  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a configuration of a projection display device (image display device) according to an embodiment of the present invention.

  The image display apparatus according to the present embodiment includes a control unit that selectively executes a first operation associated with the date and time and a second operation associated with the date and time, an acquisition unit that acquires information about the date and time, It has. Here, the control means is the reference numeral 102 shown in FIG. 1, but the drive program management unit 110, various drive programs 111, 112, 113, the power supply control unit 103, the light source 104, the panel (image display element) 106, and the like. It may also serve as a controller for controlling the above. Here, the control unit can selectively execute one of the first operation and the second operation based on the date and time acquired by the acquisition unit.

  Here, the first operation is an operation that is repeated every day, every week, every month, or every year, that is, an operation that is repeated at a constant cycle. On the other hand, the second operation is an aperiodic operation, an operation without repetition, that is, an operation performed on a specific date or day, or an operation that is repeated within a shorter period than the first operation (repetition cycle). May be the same as the first operation). Alternatively, the date and time associated with the first operation is not the year and month but the date and time related to at least a part of the day of the week and the time on the at least part of the day of the week. The date and time associated with the second operation may be a date and time related to at least a part of the month and day and a time in the at least part of the month and day. Further, the date and time associated with the first operation is a time, not a year, month, day, and the first operation is an operation that is repeated every day. The date and time associated with the second operation may be a date and time related to at least a part of the date and time in the at least a part of the date.

  The first operation and the second operation described above are preferably operations that repeat from the start to the end of the image display device one or more times. That is, it is desirable that the start of each operation is an apparatus start sequence and the end is an apparatus end sequence. However, in some cases (when it is preferable for the end to be performed by a person), the end sequence may not be included. What kind of operation each operation includes is a matter set by the user. That is, the first and second operations are operations based on the drive schedule or the drive schedule (performs an operation at a certain date and time) itself. In this embodiment, the first operation (first drive program, operation based on the first drive schedule) and the second operation (second drive program, operation based on the second drive schedule) are selected. Provided is an image display device that can be performed automatically. Here, the first operation is an operation performed under a daily normal schedule, and this is an operation when the same thing is repeated every day, every week, every month, every year ( Operation schedule, drive schedule). In addition, the second operation is an operation that is executed only when the date and time obtained by the date and time information acquisition unit matches (matches) the specific date and time associated with the second operation, and is an event different from daily events. This is the operation that is executed when this occurs.

  The date and time associated with the first operation and the date and time associated with the second operation may partially overlap each other or may be different from each other. However, when the date and time associated with the second operation is set (input) by the setting means, setting may be prohibited for the date and time already set in the other second operation.

  When the date and time acquired by the acquisition unit is the date and time associated with the second operation, the control unit according to the present embodiment executes the second operation and does not correspond to the date and time associated with the second operation. If the date / time associated with the first operation falls within the range, the first operation is executed. Further, when there are a plurality of second operations (second drive program, second schedule) (when there is a third operation), according to the priority order associated with the second operation. Determine the action to be performed.

  A projection display device (image display device, projector) according to a first embodiment of the present invention will be described below with reference to FIG.

  Reference numeral 101 denotes a projection display device (image display device) according to the first embodiment of the present invention. Reference numeral 102 denotes a control unit that controls various functional blocks to be described later. Reference numeral 103 denotes a power supply control unit that controls power supply to the light source 104. Reference numeral 104 denotes a light source which emits light upon receiving power supply from a power supply control unit. A color separation optical system 105 separates the light emitted from the light source for each predetermined color component. Generally, the three primary colors R, G, and B are separated. A panel (image display element) 106 modulates light for each color component output from the color separation optical system 105 so as to form a desired image (controls the polarization direction or the light emission direction). To do). Note that there are a plurality of panels for performing separate modulation for each color component. A color synthesis optical system 107 synthesizes light for each color component modulated by the panel. A part (or all) of the color combining optical system 107 and the above-described color separation optical system 105 may be a common optical system. The light synthesized by the color synthesizing optical system is output to the outside of the projection display device 101 via the projection optical system 108 and projects (images) a projection image on an external screen (not shown). Reference numeral 109 denotes a date and time acquisition unit that acquires date and time information (current date and time information). Examples of the configuration of the date / time information include information (data) including numerical values representing year, month, day, hour, minute, and second, information composed of only a part (for example, only hour and minute), and the like. Reference numeral 110 denotes a drive program management unit, which sets drive program / period information and selects a drive program to be executed.

