Description

  The present invention relates to a content display method.

  In recent years, it has become common for users to select content that they want to view from a large number of content. In other words, for example, there are a wide variety of broadcast program providing methods, and the number of contents that can be viewed is increased accordingly, so the user selects a broadcast program that the user wants to view from a large number of broadcast programs. . In addition, since the performance of storage media has increased, a large number of contents can be stored. Therefore, the user selects a content that the user wants to view from the stored many contents.

  As a method for selecting a content to be viewed from a large number of contents, for example, a method of changing the number of contents to be displayed at a time according to the rotation speed of a jog dial is known (Patent Document 1). That is, in Patent Document 1, when the rotation speed of the jog dial is increased, the scrolling speed is increased and the size of each scrolled content is reduced so that the number of displayed content is increased. Yes.

As another method, for example, a method is known in which still images are classified according to shooting time or the like, and the representative images are displayed as thumbnails in response to a request from the user (Patent Document 2).
Japanese Patent Laid-Open No. 2003-044194 JP 2006-0665368 A

  However, depending on the content, there are cases where the content to be viewed cannot be selected efficiently.

  That is, for example, when a plurality of contents are classified according to a request from the user and the representative images are switched and displayed, the instruction for classifying the contents and the instruction for switching the representative images are different operations. It was necessary to do in.

  In addition, for example, in the method of reducing the size of content displayed scrolling according to the rotation speed of the jog dial and increasing the number of displayed contents, if the rotation speed of the jog dial is increased too much, the small content becomes faster. Because it scrolls, there is a risk of missing the content you want to watch.

  The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to more efficiently select a content to be viewed from a plurality of contents.

In order to solve the above problems, a display control apparatus according to the present invention has, for example, the following configuration. That is, a display control apparatus for scrolling and displaying a plurality of contents, showing a scroll means for scrolling the plurality of contents, and a method for classifying the plurality of contents according to the scrolling speed by the scroll means. Display control means for displaying an image and displaying the classification information of the plurality of contents by the determined classification method.

Moreover, the display control method of this invention is provided with the following structures, for example. That is, a display control method performed by a display control device that scrolls and displays a plurality of contents, wherein the plurality of contents are scrolled according to a scrolling step of scrolling the plurality of contents and the scrolling speed by the scrolling step. A display control step of displaying an image showing the classification method and displaying classification information of the plurality of contents by the determined classification method.

  The display control device of the present invention is a display control device that scrolls and displays a plurality of contents, and uses the scroll means for scrolling the plurality of contents and the plurality of content classification information. Classification means for classifying content, and display control means for displaying the result of classification by the classification means in accordance with the speed of scrolling by the scroll means.

  The display control method of the present invention is a display control method performed by a display control device that scrolls and displays a plurality of contents, and includes a scrolling process for scrolling the plurality of contents, and a speed of the scrolling by the scrolling process. A switching step of switching whether to display the classification information so that the classification information of the plurality of contents is displayed accordingly.

  According to the present invention, it is possible to more efficiently select a content to be viewed from a plurality of contents.

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

<Embodiment 1>
FIG. 1 is a block diagram illustrating a functional configuration example of the display control apparatus 100 according to the present embodiment. Note that the display control apparatus 100 of this embodiment is a display control apparatus that scrolls and displays a plurality of contents. Further, the display control apparatus 100 according to the present embodiment may be an apparatus incorporated in the display apparatus or a single apparatus connected to the display apparatus. That is, the display control apparatus 100 of this embodiment may be incorporated in devices such as personal computers, workstations, notebook PCs, various home appliances with built-in computers, game machines, mobile phones, digital video cameras, and digital cameras. good.

  In this embodiment, an example in which a moving image content to be viewed is selected from a plurality of moving image contents will be described. However, it is not limited to moving image content, and may be, for example, still images, audio data, other stream data, or a combination thereof.

  As shown in FIG. 1, the display control apparatus 100 of this embodiment includes an attribute acquisition unit 101, a scroll information acquisition unit 102, an image generation unit 103, a boundary determination unit 104, and a display control unit 105. In addition, the display control apparatus 100 of this embodiment is connected to the operation unit 120, the content storage unit 121, and the display unit 122 by wire or wirelessly.

  The operation unit 120 is, for example, a remote controller for the user to specify a scroll operation or content that the user wants to view. The scroll information by the scroll operation input from the operation unit 120 is output to the scroll information acquisition unit 102 and the display control unit 105. Further, the designation information of the content to be viewed input from the operation unit 120 is output to the display control unit 105.

  The content storage unit 121 stores moving image content and attribute information of each moving image content. Then, the content storage unit 121 notifies the attribute acquisition unit 101 of attribute information of each video content in response to a request from the attribute acquisition unit 101. In addition, the content storage unit 121 outputs thumbnail images (content images) of a plurality of moving image contents to the display control unit 105. In addition, the content storage unit 121 outputs the data of the specified moving image content to the display control unit 105.

  The display unit 122 displays a still image, a moving image, or the like according to the output from the display control unit 105. That is, the display unit 122 displays, for example, a thumbnail image (content image) for specifying the moving image content in accordance with the output from the display control unit 105. In addition, the display unit 122 displays the specified moving image content according to the output from the display control unit 105.

  The attribute acquisition unit 101 acquires attribute information of moving image content. That is, the attribute acquisition unit 101 acquires attribute information corresponding to a plurality of contents stored in the content storage unit 121. Details of the attribute information will be described later.

  The scroll information acquisition unit 102 acquires scroll information corresponding to the scroll operation from the operation unit 120. That is, when a scroll operation is performed from the operation unit 120, the scroll information acquisition unit 102 acquires, for example, information indicating the scroll speed as scroll information. Then, the scroll information acquisition unit 102 notifies the boundary determination unit 104 of the acquired scrolling speed.

