  Next, the functional configuration of the display device 100 will be described.

  FIG. 3 is a schematic block diagram illustrating a functional configuration of the display device 100. As illustrated in FIG. 3, the display device 100 functions as a reception unit 111, a detection unit 112, a change unit 113, and a presentation unit 114.

  The accepting unit 111 accepts content including items arranged in a predetermined order. Specifically, the reception unit 111 receives, for example, a product list page including a product list as content from the content providing apparatus 200. In this embodiment, an example in which the product list page is a document described using HTML (Hypertext Markup Language) will be described. However, the product list page may be described in a markup language other than HTML.

  FIG. 4 shows an example of a product list page received by the receiving unit 111. The product list page 400 shown in FIG. 4 is a web page including information on a plurality of products sold in the electronic market. The product list page 400 includes items 410_1 to 410_N including information on products for N products (N is an arbitrary natural number). The items 410_1 to 410_N are composed of product images 411_1 to 411_N and product description sentences 412_1 to 412_N as information about the products. The items 410_1 to 410_N are displayed in a predetermined order on the product list page 400. For example, when the product list page 400 is a page displayed as a product search result, the items 410_1 to 410_N are arranged in a predetermined order in the rank order of the search result. Then, when the user selects the items 410_1 to 410_N, the user moves to the product page in which the details of the selected items 410_1 to 410_N are described.

  In the present embodiment, the control unit 101 and the communication unit 105 cooperate to function as the reception unit 111.

  The detection unit 112 detects scrolling on the screen of the display unit 104. For example, when the display area of the content displayed on the screen of the display unit 104 is moved by the presentation unit 114, the detection unit 112 detects scrolling of the content on the screen. Specifically, when the product list page 400 shown in FIG. 4 is displayed on the screen 500 of the display unit 104 as shown in FIG. The display area is located in an area including items 410_1 to 410_5. Thereafter, when the display area of the product list page 400 moves to an area including the items 410_k to 410_k + 4 as shown in FIG. 5B, the detection unit 112 detects scrolling of the product list page 400 on the screen 500.

  In the present embodiment, the control unit 101 functions as the detection unit 112.

  When the scroll detected by the detection unit 112 satisfies a predetermined condition, the changing unit 113 deletes a part of the item description of the item displayed together with the item on the screen of the display unit 104, and the remaining part of the item description The display mode of the item is changed by increasing the character size.

  The predetermined condition is, for example, a condition that the detected scroll speed is equal to or higher than a threshold value. Specifically, the change unit 113 detects the amount of change in the coordinate position of the content display area, and calculates the amount of change in the coordinate position per unit time to detect the scroll speed. Then, the changing unit 113 determines that the detected scroll satisfies the predetermined condition when the detected scroll speed is equal to or higher than the predetermined threshold.

  Further, the predetermined condition may be a condition that scrolling in the same direction has continued for a predetermined time or more, or that a touch operation instructing scrolling in the same direction from the user has been performed a predetermined number of times or more within a predetermined time. Good. Specifically, the changing unit 113, when the display area of the content displayed on the screen of the display unit 104 by the presentation unit 114 moves in the same direction for a predetermined time or more, the detected scroll satisfies the predetermined condition. Is determined. Alternatively, the change unit 113 determines that the detected scroll satisfies a predetermined condition when the touch panel unit 106 determines that a flick or slide in the same direction is received a predetermined number of times or more within a predetermined time as a touch operation. In general, a user who skips and reads information included in other items in order to reach a desired item position frequently inputs an operation for scrolling. Therefore, by setting the continuation of the scroll detected as described above as a predetermined condition, it is possible to display the item in a manner that allows the user to easily reach the item position desired by the user.

  Then, when the scroll satisfies a predetermined condition, the changing unit 113 deletes a part of the item description of the item that should appear on the screen 500 thereafter. Specifically, the changing unit 113 deletes a common part seen from other items from the explanatory text. For example, the change unit 113 refers to “beer”, “350 ml”, “500 ml”, and “[free shipping]” in the item descriptions 412_1 to 412_N of the items 410_1 to 410_N included in the item list page 400 illustrated in FIG. When it is determined that the appearance frequency of the wording is higher than a predetermined threshold value, the item description 412_1 to the item 410_1 to 410_N that should appear on the screen 500 after determining that the scrolling satisfies the condition with these words as common parts. Delete from 412_N. Further, the changing unit 113 omits a portion after a predetermined number of characters from the head of the product description 412_1 to 412_N after deleting the common portion. For example, the changing unit 113 adds a symbol “...” to the omitted part to indicate that the subsequent product description 412_1 to 412_N is omitted. Further, the changing unit 113 may leave the notation of the amount of money such as “xxxx yen” in the product description sentences 412_1 to 412_N without being omitted. Then, the changing unit 113 increases the character size of the remaining part of the product description sentences 412_1 to 412_N from a predetermined initial value.

  In the present embodiment, the control unit 101 functions as the changing unit 113.

