FIG. 2C is a diagram illustrating an example of functional blocks in the system control unit 14 or the system control unit 26. In the content display process, the system control unit 14 (processor in the system control unit 14) or the system control unit 26 (processor in the system control unit 26), as shown in FIG. , Functioning as an estimated exposure time determination unit 102, an interest degree calculation unit 103, an information amount update unit 104, a display control unit 105, and the like. The target content specifying unit 101 is an example of specifying means in the present invention. The estimated exposure time determination unit 102 is an example of a determination unit in the present invention. The interest level calculation unit 103 is an example of calculation means in the present invention. The information amount update unit 104 is an example of a changing unit in the present invention. The display control unit 105 is an example of display control means in the present invention.

When the page is displayed on the display screen of the client terminal 2, the target content specifying unit 101 specifies the content that is not displayed in the display screen among the contents in the content display area arranged on the page as the target content. . When there are a plurality of contents that are not displayed on the display screen, each content may be specified as the target content, or any one of the plurality of contents (for example, the earliest display on the display screen) Content placed at a position) may be specified as target content.

The estimated exposure time determination unit 102 determines that the target content that is not displayed in the display screen is displayed in the display screen in response to an operation (for example, a scroll operation, a page down operation, or a page up operation) of the page viewer. Estimated exposure time estimated to be displayed in is determined. This estimated exposure time is from the time the target content not yet displayed in the display screen appears in the display screen (that is, after frame-in) until it goes out of the display screen (disappears) (that is, Indicates the estimated time length (to frame out). For example, the estimated exposure time determination unit 102 displays the speed at which the page changes according to the operation of the page viewer (for example, the change speed such as the scroll speed) and the display screen size (that is, the display in the change direction such as the scroll direction). The estimated exposure time is determined based on the screen size). Thereby, it is possible to determine the estimated exposure time with high accuracy that matches the actual exposure time.

FIG. 3 is a diagram showing an example of the relationship between the page and the display screen when the page scrolls. In the example of FIG. 3, it is assumed that the contents C1 to C18 are arranged (arranged in the respective content display areas) on the page, and among these, the content C5 is specified as the target content. In the example of FIG. 3A, the target content C5 is not displayed in the display screen, and in the example of FIG. 3B (future time point), the target content C5 appears and is displayed in the display screen. In the example of FIG. 3C (future time), the target content C5 is out of the display screen. Here, the scroll speed of the page (for example, an average value, a maximum value, or a minimum value may be Xmm / second), and the size of the display screen in the scroll direction (vertical size in the example of FIG. 3) is Ymm. Then, the estimated exposure time is calculated as a value obtained by dividing the size Y of the display screen by the scroll speed X. Thus, the estimated exposure time can be grasped as an integrated amount while the target content C5 is exposed. The estimated exposure time can also be said to be a time during which the viewer's interest in the target content C5 can be maintained.

Note that the estimated exposure time determination unit 102 is a duration in which other content different from the target content (for example, content C2 shown in FIG. 3A) is displayed in the display screen according to the operation of the page viewer. The estimated exposure time may be determined by specifying. This duration indicates the time during which the other content is actually displayed in the display screen (that is, the measurement time length from when the other content appears in the display screen until it goes out of the display screen) According to this determination method, it is possible to determine an estimated exposure time with high accuracy that matches the actual exposure time, and other content different from the target content may be content highly related to the target content. For example, examples of other content include content including a keyword common to or related to the target content, content including a tag common to or related to the target content, content belonging to a category or genre common to or related to the target content, and the like. It is done.

