[0003] [Patent Document 1] JP 2012-249143 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the technology described in Patent Document 1, if there is a portion of the image that has not changed for a predetermined period of time, it is determined that the time is displayed, and if there is no portion of the image that has not changed, it is determined that the time is not displayed. However, if there is an unchanged portion in the image that is not a time display, it may be erroneously determined that the time is displayed when in fact the time is not displayed, and the time may not be displayed appropriately. As such, there is room for improvement in the time display on television broadcast display devices.

[0005] The present invention has been made in consideration of the above, and aims to provide a television broadcast display control device, a television broadcast display control method, and a program that can display the time more appropriately. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, embodiments of a television broadcast display control device, a television broadcast display control method, and a program according to the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiments.

[0012] [First embodiment] (TV broadcast display device) FIG. 1 is a block diagram showing an example of the configuration of a television broadcast display device 1 including a control device 40 which is a television broadcast display control device according to the first embodiment. The television broadcast display device 1 is a display device that displays television broadcasts. The television broadcast display device 1 is implemented, for example, in an electronic device mounted on a vehicle or a portable electronic device. In this embodiment, the television broadcast display device 1 is mounted on a vehicle. The television broadcast display device 1 includes an antenna 11, a tuner 12, a separation unit 13, a GNSS (Global Navigation Satellite System) receiving unit 21, a clock unit 22, a display unit 31, a speaker 32, and a television broadcast display control device (hereinafter referred to as a "control device") 40. The television broadcast display device 1 may further include a program data storage unit 33.

[0013] The television broadcast display device 1 shares the display unit 31 with another system. In this embodiment, the television broadcast display device 1 shares the display unit 31 with another system mounted in a vehicle, such as a navigation system. The other system has a function of displaying the current time on the display unit 31.

[0014] The antenna 11 receives broadcast data of a television broadcast. The broadcast data includes broadcast video data and broadcast audio data. The broadcast data may include additional data such as program data. The antenna 11 outputs the received broadcast data to the tuner 12.

[0015] The tuner 12 selects and receives the broadcast data received by the antenna 11. The tuner 12 outputs the selected broadcast data to the separation unit 13.

[0016] The separation unit 13 separates the broadcast data received by the tuner 12 into broadcast video data and broadcast audio data. The separation unit 13 may separate program data from the broadcast data received by the tuner 12. The separation unit 13 outputs the broadcast video data and the broadcast audio data to the control device 40. The separation unit 13 may output the program data to the control device 40.

[0017] The GNSS receiver 21 is configured with a GNSS receiver that receives GNSS signals from GNSS satellites. In this embodiment, the GNSS receiver 21 is implemented as a function of the navigation system. The GNSS receiver 21 outputs the received GNSS signals to the position information acquisition unit 41 of the control device 40.

[0018] The clock unit 22 is a clock that keeps track of the current time. In this embodiment, the clock unit 22 is implemented as a function of the navigation system. The clock unit 22 outputs time information of the current time to a time information acquisition unit 42 of the control device 40.

[0019] The display unit 31 is a display device shared with a navigation system. The display unit 31 is a display including, for example, a liquid crystal display (LCD) or an organic EL (Electro-Luminescence) display. The display unit 31 can display broadcast video data of a television broadcast based on a video signal output from the display control unit 52 of the control device 40. The display unit 31 can display map video data by the navigation system.

[0020] The speaker 32 is a speaker shared with the navigation system, and outputs broadcast audio data of a television broadcast based on an audio signal output from the audio output control unit 53 of the control device 40.

[0021] The program data storage unit 33 is a storage device that stores program data. The program data includes data such as the broadcast station, broadcast time, genre, and title of the program. The program data may include program guide data called EPG (Electronic Program Guide). The program data is stored according to the user's current location. The program data storage unit 33 is a storage device such as a semiconductor memory element such as a ROM (Read Only Memory) or a flash memory, or an external storage device via a network.

[0022] (Control device) The control device 40 is an arithmetic processing device constituted by, for example, a CPU (Central Processing Unit) and the like. The control device 40 may be constituted by one or more devices. The control device 40 executes instructions contained in a program stored in a storage unit (not shown). If the broadcast video data includes a time display, the control device 40 stops the display of the time by the navigation system. If the broadcast video data does not include a time display, the control device 40 displays the time by the navigation system. The control device 40 determines whether or not the broadcast video data includes a time display, and switches between displaying and not displaying the time display by the navigation system.

[0023] The control device 40 includes a position information acquisition unit 41 , a time information acquisition unit 42 , a display determination unit 43 , a composite image generation unit 51 , a display control unit 52 , and an audio output control unit 53 .