  The presentation unit 114 displays the content on the screen of the display unit 104 in the display mode changed by the changing unit 113. Specifically, first, when the reception unit 111 receives content, the presentation unit 114 displays the content on the screen of the display unit 104 in an initial display mode. Then, the presentation unit 114 controls the display area of the content displayed on the screen based on the touch operation received by the touch panel unit 106. For example, when the presentation unit 114 determines that the touch panel unit 106 has accepted a flick or slide in a scrollable direction on the screen as a touch operation, the display unit 114 moves the content display area in the flick or slide direction. Scroll content. Here, the flick is an operation in which the finger is quickly moved by a certain distance while the finger is touched on the touch panel unit 106 and the finger is released from the touch panel unit 106 as it is. The slide is an operation for moving the finger while touching the finger on the touch panel unit 106. When the user finishes the flick and releases the finger from the touch panel unit 106, the presentation unit 114 controls the screen drawing so that the content is gradually decelerated as if the content is scrolling with inertia. Hereinafter, such a scroll that gradually decelerates is called inertial scroll. Specifically, when it is determined that the touch panel unit 106 has accepted a flick in a scrollable direction on the screen as the touch operation, the presentation unit 114 starts scrolling the content, and scrolls as time passes after the flick. Decrease the speed gradually. For example, the presentation unit 114 decreases the scroll speed based on a predetermined friction coefficient. Further, when the display mode is changed by the changing unit 113, the presentation unit 114 displays the content in the changed display mode.

  Hereinafter, display examples when the presentation unit 114 displays the product list page 400 illustrated in FIG. 4 on the screen 500 of the display unit 104 as content will be described with reference to FIGS.

  Fig.5 (a) shows the example of a display of the goods list page 400 in the display mode of an initial state. For example, immediately after the product list page 400 is received by the receiving unit 111 and when scrolling on the screen 500 is not detected, the presentation unit 114 displays the head in a predetermined order as illustrated in FIG. Items 410_1 to 410_5 are arranged in the vertical direction and displayed on the screen 500. At this time, the presentation unit 114 displays the items 410_1 to 410_5 in a display mode (hereinafter, referred to as a display mode in the initial state) in which all of the item descriptions 412_1 to 412_5 are displayed and the character size is a predetermined initial value. To do.

  FIG. 5B shows a display example of the product list page 400 when the scroll detected on the screen 500 does not satisfy a predetermined condition. After the display of FIG. 5A, in order to see the sixth and subsequent items 410_6 to 410_N that are not displayed on the screen 500, the user flicks the screen 500 upward with respect to the touch panel unit 106, for example. If it does, the detection part 112 will detect the upward scroll in the screen 500. And when the change part 113 determines with the detected scroll not satisfy | filling predetermined conditions, as shown to FIG.5 (b), the presentation part 114 is the kth item 410_k by the display mode of an initial state. , Item 410_k + 4 is displayed on the screen 500.

  FIGS. 5C and 5D show display examples of the product list page 400 when the scroll detected on the screen 500 after the state shown in FIG. 5B satisfies a predetermined condition. When the changing unit 113 determines that the scroll detected on the screen 500 immediately after the state illustrated in FIG. 5B satisfies the predetermined condition, the product description of the items 410_k + 5 to 410_N that should appear on the screen 500 thereafter. From 412_k + 5 to 412_N, delete the words “[Free Shipping]”, “Beer”, “350ml”, “500ml” as common parts, omit the predetermined number of characters from the beginning, and set the character size from the initial value Is also increased, the display mode of the product description 412_k + 5-412_N is changed. Then, when the presentation unit 114 scrolls up from the state shown in FIG. 5B and the item 410_k comes out of the screen 500, as shown in FIG. 5C, 410_k + 1 to 410k + 4 are displayed in the initial state. The item 410_k + 5 is displayed on the screen 500 in the changed display mode. Further, when the items 410_k + 1 to 410_k + 4 come out of the screen 500 by scrolling up from the state shown in FIG. 5C, the items 410_k + 5 to the items 410_k + 5 to 5 in the changed display mode as shown in FIG. 410_k + 9 is displayed on the screen 500.

  If it is determined that the scroll is not detected after the state shown in FIG. 5D or the detected scroll does not satisfy the predetermined condition, the changing unit 113 changes the display form shown in FIG. The display mode is changed to the initial display mode shown in (a). Then, the presenting unit 114 displays the items 410_1 to 410_N on the screen 500 in the initial display mode.

  In the present embodiment, the control unit 101 and the display unit 104 cooperate to function as the presentation unit 114.

  Next, the operation of the display device 100 according to Embodiment 1 of the present invention will be described. The processing described below is started by executing a program on the hardware of the display device 100, and the display device 100 is realized by this processing. FIG. 6 is a flowchart showing the flow of display processing executed by the display device 100. For example, this process starts when the touch panel unit 106 receives a touch operation instructing to load a product list page from the content providing apparatus 200.

  When this process is started, the accepting unit 111 accepts a product list page from the content providing apparatus 200 via the communication unit 105 (step S101).

  The presentation unit 114 displays the product list page received in step S101 on the display unit 104 in the display mode in the initial state (step S102).

  The detection unit 112 determines whether scrolling on the screen of the display unit 104 has been detected (step S103). When it is determined that the scroll is not detected (step S103; No), the detection unit 112 waits until it is determined that the scroll is detected.

  When it is determined that the detection unit 112 has detected scrolling (step S103; Yes), the changing unit 113 determines whether the scroll detected in step S103 satisfies a predetermined condition (step S104). When it is determined that the scroll does not satisfy the predetermined condition (step S104; No), the process returns to step S102.