  The boundary determination unit 104 compares the scroll information notified from the scroll information acquisition unit 102 with a boundary condition. That is, the boundary determination unit 104 compares the scrolling speed notified from the scroll information acquisition unit 102 with a preset speed. Then, the boundary determination unit 104 determines whether to switch the classification level according to the comparison result. Here, the classification level indicates the breadth of the range corresponding to each classification when content is classified. That is, when classified at a low classification level, each moving image content belonging to a plurality of classifications belongs to a certain classification when classified at a higher classification level. Here, when the classification level increases, the plurality of contents are roughly classified according to the attributes.

  As an example for explaining the classification level, for example, a case where a plurality of contents are classified according to program categories will be specifically described. Here, the lowest classification level is a state in which a content image is displayed. Here, the content image is, for example, a thumbnail image corresponding to each moving image content stored in the content storage unit 121. That is, the state in which each content image currently scroll-displayed has a one-to-one correspondence with the moving image content stored in the content storage unit 121 is the state of the lowest classification level. When the one-step classification level is raised above the lowest classification level, for example, the following classification information is used as classification information for classifying moving image content. That is, “domestic news program”, “overseas news program”, “weather forecast”, “baseball”, “soccer”, “tennis”, “sumo”, “quiz program”, “health program”, and the like. That is, for example, content having the attribute information “domestic news program” belongs to the same category. Then, when the one-step classification level is further increased from that state, for example, “news”, “sports”, and “variety” are used as classification information for classifying a plurality of moving image contents. In this example, it is assumed that “news”, “sports”, and “variety” are the classification information of the highest classification level. Thus, each moving image content is classified according to the classification information corresponding to the classification level and the attribute information that the moving image content has.

  In this example, contents classified as “domestic news program”, “overseas news program”, and “weather forecast” at a classification level that is one step higher than the lowest classification level are displayed as “ "News". In addition, content classified as “baseball”, “soccer”, “tennis”, and “sumo” at a classification level one level higher than the lowest classification level is classified as “sports” at a classification level one level higher than that. The Further, content classified as “quiz program” and “health program” at a classification level one level higher than the lowest classification level is classified as “variety” at a classification level one level higher than that.

  As described above, when classified at a lower classification level, each moving image content belonging to a plurality of classifications (for example, “baseball”, “soccer”, “tennis”, “sumo”) is classified at a higher classification level. It belongs to one certain classification (“sports”).

  Further, as another example for explaining the classification level, a case where a plurality of contents are classified according to the broadcast start time will be described. Here, when the one-level classification level is raised from the lowest classification level, for example, the broadcast start time of each moving image content is classified every three hours. That is, an example of classification information used for classifying a plurality of contents when the one-level classification level is raised from the lowest classification level is as follows. That is, “broadcast start time from 0 to 3 o'clock”, “broadcast start time from 3 o'clock to 6 o'clock”,... “Broadcast start time from 18 o'clock to 21 o'clock”, “broadcast start time from 21 o'clock to 24 o'clock” Until. " That is, content having attribute information that the broadcast start time is 16:00 is classified as “broadcast start time 15:00 to 18:00”. Thus, each moving image content is classified according to the classification information corresponding to the classification level and the attribute information that the moving image content has. Then, when the one-step classification level is further increased from this state, for example, the moving image content is classified by dividing the broadcast start time every 6 hours. That is, the classification information for classifying the moving image content at this time is “broadcast start time from 0:00 to 6:00”, “broadcast start time from 6:00 to 12:00”, and “broadcast start time from 12:00 to 18:00”. "Broadcast start time from 18:00 to 24:00". That is, in this example, for example, the classification level that divides the broadcast start time every 3 hours is higher than the classification level that divides the broadcast start time every 6 hours. That is, in this example, a state where the moving image content stored in the content storage unit 121 is not classified is the lowest classification level. Further, when the broadcast start time is divided every three hours, the classification level is one step higher than the lowest classification level, and when the broadcast start time is divided every six hours, the highest classification level. That is, for example, when each moving image content belonging to “broadcast start time from 0:00 to 3 o'clock” and “broadcast start time from 3 o'clock to 6 o'clock” is classified at a higher classification level, for example, “broadcast start time” “Time from 0:00 to 6:00”. As described above, when classified at a low classification level, each moving image content belonging to a plurality of classifications belongs to one classification when classified at a higher classification level.

  As another example for explaining the classification level, a case will be described in which a plurality of contents are classified by broadcast date. In this example, when the one-level classification level is raised from the lowest classification level, for example, the broadcast date of each moving image content is classified by dividing every week. Further, when the one-step classification level is further increased, for example, each moving image content is classified by dividing the broadcast date every month. When the classification level is further increased, for example, the broadcast date of each moving image content is divided and classified every year. The highest classification level is when the broadcast date is divided every year.

  In this embodiment, a plurality of moving image contents are classified according to the above classification level. However, the classification level hierarchy and the classification information used for classification are not limited to the above example. The boundary determination unit 104 of this embodiment has information on the classification level corresponding to each classification information in advance. That is, each content includes “domestic news program”, “overseas news program”, “weather forecast”, “baseball”, “soccer”, “tennis”, “sumo”, as classification information of the first classification level. "Quiz program", "health program", etc. are given. Each content is given “news”, “sports”, “variety”, etc. as the classification information of the second classification level. Depending on which level of classification information is displayed, the level of classification information to be displayed is displayed. For example, when displaying the classification information of the first classification level, the classification information of the first classification level assigned to the selectable content is displayed. Further, when displaying the classification information of the second classification level, the classification information of the second classification level given to the selectable content is displayed. And the boundary determination part 104 of this form switches the classification information (classification level) for classifying content according to the comparison result of the speed of scrolling.

  The image generation unit 103 generates an image (classification information image) indicating the classification information of the moving image content. Note that the image generation unit 103 of the present embodiment generates a still image indicating classification information corresponding to a plurality of contents, but may generate a moving image or the like. Further, the image generation unit 103 may generate a classification information image in advance, or may generate the classification information image in response to the boundary determination unit 104 determining that the classification information image is to be displayed. In this embodiment, when content is classified according to the category of the program, the attribute information (for example, sports, quiz, baseball) possessed by the content and the classification information displayed on the screen are the same. On the other hand, for example, when content is classified according to broadcast start time, the attribute information (for example, 13:15) that the content has differs from the classification information (for example, from 15:00 to 18:00) displayed on the screen. As described above, the attribute information included in the content and the classification information shown in the classification information image may be the same or different. The image generation unit 103 outputs the generated classification information image data to the display control unit 105.