[0024] The location information acquisition unit 41 acquires location information indicating the current location of the user from the GNSS receiving unit 21 .

[0025] The time information acquisition unit 42 acquires time information indicating the current time from the clock unit 22 .

[0026] The display determination unit 43 determines, based on the time information acquired by the time information acquisition unit 42, whether or not the broadcast video data has a time display at the current time.

[0027] For example, in the morning or in the evening when people return home, the broadcast video data often includes a time display. Such time display periods are stored in a storage unit (not shown).

[0028] For example, when the current time is in a time period in which the broadcast video data has a time display, the display determination unit 43 determines that the time display is present. For example, the display determination unit 43 determines that the time display is present in a time period from early morning to around 9:00 a.m. or from 4:00 p.m. to 7:00 p.m.

[0029] The display determination unit 43 may determine whether or not a time display is present in the broadcast video data at the user's current location and current time based on the location information acquired by the location information acquisition unit 41 and the time information acquired by the time information acquisition unit 42.

[0030] For example, in area A, the time is not displayed in the broadcast video data during any time period, but in area B, the time is displayed in the broadcast video data during the morning time period or the time period from evening to night when people return home. In this case, when the user is in area A, the display determination unit 43 determines that the broadcast video data does not display the time. When the user is in area B and it is the morning time period or the time period from evening to night when people return home, the display determination unit 43 determines that the broadcast video data displays the time.

[0031] The display determination unit 43 may determine whether or not the broadcast video data includes a time display based on the location information acquired by the location information acquisition unit 41, the time information acquired by the time information acquisition unit 42, and the program data, which is detailed information about the program and is received together with the broadcast video data.

[0032] The display determination unit 43 may determine whether or not a time display is present based on at least one of the genre and title of the program included in the program data. More specifically, the display determination unit 43 may determine whether or not a time display is present based on the genre of the program. For example, when the genre of the program is a news program, the display determination unit 43 determines that a time display is present. For example, when the genre of the program is a drama, anime, or movie program, the display determination unit 43 determines that a time display is not present. The display determination unit 43 may determine whether or not a time display is present based on the title of the program. For example, when the program is a program with a predetermined title, the display determination unit 43 determines that a time display is present. The display determination unit 43 may determine whether or not a time display is present based on time information and the genre of the program. For example, when the program is a news program or a morning information program from early morning to around 9:00 a.m. or from 4:00 p.m. to 7:00 p.m., the display determination unit 43 determines that a time display is present. For example, if the program is a drama, anime, or movie program in a time slot other than those mentioned above, the display determination unit 43 determines that there is no time display.

[0033] The display determination unit 43 may determine whether or not the broadcast video data includes a time display based on the position information acquired by the position information acquisition unit 41, the time information acquired by the time information acquisition unit 42, and the program data stored in the program data storage unit 33. The display determination unit 43 may determine whether or not the broadcast video data includes a time display based on the program data according to the user's position information and the current time.

[0034] The display determination unit 43 may determine whether or not a time display is present based on at least one of the genre and the title included in the program data corresponding to the user's location information and the current time. More specifically, the display determination unit 43 may determine whether or not a time display is present based on the current time and the genre. For example, when the current time is in a time zone during which a news program is broadcast, the display determination unit 43 determines that a time display is present. For example, when the current time is in a time zone during which a drama, anime, or movie is broadcast, the display determination unit 43 determines that a time display is not present.

[0035] The composite video generating unit 51 generates composite video data by combining the broadcast video data with the time information acquired by the time information acquiring unit 42. More specifically, when the display determining unit 43 determines that there is no time display, the composite video generating unit 46 generates composite video data by combining the time information. The composite video generating unit 51 combines the time information in a position that does not reduce the visibility of the broadcast video data, such as the upper right, lower right, upper left, or lower left of the broadcast video data. In this embodiment, the composite video generating unit 51 combines the time information in the lower right of the broadcast video data.

[0036] The composite video data may be synthesized with time information that specifies at least one of font, font size, color, and display position. For example, the composite video data may be synthesized with time information that is the same as or similar to the time display displayed in the immediately preceding broadcast video data in at least one of font, font size, color, and display position.

[0037] 2 is a diagram showing an example of broadcast video data 101, in which the time of a television broadcast is displayed. A time display 103 is provided in an upper left portion 102 of the broadcast video data 101. No time display is provided in a lower right portion 104 of the broadcast video data 101.