  When it is determined that the scroll satisfies the predetermined condition (step S104; Yes), the changing unit 113 deletes a common part from the product description included in the product list page and omits a predetermined number of characters from the top. At the same time, the display mode is changed from the initial state by increasing the character size from the initial value (step S105).

  Then, the presentation unit 114 displays the product list page on the screen of the display unit 104 in the display mode changed in step S105 (step S106). Then, the process returns to step S103 and the above-described processing is repeatedly executed.

  As described above, the display device 100 according to the first embodiment of the present invention deletes a part of the product description included in the item when scrolling on the screen satisfies a predetermined condition, and sets the remaining character size. increase. Generally, when the scrolling speed on the screen increases, the amount of information displayed on the screen increases due to the increase in the number of items displayed per unit time. In addition, when the scrolling speed is increased, it is difficult to read a long and small sentence due to an afterimage phenomenon. However, when the scrolling speed on the screen increases, the display device 100 deletes the common part of the product description included in the item and leaves the other part, that is, the important part, thereby removing the item. The item is displayed in a legible state by reducing the amount of information per hit and enlarging the remaining characters of the product description. Therefore, even if scrolling is performed at a high speed, it is possible to prevent a decrease in the value of information provided while suppressing unnecessary display. Also, the user can easily grasp the outline of the item being scrolled and move to the desired item position. In addition, since an afterimage phenomenon is less likely to occur on the screen, the screen is easy to see. In addition, since the character size of the remaining part of the product description is increased, the outline of the product description can be read even when scrolling at a very high speed.

(Embodiment 2)
When the display device 100 according to the first embodiment detects scrolling on the screen, the display device 100 can easily grasp the item by deleting a part of the product description and increasing the character size of the remaining part. However, the method for easily grasping the item is not limited to this. In the second embodiment, when scrolling is detected, an example will be described in which part of the product description is deleted to increase the remaining character size and the product images of the items are further arranged in a direction orthogonal to the scroll direction. In the following description, detailed description of the same configuration as that of the first embodiment will be omitted.

  FIG. 7 is a schematic block diagram illustrating a functional configuration of the display device 100a according to the second embodiment. As illustrated in FIG. 7, the display device 100a functions as a changing unit 113a instead of the changing unit 113 of the display device 100 according to the first embodiment.

  When the scroll detected by the detection unit 112 satisfies a predetermined condition, the changing unit 113a deletes a part of the product description from the item, and changes the product image of the item in the scroll direction and the direction orthogonal to the scroll direction. Line up. Here, the same conditions as in the first embodiment can be applied as the predetermined conditions. Further, the changing unit 113a deletes a part of the product description by the same method as in the first embodiment. Then, the changing unit 113a arranges the items including the remaining part of the product description and the product image in the scroll direction and the direction orthogonal to the scroll direction.

  8A and 8B are display examples of the product list page according to the second embodiment when the scroll detected on the screen 500 after the state shown in FIG. 5B satisfies a predetermined condition. Show. When the changing unit 113a determines that the detected scroll does not satisfy the predetermined condition, the presenting unit 114 starts from the kth item 410_k in the display state in the initial state as illustrated in FIG. It is assumed that the item 410_k + 4 is displayed on the screen 500. In the display state in the initial state, the items 410_k to 410_k + 4 are arranged side by side in the scroll direction, that is, the vertical direction in FIG. Then, when the changing unit 113a determines that the scroll detected on the screen 500 immediately after the state illustrated in FIG. 5B satisfies the predetermined condition, the items 410_k + 5 to 410_N that should appear on the screen 500 thereafter. Delete the words “[free shipping]”, “beer”, “350ml”, “500ml” as common parts from the description 412_k + 5-412_N, omit the predetermined number of characters from the beginning, and initialize the character size Make it larger than the value. Then, the changing unit 113a further arranges the items 410_k + 5 to 410_N in the direction orthogonal to the scroll direction, that is, the left and right direction, and changes the display mode so that the items 410_k + 5 to 410_N are arranged vertically and horizontally. Then, when the presentation unit 114 scrolls up from the state shown in FIG. 5B and the item 410_k comes out of the screen 500, as shown in FIG. 8A, 410_k + 1 to 410k + 4 are displayed in the initial state. The items 410_k + 5 to 410_k + 6 are displayed on the screen 500 in the changed display mode. Further, when the item 410_k + 1 to 410_k + 4 comes out of the screen 500 by scrolling up from the state shown in FIG. 8A, the item 410_k + 5 is changed to the item 410_k + 5 in the changed display mode as shown in FIG. 8B. 410_k + 14 is displayed on the screen 500. 8A and 8B, two items 410_1 to 410_N are arranged in the left-right direction, but the number of items 410_1-410_N arranged in the left-right direction is not limited to this, and an arbitrary number of items 410_1-410_N are arranged. Items 410_1 to 410_N may be arranged in the left-right direction.

  Next, the operation of the display device 100a according to the second embodiment of the present invention will be described. The processing described below is started by executing a program on the hardware of the display device 100a, and the display device 100a is realized by this processing. FIG. 9 is a flowchart showing the flow of display processing executed by the display device 100a. For example, this process starts when the touch panel unit 106 receives a touch operation instructing to load a product list page from the content providing apparatus 200.