Further, the estimated exposure time determination unit 102 may determine the estimated exposure time to be shorter as the degree of interest in the target content of the page viewer is higher. Thereby, the estimated exposure time for more effective presentation of the target content can be determined. This is to reduce the amount of information of the target content by shortening the estimated exposure time as the degree of interest of the viewer in the target content increases. As a result, it is possible to present target content that is easily noticed by the viewer (in other words, easy to grasp at a glance). In this case, the degree-of-interest calculation unit 103 acquires, for example, the preference information of the viewer of the page from the user information management server 3 (obtained using the user ID of the viewer as a key), and based on the acquired preference information The interest level of the viewer for the content is calculated. For example, the interest level calculation unit 103 searches the information included in the target content for the product category, current affairs, or genre indicated by the viewer's preference information, and the higher the number of hits in the search, the more the viewer The degree of interest of is calculated high. For example, when the hit number is 0, the interest level is 1, and when the hit number is 1 or more and less than 5, the interest level is 2, and when the hit number is 5 or more and less than 10, the interest level is calculated as 3. Is done. In this case, for example, the estimated exposure time determination unit 102 decreases the coefficient as the degree of interest increases (for example, the coefficient is 1 when the degree of interest is 1, the coefficient is 0.9 when the degree of interest is 2, When the degree of interest is 3, the estimated exposure time is determined (that is, corrected and finally determined) by multiplying the estimated exposure time determined (provisionally determined) by 0.8).

In addition, the estimated exposure time determination unit 102 is another content that is displayed earlier than the target content, and the other content with a relatively high degree of interest of the viewer and the position of the target content are close to each other. You may determine so that estimated exposure time becomes short, so that (distance is short). Thereby, the estimated exposure time for more effective presentation of the target content can be determined. This is to reduce the amount of information of the target content by shortening the estimated exposure time as the position on the page of the other content with relatively high interest and the target content is closer. As a result, even if other content with a relatively high degree of interest of the viewer is displayed first, it is possible to present target content that is easily noticed by the viewer. In this case, the interest level calculation unit 103 acquires, for example, the preference information of the viewer of the page from the user information management server 3, calculates the interest level of the viewer with respect to the target content based on the acquired preference information, And the interest degree of the said viewer with respect to the other content displayed ahead of the said target content is calculated. The method of calculating the degree of interest in this case is the same as described above. Then, for example, the estimated exposure time determination unit 102 compares the interest level of the viewer with respect to the other content and the interest level of the viewer with respect to the target content, and the interest level of the viewer with respect to the other content is determined as the target content. Is greater than (or higher than) the interest level of the viewer, the coefficient (for example, the smaller the distance on the page between the other content and the target content (for example, the distance between the center coordinates of each content display area)) When the distance is less than 1, the coefficient is 0.8, when the distance is 1 or more and less than 2, the coefficient is 0.9, and when the distance is 2 or more and less than 3, the coefficient is 1). The estimated exposure time is determined (corrected) by multiplying the time.

In addition, when there are a plurality of other contents to be displayed before the target content, the degree of interest of the viewer with respect to each of the other contents is calculated, and the degree of interest of the viewer among the plurality of other contents is calculated. For example, the highest other content is selected. In this case, the estimated exposure time determination unit 102 compares the viewer's interest in the selected other content with the viewer's interest in the target content, and the viewer's interest in the selected other content. If the degree of interest is greater than or equal to the viewer's interest in the target content (or higher), a coefficient that decreases as the distance on the page between the selected other content and the target content decreases is determined as the estimated exposure time determined above. The estimated exposure time is determined (corrected) by multiplying by. Alternatively, when there are a plurality of other contents to be displayed before the target content, the estimated exposure time determination unit 102 determines the viewer's interest in each other content and the viewer's interest in the target content. Are compared, and when the percentage of the viewer's interest in other content is greater than or equal to (or higher) the viewer's interest in the target content, You may determine (correct | amend) so that the estimated exposure time of the said target content may be shortened, so that the distance on the page of a content is short (that is, the display position of the said some other content is fixed). In addition, you may comprise so that estimation exposure time may be correct | amended according to the magnitude of relative interest degree about several other content with a close display position.

