The In the present embodiment, the leaflet image storage unit 11, the display range information storage unit 15, and the attention range information storage unit 17 are separate and independent, but may be configured integrally.

[2. Basic operational effects of the first embodiment]
The flowchart of FIG. 2 shows the processing contents of this apparatus, and will be described below with reference to FIG.

First, the browsing screen providing means 12 performs processing for accepting a leaflet browsing request (step ST1).
That is, when the browsing screen providing unit 12 is accessed from a certain user terminal T via the communication network N, the browsing screen providing unit 12 accepts a browsing request for a certain flyer (a leaflet designated by the user when there are a plurality of browseable flyers). Do.
The leaflet browsing request includes the ID of the leaflet that the user wishes to browse.

When the browsing screen providing unit 12 accepts a browsing request for a certain leaflet, the browsing screen providing unit 12 acquires the image data of the leaflet corresponding to the leaflet ID included in the browsing request from the leaflet image storage unit 11, and The leaflet browsing screen is downloaded to the user terminal T that is the browsing screen source (step ST2).
For example, if the user wishes to view a leaflet with the leaflet ID “XY56”, the image data (file name “XXX.pdf”) of the leaflet corresponding to the leaflet ID “XY56” is obtained if it has not expired. Acquire and provide a browsing screen for the flyer (see FIG. 3).
Here, image data of a PDF file is assumed, but the file format of the image data is not particularly limited, and may be image data of another file format.

Thereby, the browsing screen of a leaflet as shown in FIG. 4 is displayed on the user terminal T.
On this browsing screen, icons (operation buttons) that accept various screen operations are displayed on the web browser by the description of markup languages such as HTML and interactive video files played by the browser plug-in player. For example, the “enlarge” icon is used to enlarge the flyer, the “reduced” icon is used to reduce the flyer, and the “print” icon is used to print the flyer. .
Further, the “to back side” icon is used when displaying the back side of the flyer, and the “to front side” icon is used when returning the display of the flyer to the front side.

The display range changing means 13 accepts a screen display operation on the leaflet browsing screen (step ST3), and executes a process of changing the flyer display range on the browsing screen to a part of the leaflet according to the screen display operation (step ST4). ).
For example, if the user clicks the “enlarge” icon and then moves the mouse cursor to the point of interest on the flyer and performs a screen display operation where the left button of the mouse is pressed, the part where the mouse cursor is located will be enlarged. Then, change the display range of the flyer. FIG. 5 shows an example of the browsing screen after changing the display range.

When the display range changing unit 13 changes the display range of the leaflet to a part of the leaflet, the display range information storage unit 14 stores display range information indicating the display range that is a part of the leaflet, as shown in FIG. It accumulates in the means 15 (step ST5).
For example, when a screen display operation for enlarging a flyer is performed by the user, display range information indicating the display range of the expanded flyer is accumulated in the display range information storage unit 15.
In addition, when a screen display operation for scrolling a leaflet is performed by the user during enlarged display of a part of the leaflet, if there is a state where scrolling is stopped for a predetermined time (for example, 1 second) or more, scrolling is performed. Display range information indicating the display range of the flyer on the browsing screen when stopped is stored in the display range information storage means 15.
If the user performing the screen display operation is a user registered in advance and this screen display operation is an operation after login, the user ID assigned at the time of user registration or the registration at the time of user registration Information about the user's attributes (for example, age, sex, address, zip code, etc.) is also stored in the display range information storage unit 15.

The attention range specifying means 16 analyzes, for example, all the display range information related to the flyer with the flyer ID “XY56” in the display range information stored in the display range information storage means 15 and displays the browsing screen of the flyer. The range of the leaflet that has been noticed by a user who has browsed before is specified (step ST6).
As an example, the attention range of a leaflet is specified as follows.
First, as shown in FIG. 7, for example, the attention range specifying unit 16 divides the leaflet area into squares (for example, divides the flyer area into 8 × 8 squares). Also, an index value indicating the attention level of each cell is initialized (the index value of each cell is initialized to “0”).

Next, the attention range specifying unit 16 extracts one display range information from the display range information storage unit 15 and associates the display range indicated by the display range information with the squares of the flyer.
Then, the attention range specifying unit 16 adds “1” to the index value of the cell corresponding to the display range indicated by the display range information.
For example, if the display range indicated by the display range information is (1,1)-(4,4), as shown in FIG. 8, the cells corresponding to the display range of (1,1)-(4,4) are displayed. The index value of the eye is changed from “0” to “1”.

If there is display range information that has not yet been extracted from the display range information storage unit 15, the attention range specifying unit 16 extracts one display range information, and in the same manner as described above, the display range information is displayed in the display range indicated by the display range information. “1” is added to the index value of the corresponding cell.
For example, if display range information indicating the display range (4, 4)-(7, 7) is extracted, as shown in FIG. 9, the index value of the square of (4, 4) is changed from “1” to “1”. 2 ”and the grid index value corresponding to the display range of (5,4)-(7,4) and (4,5)-(7,7) is changed from“ 0 ”to“ 1 ”. To do.
All the display range information related to the leaflet stored in the display range information storage means 15 is taken out, and the same as above until the addition of the index value of the grid corresponding to the display range indicated by the display range information is completed. Repeat the process.

