structure list, flowcharts, and the like that are the same as those in the first embodiment will be omitted.

  FIG. 8 shows an example of construction of a page structure list (S2) when a touch panel, a mouse, or the like is used as the input I / F. In this case, unlike the case where the transition between the structures is realized by the operation key, the user can directly specify each area. Therefore, it is necessary to enable bidirectional movement from the initial state 707 to all areas. Don't be.

  Accordingly, when the content data is an image file, it is determined in which area the coordinates specified by the user are included by conditional branching determined from each area range, and the specified area is specified. If it can be identified, a process of moving from the initial state 707 to each area is added. If the content data is an electronic document file, the function moves from the initial state 707 to each region using a function for selecting a specified region from specified coordinates.

  Bidirectional movement is possible by adding a pointer area indicating the initial state 707 to the structure 700 indicating each area and storing the pointer. Even in this case, it is desirable to hold each pointer storage area in the structure 700 so that it can be operated by an operation key virtually arranged in the touch panel. With the structure 700, the page structure list shown in FIG. 8 can be constructed.

  As described above, according to the content display device 100 or the content display method of the present embodiment, the CPU 200 reads the content data stored in the storage unit 204 or the external storage medium 210 and stores it in a predetermined area of the content data in advance. A page structure list is generated from the stored area definition information and link information between the areas, and information in the page structure list is read out, thereby realizing article area and photo area definitions and movement between the areas.

  Further, in the area movement process called by a specific operation, the state displayed on the display unit 101 is stored by storing the coordinates of the feature points and the enlargement ratio on the display unit 101 before the movement when moving between the areas. Remember. Similarly, the display reproduction process invoked by a specific operation reproduces the state of the display unit 101 immediately before the area movement process based on the coordinates of the feature points and the magnification rate information stored in the area movement process.

  Therefore, according to the content display device 100 or the content display method of the present embodiment, since the connection relation of the areas in the content can be expressed by the created page structure list, related images and articles are nested, etc. A complicated structure can be realized, and a user can selectively select a photo or an article, or can be displayed in a reference order desired by a content creator.

  Further, even when the area is moved by the area movement process and the display reproduction process, the state of the display unit 101 immediately before the movement can be maintained. For example, if you want to read a commentary article on a photo while comparing it with a photo, or if you are referring to a chart outside the area in the article, even if you frequently move between the picture and the chart area from the article area, read it immediately before The chance of losing the position of an article that was out is extremely low.

  Further, when the content is electronic document content data, only the identifier information and the link information are stored in each object in the electronic document data, and there is an advantage that the work amount on the content producer side is small.

  Moreover, even if the display screen of the display unit 101 is relatively small, it is easy to switch the display target, so that the user can selectively display a photograph that he wants to see and an article he wants to read.

  Moreover, even if the content has the same layout as that of a paper such as a newspaper or a magazine, an article or photo can be enlarged and displayed by a simple operation by the user.

  Furthermore, the content producers such as newspapers and magazines can effectively provide electronic newspapers and magazines having the same design and amount of information as the paper without changing the produced content.

  In addition, this invention is not limited to said embodiment, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. In addition, a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of a certain embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  Further, for example, part or all of the above-described configurations, functions, processing units, and the like may be realized by hardware such as an integrated circuit. Moreover, you may implement | achieve part or all of said each structure, a function, a process part, etc. with software, when a computer interprets and executes the program which implement | achieves each function.
