  Moreover, in the above-mentioned example, although the display control apparatus 11 is equipped in the television 1, it is not limited to this in this embodiment. For example, the display control device 11 can also be provided in a recorder, a player, an STB (Set Top Box), and the like.

[Display control unit 110]
The display control unit 110 adjusts the intensity of a specific wavelength in the display image to be displayed on the display unit 10 in the target time zone.

  More specifically, the display control unit 110 adjusts the intensity of the blue wavelength in the display image to be displayed on the display unit 10 so as to increase in the target time zone. That is, here, the target time zone means a time zone in which the intensity of the blue wavelength is high. The display control unit 110 transmits the adjusted video data to the display unit 10.

  Here, as shown in FIG. 1, the display control unit 110 includes a target time zone changing unit 1100 that changes a target time zone. The target time zone changing unit 1100 changes the target time zone, and the display control unit 110 changes the intensity of the blue wavelength in the display image in the target time zone.

  Thereby, even when the user travels to a travel destination with a time difference or comes back from the travel destination, the display control unit 110 can control the intensity of the blue wavelength in the display video in a suitable target time zone. It can be adjusted. As a result, the display control device 11 including the display control unit 110 preferably adjusts the user's biological rhythm even when the user travels to a destination with a time difference or comes back from the destination.

(Target time zone change unit 1100)
The target time zone changing unit 1100 changes the target time zone in a stepwise manner with reference to the adjustment target time difference and the pre-departure time difference adjustment days.

  Note that the information on the adjustment target time difference and the pre-departure time difference adjustment number of days can be obtained by the user inputting through the operation unit 12.

  Further, the above-mentioned pre-travel time adjustment days refers to, for example, a standard number of days for which jet lag can be reduced when the user travels to the destination.

  Hereinafter, an example in which the target time zone changing unit 1100 changes the target time zone with reference to the adjustment target time difference and the pre-travel time difference adjustment days before traveling from Japan to a destination such as Paris is shown in FIGS. 3 and 4. This will be described using

  First, the target time zone of the Japan standard and the target time zone of the Paris Standard will be described using (a) and (b) of FIG.

  (A) of FIG. 3 is a figure which shows the object time slot | zone of Japanese standard. As shown in (a) of FIG. 3, the display control unit 110 sets the target time zone of the Japan standard before the change to a time zone (from 6 o'clock to 18 o'clock) assuming that the television is viewed in the daytime. ing. That is, in (a) of FIG. 3, the intensity of the blue wavelength in the display image displayed on the display unit 10 is strong between 6 o'clock to 18 o'clock, and the intensity of the blue wavelength is weak at other times. It has become.

  (B) of FIG. 3 is a figure which shows the object time zone of Paris standard. As shown in (b) of FIG. 3, the target time zone changing unit 1100 changes the target time zone such that the target time zone is 6 o'clock to 18 o'clock based on Paris of the travel destination.

  However, since Paris is 8 hours behind Japan, the target time zone change unit 1100 is 6 o'clock to 18 o'clock when the value of the time on the horizontal axis in (a) of FIG. 3 is subtracted by 8 each. Change the target time zone to become That is, actually, when the target time zone changing unit 1100 converts the target time zone based on Paris into the target time period based on Japan, as shown in (d) of FIG. To change.

  Thus, in the display image, the display control unit 110 sets the target time zone so that the intensity of the blue wavelength increases in the same time zone (for example, 6 o'clock to 18 o'clock) as the time zone in which the intensity of natural light is strong. Set In addition, the target time zone changing unit 1100 changes the target time zone so that the target time zone is 6 o'clock to 18 o'clock on Paris basis.

  As described above, the display control device 11 provided with the display control unit 110 and the target time zone changing unit 1100 changes the intensity of the blue wavelength in advance so as to become the target time zone based on Paris before traveling by the user. Make it stronger. Thus, the display control apparatus 11 can adjust in advance the user's biological rhythm (circadian rhythm) in Paris as a destination before traveling by the user. As a result, even when the user travels to Paris, it is possible to reduce the jet lag in Paris of the destination.

  In the present embodiment, information on a target time zone based on Japan standards can be input to the display control unit 110 via the operation unit 12 at the time of initial setting of the television 1, for example. Thus, the display control unit 110 can calculate the target time zone at the destination by referring to the pre-travel time difference adjustment days and the adjustment target time difference input from the operation unit 12. As a result, the target time zone changing unit 1100 can change the target time zone to be the target time zone of the travel destination standard.

  Further, in the above-described example, the display control unit 110 changes the target time zone by the target time zone changing unit 1100 so that the intensity of the blue wavelength is increased from 6 o'clock to 18 o'clock on the basis of each country. However, the display control unit 110 can set the target time zone to an arbitrary time zone in accordance with the user's biological rhythm.