Regardless of whether the viewer is highly interested, the estimated exposure time determination unit 102 increases the estimated exposure time as the number of other contents displayed in the display screen at the same time as the target content increases. You may determine so that it may become short. Thereby, the estimated exposure time for more effective presentation of the target content can be determined. This is to reduce the amount of information of the target content by shortening the estimated exposure time as the number of other contents displayed on the display screen at the same time as the target content increases. As a result, it is possible to present target content that is easily noticed by the viewer among many displayed contents. In this case, the estimated exposure time determination unit 102 selects other content that is located within a predetermined range (for example, a range corresponding to the size of the display screen) centered on the target content (for example, the center coordinates of the content display area are located). Calculate the number. Then, the estimated exposure time determination unit 102 is a coefficient that decreases as the number of calculated other contents increases (for example, the coefficient is 1 when the number of contents is less than 5, and the number of contents is 5 or more and less than 10). The estimated exposure time is determined (corrected) by multiplying the determined estimated exposure time by 0.9 when the coefficient is 0.9, and when the number of contents is 10 or more, the coefficient is 0.8). Note that the estimated exposure time determination unit 102 may determine that the estimated exposure time of the target content is shorter as the content display area of other content displayed on the display screen at the same time as the target content is larger. . In this case, the estimated exposure time determination unit 102 calculates the proportion of the content display area of other content in the display range. Then, the estimated exposure time determination unit 102 is a coefficient that decreases as the calculated content display area ratio increases (for example, the coefficient is 1 when the ratio is less than 10%, and the ratio is 10% or more and less than 30%). The estimated exposure time is determined (corrected) by multiplying the estimated exposure time determined above by a coefficient of 0.9 and a coefficient of 0.8 when the ratio is 40% or more.

The information amount update unit 104 updates the information amount of the target content based on the estimated exposure time determined by the estimated exposure time determination unit 102. Here, the information amount of the target content means, for example, an apparent amount of information recognized by the viewer on the display screen, and is at least one of image data and text data constituting the target content. The amount of data (data size (bytes)) may not be changed. For example, the information amount update unit 104 changes the information amount of the target content to be smaller as the estimated exposure time is shorter. In other words, the information amount update unit 104 changes the information amount of the target content to increase as the estimated exposure time increases. Accordingly, it is possible to present target content that is easily noticed by the viewer.

Incidentally, the information amount update unit 104 may change the information amount of the target content in real time according to a predetermined standard when the estimated exposure time is determined by the estimated exposure time determination unit 102. In this case, for example, the information amount update unit 104 reduces the number of characters included in the target content or reduces the image size. However, preferably, the information amount updating unit 104 sets the default target content for each content display area (area ID) (for example, for each content display area in which each of the contents C1 to C18 shown in FIG. 3 is arranged). ), The information amount of the target content is updated by selecting the target content corresponding to the estimated exposure time determined by the estimated exposure time determination unit 102 based on the exposure time correspondence information amount table created in advance. As a result, the processing load can be reduced, so that the information on the target content can be quickly updated and displayed.

FIG. 4 is a conceptual diagram illustrating an example of selecting target content corresponding to the determined estimated exposure time. In the example of FIG. 4, according to the exposure time correspondence information amount table, as shown in (A) to (D), target contents having different information amounts are associated with each of a plurality of estimated exposure time ranges. . For example, it may be defined in the structured document constituting the page so that the target content is arranged on the page as an inline frame. In the estimated exposure time range (10 seconds or more) shown in FIG. 4A, target content (for example, target content set as default) having the largest number of characters as the information amount is associated. In the estimated exposure time range (between 5 seconds and less than 10 seconds) shown in FIG. 4 (B), a predetermined character is subtracted from the number of characters of the target content shown in FIG. 4 (A) (the character size is increased accordingly). The target content is associated. In the estimated exposure time range (1 second or more and less than 5 seconds) shown in FIG. 4C, a predetermined character is further subtracted from the number of characters of the target content shown in FIG. 4B (the character size is increased accordingly). In addition, the target content whose image size is reduced is associated. In the estimated exposure time range (less than 1 second) shown in FIG. 4D, a predetermined character is further subtracted from the number of characters of the target content shown in FIG. 4C (the character size is enlarged correspondingly), and the image Is associated with the target content that is deleted (that is, the image is deleted because it may not be understood even if it is displayed at a corner). In this case, the information amount update unit 104 prepares a target corresponding to an estimated exposure time range including a determined estimated exposure time from a plurality of target contents having different information amounts prepared in advance as shown in FIG. By selecting the content and placing it on the page, the amount of information of the target content set as default is updated (when the target content set as default is selected, the amount of information of the target content is not changed).