  The display control unit 105 causes the display unit 122 to display, for example, a thumbnail image (content image) for specifying the moving image content stored in the content storage unit 121. The display control unit 105 scrolls and displays a plurality of content images in response to a scroll operation from the operation unit 120. That is, the display control unit 105 scrolls a plurality of contents (content images). Further, the display control unit 105 reads the moving image content from the content storage unit 121 according to the content image designation information received from the operation unit 120 and causes the display unit 122 to display the moving image content. When the display control unit 105 receives the classification information image data from the image generation unit 103, the display control unit 105 causes the display unit 122 to display the classification information image. The classification information image is received according to the scrolling speed. That is, the display control unit 105 switches whether to display the classification information (classification information image) so that the classification information corresponding to a plurality of contents is displayed according to the scrolling speed.

  Next, the flow of processing performed by the display control apparatus 100 according to the present embodiment will be described. FIG. 2 is a flowchart showing the flow of display control processing performed by the display control apparatus 100 of the present embodiment. Note that the display control apparatus 100 according to this embodiment performs processing of each unit illustrated in FIG. 1 using dedicated hardware. However, these processes can also be performed by software. That is, the processing described in the present embodiment may be performed by a CPU that controls each unit of the display control apparatus 100 reading and executing a program stored in a ROM or the like.

  In the present embodiment, the process of FIG. 2 is started together with the scroll operation of the displayed content. In S201 (scroll procedure), the display control unit 105 displays thumbnail images (content images) of a plurality of contents that are candidates for contents to be viewed on the display screen of the display unit 122 while scrolling. In this embodiment, a plurality of content images are displayed in a stopped state until scrolling is started. However, for example, scrolling may be started in conjunction with activation of the display unit 122. The content image has a one-to-one correspondence with the content stored in the content storage unit 121, and the content desired to be viewed can be reproduced by selecting the content image. That is, in S201, the display control unit 105 scrolls and displays a plurality of contents (content images). However, the scrolled content image is not limited to a thumbnail still image, and may be, for example, a moving image or may include sound. Further, the display control unit 105 displays the content image by scrolling at a scrolling speed according to the scroll operation from the operation unit 120. Further, the scroll display of the content image or the classification information image by the display control unit 105 is continuously performed while the processing of FIG. 2 is being executed.

  In S <b> 202, the scroll information acquisition unit 102 acquires scroll speed information from the input information from the operation unit 120. This scroll speed information is, for example, information on the amount of change in scroll speed from the time when the amount of change in scroll speed was acquired last time. In this embodiment, the scrolling speed is changed according to the coordinate position of the mouse pointer 404 operated by the operation unit 120. That is, in the display screen as shown in “1. start” of FIG. 4, by placing the mouse pointer 404 on the display screen 401 to the left of the center line 419 drawn in the vertical direction, the scrolling speed is positively accelerated to the left. Is given. On the other hand, by placing the mouse pointer 404 on the right side of the center line, a positive acceleration is given to the scroll speed in the right direction. That is, for example, when the mouse pointer 404 is placed on the left side of the center line, the scrolling speed is “+1” every second, and when the mouse pointer 404 is placed on the right side of the center line, every second. The scroll speed is set to “−1”. If it is not desired to change the scrolling speed, the mouse pointer 404 is placed outside the display screen 401. If the scroll speed is a positive value, the display control unit 105 scrolls leftward at a speed corresponding to the absolute value of the scroll speed, and the scroll speed value is a negative value. If there is, scroll to the right. Therefore, the scroll information acquisition unit 102 uses the coordinate information of the mouse pointer 404 input from the operation unit 120 to display scroll speed information (the scroll speed from the time when the amount of change in the previous scroll speed is acquired). Change information).

  However, the method of changing the scrolling speed is not limited to the above method, and the magnitude of the acceleration given to the scrolling speed varies depending on the distance from the center of the screen at the position indicated by the mouse pointer 404, for example. You may do it.

  Further, for example, the scrolling in the left direction or the right direction may be accelerated in proportion to the time from when the mouse button is pressed to the release with respect to the left arrow display 402 or the right arrow display 403 in FIG. . In such a case, the scroll information acquisition unit 102 is based on the coordinate information of the mouse pointer input from the operation unit 120, the position information of the left arrow display 402 and the right arrow display 403, and the information related to the action of the mouse button. Get information about scrolling speed.

  The scroll information acquisition unit 102 outputs the scroll speed information acquired in S202 to the boundary determination unit 104, and proceeds to S203.

  In step S203, the boundary determination unit 104 determines whether acceleration or deceleration is instructed for the scroll speed based on the scroll speed information output from the scroll information acquisition unit 102 in step S202.

  If the boundary determination unit 104 determines in S203 that an instruction for acceleration or deceleration has not been issued, the process proceeds to S215. If the boundary determination unit 104 determines that acceleration has been instructed for the scrolling speed, the process proceeds to S204. On the other hand, if the boundary determination unit 104 determines that deceleration is instructed for the scrolling speed, the process proceeds to S210. Note that when the process of S203 is performed for the first time from the start of the scroll display, for example, the process may proceed to S215.

  In S204, the boundary determination unit 104 determines whether or not the current classification level is the highest classification level. That is, the display control apparatus 100 according to the present embodiment determines whether or not the classification level can be further increased.

  In S204, if the boundary determination unit 104 determines that it is the highest classification level, the process proceeds to S215, and if it is determined that it is not the highest classification level, the process proceeds to S205.

  In step S <b> 215, the display control unit 105 determines whether an operation for ending scroll display has been performed from the operation unit 120. If it is determined in S215 that an operation to end scroll display has been performed, for example, due to an instruction to stop scrolling or the display unit 122 is turned off, the process ends. On the other hand, if it is determined not to end the scroll display, the process returns to S201. That is, if it is determined in S204 that the classification level has already been reached, the display control unit 105 determines that the classification level cannot be increased any further, and performs scroll continuation or termination processing.