  When this process is started, the display device 100a executes steps S101 to S104 of the display process shown in FIG. 6 in steps S201 to S204 as in the first embodiment.

  When it is determined that the scroll satisfies the predetermined condition (step S204; Yes), the changing unit 113a deletes the common part from the product description included in the product list page from the initial display mode, and starts from the top. After the predetermined number of characters is omitted, the character size is increased from the initial value, and the display mode is changed so that items are arranged vertically and horizontally (step S205).

  Then, the presentation unit 114 displays the product list page on the screen of the display unit 104 in the display mode changed in step S205 (step S206). Then, returning to step S203, the above-described processing is repeatedly executed.

  As described above, the display device 100a according to the second embodiment of the present invention deletes a part of the product description included in the item when the scrolling on the screen satisfies the predetermined condition, and sets the remaining character size. While increasing, the product image of an item is further arranged in the direction orthogonal to a scroll direction. Therefore, as in the first embodiment, the user can easily grasp the outline of the item being scrolled and move to the position of the desired item. In addition, since an afterimage phenomenon is less likely to occur on the screen, the screen is easy to see. In addition, since the character size of the remaining part of the product description is increased, the outline of the product description can be read even when scrolling at a very high speed.

(Embodiment 3)
The display device 100 according to the first embodiment includes a product list page 400 including items 410_1 to 410_N having both product images 411_1 to 411_N and product descriptions 412_1 to 412_N as shown in FIG. 4 from the content providing device 200. When the detected scroll satisfies the predetermined condition, the display mode of the product list page 400 acquired in advance is changed and displayed. However, the timing for acquiring information such as product images and product descriptions included in the items is not limited to this. In the third embodiment, when the detected scroll satisfies a predetermined condition, the product description of the item is acquired and displayed, and when the predetermined condition is not satisfied, both the product image and the product description are acquired, or An example in which a product image is acquired and displayed when a product description has already been acquired will be described. In the following description, detailed description of the same configuration as that of the first embodiment will be omitted.

  FIG. 10 is a schematic block diagram illustrating a functional configuration of the display device 100b according to the third embodiment. As illustrated in FIG. 10, the display device 100b functions as a reception unit 111b and a change unit 113b instead of the reception unit 111 and the change unit 113 of the display device 100 according to the first embodiment.

  The accepting unit 111b accepts either the product image and the product description included in the item to be displayed on the screen or the product image and the product description from the content providing apparatus 200 according to the instruction from the changing unit 113b. Then, the reception unit 111b records both the received product image and product description, or the product image and product description in the RAM 103.

  The changing unit 113b acquires a product description to be displayed from the content providing apparatus 200 when the detected scroll satisfies a predetermined condition. Moreover, the change part 113b acquires the goods image and goods description which should be displayed from the content provision apparatus 200, when the detected scroll does not satisfy | fill predetermined conditions. Furthermore, when the detected scroll does not satisfy the predetermined condition, and the product description to be displayed has already been acquired and the product image to be displayed has not been acquired, the change unit 113b receives the product from the content providing apparatus 200. Get an image.

  Hereinafter, the display mode changing method by the changing unit 113b will be specifically described with reference to FIGS. 5A and 5B and FIGS. 11A to 11D. For example, immediately after the product list page 400 is received by the receiving unit 111b and no scroll on the screen 500 is detected, the changing unit 113b displays the product images 411_1 to 411 included in the items 410_1 to 410_5 in the display area. 411_5 and product description 412_1 to 412_5 are acquired via the reception unit 111b and recorded in the RAM 103. And the presentation part 114 displays the item 410_1-410_5 by the display mode of an initial state, as shown to Fig.5 (a).

  Then, after FIG. 5A is displayed, in order to view the sixth and subsequent items 410_6-410_N that are not displayed on the screen 500, for example, the user moves the screen 500 upward with respect to the touch panel unit 106. When the flick is performed, the detection unit 112 detects an upward scroll on the screen 500. If the changing unit 113b determines that the detected scroll does not satisfy the predetermined condition, the product image 411_k to 411_k + 4 and the product description 412_k to 412_k + 4 included in the items 410_k to 410_k + 4 in the display area are received. Obtained via 111 b and recorded in the RAM 103. And the presentation part 114 displays the item 410_k + 4 from the kth item 410_k on the screen 500 by the display mode of an initial state, as shown in FIG.5 (b).

  The changing unit 113b determines that the scroll detected on the screen 500 immediately after the state illustrated in FIG. 5B satisfies a predetermined condition, and scrolls upward from the state illustrated in FIG. Comes out of the screen 500, the product description 412_k + 5 of the item 410_k + 5 newly included in the display area is acquired from the content providing apparatus 200 via the accepting unit 111b and recorded in the RAM 103. Then, the change unit 113b changes the display mode of the item 410_k + 5 by deleting a part of the product description 412_k + 5 to increase the character size and deleting the product image 411_k + 5 as in the first embodiment. Then, as illustrated in FIG. 11A, the presentation unit 114 displays 410_k + 1 to 410k + 4 on the screen 500 in the initial display mode, and displays the item 410_k + 5 on the screen 500 in the changed display mode.