  Reference numeral 111 denotes a drive program that is not associated with period information. Reference numerals 112 and 113 denote driving programs associated with the period information 114 and 115, respectively. As the period information 114 and 115 in the first embodiment, a start date and an end date are set, respectively.

  Here, the flow of drive program selection will be described with a specific example.

  The period information 114 is set with a start date of April 1, 2020 and an end date of April 30, 2020, and the period information 115 is set with a start date of July 20, 2020 and an end date of August 31, 2020. It shall be.

  The control unit 102 periodically acquires date information from the date acquisition unit. When the acquired date and time information crosses the date, the drive program corresponding to the acquired date is acquired via the drive program management unit 110. The drive program management unit 110 determines whether or not the date is included in the period information 114 and 115, and if it is included, acquires the period drive program linked to the period information. When none of the period information includes the date, the drive program 111 (normal drive program) is acquired.

  For example, when the date in the acquired date and time information is August 1, 2020, the drive program management unit acquires the period drive program 113 because the date is included in the period information 115. If the date in the acquired date information is June 1, 2020, the drive program management unit acquires the normal drive program 111 because the date is not included in any of the period information 114 and 115.

  The control unit 102 controls the projection display apparatus 101 according to the drive program acquired via the drive program management unit 110. Furthermore, the date and time information is continuously acquired from the date and time acquisition unit, and the drive program acquisition process is performed again when the date is crossed.

  Here, an example of the configuration of the drive program will be described with reference to FIG.

  The drive program is composed of a combination of “time” and operation information (expressed as “command” in FIG. 2) executed at the time.

  In the example shown in FIG. 2, the projection display device is turned on by a POWER = ON command at 8:00, and simultaneously the input signal selection of the projection display device is set to 1 by an INPUT = 1 command. Here, the input signal selection 1 is a numerical value for convenience. Actually, one of the input signal terminals [HDMI (registered trademark), VGA, etc.] provided in the projection display device is selected. Become. At 10:00, the input signal selection of the projection display device is set to 2 by the INPUT = 2 command, and at 12:00, the projection display device is turned off by the POWER = OFF command. At 13:00, the projection display device is turned on by the POWER = OFF command, and at the same time, the input signal selection of the projection display device is 3 by the INPUT = 3 command. At 17:00, the POWER = OFF command turns off the projection display device.

  With respect to the drive program, one program may be executed every day, or a separate drive program may be executed every day of the week. When a separate drive program is executed for each day of the week with respect to the period drive program, the drive program corresponding to the day of the week is executed from the start date to the end date of the period information.

  Here, it has been described that the normal drive program 111 is not associated with the period information, but of course, it may be associated with the period information.

  Hereinafter, the operation of the projection display apparatus according to the second embodiment of the present invention will be described with reference to FIG.

  In the present embodiment, a configuration will be described in which when there are two or more period drive programs, the setting for overlapping the period information among a plurality of period drive programs is suppressed.

  In the projection type display apparatus according to the present invention, when setting the period information (date information) associated with the period drive program, for example, it is performed by an operation from an operation device such as a remote controller. The period information setting dialog is displayed on the on-screen menu using the remote controller, and the date / time information can be set by operating the items on the on-screen menu using the remote controller.

  301 is an example of a setting screen for period information associated with the period driving program. 302 represents a start date input unit, and 303 represents an end date input unit.