  In S205, the boundary determination unit 104 determines whether the scroll speed is equal to or higher than the first predetermined value. If it is determined in S205 that the scrolling speed is equal to or higher than the first predetermined value, the process proceeds to S206, and if it is determined that the scrolling speed is slower than the first predetermined value, the process proceeds to S215. The first predetermined value may be a constant value or a different value depending on the current classification level. As an example of setting the first predetermined value to a constant value regardless of the current classification level, for example, there is a case where the scrolling speed is decreased when the classification level is increased. This process will be described later.

  In S <b> 206, the attribute acquisition unit 101 acquires attribute information corresponding to a plurality of contents stored in the content storage unit 121. The attribute information includes, for example, attribute information (for example, sports, baseball, and high school baseball) related to a program category, and attribute information related to a broadcast time (for example, broadcast date, broadcast start time, broadcast time). As described above, attribute information related to a plurality of program categories and attribute information related to a plurality of broadcast times may correspond to one content. In step S206, the attribute acquisition unit 101 acquires attribute information corresponding to the current classification level. For example, when the classification level is low, the attribute information acquired by the attribute acquisition unit 101 in S206 is, for example, high school baseball or professional baseball. In a state where the classification level is higher than that, the attribute information acquired in S206 is For example, baseball. The attribute acquisition unit 101 notifies the image generation unit 103 of the acquired attribute information. In step S <b> 206, the image generation unit 103 generates a plurality of images indicating a plurality of content classification methods according to the attribute information notified from the attribute acquisition unit 101. Then, the image generation unit 103 outputs a plurality of image data indicating the content classification method to the display control unit 105. Further, the display control unit 105 causes the display unit 122 to display an image indicating the input content classification method, and the process proceeds to S207. The image indicating the content classification method is, for example, an image as illustrated in classification method candidates 601, 602, and 603 illustrated in “3. Response” in FIG. As shown in the figure, the classification method candidate 601 has a character string “program category”, the classification method candidate 602 has “past broadcast date”, and the classification method candidate 603 has a character string “past broadcast time”. Is displayed. Note that the image generation unit 103 may create an image indicating a content classification method in advance. Details of the classification method candidate images will be described later.

  In step S207, the image generation unit 103 determines whether a classification method has been determined. That is, the image generation unit 103 selects one of the plurality of images (classification method candidates 601, 602, 603) indicating the content classification method displayed in S 206, and thereby selects a plurality of content items. Determine whether the classification method has been determined. As described above, the content classification method includes, for example, the program category (corresponding to the classification method candidate 601), the broadcast date of the program (corresponding to the classification method 602), and the broadcast start time of the program (classification method candidate). Corresponds to 603). However, the content classification method is not limited to these methods. If it is determined in S207 that the classification method has been determined, the process proceeds to S208. If it is determined that the classification method has not been determined, the process proceeds to S215.

  In step S208, the image generation unit 103 generates a classification information image to be displayed on the display unit 122 according to the content classification method determined in step S207. Then, the image generation unit 103 outputs the generated classification information image to the display control unit 105, and the process proceeds to S209. The classification information image is an image generated so that the above classification information can be understood. When the category of the program is selected, classification information images (character strings) such as “baseball”, “quiz”, “weather forecast”, “domestic news” are generated.

  In step S <b> 209 (switching procedure), the display control unit 105 displays the classification information image received from the image generation unit 103 on the display screen of the display unit 122. In other words, when the content image is displayed, it is determined in S205 that the scrolling speed is equal to or higher than the first predetermined value, and when the classification method is determined in S207, a plurality of contents are supported instead of the content image. An image of classification information to be displayed is displayed. That is, in S209, the display control unit 105 determines whether or not to display the classification information so that the classification information (classification information image) of a plurality of contents is displayed when the scrolling speed reaches a predetermined speed. Switch. Examples of classification information images displayed by the processing of S209 are shown in “5. Response” classification information images 801, 804, and 805 in FIG. In this example, since the classification method candidate 601 is selected at the stage of “4. operation”, it is determined in S207 that the content is classified according to the program category, so that the classification information regarding the program category is displayed. become. In this embodiment, the classification information image is a still image, but may be an image including a moving image or sound. Further, the classification information image of this embodiment is an image in which the classification information is indicated by characters, but the classification information may be expressed by combining it with an illustration or the like.

  In addition, when the classification level is increased in S209, the display control unit 105 according to the present embodiment decreases the scrolling speed. That is, when the first predetermined value is set so fast that the contents of each displayed image cannot be confirmed, and the scrolling speed is maintained even when the classification level is changed, the newly displayed classification is displayed. There is a possibility that the classification information indicated by the information image cannot be confirmed. Therefore, when the classification level is increased, the display control unit 105 of the present embodiment decreases the scrolling speed so that it is easy to confirm the contents of the newly displayed classification information image.

  That is, the display control unit 105 reduces the scrolling speed in response to switching to display the classification information. However, the scrolling speed may not be changed according to the change of the classification level.

  If the classification information image has already been displayed and if it is determined in S205 that the scrolling speed is equal to or higher than the first predetermined value, the classification level higher than the classification information corresponding to the current classification level. The classification information image of the classification information corresponding to is displayed. The first predetermined value may be a different value depending on the classification level at that time. However, for example, when the scrolling speed is decreased by increasing the classification level, the first predetermined value may be a constant value.

  Here, the classification level and the corresponding classification information will be specifically described. For example, the classification information images displayed according to the current classification level are, for example, “domestic news program”, “overseas news program”, “weather forecast”, “baseball”, “soccer”, “tennis”, “sumo” ”,“ Quiz program ”, and“ health program ”. In this case, when the classification level is further increased, the displayed classification information is, for example, “news”, “sports”, and “variety”. Thus, as the classification level increases, the number of displayed classification information decreases.