  Moreover, in the above-mentioned example, although the user has input the information on the time difference adjustment days before travel via the operation part 12, this embodiment is not limited to this. In the present embodiment, the display control unit 110 may automatically set the pre-travel time difference adjustment days according to the adjustment target time difference.

  For example, if the adjustment target time difference is 1 to 2 hours, the display control unit 110 may set the number of days before the departure of the travel adjustment day to 1 day. Further, the display control unit 110 sets the number of days before adjustment for travel to 2 days if the time difference for adjustment is 3 to 4 hours, and the time for adjustment for days before adjustment for 3 days if the time difference for adjustment is 5 to 6 hours It may be set to As described above, the display control unit 110 may automatically set the number of days before adjustment for adjustment so as to have a positive correlation with the adjustment target time difference.

(How to change the target time zone)
Next, referring to FIG. 4, an example of a method of changing the target time zone in which the target time zone changing unit 1100 changes the target time zone in steps with reference to the adjustment target time difference and the pre-departure time difference adjustment days is specifically described. Explain it.

  (A)-(d) of FIG. 4 is a figure explaining the object time slot | zone which the object time slot | zone change part 1100 changed on each day of the 1st-4th day. FIG. 4A is a diagram when the target time zone is shifted backward for one day (two hours). Similarly, (b) to (d) in FIG. 4 are diagrams when the target time zone is shifted backward by two days, three days, and four days, respectively, from the target time zone of the Japanese standard.

  As described above, the target time zone change unit 1100 shifts the target time zone back by 2 hours per day, and shifts the target time zone back by 8 hours which is the time difference between Japan and Paris in 4 days. There is. That is, the target time zone change unit 1100 is a two-hour time which is obtained by dividing an adjustment target time difference of 8 hours between Paris of the travel destination and Japan per day by the four days of the adjustment time difference before travel. The target time zone has been changed by the minute.

  As described above, the target time zone changing unit 1100 shifts the target time zone little by little for a fixed time every day, not once, and the display control unit 110 adjusts the intensity of a specific wavelength such as blue. Thus, the user's biological rhythm can be adjusted in advance so as to match the biological rhythm of the travel destination before going to a foreign travel destination with a time difference. As a result, even if the user goes to a destination with a time difference and looks at the display image, it is possible to reduce the user's jet lag.

  In the above example, the target time zone changing unit 1100 changes the target time zone by the time obtained by dividing the target time zone by the time difference adjustment days before the travel per day. However, it is not limited to this. In the present embodiment, the target time zone changing unit 1100 may change the target time zone in stages with reference to the adjustment target time difference and the time difference adjustment days before the departure.

  For example, if the adjustment target time difference is 8 hours and the time difference adjustment days before departure is 4 days, the target time zone change unit 1100 is 3 hours on the first day, 2 hours on the second day, and the third day The target time zone may be changed by 1 hour, 2 hours on the 4th day, and shifted by 8 hours in total on 4 days.

  Further, in the above-described example, the target time zone changing unit 1100 is stored in the display control unit 110, and the display control unit 110 also functions as the target time period changing unit 1100. However, the present embodiment is not limited to this. If each of the display control unit 110 and the target time zone changing unit 1100 can exhibit the functions described above, and if the display control device 11 is present, the target time period changing unit 1100 is provided outside the display control unit 110. It may be done.

(External Information Acquisition Unit 111)
The external information acquisition unit 111 acquires external information (for example, time, place, and weather) from a sensor (not shown) included in the television 1 and the Internet or the like, and transmits the external information (for example, time, place and weather) to the display control unit 110.

(Video signal acquisition unit 112)
The video signal acquisition unit 112 acquires a video signal of a broadcast such as a broadcast station and transmits the video signal to the display control unit 110.

[Operation unit 12]

As a result, the target time zone is gradually changed from the target time zone of Japan standard to the target time zone of destination standard.

  Step S103 (display control step): The display control unit 110 intensifies the intensity of the blue wavelength in the display image to be displayed on the display unit 10 in the target time zone changed in the target time zone changing step.

  Step S104: The display control unit 110 determines whether or not the pre-travel time adjustment day has been reached. When the pre-departure time difference adjustment days are reached (YES in step S104), the process proceeds to step S105. If the time difference adjustment days before travel has not been reached (NO in step S104), the process returns to step S102, and steps S102 to S104 are repeated.

  Step S105: If the display control unit 110 determines that the pre-departure time difference adjustment days have been reached, the display control unit 110 ends the display control process.

Further, the display control device 13 includes a display control unit 130 instead of the display control unit 110. Except for this point, the display control device 13 has the same configuration as the display control device 11.