[0038] Fig. 3 is a diagram showing an example of the composite video data 110, in which the time of the navigation system is displayed. There is no time display in the upper left part 102 of the broadcast video data 101 shown in Fig. 3. In the composite video data 110, time information 105 acquired by the time information acquisition unit 42 is synthesized in the lower right part 104 of the broadcast video data 101. By making the display position of the time display of the navigation system and the display position of the time display of the broadcast video data 101 different, it is possible to avoid the time displays overlapping and reducing visibility.

[0039] The display control unit 52 causes the received broadcast video data to be displayed on the display unit 31. The display control unit 52 causes the composite video data to be displayed. The display control unit 52 may display map video data using a navigation system.

[0040] The audio output control unit 53 causes the speaker 32 to output the broadcast audio data of the received television broadcast.

[0041] (Processing in the control device) Next, the method and action of the processing performed by the control device 40 will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the processing performed by the control device 40 according to the first embodiment. While the television broadcast display device 1 is running and broadcast video data is being displayed on the display unit 31, the processing of the flowchart shown in Fig. 4 is repeatedly executed.

[0042] The control device 40 acquires the current location (step S101). More specifically, the control device 40 acquires location information of the user's current location by the location information acquisition unit 41. The control device 40 proceeds to step S102.

[0043] The control device 40 judges whether or not the broadcast video data has a time display (step S102). More specifically, the control device 40 judges whether or not the broadcast video data has a time display by the display judgment unit 43 based on the time information acquired by the time information acquisition unit 42. For example, the display judgment unit 43 judges that the broadcast video data has a time display when the current time is in a time zone in which the broadcast video data has a time display. For example, the display judgment unit 43 judges that the broadcast video data does not have a time display when the current time is in a time zone in which the broadcast video data does not have a time display. The display judgment unit 43 may judge whether or not the broadcast video data has a time display at the user's current location and current time based on the position information and time information. The display judgment unit 43 may judge whether or not the broadcast video data has a time display based on the position information, the time information, and the program data that is detailed information about the program. If the display judgment unit 43 judges that the broadcast video data has a time display (Yes in step S102), the control device 40 proceeds to step S103. When the display determination unit 43 of the control device 40 determines that the time display is not present (No in step S102), the control device 40 proceeds to step S104.

[0044] When it is determined that the time is displayed (Yes in step S102), the control device 40 hides the time from the navigation system (step S103). More specifically, the control device 40 causes the display control unit 52 to display the broadcast video data on the display unit 31. The control device 40 causes the display control unit 52 to display, for example, the broadcast video data 101 shown in FIG. 2 on the display unit 31. The control device 40 ends the process.

[0045] If it is not determined that the time is to be displayed (No in step S102), the control device 40 displays the time from the navigation system (step S104). More specifically, the control device 40 generates composite video data by combining the broadcast video data 101 with the time information acquired by the time information acquisition unit 42 using the composite video generation unit 51. The control device 40 then causes the display control unit 52 to display the composite video data on the display unit 31. The control device 40 causes the display control unit 52 to display, for example, the composite video data 110 shown in FIG. 3 on the display unit 31. The control device 40 ends the process.

[0046] In the navigation system, if the user sets the time display to "no display (OFF)", the process of the above flowchart is not applied.

[0047] In addition, if the user has set the time display to "display (ON)" in the navigation system, after the time display on the navigation system is hidden in step S103, if it is determined that the time display on the broadcast video data has disappeared (No in step S102), the time display on the navigation system will be restored.

[0048] In this way, it is determined whether or not the broadcast video data has a time display based on the time information. If it is determined that the broadcast video data has a time display, the navigation system stops displaying the time. If it is determined that the broadcast video data does not have a time display, the navigation system displays the time.

[0049] (effect) As described above, in this embodiment, it is determined whether or not the broadcast video data has a time display based on the time information. If it is determined that the broadcast video data has a time display, the display of the time by the navigation system can be stopped. In this embodiment, if it is determined that the broadcast video data does not have a time display, the navigation system can display the time. In this embodiment, it is possible to determine whether or not the broadcast video data has a time display, and to switch between displaying and not displaying the time display by the navigation system. According to this embodiment, it is possible to restrict double display of the time on the display unit 31. By restricting double display as in this embodiment, it is possible to prevent the user from feeling annoyed or uncomfortable about the time display. In this way, this embodiment is able to display the time appropriately.

[0050] In this embodiment, whether or not the broadcast video data has a time display is determined based on the position information and the current time, making it possible to more appropriately determine whether or not the time display is present.

[0051] In this embodiment, it is determined whether or not the broadcast video data includes a time display based on the position information, the current time, and the program data, making it possible to more appropriately determine whether or not the time display is included.