  That is, when the scroll speed reaches the first speed (first predetermined value), the display control unit 105 displays the first classification information (classification information image) corresponding to a plurality of contents. Further, when the scroll speed reaches a second speed that is faster than the first speed (first predetermined value), the first of the classification levels higher than the first classification information corresponding to the plurality of contents. 2 classification information is displayed.

  As described above, when the classification level is raised in a state where the classification information is already displayed, the processes of S206 and S207 may be omitted.

  When the display control unit 105 displays the classification information image in S209, the process proceeds to S215.

  On the other hand, if the boundary determination unit 104 determines that the scrolling speed is slow in S203, the boundary determination unit 104 proceeds to S210 and determines whether or not it is the lowest classification level. An example of the case where it is determined that the level is the lowest classification level is a case where the image displayed in a scrolling manner and the content stored in the content storage unit 121 have a one-to-one correspondence as described above. . That is, when the content image is displayed instead of the classification information image, it is determined to be the lowest classification level. If it is determined in S210 that the level is the lowest classification level, the process proceeds to S213, and if it is determined that the level is not the lowest classification level, the process proceeds to S211.

  In S211, the boundary determination unit 104 determines whether the scroll speed is equal to or less than a second predetermined value. If it is determined in S211 that the scroll speed is equal to or lower than the second predetermined value, the process proceeds to S212, and if it is determined that the scroll speed is higher than the second predetermined value, the process proceeds to S215. The second predetermined value is a threshold for scrolling speed for lowering the classification level. Further, the second predetermined value may be a different value depending on the current classification level.

  In S212, the display control unit 105 lowers the current classification level. That is, for example, when the classification information image of the highest classification level is displayed, the classification information image corresponding to the classification level one level lower than the highest classification level is displayed by the process of S212. For example, when a classification information image corresponding to a classification level that is one step higher than the lowest classification level is displayed, the display is switched from the classification information image display to the content image display by the process of S212. When the display control unit 105 finishes the process of lowering the classification level, the process proceeds to S215. Note that, when the classification level is lowered in S212, the display control unit 105 sorts the content image or the classification information image displayed in accordance with the classification level according to the classification information that has been used for content classification so far. That is, for example, when the image displayed on the content image changes from the classification information image by the process of S212, the display order of the plurality of content images displayed is such that the content images of the content corresponding to the same classification information are adjacent to each other. Order.

  That is, the display control unit 105 prevents the classification information image from being displayed when the scrolling speed reaches a predetermined speed in a state where the classification information (classification information image) is displayed. The contents (content images) are displayed in order. The predetermined speed here corresponds to the scroll speed equal to or less than the second predetermined value.

  The sorting of the display order when the classification level is lowered will be specifically described. First, it is assumed that the display order of the displayed content images at the start of scrolling is the order stored in the content storage unit 121. That is, at the start of scrolling, the display order of each content image is not sorted according to the program category. On the other hand, it is assumed that, for example, a program category is selected in advance as a content classification method. At this time, on the display screen, for example, “domestic news program”, “overseas news program”, “weather forecast”, “baseball”, “soccer”, “tennis”, “sumo”, “quiz program”, “ Each classification information image of “health program” is displayed. Here, when a content image is displayed by the process of S212, the display order of each content image is sorted so that it may become the order according to the category of said program. “5. Response” in FIG. 5 indicates that as a result of the sorting, contents belonging to the baseball category (channel 12, channel 60) and contents belonging to the quiz category (channel 3, channel 600) are collected. .

  On the other hand, if it is determined in S210 that the level is the lowest classification level, the process proceeds to S213.

  In step S <b> 213, the display control unit 105 determines whether moving image content to be viewed is specified by an operation from the operation unit 120. If it is determined that the moving image content to be viewed has been specified, the process proceeds to S214. If it is determined that the moving image content is not specified, the process proceeds to S215.

  In step S214, the display control unit 105 reads the designated moving image content from the content storage unit 121, causes the display unit 122 to display it, and ends the scrolling process. That is, if it is determined in S210 that the level is already at the lowest classification level, the classification level cannot be lowered any further even if the scrolling speed is slow, and the process proceeds to a process for determining whether or not the content to be viewed has been selected.

  In this embodiment, the content to be viewed can be specified when the content image is displayed (at the lowest classification level). However, for example, a classification information image corresponding to a classification level that is one step lower than the classification information may be displayed by designating the displayed classification information image using the operation unit 120. Further, a configuration may be adopted in which a content image corresponding to the classification information of the classification information image specified by the operation unit 120 is displayed, and the content to be viewed can be specified from the content image.

  Next, an example of an operation from the operation unit 120 and a change in the display screen of the display unit 122 due to the operation will be described in detail using the drawings.

  FIG. 3 is a diagram illustrating an example of an operation performed by the viewer and a change in the display unit 122 caused by the operation.

  In FIG. 3, each state shown within a dotted line 310 corresponds to the display screens of FIGS. That is, the display example of the display screen in the state “1. start” in FIG. 3 corresponds to “1. start” in FIG. 4, and the display example of the display screen in the state “2. Operation” in FIG. 2. Corresponding to “8.end”, such as “operation”. The display unit 400 in FIGS. 4 to 6 corresponds to the display unit 122 in FIG.

  In this embodiment, the process of FIG. 3 is started together with the scroll operation of the displayed content.

  In the state “1. start”, the display control unit 105 displays a content image (301). That is, the display control unit 105 scrolls and displays the content image at the start of processing. The display screen 401 at this time is as shown in “1. start” in FIG.

  In FIG. 4, content images 411, 413, 414, 415, 416, 417, and 418 are displayed on the display screen 401, respectively. In this embodiment, the content image indicates a thumbnail image of a plurality of moving image contents. This content image has a one-to-one correspondence with the moving image content stored in the content storage unit 121, and the moving image content to be viewed can be specified by designating the content image. As described above, the content stored in the content storage unit 121 is not limited to moving image content.

  In FIG. 4, a left arrow display 402 indicates that a positive acceleration is applied to the scroll speed to the left by placing the mouse pointer 404 on the left side of the center line drawn in the vertical direction on the display screen 401. . The right arrow display 403 indicates that a positive acceleration is given to the scrolling speed in the right direction by placing the mouse pointer 404 on the right side of the center line drawn in the vertical direction on the display screen 401.