  From the state shown in FIG. 11A, when the detected scroll satisfies a predetermined condition and scrolls upward and items 410_k + 6 to 410_k + 9 are newly included in the display area, the changing unit 113b receives the receiving unit. The product description 412_k + 6 to 412_k + 9 of the items 410_k + 6 to 410_k + 9 is acquired from the content providing apparatus 200 via the 111b and recorded in the RAM 103. And the change part 113b changes the display mode of items 410_k + 6-410_k + 9 similarly to item 410_k + 5. And the presentation part 114 displays the item 410_k + 5-410_k + 9 on the screen 500 with the changed display mode, as shown in FIG.11 (b).

  After that, the detected scroll is scrolled up from the state shown in FIG. 11B while satisfying the predetermined condition, and when the items 410_m to 410_m + 4 are in the display area as shown in FIG. 11C, If the changing unit 113b determines that the scroll is not detected or the detected scroll does not satisfy the predetermined condition, the item descriptions 412_m to 412_m + 4 of the items 410_m to 410_m + 4 are recorded in the RAM 103, but the product image 411_m to It is determined that 411_m + 4 is not recorded, and product images 411_m to 411_m + 4 of items 410_m to 410_m + 4 are acquired from the content providing apparatus 200 via the reception unit 111b and recorded in the RAM 103. And the change part 113b changes from the display mode shown in FIG.11 (c) to the display mode of the initial state shown in FIG.11 (d). Then, the presentation unit 114 displays the items 410_m to 410_m + 4 on the screen 500 in the display state in the initial state.

  When the scroll detected thereafter scrolls down from the state shown in FIG. 11D without satisfying the predetermined condition, and the item displayed in the past satisfying the predetermined condition is displayed again, the change unit 113b determines that the product description of the item in the display area is recorded in the RAM 103 but no product image is recorded, and acquires the product image of the item from the content providing apparatus 200 via the receiving unit 111b. And recorded in the RAM 103. Then, the presentation unit 114 displays the items in the display area on the screen 500 in the display state in the initial state.

  Next, the operation of the display device 100b according to Embodiment 3 of the present invention will be described. The processing described below is started by executing a program on the hardware of the display device 100b, and the display device 100b is realized by this processing. FIG. 12 is a flowchart showing the flow of display processing executed by the display device 100b. For example, this process starts when the touch panel unit 106 receives a touch operation instructing to load a product list page from the content providing apparatus 200.

  When this process is started, the accepting unit 111b accepts a product list page that includes items included in the display area first from the content providing apparatus 200 via the communication unit 105 (step S301). Then, the reception unit 111b records the product image and the product description included in the received item on the product list page in the RAM 103.

  The presentation unit 114 displays the product list page received in step S301 on the display unit 104 in the display mode in the initial state (step S302).

  The detection unit 112 determines whether scrolling on the screen of the display unit 104 has been detected (step S303). When it is determined that the scroll is not detected (step S303; No), the display device 100b executes a second display process described later (step S306).

  When it is determined that the detection unit 112 has detected scrolling (step S303; Yes), the changing unit 113b determines whether the scroll detected in step S303 satisfies a predetermined condition (step S304). When it is determined that the scroll satisfies the predetermined condition (step S304; Yes), the display device 100b executes the first display process shown in FIG. 13 (step S305).

  FIG. 13 is a flowchart showing the flow of the first display process executed by the display device 100b. When this process is started, the changing unit 113b determines whether or not a product description included in an item to be displayed in the current display area is recorded in the RAM 103 (step S401).

  When the changing unit 113b determines that the item description included in the item to be displayed in the current display area is not recorded in the RAM 103 (step S401; No), the changing unit 113b receives the content from the content providing apparatus 200 via the receiving unit 111b. The product description is acquired and recorded in the RAM 103 (step S402).

  The changing unit 113b determines that the item description included in the item to be displayed in the current display area is recorded in the RAM 103 (step S401; Yes), or after the step S402, the current display area The display mode of the item description included in the item to be displayed is changed in the same manner as in step S105 of FIG. 6, and the display mode of the item to be displayed in the current display area is deleted from the initial state by deleting the product image. Change (step S403).

  Then, the presentation unit 114 displays the product list page including the items to be displayed in the current display area on the screen of the display unit 104 in the display mode changed in step S403 (step S404). Then, the display device 100b returns to step S303 in FIG. 12 and repeatedly executes the above-described processing.

  Returning to FIG. 12, when the detection unit 112 determines that the scroll is not detected (step S303; No), or when it is determined that the scroll does not satisfy the predetermined condition (step S304; No), the display device 100b executes a second display process (step S306).

  FIG. 14 is a flowchart showing the flow of the second display process executed by the display device 100b. When this process is started, the changing unit 113b determines whether or not a product description included in an item to be displayed in the current display area is recorded in the RAM 103 (step S501).

  When the changing unit 113b determines that the item description included in the item to be displayed in the current display area is not recorded in the RAM 103 (step S501; No), the changing unit 113b receives the information from the content providing apparatus 200 via the receiving unit 111b. The product description and product image are acquired and recorded in the RAM 103 (step S502).

  When it is determined that the item description included in the item to be displayed in the current display area is recorded in the RAM 103 (step S501; Yes), the changing unit 113b sets the item to be displayed in the current display area. It is determined whether or not the included product image is recorded in the RAM 103 (step S503).

  If the changing unit 113b determines that the product image included in the item to be displayed in the current display area is not recorded in the RAM 103 (step S503; No), the changing unit 113b from the content providing apparatus 200 via the receiving unit 111b The product image is acquired and recorded in the RAM 103 (step S504).