[0052] This embodiment makes it possible to easily determine in a short amount of time whether or not the time is displayed.

[0053] In this embodiment, time information that is the same as or similar to the time display displayed in the immediately preceding broadcast video data in at least one of font, font size, color, and display position is synthesized. When the time display by the navigation system is switched from hidden to displayed, this embodiment can display the time in a manner that does not impair the user's visibility.

[0054] [Second embodiment] A television broadcast display device 1A having a control device 40A according to this embodiment will be described with reference to Figs. 5 and 6. Fig. 5 is a block diagram showing an example of the configuration of the television broadcast display device 1A including the control device 40A according to a second embodiment. Fig. 6 is a flowchart showing an example of processing performed by the control device 40A according to the second embodiment. The television broadcast display device 1A has a basic configuration similar to that of the television broadcast display device 1 of the first embodiment. In the following description, components similar to those of the television broadcast display device 1 are given the same or corresponding reference symbols, and detailed description thereof will be omitted. The control device 40A of this embodiment differs from the first embodiment in that it has a recognition unit 44A and in the processing in the display determination unit 43A.

[0055] The time display included in the broadcast video data is a character string including numbers indicating the hour and minute of the time, such as "xxx:xxx" or "xxx:xxx". The time display may include 12-hour and 24-hour displays, such as "15:00" or "PM3:00". The time display may include characters indicating morning and afternoon, such as "AM" or "PM". The time display includes horizontal writing, vertical writing, and analog clock display. The time display may include hours, minutes, and seconds, such as "xxx:xxx:xxx" or "xxx:xxx:xxx". When the time display includes hours and minutes, the time display is updated every minute (60 seconds). When the time display includes hours, minutes, and seconds, the time display is updated every second.

[0056] The time display included in the broadcast video data may be, for example, a graphic representation of an analog clock. In the case of an analog clock including hour and minute hands indicating hours and minutes, the time display is updated every minute. In the case of an analog clock including a second hand, the time display is updated every second.

[0057] The recognition unit 44A recognizes characters indicating the time from the broadcast video data. More specifically, the recognition unit 44A acquires the broadcast video data. Then, the recognition unit 44A performs character recognition processing, such as OCR (Optical Character Reader) processing, on the acquired broadcast video data to extract character information indicating the time. The recognition unit 44A outputs the recognized character information to the display determination unit 43A. The character information recognized by the recognition unit 44A is, for example, "xxx:xxx", "xxx:xxx", "xxx:xxx:xxx", "xxx:xxx:xxx", and so on.

[0058] The recognition unit 44A recognizes a graphic representing an analog clock from the broadcast video data. More specifically, the recognition unit 44A acquires the broadcast video data. Then, the recognition unit 44A performs image recognition processing on the acquired broadcast video data to recognize the graphic of the analog clock. The recognition unit 44A outputs the recognized graphic information to the display determination unit 43A.

[0059] The display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes every predetermined time. In this embodiment, when the same time display continues for a predetermined time in the broadcast video data, the broadcast video data is determined to have a time display. For example, when the time display includes hours and minutes, the time display changes every minute. In this case, the display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes every minute. When the time display includes hours, minutes, and seconds, the time display changes every second. In this case, the display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes every second. The display determination unit 43A determines that the broadcast video data has a time display when the broadcast video data includes a time display that changes every second. For example, when a character string such as "xx:xx" or "xx:xx" changes numbers every minute or every second, the display determination unit 43A determines that the broadcast video data has a time display. Display determination unit 43A determines that there is a time display when the position of the hands on the analog clock graphic changes over one minute or one second.

[0060] For example, if a flipboard used in an information program has characters or figures written on it, the characters or figures do not change even after a predetermined time has passed. Also, if a character string indicating the time is written on a flipboard or the background of a broadcast studio, the character string does not change even after a predetermined time has passed, unlike the current time. If the broadcast video data includes a time display that does not change over a predetermined time, the display determination unit 43A determines that the broadcast video data does not have a time display.

[0061] For example, when the channel is changed, or when a program ends and it is time to switch to the next program, a counter, which will be described later, is reset and counting the predetermined time period is started anew.

[0062] Next, the method and action of the process performed by the control device 40A will be described with reference to Fig. 6. The process in Fig. 6 is executed when step S103 in the flowchart shown in Fig. 4 is executed. The description will be given assuming that the predetermined time is one minute (60 seconds) and the predetermined time interval is one second.

[0063] The control device 40A resets the counter (step S111). The control device 40A proceeds to step S112.