  Also, as shown in the content image 411 of FIG. 4, the channel number of the moving image content is arranged at the top of the content image. The channel number is a number for identifying the provider of moving image content. In the content image, a representative image 412 of the moving image content is arranged below the channel number. Thus, each content image has a channel number and a representative image of moving image content. At the start of scroll display, the display order of the content images is arranged in the order stored in the content storage unit 121, for example. However, the configuration of the content image is not limited to this. Further, the order of displayed content images may be, for example, the order of channel numbers.

  Also, the moving image content corresponding to the content image 411 in FIG. 4 has “sport”, “sumo”, “2006/3/3”, and “12: 00-15: 00” as attribute information. “Sports” and “sumo” are attribute information used to classify content according to program categories. “Sports” is attribute information of a classification level one level higher than “sumo”. “2006/3/3” is attribute information indicating the past broadcast date of the moving image content corresponding to the content image 411, and “12: 00-15: 00” is the past moving image content. This is attribute information indicating the broadcast time. These pieces of attribute information are attribute information used for classifying content according to the past broadcast date and past broadcast time. The channel number can also be used as attribute information for classifying content. FIG. 8A shows an example of attribute information held by the moving image content corresponding to each content image displayed in FIG. That is, in the present embodiment, the attribute information shown in the attribute information 1 and the attribute information 2 in FIG. 8A is attribute information used for classifying content by program category. Further, the attribute information 3 is attribute information used for classifying the content by the past broadcast date, and the attribute information 4 is attribute information used for classifying the content by the past broadcast time. Each content image is displayed in the order of the content image numbers in FIG.

  In this embodiment, an example in which seven content images are scrolled and displayed is shown, but the number of content images is not limited to this. Further, in this embodiment, an example is shown in which content images of seven contents that are candidates for content to be viewed are always displayed. However, a configuration may be adopted in which displayed content images are switched as appropriate by scrolling.

  In the state “1. start” in FIG. 3, when an operation (302) for increasing the scrolling speed is performed from the operation unit 120, the scrolling speed is increased. In the present embodiment, the scroll speed is gradually increased by an operation for increasing the scroll speed. The display screen during execution of this operation is, for example, “2. Operation” in FIG. In the present embodiment, the scrolling speed is indicated by the length of the arrow arranged at the top of the display screen 401. That is, it can be seen that the scroll speed is increased because the “2. operation” arrow 501 is longer than the length of the “1. start” arrow 405 in FIG. This arrow is fixedly displayed at the upper center of the screen regardless of scrolling of the content image.

  When the boundary determination unit 104 determines that the scrolling speed has exceeded the first predetermined value shown in FIG. 2, the display control unit 105 displays the classification candidate list (303). The display screen at this time is as shown in “3. Response” in FIG. As shown in the figure, the classification candidate list in this embodiment includes “program category”, “past broadcast date”, and “past broadcast time”. The user can select a plurality of content classification methods by selecting any item from the displayed classification candidate list using the mouse (304). Here, as shown in “4. Operation” in FIG. 5, it is assumed that “program category” is selected from the items displayed in the classification candidate list using the mouse pointer 701. As described above, according to the present embodiment, the content classification method can be selected in response to the scroll speed reaching the first predetermined value. By displaying the classification candidate list in this way, it is possible to select a classification method according to the user's preference according to the speed of scrolling. However, a classification method may be set in advance, or for example, classification may be performed using a classification method used in the past.

  When the classification method is selected in 304 of FIG. 3, the display control unit 105 switches the classification level. That is, in this form, the display is switched from the content image to the classification information image (305). The display screen at this time is as shown in “5. Response” in FIG. As shown in the figure, the display control unit 105 classifies the plurality of contents using the attribute information 2 in FIG. 7 in response to the selection of “program category” as the plurality of content classification method, The classification information image is displayed. Note that the attribute information shown in the attribute information 2 is attribute information used for classifying content by program category as described above. The attribute information 1 is also attribute information for classifying content according to the category of the program. However, since the attribute information is one level of classification information that is roughly one level higher than the attribute information of the attribute information 2, the attribute information 2 Classification is performed according to attribute information. That is, when an operation for further increasing the scrolling speed is performed from this state, the content is classified using the attribute information 1, but the description thereof is omitted.

  Further, as shown in “5. Response” in FIG. 5, the length of the arrow 807 indicating the scrolling speed is shortened. This indicates that the display control unit 105 reduces the scrolling speed in response to the increase in the classification level. As described above, the state where the content image is displayed is the lowest classification level, and the classification level is raised by switching the display from the content image to the classification information image. The reason why the scrolling speed is reduced in accordance with the increase in the classification level is as follows. That is, when the first predetermined value is set so fast that the contents of each displayed image cannot be confirmed, the classification information indicated by the newly displayed classification information image may not be confirmed. . Therefore, when the classification level is increased, the display control unit 105 of the present embodiment decreases the scrolling speed so that it is easy to confirm the contents of the newly displayed classification information image. When the classification level is increased, the number of classification information images displayed after switching is reduced compared to the number of content images before switching.

  Further, in “5. Response” in FIG. 5, classification information images of “baseball”, “quiz”, and “weather forecast” are displayed, but other classification information images (“triathlon” “domestic news”) are scrolled. Is also displayed as appropriate.

  After switching the classification level in 305 of FIG. 3, if an operation for reducing the scrolling speed is performed from the operation unit 120 (306), the display screen 401 becomes like “6. Operation” in FIG. 5. That is, the arrow 901 indicating the scrolling speed is further shorter than the arrow 807 of “5. Response”, indicating that the scrolling speed is slow. Further, since the classification method is selected, the classification candidate list is not displayed. Thus, the complexity of the display screen can be reduced by not displaying the classification candidate list after selecting the classification method. Further, it is possible to prevent a new classification method from being selected due to an erroneous operation by the user. However, while the classification information image is displayed, the classification candidate list may be displayed so that the content classification method can be changed. In this way, for example, when the user selects the classification method incorrectly, the desired classification method can be set again.