[Display control device 13]
As shown in FIG. 6, the display control unit 130 in the display control device 13 includes a target time zone change unit 1300.

  The target time zone change unit 1300 changes the target time zone after returning from a travel destination such as Paris, instead of the function of the target time zone change unit 1100 or in addition to the function of the target time zone change unit 1100. Change in stages.

  Hereinafter, among the functions of the target time zone changing unit 1300, a function of changing the target time zone in stages after returning from a destination such as Paris will be described.

  Here, as shown in (b) of FIG. 3, the target time zone after the return from the travel destination before the change is from 6:00 to 18:00 in the target time zone of Paris standard (target time zone of Japanese Standard 14 o'clock to 2 o'clock). The target time zone of the Paris standard is calculated by the display control unit 130 based on the information of the Japanese standard target time zone stored in the display control unit 130 and the adjustment target time difference input from the operation unit 12. be able to. As shown in (a) of FIG. 3, the target time zone changing unit 1300 changes the target time zone in stages so as to be the target time zone based on the Japan standard.

Explain to.

  (A)-(d) of FIG. 7 is a figure explaining the object time slot | zone which the object time slot | zone change part 1300 changed on each day of the 1st-4th day. FIG. 7A is a diagram when the target time zone is shifted forward by one day (two hours) from the target time zone based on Paris after returning from Paris. Similarly, after returning from Paris, (b) to (d) in FIG. 7 respectively shift the target time zone forward by two days, three days, four days from the target time zone of Paris standard. When you

  As described above, the target time zone changing unit 1300 shifts the target time zone forward by 2 hours per day, and shifts the target time zone to 8 hours ahead, which is the time difference between Japan and Paris in 4 days. There is. In other words, the target time zone change unit 1300 is a two-hour time which is obtained by dividing the time difference between Paris of the travel destination and Japan by 8 hours on a day by 4 days of time difference adjustment days after returning to Japan. The target time zone has been changed by the minute.

  Here, the above-described time difference adjustment days after returning home refers to, for example, a standard number of days taken to eliminate jet lag when the user returns home from a travel destination.

  As described above, the target time zone changing unit 1300 shifts the target time zone little by little for a fixed time every day, not once. As a result, even when the user returns to Japan from a destination with a time difference, such as a foreign country, it is possible to adjust the intensity of a specific wavelength in the display image in accordance with the change in the user's biological rhythm. As a result, even if the user returns to Japan from a travel destination with a time difference and views the display image, it is possible to reduce the user's jet lag.

  In the above-described example, the user inputs information on the time difference adjustment days after returning from the home through the operation unit 12, but the present embodiment is not limited to this. In the present embodiment, the display control unit 110 may automatically set the time difference adjustment days after returning home according to the adjustment target time difference.

  For example, if the adjustment target time difference is 1 to 2 hours, the display control unit 130 may set the time difference adjustment days after returning home on the first day. Further, the display control unit 130 sets the time difference adjustment days after returning home on 2 days if the adjustment target time difference is 3 to 4 hours, and 3 days after return home if the adjustment target time difference is 5 to 6 hours It may be set to Thus, the display control unit 130 may automatically set the time difference adjustment days after returning so as to have a positive correlation with the adjustment target time difference.

[Display control method]
The flow of the display control method executed by the television 2 according to the present embodiment after returning from the travel destination will be described with reference to FIG. FIG. 8 is a flowchart showing the flow of the display control method.

  The television 2 according to the present embodiment performs display control processing by executing steps S201 to S205 described below.

  Steps S203 and S205 in FIG. 8 are the same as steps S103 and S105 in FIG. 5, and thus the description thereof is omitted here.

  Step S201: The display control unit 130 acquires, via the operation unit 12, information on travel destination, time difference to be adjusted, and time difference adjustment days after returning home.

  Step S202 (target time zone changing step): Next, the display control unit 130 causes the target time zone changing unit 1300 to adjust a target time zone for adjusting the intensity of a specific wavelength in the display image to be displayed on the display unit 10. Change with reference to target time difference and time difference adjustment days after returning home. As a result, the target time zone is gradually changed from the target time zone of the travel destination standard to the target time zone of the Japan standard.

  Step S204: The display control unit 130 determines whether or not the time difference adjustment days have been reached after returning home. If the time difference adjustment days after returning to home has been reached (YES in step S204), the process proceeds to step S205. If the time difference adjustment days have not been reached after returning to the home (NO in step S204), the process returns to step S202, and steps S202 to S204 are repeated.

Embodiment 3
In the first and second embodiments, the display control units 110 and 130 of the display control devices 11 and 13 acquire information on travel destinations and the number of days via the operation unit 12. However, as in the third embodiment, the display control unit 140 of the display control device 14 may obtain travel destination and information on the number of days via the input screen 150 on the display unit 15 instead of the operation unit 12.