  When the changing unit 113b determines that the product image included in the item to be displayed in the current display area is recorded in the RAM 103 (step S503; Yes), the current value is displayed after step S502 or after step S504. The display mode of the items to be displayed in the display area is returned to the initial state (step S505).

  Then, the presentation unit 114 displays a product list page including items to be displayed in the current display area on the screen of the display unit 104 in the initial display mode (step S506). Then, the display device 100b returns to step S303 in FIG. 12 and repeatedly executes the above-described processing.

  As described above, the display device 100b according to the third embodiment of the present invention acquires a product description from the content providing device 200 when scrolling on the screen satisfies a predetermined condition, and displays the display mode of the product description. Change the display mode of the item by changing and deleting the product image. Further, the display device 100b acquires both the product description and the product image from the content providing device 200 when scrolling on the screen does not satisfy the predetermined condition, or the product when the product description has already been acquired. By acquiring the image, the item is displayed in the initial display mode. In this way, the display device 100b acquires only the information to be displayed included in the item in response to the scrolling, and if some of the information to be displayed has already been acquired, the information to be displayed and the acquisition Since the difference from the completed information is acquired, the communication amount between the display device 100b and the content providing device 200 can be reduced.

  Although the embodiment of the present invention has been described above, the above embodiment is an example, and the scope of application of the present invention is not limited to this. That is, the embodiments of the present invention can be applied in various ways, and all the embodiments are included in the scope of the present invention.

  For example, in the above first to third embodiments, the changing units 113, 113 a, and 113 b include words whose appearance frequency is higher than a predetermined threshold in the item descriptions 412 </ b> _ <b> 1 to 412 </ b> _N of the items 410 </ b> _ <b> 1 to 410_N included in the item list page 400. Is deleted from the product description 412_1 to 412_N as a common part. However, the common part specifying method by the changing units 113, 113a, and 113b is not limited to this. For example, the changing units 113, 113a, and 113b leave portions where the appearance frequency is lower than a predetermined threshold in the product description sentences 412_1 to 412_N, and the search frequency is lower than the predetermined threshold even in a search engine or the like. Other parts may be deleted as common parts.

  In the first to third embodiments, the changing units 113, 113a, and 113b do not change the width in the scroll direction of the items 410_1 to 410_N, that is, the width in the vertical direction. Good.

  In the second embodiment, the changing unit 113a deletes part of the product description sentences 412_1 to 412_N as in the first embodiment, but deletes all of the product description sentences 412_1 to 412_N, and only the product images 411_1 to 411_N. May be displayed.

  FIGS. 15A and 15B show display examples of a product list page on which only product images are displayed. When the changing unit 113a determines that the detected scroll does not satisfy the predetermined condition, the presenting unit 114 starts from the kth item 410_k in the display state in the initial state as illustrated in FIG. It is assumed that the item 410_k + 4 is displayed on the screen 500. Then, when the change unit 113a determines that the scroll detected on the screen 500 after the state illustrated in FIG. 5B satisfies the predetermined condition, the item 410_k + 5 to 410_N and the item that should appear on the screen 500 thereafter The item description 412_k + 5 to 412_N of 410_k + 5 to 410_N is deleted. Then, the changing unit 113a further arranges four items 410_k + 5 to 410_N in the direction orthogonal to the scroll direction, that is, the left and right direction, and changes the display mode so that the items 410_k + 5 to 410_N are arranged vertically and horizontally. Then, when the presentation unit 114 scrolls upward from the state shown in FIG. 5B and the item 410_k comes out of the screen 500, as shown in FIG. 15A, 410_k + 1 to 410k + 4 are displayed in the display state in the initial state. Items 410_k + 5 to 410_k + 8, which are displayed on the screen 500 and include only product images in the changed display mode, are displayed on the screen 500. Further, when the item 410_k + 1 to 410_k + 4 comes out of the screen 500 by scrolling up from the state shown in FIG. 15A, the item 410_k + 5 is changed to the item 410_k + 5 in the changed display mode as shown in FIG. 410_k + 24 is displayed on the screen 500. In FIGS. 15A and 15B, four items 410_1 to 410_N are arranged in the left-right direction, but the number of items 410_1-410_N arranged in the left-right direction is not limited to this, and an arbitrary number of items 410_1-410_N are arranged. Items 410_1 to 410_N may be arranged in the left-right direction. In this way, by arranging only the product images, it is possible to easily grasp the item even when the characters are scrolled at such a high speed that it is difficult to read the characters.

  In the second embodiment and the above-described modification, the changing unit 113a does not change the size of the product images 411_1 to 411_N included in the items 410_1 to 410_N, but the size of the product image may be reduced. .

  Moreover, in said Embodiment 1-3, the change parts 113, 113a, 113b will return to the display state of an initial state, if a scroll is no longer detected. However, the conditions for the changing units 113, 113a, 113b to return to the initial display mode are not limited to this. For example, the change units 113, 113 a, and 113 b may return to the display state in the initial state when the touch panel unit 106 receives an operation to stop scrolling in an instant. Specifically, for example, when the touch panel unit 106 accepts a touch operation for tapping the screen when scrolling is continued by inertial scrolling after flicking, the presentation unit 114 stops scrolling instantaneously. Then, the changing units 113, 113a, 113b have received an operation in which the touch panel unit 106 stops the scroll instantaneously when the scrolling speed detected by the detecting unit 112 reaches zero from the predetermined speed during the predetermined period. It is possible to determine and return to the initial display mode.