  If it is determined that the scroll speed has reached the second predetermined value due to the reduction of the scroll speed in 306, processing for lowering the classification level is performed (307). The display screen at this time is as shown in “7. Response” in FIG. As shown in the figure, content images are displayed. The display order of the displayed content images is different from the display order of the content images in “1.start” in FIG. That is, the display order of the content images displayed in response to the slow scrolling is sorted according to the classification method selected in 304 of FIG.

  FIG. 8B shows the display order and attribute information of each content image displayed in “7. Response” in FIG. As shown in the figure, the display order of the content images in FIGS. 8A and 8B is different. That is, in this embodiment, after the content is classified by the classification method of “program category”, the content image is sorted by the attribute information 2 indicating the program category by switching from the classification information image to the display of the content image. ing.

  In this embodiment, sorting is performed according to the category of the program selected as the content classification method. However, for content having attribute information indicating the category of the same program, attribute information 3 (past broadcast date) Are sorted in the oldest order. That is, the display order of the content images 411 and 414 having the same attribute information 2 is sorted so that the content image 411 with earlier broadcast date is displayed first. Further, the display order of the content images 413 and 416 having the same attribute information 2 is sorted so that the content image 413 with the earlier broadcast date is displayed first. In this way, by sorting using other attribute information, it is possible to make it easier to select content to be viewed. However, in this embodiment, other attribute information such as the channel number and the time stored in the content storage unit 121 may be used instead of the attribute information 3.

  Further, as shown in “7. Response” in FIG. 6, the length of the arrow 1001 indicating the scrolling speed is longer than the arrow 901 of “6. Operation”. This indicates that the display control unit 105 increases the scrolling speed in response to the lowering of the classification level. The reason for this is as follows. That is, when the second predetermined value is set so late that, for example, scrolling is likely to stop, the user may want to quickly confirm the newly displayed content image or the classification information image whose classification level has been lowered. is there. Therefore, when the classification level is lowered, the display control unit 105 according to the present embodiment increases the scrolling speed so that the content image newly displayed or the content of the classification information image can be confirmed quickly.

  Further, the display screen when the operation for further reducing the scrolling speed is performed from the state 307 in FIG. 3 is as shown in “8.end” in FIG. As shown in the figure, it can be seen that the arrow 1101 indicating the scroll speed is shortened, and the scroll speed is slow. Thus, by displaying the content images sorted according to the selected classification method, the user can more efficiently select the moving image content that the user wants to view.

  As described above, the display control apparatus 100 according to the present embodiment selects a classification method candidate for classifying a plurality of contents in response to the scroll speed of the content image reaching the first predetermined value. The indicated classification candidate list is displayed. Then, according to the selected classification method, the contents are classified by classification information corresponding to a plurality of contents, and the classification information image is displayed. Thereafter, an operation for further increasing the scrolling speed is performed, and when the scrolling speed reaches a predetermined value, the content is classified with classification information having a higher classification level in the classification method that has already been selected. The classification information image is displayed. The predetermined value may be different depending on the current classification level, or may be a constant value (first predetermined value).

  Thereafter, an operation for decreasing the scrolling speed is performed, and when the scrolling speed reaches the second predetermined value, the classification level of the displayed classification information image is lowered. If the current classification level is one level higher than the lowest classification level, the display is switched to the display of the content image by the process of lowering the classification level. Thus, the display control apparatus 100 according to the present embodiment switches the classification level based on the scrolling speed. Further, the display order of the classification information image or content image displayed by lowering the classification level is sorted by the attribute information used for classification.

  In this way, it is possible to select content to be viewed from a plurality of contents more efficiently. That is, the classification level can be switched in conjunction with an instruction to increase or decrease the scrolling speed. Further, by adopting a configuration in which the content classification method is selected in response to the scroll speed exceeding a predetermined value, the content images can be sorted in the order according to the desired classification method.

<Embodiment 2>
Next, a second embodiment of the present invention will be described focusing on differences from the first embodiment.

  In the first embodiment, the classification candidate list is displayed and the classification method is selected in response to the scroll speed reaching the first predetermined value. However, in this embodiment, the classification method is determined in advance. The case will be described. In this embodiment, the classification level is immediately switched according to a predetermined classification method in response to the scroll speed reaching a predetermined value.

  The relationship between the scrolling speed at each time and the switching of the classification level in this embodiment will be described with reference to FIG.

  FIG. 7 is a diagram showing the change of the classification level performed according to the scrolling speed together with the information on the passage of time. In FIG. 7, the vertical axis 1201 indicates the scrolling speed, and the horizontal axis 1211 indicates the time.

  An initial state 1212 indicates a state immediately before content scrolling is performed. In this state, unclassified content images are displayed. In this state, when the user places the mouse pointer 404 on the right side of the display screen 401, for example, the speed of scrolling to the right increases (1220). The display screen in 1220 corresponds to a transition from the state of “1. start” in FIG. 4 to “2. operation”, for example. In the first embodiment, the classification candidate list is displayed when the scrolling speed reaches the first predetermined value, but is not displayed in the present embodiment.

  The display control unit 105 switches the content classification level and the scrolling speed at time A (1213) when the scrolling speed reaches a predetermined value A (1202). In the present embodiment, the display control unit 105 switches from the state where the content image is displayed (minimum classification level) to the state where the classification information image is displayed. This classification information image represents the classification of content images (baseball, quiz, weather forecast, domestic news, etc.). Further, the display screen at time A (1213) is as shown in “5. Response” in FIG. However, in this embodiment, the classification candidate list (classification method candidates 601, 602, 603) is not displayed.