In the example of FIG. 4, the information amount update unit 104 changes the information of the target content without changing the display size of the content display area of the target content (in this example, the number of characters is reduced, the character size is increased, the image is Reduction, image deletion). As a result, the information amount of the target content can be changed without changing the page layout, so that the information amount of the target content can be quickly updated and displayed. As another example, the information amount update unit 104 may change (enlarge or reduce) the display size of the content display area of the target content so as to match the information amount of the target content after the change. Thereby, it is possible to update to the display size of the content display area that fits the changed information amount (information amount of the target content). Further, the information amount update unit 104 may change (enlarge or reduce) the display size of the target content. Thereby, the amount of information of the target content can be quickly updated and displayed. Alternatively, the information amount updating unit 104 increases or decreases the information amount corresponding to the difference based on the difference between the reference exposure time set in advance for each target content and the estimated exposure time, thereby increasing the information amount of the target content. May be changed. In this case, for example, the information amount (for example, the number of characters and the image size) is associated with each of the difference ranges previously divided into a plurality, and the information amount update unit 104 determines the determined estimated exposure time and the reference The information amount corresponding to the difference range including the difference with the exposure time is selected, and the information amount of the target content set as default is changed according to the selected information amount.

The display control unit 105 is a target whose information amount has been updated by the information amount updating unit 104 according to, for example, the operation of the page viewer or the automatic scrolling of the page triggered by the operation of the page viewer. Display content on the display screen. FIG. 5 is a diagram illustrating an example of a display screen when the target content whose information amount has been changed is displayed. The example in FIG. 5A shows a display example of the target content C5 when the estimated exposure time determined by the estimated exposure time determination unit 102 is 6 seconds, and the example in FIG. The display example of the target content C5 when the estimated exposure time determined by the unit 102 is 0.8 seconds is shown. As can be seen from a comparison between FIGS. 5A and 5B, the amount of information decreases as the estimated exposure time is shorter. Therefore, it is possible to effectively present target content that is easily noticed by the viewer (in other words, easily grasped at first glance) while flexibly responding to the display time of the display area that changes according to the operation of the viewer. And the effect of displaying the target content can be sufficiently obtained.

[2. Operation of content display system S]
Next, the operation of the content display system S according to the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating an example of content display processing executed by the system control unit 26 of the client terminal 2. The content display process executed by the system control unit 26 is performed according to a program (script) described in the structured document of the page, for example. When the system control unit 26 of the client terminal 2 accesses the content providing server 1 and transmits a page request according to the URL of the Web site specified by the browser by the operation of the page viewer, the content providing server 1 (the Web site) ) To the client terminal 2.

When the system control unit 26 of the client terminal 2 acquires the page from the content providing server 1, it starts the content display process shown in FIG. Note that the content display process shown in FIG. 6 may be started after the user of the client terminal 2 (that is, the page viewer) is logged in by a login request from the client terminal 2 to the content providing server 1. When the process shown in FIG. 6 is started, the system control unit 26 displays the acquired page on the display screen that appears on the display (step S1).

Next, the system control unit 26 (target content specifying unit 101) specifies, as target content, dynamic content that is not displayed in the display screen among the contents in the content display area arranged on the page (step S2). At this time, when there are a plurality of dynamic contents that are not displayed in the display screen, a plurality of target contents may be specified, but in the example of FIG. 6, one specific content is specified. Note that the system control unit 26 transmits information indicating the range (for example, coordinates) of the page displayed in the display screen to the content providing server 1 so that the system control unit 14 of the content providing server 1 displays the page. Dynamic content that is not displayed in the display screen among the content in the arranged content display area may be specified as target content.