[0064] The control device 40A temporarily stores the received broadcast video data (step S112). The control device 40A temporarily stores the broadcast video data in a memory at a predetermined time interval, for example, at one second intervals. The control device 40A proceeds to step S113.

[0065] The control device 40A recognizes the broadcast video data (step S113). The control device 40A recognizes the time display of the received broadcast video data by the recognition unit 44A. The control device 40A stores the recognition result in association with the broadcast video data stored in the memory in step S112. The control device 40A proceeds to step S114.

[0066] The control device 40A judges whether or not the same time display as the previous time is present (step S114). The control device 40A uses the display judgment unit 43A to compare the recognition result of the broadcast video data in the current process stored in the memory with the recognition result of the broadcast video data in the previous process. The current process is the latest process among the processes at a predetermined time interval. The control device 40A compares character strings such as "XXX:XX" and "XX hours XX minutes" recognized from the current and previous broadcast video data. Alternatively, the control device 40A compares the position of the hands of an analog clock figure recognized from the current and previous broadcast video data. If the display judgment unit 43A judges that the same time display as the previous time is present (Yes in step S114), the control device 40A proceeds to step S115. If the display judgment unit 43A does not judge that the same time display as the previous time is present (No in step S114), the control device 40A proceeds to step S118.

[0067] If it is determined that the same time display as the previous time is present (Yes in step S114), the control device 40A increments the counter by "1" (step S115). The increment of the counter is set corresponding to the predetermined time interval in step S112. For example, if the predetermined time interval is one second, the counter is incremented by "1".

[0068] The control device 40A determines whether the counter is equal to or greater than 59 (step S116). The control device 40A determines whether the same time display has continued for a predetermined time. If the predetermined time is one minute (60 seconds), the counter is at "59" when the same time display has continued for one minute. If the control device 40A determines that the counter is equal to or greater than 59 (Yes in step S116), the control device 40A proceeds to step S117. In this case, the same time display has continued for a predetermined time, for example, 60 seconds. If the control device 40A does not determine that the counter is equal to or greater than 59 (No in step S116), the control device 40A executes the process of step S112 again. In this case, the same time display has not continued for a predetermined time, for example, 60 seconds.

[0069] If it is determined that the counter is 59 or more (Yes in step S116), the control device 40A hides the time displayed by the navigation system (step S117). If the same time display continues for a predetermined time, for example, 60 seconds, the control device 40A hides the time display by the navigation system. More specifically, the control device 40A causes the display control unit 52 to display the broadcast video data on the display unit 31. The control device 40A causes the display control unit 52 to display, for example, the broadcast video data 101 shown in FIG. 2 on the display unit 31. The control device 40A ends the process.

[0070] If it is not determined that the same time display as the previous time is present (No in step S114), the control device 40A resets the counter (step S118). If the same time display has not continued for a predetermined time, for example, 60 seconds, the counter is reset. The control device 40A executes the process of step S112 again.

[0071] If the broadcast video data has a time display, the result in step S116 becomes Yes when the same time display continues for one minute for the first time. For example, if processing is started between 7:25:00 and 7:25:59, the counter becomes "59" at 7:25:59. In this case, from "7:26", only the time display of the broadcast video data 101 is displayed. For example, if processing is started between 7:26:00 and 7:26:59, the counter becomes "59" at 7:26:59. In this case, from "7:27", only the time display of the broadcast video data 101 is displayed.

[0072] If the predetermined time interval is 5 seconds, the counter is incremented by 5 in step S114, and then it is determined in step S116 whether the counter is 55 or greater.

[0073] For example, when a character string indicating the time is written on a flip board or the background of a broadcast studio, the character string may move or disappear from the display unit 31. For this reason, it is considered that it is rare for the character string indicating the time on a flip board or the like to be determined to continue to display the same time for a predetermined period of time, for example, 60 seconds.

[0074] In this manner, if the broadcast video data includes a time display that changes at predetermined intervals, it is determined that the broadcast video data includes a time display.

[0075] As described above, in this embodiment, if the broadcast video data includes a time display that changes over a predetermined period of time, such as one second or one minute, it can be determined that the broadcast video data includes a time display. This embodiment can more appropriately determine whether or not a time display is included, and can appropriately display the time.

[0076] This embodiment can suppress erroneous determination as a time display when, for example, characters or figures are written on a flipboard, etc. This embodiment can suppress erroneous determination as a time display when, for example, a character string indicating the time is written on a flipboard or the background of a broadcast studio, etc. This embodiment can suppress erroneous determination as a time display when, for example, broadcast video data includes a still image clock display that does not display the current time, etc.