  Next, during the period from time A to time B, the user increases the scrolling speed of the content in order to confirm the classification information image, for example (1221). Then, from time B to time C, the user decreases the scrolling speed of the classification information image (1222). As a result, at time C, the scrolling speed reaches a predetermined value B (1205). The predetermined value B (1205) corresponds to the second predetermined value in FIG. At time C (1215), the display control unit 105 switches the classification level and the scrolling speed. That is, the display control unit 105 switches the display from the classification information image to the content image at time C (1215), and increases the scrolling speed. The display screen at this time is, for example, “7. Response” in FIG. The content images displayed at this time are sorted according to a predetermined classification method. The order in which the content images are displayed is the order of the classification corresponding to the classification information image displayed from time A to time C (in the example of FIG. 4, the order is baseball, quiz, weather forecast, domestic news). . When the scrolling speed is reduced from time C (1215) (1223), scrolling of the sorted content image is eventually stopped (1216). However, if the content image is selected before the scrolling stops, the content corresponding to the content image may be displayed. The display screen in 1223 corresponds to, for example, a transition from the state of “7. start” in FIG. 6 to “8. end”.

  In this embodiment, a default content classification method is set in advance, and when the scrolling speed exceeds a predetermined value, the content is classified according to the classification information according to the set classification method. Alternatively, the classification method may be determined in advance by another method. That is, for example, a content classification method used in the past can be used. In this case, for example, when scroll display is started, content images are displayed in the order stored in the channel number or content storage unit 121. After that, when the scrolling speed exceeds a predetermined value, the contents are classified according to a preset classification method, and a classification information image is displayed. In this way, the trouble of selecting a classification method can be simplified.

  In addition, the image generation unit 103 of this embodiment may generate a classification information image according to a preset classification method when the display control unit 105 displays the content image. Then, for example, when it is determined that the scroll speed has reached the first predetermined value, the display control unit 105 may display the classification information image generated by the image generation unit 103 in advance. In this way, it is possible to shorten the time from when the user wants to display the classification information image until it is actually displayed.

<Other embodiments>
In the first and second embodiments, the classification level is lowered by reducing the scrolling speed, and the content to be viewed can be selected at the lowest classification level. However, it is also possible to display a classification information image or a content image at a lower classification level corresponding to the classification information of the classification information image selected from the plurality of displayed classification information images. That is, when the display control unit 105 receives an input signal for determining the classification information in a state where the classification information (classification information image) is displayed, the display control unit 105 displays the content (content image) corresponding to the determined classification information. Let For example, when baseball is selected, content corresponding to the classification information “baseball” is displayed. In this way, when the attribute information of the content to be viewed is known in advance, the content to be viewed can be selected more efficiently. In this case, the classification information image that has not been selected may be deleted from the display screen. In this way, content that is highly likely to be selected can be left on the display screen, so that it is possible to select content that the user wants to view more efficiently.

  In the first and second embodiments, the classification levels for all contents are switched. However, the present invention is not limited to this, and the classification levels for some contents may be switched. That is, for example, when “sports” is selected from the classification candidate list, content related to sports is classified and its classification information image is displayed. That is, for example, in a classification level one level higher than the lowest classification level, for example, “high school baseball”, “professional baseball”, “high school soccer”, “professional soccer”, etc. are displayed, and if the classification level is further increased, “baseball” “soccer” Is displayed. Then, for content not related to sports, the content image may be displayed, or the display may be deleted. By deleting contents not related to the selected classification method, it is possible to select contents to be viewed more efficiently.

  On the other hand, regarding the content related to the selected classification method, the classification information image may be displayed, and the display of the content image of the unrelated content may be left. In this way, for example, when searching for content to be viewed using the erasing method, content images of content that is determined not to be viewed can be combined into classification information images. Therefore, it is possible to more efficiently select content to be viewed.

  Moreover, although Embodiment 1 and 2 demonstrated the case where the direction of a scroll was right direction and left direction, it is not restricted to this. That is, the scroll direction may be upward, downward, or diagonal.

  In the first and second embodiments, the content classification method has been described with examples of the program category, the broadcast start time, and the like. However, the present invention is not limited to these methods. Other classification methods include, for example, broadcasting stations, recording locations, performers, broadcast times, broadcast dates, seasons of recording dates, content fields (eg, politics, economy, IT, home), etc. You may make it classify | categorize a content by combining suitably.

  The scroll information acquisition unit 102 according to the first and second embodiments acquires the scroll speed based on the scroll operation information input from the operation unit 120. However, the scroll information acquisition unit 102 acquires the scroll speed from the display unit 122. It may be. That is, for example, when the display control device 100 and the display unit 122 are separate devices, the scroll information acquisition unit 102 inquires the display unit 122 about the scrolling speed, and acquires the scrolling speed based on the response. You may make it do.

  Moreover, although Embodiment 1 and 2 demonstrated switching the classification level based on the speed of scroll, it is not restricted to this. That is, the classification level may be switched using the magnitude of the change in scroll speed instead of the scroll speed. (That is, the display control unit 105 may display classification information (classification information images) of a plurality of contents when the amount of change per unit time of the scrolling speed reaches a predetermined value. For example, when the amount of change in the scrolling speed varies depending on the coordinate position where the mouse pointer 404 is placed, the scroll information acquisition unit 102 changes the classification level according to the coordinate information indicated by the mouse pointer 404. In this way, the classification level can be changed without acquiring information about the scrolling speed.

  Moreover, although Embodiment 1 and 2 demonstrated the example which switches the display of a content image to the display of a classification information image based on the speed of scroll, it is not restricted to this example. For example, the display control unit 105 may display the result of sorting the content images according to the scrolling speed. That is, the image generation unit 103 acquires attribute information of a plurality of contents stored in the content storage unit 121 from the attribute acquisition unit 101, and sorts (classifies) the plurality of contents. In step S209, the display control unit 105 displays the sorted content image (classification result).

  In addition, when displaying the result of sorting the content images according to the speed of scrolling, a plurality of content images are enclosed for each classification so that the content is classified together with the sorted content images. A frame may be displayed. That is, the image generation unit 103 generates an image of a frame for indicating that the content image is classified in S208. In step S <b> 209, the display control unit 105 displays the sorted content image and the frame image generated by the image generation unit 103. Thus, if the display of the content image is continued and the content classification is indicated by the frame, the content can be confirmed even in the state where the content is classified.