  In the first to third embodiments, the changing units 113, 113 a, and 113 b change the items 410 </ b> _ <b> 1 to 410 </ b> _N to be displayed on the screen 500 thereafter when the scrolling speed detected by the detecting unit 112 is lower than the threshold. The display mode may be returned to the display mode before the change, and the display mode of the items 410_1 to 410_N currently displayed on the screen 500 may be maintained until the screen 500 is exited.

  FIG. 16 shows a display example of the product list page when the scrolling speed detected by the detecting unit 112 becomes smaller than the threshold value. When the changing unit 113 determines that the detected scroll satisfies a predetermined condition, the presenting unit 114 displays items from the k + 5th item 410_k + 5 in the changed display mode as illustrated in FIG. Assume that 410_k + 9 is displayed on the screen 500. When the scroll speed detected immediately after the state shown in FIG. 5D is smaller than the threshold, the changing unit 113 performs the items 410_k + 5 to 410_k + 9 displayed in the state shown in FIG. Maintains the display mode after the change until it leaves the screen 500, and returns the display mode of the items 410_k + 10 to 410_N to be displayed to the initial display mode. Then, as shown in FIG. 16, when the item 410_k + 5 comes out of the screen 500 by scrolling up from the state shown in FIG. 5D, the presentation unit 114 displays the items 410_k + 6 to 410_k + 9 in the changed display mode. The newly displayed item 410_k + 10 is displayed in the display state in the initial state.

  Moreover, in said Embodiment 1-3, the change part 113,113a, 113b determines that the detected scroll satisfy | fills predetermined conditions, among items, item 410_k + 5 which should be displayed on the screen 500 after that The display mode of 410_N is changed, and the display mode of the items 410_k to 410_k + 4 currently displayed on the screen 500 is maintained until the display mode 500 comes out. However, when it is determined that the detected scroll satisfies the predetermined condition, the changing units 113 and 113a not only display items 410_k + 5 to 410_N to be displayed on the screen 500 but also items 410_k to be displayed on the screen 500. The display mode of 410_k + 4 may also be changed.

  FIGS. 17A and 17B show display examples of the product list page when the display mode of the items 410_k + 5 to 410_N currently displayed on the screen 500 changes. When the changing units 113 and 113a determine that the detected scroll does not satisfy the predetermined condition, the presenting unit 114 displays the k-th item in the display state in the initial state, as shown in FIG. Assume that items 410_k to 410_k + 4 are displayed on the screen 500. When the change units 113 and 113a determine that the scroll detected on the screen 500 after the state illustrated in FIG. 5B satisfies the predetermined condition, the currently displayed items 410_k to 410_k + 4 and the subsequent screen The display mode of the items 410_k + 5 to 410_N to be displayed on 500 is changed in the same manner as in the first or second embodiment. And when the change part 113 changes the display mode of the items 410_k-410_N similarly to Embodiment 1, as shown to Fig.17 (a), the presentation part 114 changes the item 410_k-410_k + 4 by the changed display mode. It is displayed on the screen 500. Further, when the changing unit 113a changes the display mode of the items 410_k to 410_N as in the second embodiment, the presentation unit 114 displays the items 410_k to 410_k + 9 in the changed display mode as illustrated in FIG. It is displayed on the screen 500.

  Moreover, in said Embodiment 1-3, the change part 113,113a, 113b deletes a part or all of goods description, when it determines with the detected scroll satisfy | filling predetermined conditions, and makes it an item. The display mode of the item may be changed by adding an image.

  FIGS. 18A and 18B show a display example of a product list page when the display mode of an item is changed by deleting a part of the product description and adding an image to the item. When the changing unit 113 determines that the detected scroll does not satisfy the predetermined condition, the presentation unit 114 starts from the kth item 410_k in the display state in the initial state as shown in FIG. It is assumed that the item 410_k + 4 is displayed on the screen 500. Then, when the changing unit 113 determines that the scroll detected on the screen 500 after the state illustrated in FIG. 5B satisfies the predetermined condition, the item description of the items 410_k + 5 to 410_N that should appear on the screen 500 thereafter. From the sentences 412_k + 5 to 412_N, the words “[free shipping]”, “beer”, “350 ml”, “500 ml” are deleted as common parts, the predetermined number of characters from the beginning are omitted, and the character size is set to the initial value. The display mode of the product description 412_k + 5-412_N is changed by making it larger. Furthermore, the changing unit 113 acquires product images 414_k + 5 to 414_N that are different from the product images 411_k + 5 to 411_N of the items 410_k + 5 to 410_N that should appear on the screen 500 thereafter, for example, from the content providing apparatus 200 and adds them to the items 410_k + 5 to 410_N. , The display mode of the items 410_k + 5 to 410_N is changed. Then, when the presentation unit 114 scrolls upward from the state shown in FIG. 5B and the item 410_k comes out of the screen 500, as shown in FIG. 18A, 410_k + 1 to 410k + 4 are displayed in the display state in the initial state. The item 410_k + 5 is displayed on the screen 500 in the changed display mode. Further, when the items 410_k + 1 to 410_k + 4 come out of the screen 500 by scrolling up from the state shown in FIG. 18A, as shown in FIG. 18B, the presenting unit 114 changes the items 410_k + 5 to 5 in the changed display mode. 410_k + 9 is displayed on the screen 500.