  The start date and end date are entered by placing the cursor 304 on the item and increasing / decreasing the value with the up / down keys. Alternatively, a value is directly input with a numeric key while the cursor 304 is in contact.

  When one of the values of the start date and the end date is changed, the control unit passes the start date / end date information to the drive program management unit, and the drive program management unit sets the drive program other than the drive program being edited. It is determined whether or not the period information overlaps.

  When the drive program management unit determines that it overlaps with the period information associated with the drive program other than the drive program being edited (overlaps with the date / time information), the control unit displays that on the screen menu 301. indicate. Specifically, a message 305 indicating that the period information (date and time information) is duplicated is displayed on the on-screen menu 301, and the setting of the period information is not executed (setting of the date and time information when the date and time are duplicated is prohibited). .

  With such a configuration, even when there are a plurality of period driving programs, the period information does not overlap with each other, so that the driving program management unit can uniquely specify the execution target program for a predetermined date.

  Hereinafter, the operation of the projection display apparatus according to the third embodiment of the present invention will be described with reference to FIG.

  Reference numerals 114 and 115 denote period information related to the period driving programs 112 and 113, respectively. In this embodiment, it is possible to set overlapping periods. For example, the start date of the period information 114 is set to May 1, 2020, the end date is set to June 30, 2020, the start date of the period information 115 is set to June 1, 2020, and the end date is set to July 2020. It is possible to set 31 days. When such a setting is made, the periods overlap from June 1, 2020 to June 30, 2020. In the overlapped period, the drive program management unit 110 cannot determine which of the period drive programs 112 and 113 is the execution target only by the period information.

  Therefore, in this embodiment, priority information that does not overlap each other is associated with each period driving program.

  For example, a format in which the priority order information is held as a numerical value can be considered. It is assumed that “1” is set in the priority information 401 and “2” is set in the priority information 402, and the higher the numerical value, the higher the priority. In this case, the period driving program 113 is executed in the period in which the period information 114 and 115 overlap each other.

  The operation of the projection display device according to the fourth embodiment of the present invention will be described below with reference to FIG.

  In this embodiment, the period driving programs 112 and 113 are associated with event identification information 501 and 502, respectively. The event identification information is, for example, a character string representing an event, and “SUMMER_VACATION”, “SCHOOL_FESTIVAL”, etc. are set. These character strings can be in a format that can be arbitrarily set by the user. However, it is also possible to obtain the event identification information already set in the event information server 504 from the event information server 504 via the communication unit 503, and select the format from which the user selects.

  FIG. 6 shows an example of an on-screen menu 601 when selecting event identification information associated with a period driving program. Reference numeral 602 denotes an event identification information selection unit. The control unit 102 selects an arbitrary event identification information character string by a user operation from a plurality of event identification information character strings acquired from the event information server 504 via the communication unit 503.

  When the event identification information character string is changed by a user operation, start date and end date information related to the changed event identification information character string is acquired from the event information server, and the start date display unit 603, end date Displayed on the display unit 604.

  Here, the flow of drive program selection will be described with a specific example.

  It is assumed that “SUMMER_VACATION” is set in the event identification information 501 and “SCHOOL_FESTIVAL” is set in the event information 502.

  The control unit 102 periodically acquires date information from the date acquisition unit. When the acquired date and time information crosses the date, the drive program corresponding to the acquired date is acquired via the drive program management unit 110. The drive program management unit 110 requests the control unit 102 for period information corresponding to the event identification information “SUMMER_VACATION” and “SCHOOL_FESTIVAL”.

  The control unit 102 notifies the drive program management unit of period information corresponding to the event identification information “SUMMER_VACATION” and “SCHOOL_FESTIVAL” from the event information server 504 via the communication unit 503.

  The drive program management unit 110 determines whether or not the date acquired from the date acquisition unit 109 is included in any of the period information notified corresponding to the event identification information 501 and 502, and if included, the corresponding period Get the driving program. When none of the period information includes the date, the drive program 111 (normal drive program) is acquired.