Next, the system control unit 26 determines whether or not there is an operation for changing the page by the viewer (step S3). If the system control unit 26 determines that there is no operation for changing the page by the viewer (step S3: NO), the system control unit 26 advances the process to step S4. On the other hand, if the system control unit 26 determines that there has been an operation for changing the page by the viewer (step S3: YES), the system control unit 26 advances the process to step S5.

In step S4, the system control unit 26 determines whether or not there has been an operation for terminating the display of the page by the viewer. When the system control unit 26 determines that there is an operation for terminating the display of the page by the viewer (step S4: YES), the content display process is terminated. On the other hand, if the system control unit 26 determines that there is no operation to end the display of the page by the viewer (step S4: NO), the system control unit 26 returns the process to step S3. In step S <b> 5, the system control unit 26 starts page transition (for example, scrolling) in response to an operation for shifting the page.

Next, the system control unit 26 (estimated exposure time determination unit 102) displays the target content that is not displayed in the display screen, as described above, in the display screen according to the operation of the viewer. The estimated exposure time estimated as is determined (step S6). At this time, when the browser is logged in, the system control unit 26 (interest degree calculation unit 103) acquires the browser's preference information from the user information management server 3 using the user ID of the viewer as a key. Based on the acquired preference information, as described above, the interest level of the viewer with respect to the target content may be calculated. In this case, as described above, the system control unit 26 (estimated exposure time determination unit 102) corrects the estimated exposure time, for example, as the degree of interest of the viewer in the target content increases, or from the target content. Is corrected so that the estimated exposure time becomes shorter as the position of the target content in the other content and the target content closer to each other is the other content that is displayed earlier. . Note that the system control unit 14 of the content providing server 1 may determine the estimated exposure time.

Next, the system control unit 26 (information amount update unit 104) updates the information amount of the target content as described above based on the estimated exposure time determined in step S6 (step S7). For example, the system control unit 26 (information amount updating unit 104) changes the information amount of the target content to be smaller as the estimated exposure time is shorter.

Next, the system control unit 26 determines whether or not the target content has entered (displayed) in the display screen (step S8). If the system control unit 26 determines that the target content has entered the display screen (step S8: YES), the system control unit 26 advances the process to step S9. On the other hand, when the system control unit 26 determines that the target content is not included in the display screen (step S8: NO), the system control unit 26 advances the process to step S10.

In step S9, the system control unit 26 determines whether or not the page transition has been completed. If the system control unit 26 determines that the page transition has not ended (step S9: NO), the system control unit 26 returns the process to step S8. On the other hand, if the system control unit 26 determines that the page transition has ended (step S9: YES), the system control unit 26 returns the process to step S2.

In step S10, as described above, the system control unit 26 (display control unit 105) displays the target content whose information amount has been updated in step S7 on the display screen. Note that the system control unit 14 of the content providing server 1 may display the target content with the updated information amount on the display screen (for example, data indicating the updated information amount on the browser of the system control unit 26). To display the target content whose information amount has been updated in the display screen).

Next, the system control unit 26 determines whether or not the page transition has been completed (step S11). If the system control unit 26 determines that the page transition has not ended (step S11: NO), the system control unit 26 returns the process to step S11. On the other hand, when the system control unit 26 determines that the page transition has ended (step S11: YES), the system control unit 26 returns the process to step S2.

As described above, according to the above embodiment, in the content display system S, when a page is displayed on the display screen of the client terminal 2, the display screen among the contents in the content display area arranged on the page. Content that is not displayed within the target content is determined as target content, an estimated exposure time of the target content that is not displayed in the display screen is determined according to the operation of the page viewer, and based on the estimated exposure time Since the information content of the target content is updated and the target content with the updated information content is displayed on the display screen, it can flexibly handle the display time of the display area that changes according to the operation of the viewer. However, it is possible to present effective content to the viewer.