Next, the attention range specifying means 16 specifies a square having a high degree of attention among the squares of the leaflet.
For example, a deviation value of the index value of each square is calculated, and a square whose deviation value is equal to or greater than a specified value (for example, deviation value “60”) is identified as a square having a high degree of attention.
In the example of FIG. 10, since the deviation value of the grid of (3, 2)-(5, 4) is equal to or greater than the specified value, the grid of (3, 2)-(5, 4) is the attention range of the user. As specified. In addition, since the index value of the (4, 4) cell in the attention range is particularly high (for example, the deviation value “65” or more), the (4, 4) cell has a particularly high attention level (hereinafter referred to as “4”). , Referred to as “high attention level range”).
When the user's attention range is specified, the attention range specifying unit 16 records attention range information indicating the attention range in the attention range information storage unit 17 as shown in FIG.

  Here, although the attention range specifying unit 16 analyzes all the display range information regarding the leaflet stored in the display range information storage unit 15 and specifies the attention range, the display range information storage unit 15 is shown. Among the display range information stored in the screen, the range of interest is identified by analyzing only the display range information related to the screen display operation of the user having the same attribute as the user whose browsing request is accepted by the browsing screen providing means 12 You may do it.

Specifically, if the user whose browsing request has been accepted is a user registered in advance, the user's registration information is acquired and the user's attributes (for example, age, sex, address, postal code, etc.) ).
For example, when the display range information related to the screen display operation of the user whose age is the same as that of the user is set to be analyzed, from the display range information stored in the display range information storage unit 15, Display range information relating to a user of the same age (for example, 40's) as the user is extracted, and the display range information is analyzed.
The display range information to be analyzed includes, for example, a changeable attribute displayed as shown in FIG. 12 when the “change attribute” icon in the browsing screen is clicked, so that the user selects a desired attribute. It can be changed easily.
For example, if the display range information relating to a user having the same gender as the user is analyzed, the user having the same gender as the user can be selected from the display range information stored in the display range information storage unit 15. The display range information related to the screen display operation is extracted, and the display range information is analyzed.

When the attention range specifying means 16 records the attention range information in the attention range information storage means 17, the attention range display means 18 acquires the attention range information from the attention range information storage means 17, and as shown in FIG. The attention range indicated by the attention area information is displayed on the browsing screen (step ST7).
FIG. 13 shows an example in which the attention range is displayed on the browsing screen of the leaflet before the screen display operation is performed (the browsing screen displaying the entire leaflet), and (3, 2) − (5 , 4) is the attention range S (range indicated by the dotted line), and the range (4, 4) within the attention range S is the high attention degree range HS (range indicated by the one-dot chain line).
Thereby, each user can confirm the range of the leaflet which many users are paying attention to.
If the user clicks the “everyone's attention spot OFF” icon on the browsing screen, the attention range S and the high attention level range HS on the browsing screen can be deleted. If the “everyone's attention location ON” icon is clicked, the attention range S and the high attention level range HS in the browsing screen can be displayed again.

When a user wishes to take out the range of a flyer that many users are paying attention to, the user clicks the “send current range” icon in the browsing screen, and the image data in the attention range is designated to the designated mobile terminal ( For example, it can be transmitted to its own mobile phone recorded in the registration information.
That is, when the user clicks the “Send current range” icon on the browsing screen, the image data transmission unit 19 acquires the image data (see FIG. 3) of the leaflet stored in the leaflet image storage unit 11. The image data of the attention range indicated by the attention area information stored in the attention area information storage means 17 is cut out from the image data, and the image data is transmitted to the designated portable terminal.
Alternatively, when the user clicks on the “flyer cutout” icon on the browsing screen and designates the range of the flyers to be taken out, the image data transmission means 19 selects the flyer image data stored in the flyer image storage means 11. Then, the image data in the designated range is cut out, and the image data is transmitted to the designated portable terminal.
Thereby, the user can see a part of a leaflet on a portable terminal.
Note that a mobile phone browser function or the like having a screen display function such as a smartphone has an advantage that the accuracy of the attention range is excellent because the screen is narrow.

  As described above, according to the first embodiment, the display range changing unit 13 that accepts a screen display operation on the flyer viewing screen and changes the display range of the flyer on the viewing screen to a part of the flyer according to the screen display operation. Display range information storage means 14 for storing display range information indicating the display range that is a part of the leaflet changed by the display range change means 13 in the display range information storage means 15, and stored in the display range information storage means 15. At least one or more display range information is analyzed, and an attention range specifying means 16 for specifying a range of a flyer that has been noticed by a user who has previously viewed the leaflet browsing screen is provided. Is configured so that the attention range of the leaflet specified by the attention range specifying means 17 is displayed on the browsing screen. Flyers can be confirmed that point, i.e., the effect capable of providing a leaflet having a communication element between users community-based obtained.

  According to the first embodiment, among at least one or more pieces of display range information stored in the display range information storage unit 15, a user whose attribute is the same as the user whose browsing request is received by the browsing screen providing unit 12 Since the display range information related to the screen display operation is analyzed, it is possible to obtain an effect that communication elements between users having high relevance can be reflected on the flyer.

  Further, according to the first embodiment, the attention range specifying unit 16 specifies a range having a particularly high degree of attention within the attention range of the leaflet, and the attention range display unit 18 is specified by the attention range specifying unit 16. Since a range with a particularly high degree of attention is nested and displayed within the range of interest, there is an effect that it is possible to grasp a location that many users are particularly interested in.

  Further, according to the first embodiment, the attention range indicated by the attention range information stored in the attention range information storage means 17 from the image data of the leaflet stored in the leaflet image storage means 11 or designated by the user. The image data transmitting means 19 for cutting out the image data in the specified range and transmitting the image data to the designated portable terminal is provided, so that an effect that can realize light usability like a paper flyer is obtained. It is done.

  In the first embodiment, the electronic paper surface is a flyer.