  The control unit 102 controls the projection display apparatus 101 according to the drive program acquired via the drive program management unit 110. Furthermore, the date and time information is continuously acquired from the date and time acquisition unit, and the drive program acquisition process is performed again when the date is crossed.

  In addition, although the example of the implementation | achievement by a character string was given as event identification information, another realization method is also considered and it is also possible to handle ID number which identifies an event as event identification information.

  Hereinafter, the operation of the projection display apparatus according to the fifth embodiment of the present invention will be described with reference to FIG. The projection display device according to the fifth embodiment of the present invention includes a calendar display means.

  Reference numeral 701 denotes a configuration example of an on-screen menu serving as a calendar display unit. In the calendar display on-screen menu 701, the horizontal axis shows the months arranged in time series from left to right. The normal drive program and the valid period of each period drive program (the period selected as a drive target by the drive program acquisition unit) are displayed in a band shape.

  For example, a period driving program with a start date of June 10, 2020 and an end date of September 10, 2020, and a period driving program with a start date of March 1, 2020 and an end date of April 30, 2020 Is set. In the calendar display on-screen menu 701, the display method (band thickness, color, etc.) of the band is changed and displayed so that the effective period of each period driving program can be identified. In this way, by displaying the driving program (operation) executed by the program execution means (control means) on the calendar, the user-friendliness is improved.

  Further, since the normal drive program is not executed during the effective period of the period drive program, the normal drive program band is displayed by a display method corresponding to “invalid”.

  In this way, the user can identify which program is acquired as an execution target by the drive program acquisition unit in a predetermined period.

  With reference to FIGS. 8 and 9, the operation of the projection display apparatus according to the fifth embodiment of the present invention will be described.

  FIG. 8 shows an example of a driving program in this embodiment. A power-on command is executed at 12:00, and a power-off command is executed at 17:00. Calibration is scheduled to be executed at 18:00. Here, calibration refers to, for example, determining the light emission state of the light source with a luminance sensor, and determining that the desired luminance is not obtained, increasing the power supplied to the power supply control unit 103 to obtain the desired luminance. It is a process to obtain. Even if the power supplied from the power control unit to the light source is the same, the luminance output from the light source changes if the temperature state of the light source is different.

  Therefore, in order to execute calibration, it is necessary to perform the calibration while the temperature change of the light source is stable, and it is desirable that a predetermined time elapses with the light source turned on. The passage of a predetermined time with the light source turned on is called aging.

  Considering the aging time, there is no problem if the user sets up a program that executes the calibration command after turning on the light source for a predetermined time or longer, but otherwise the calibration cannot be executed correctly.

  For example, when the drive program as shown in FIG. 8 is executed as it is, the calibration is not possible because the power-off command registered at 17:00 is already in the standby state when the calibration is executed. .

  Therefore, in the projection display apparatus according to the present embodiment, prior to execution of the power-off command, when a command scheduled thereafter requires calibration, the command is executed before the power-off command.

  In another condition, a calibration command may be registered immediately after the power-on command. For example, a power-on command is registered at 12:00 and a calibration command is registered at 12:05. If the aging time required for calibration is 30 minutes, the necessary aging time cannot be secured by executing calibration at 12:05 (time information included in the command).

  Therefore, in the projection display apparatus according to the present embodiment, it is determined whether or not the time from the start of projection exceeds the aging time (the aging time acquired by the aging time acquisition unit) prior to the execution of calibration. As a result of the determination, if the predetermined aging time is not exceeded, the calibration execution time is delayed by at least a difference value between the aging time and the time (elapsed time) from the start of projection.

  By doing in this way, a required aging time can be ensured and a calibration process can be performed appropriately.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.

  The image display apparatus of the present invention can be applied to a projector (a display device may be a liquid crystal, a mirror device, or any other device) and a system using a projector.