  In the example shown in FIGS. 18A and 18B above, the changing unit 113 has changed the display mode of the item by deleting a part of the product description and adding an image to the item. You may change the display mode of an item by deleting the whole explanatory note and adding a product image. Further, the number of product images added to an item is not limited to one, and an arbitrary number of product images can be added. In addition, the changing unit 113a according to the second embodiment deletes part or all of the product description, and arranges the items after adding an image to the items in a scroll direction and a direction orthogonal to the scroll direction. The display mode of the item may be changed. In this way, by deleting a part or all of the product description and adding a product image, the amount of information reduced by the deleted part of the product description can be compensated by the product image.

  In the first to third embodiments, the example in which the touch panel unit 106 is used as an operation unit that receives an operation for instructing scrolling from the user has been described. However, the operation unit is not limited thereto, and an input device such as a button or a keyboard is used. May be configured.

  In the first to third embodiments, an example in which the detection unit 112 detects scrolling of content on the screen when the display unit of the content displayed on the screen of the display unit 104 is moved by the presentation unit 114 will be described. However, the method of detecting scrolling on the screen is not limited to this. For example, the detection unit 112 may detect scrolling based on a touch operation received by the touch panel unit 106. Specifically, when it is determined that the touch panel unit 106 has received a flick or slide in a scrollable direction on the screen as the touch operation, the detection unit 112 determines that scrolling has been detected. In addition, when the presentation unit 114 can scroll the content by inertial scrolling, the detection unit 112 is based on the flicking speed and the friction coefficient until the touch panel unit 106 accepts a flick and then accepts the next touch operation. Then, the scroll speed may be calculated, and if the calculated scroll speed is not 0, it may be determined that the scroll is detected.

  In the first to third embodiments, the changing units 113, 113a, and 113b detect the amount of change in the coordinate position of the content display area, and calculate the amount of change in the coordinate position per unit time. Although the example which detects a speed was demonstrated, the detection method of the speed of a scroll is not restricted to this. For example, the change units 113, 113 a, and 113 b may detect the scroll speed based on the touch operation accepted by the touch panel unit 106. Specifically, the changing units 113, 113 a, and 113 b can calculate the scrolling speed based on the flicking speed and distance received by the touch panel unit 106. In addition, when the presentation unit 114 can scroll the content by inertial scrolling, the detection unit 112 is based on the flicking speed and the friction coefficient until the touch panel unit 106 accepts a flick and then accepts the next touch operation. Thus, the scrolling speed may be calculated.

  In the third embodiment, the item description of the item is acquired when the scroll satisfies the predetermined condition, and the product description and the product image are acquired from the content providing apparatus 200 when the scroll does not satisfy the predetermined condition. Alternatively, an example in which a product image is acquired when a product description has already been acquired has been described. However, the item information that the display device 100b acquires in response to scrolling is not limited to this. The display device 100b acquires a part to be displayed among the information included in the item when the scroll satisfies a predetermined condition, and the scroll does not satisfy the predetermined condition and does not acquire a part of the information. When all of the information is acquired, when the scrolling does not satisfy the predetermined condition, and part of the information has already been acquired, and all of the information has not been acquired, the remaining part of the information excluding part of the information is acquired. do it.

  For example, the display device 100b acquires and displays a product image among the information included in the item when the scroll satisfies a predetermined condition, and the scroll does not satisfy the predetermined condition and does not acquire the product image. When the product image and the product description are acquired, and the scroll does not satisfy the predetermined condition, the product image is already acquired, and the product description is not acquired, the product description may be acquired.

  In addition, for example, when the content providing apparatus 200 holds in advance, in addition to the item description of the item, a part of the item description, for example, a simple item description, the display device 100b is scrolled. When a predetermined condition is satisfied, a product image and a simple product description may be acquired from the content providing apparatus 200 and displayed as part of the item information. In addition, when the scroll does not satisfy the predetermined condition and the product image and the simple product description are not acquired, the product image and the product description are acquired, and the scroll does not satisfy the predetermined condition and the product image If a simple product description has been acquired, a product description may be acquired.

  Moreover, in said Embodiment 1-3, although the display apparatus 100,100a, 100b demonstrated the example which receives a content via the internet 300 from the content provision apparatus 200, display apparatus 100,100a, 100b displays. The content to be stored may be stored in a ROM or the like in advance.

  The display devices 100, 100a, and 100b according to the present invention can be provided with a configuration for realizing the above functions in advance, and can be provided with an existing personal computer or information terminal device by applying a program. Can also function as the display devices 100, 100a, and 100b according to the present invention. That is, an existing personal computer so that a CPU for controlling the existing personal computer or the information terminal device can execute a program for realizing each functional configuration by the display devices 100, 100a, and 100b exemplified in the above embodiment. When applied to the information terminal device, the personal computer or the information terminal device can function as the display devices 100, 100a, 100b according to the present invention. The display method according to the present invention can be implemented using the display devices 100, 100a, and 100b.

  Further, such a program is not limited to the above, and can be applied by an arbitrary method.