[TV 3]
FIG. 9 is a block diagram showing the main configuration of the television 3 according to the present embodiment. As shown in FIG. 9, in the television 3 according to the present embodiment, the display unit 15 further includes an input screen 150 instead of the operation unit 12. In addition, in accordance with the input result of the input screen 150, the display control unit 140 increases the intensity of the blue wavelength in the display video in the target time zone. Except for this point, the television 3 has the same configuration as the television 1 according to the first embodiment and the television 2 according to the second embodiment.

[Display control device 14]
As shown in FIG. 9, the display control device 14 includes a display control unit 140, an external information acquisition unit 111, and a video signal acquisition unit 112.

  The display control unit 140 causes the display unit 15 to display the input screen 150, and calculates the adjustment target time difference with reference to the travel destination input through the input screen 150. Thereby, the input of the adjustment target time difference by the user can be omitted. Therefore, the display control device 14 can perform display control processing more efficiently.

[Display unit 15]
The display unit 15 displays an input screen 150 for receiving a user input regarding a travel destination. The input screen 150 will be described with reference to FIG. (A) of FIG. 10 shows an input screen 150 before input by the user, and (b) of FIG. 10 shows an input screen 150 after input of information on a destination by the user. The input screen 150 is a touch panel capable of inputting information with a finger or a pen of a user.

  As shown to (a) of FIG. 10, the display part 15 displays the input screen 150 with the "(circle)" button which selects whether it is going to travel or after returning home. The user can select by touching the “O” button after traveling or returning home.

  Hereinafter, the input method to the input screen 150 when the user selects the "O" button scheduled for travel will be specifically described.

(The input method to input screen 150)
First, the user selects the "O" button to be traveled, and then enters the destination in the blank. For example, the display unit 15 may display a screen such as a keyboard of a personal computer on the input screen 150 when the user touches a blank space of a destination. Thereby, the user can touch the keyboard on the input screen 150 to directly input the destination.

  In addition, the display unit 15 may display, for example, a list of countries around the world on the input screen 150 when the user touches a blank space of a destination. Thereby, the user can touch and select a destination from the list of countries around the world.

  Thus, when the user determines a destination, the display control unit 140 calculates an adjustment target time difference between the travel destination and the current location, and displays the adjustment target time difference on the input screen 150. For example, as shown in (b) of FIG. 10, when the destination is selected as Paris and the current location is Japan, the display control unit 140 calculates the time difference to be adjusted, -8 hours, and displays the input screen 150. Display.

  After the user selects a destination, the input screen 150 receives user input of the number of days (time difference adjustment number of days before travel) for reducing jet lag. As shown in (b) of FIG. 10, the user inputs the travel destination and the number of days for reducing jet lag, and then touches the “OK” button displayed on the upper right of the input screen 150.

  Thereby, the display control unit 140 refers to the travel destination, the adjustment target time difference, and the number of days for reducing jet lag (the number of days before the travel adjustment day) which are input to the input screen 150 by the target time zone change unit 1400. Change the target time zone gradually. In addition, the display control unit 140 increases the intensity of the blue wavelength according to the changed target time zone.

It may be set. That is, the display unit 15 may not display the number of days for reducing jet lag and the number of days to be used for jet lag cancellation on the input screen 150.

  In addition, the input screen 150 may further receive user input of a scheduled travel date in the travel scheduled column and a scheduled return date in the column after returning home. In this case, the display control unit 140 may increase the intensity of the blue wavelength while automatically and gradually changing the target time zone until the scheduled travel date or from the scheduled return date. . Thereby, the user can reserve a schedule on which the display control process is to be performed via the input screen 150. Therefore, the display control device 14 can perform display control processing more efficiently.

  If the user selects the "O" button to be traveled (the travel is scheduled in step S301), the process proceeds to step S302. If the user selects the “o” button after returning home (after returning home in step S301), the processing proceeds to step S303.

  Step S302: The display unit 15 causes the user to input on the input screen 150 the travel destination and the number of days for reducing jet lag (the number of days before the travel adjustment). The display control unit 140 acquires information on the travel destination and the time difference adjustment days before travel via the input screen 150. Further, the display control unit 140 refers to the travel destination input to the input screen 150 to calculate the adjustment target time difference.

  Step S303: The display unit 15 causes the user to input on the input screen 150 the travel destination and the number of days (time difference adjustment number of days after returning to home) to be used for jet lag cancellation. The display control unit 140 acquires information on travel destination and time difference adjustment days after returning from the home via the input screen 150. Further, the display control unit 140 refers to the travel destination input to the input screen 150 to calculate the adjustment target time difference.
