FIG. 3 is a flow chart showing the timing at which the time measuring section 22 starts measuring time.
The time measuring unit 22 starts the process when the presentation start mode is selected by the presenter.
When the control signal is input from the operation unit 5 by operating the presenter, the time measuring unit 22 determines whether the control signal is a projection power ON signal for turning on the projection power of the display unit 11 of the projector 1 (S101). ; YES, S1
02). When the control signal is the projection power ON signal, the total elapsed time measuring unit 2 starts so as to start measuring the total elapsed time.
2a is instructed to proceed to step S101 (S103).

In response to this instruction, the total elapsed time measuring unit 2
2a resets the clock counter and starts clocking,
The measured total elapsed time is output to the display unit 21, and is displayed as “whole ... 16:28” as shown in FIG. 1, for example. Next, in step S102, if the input control signal is not the projection power ON signal, it is determined whether the control signal is an image switching signal (S104). When the control signal is the image switching signal, the image elapsed time measuring unit 22b is instructed to start measuring the image elapsed time, and the process proceeds to step S101 (S105).

In response to this instruction, the image elapsed time measuring unit 22
In b, the clock counter is reset to start clocking, and the measured image elapsed time is output to the display unit 21, and is displayed as "image ... 01:30", for example, as shown in FIG. On the other hand, when the input control signal is not the image switching signal in step S104, it is determined whether the control signal is the projection power OFF signal (S106). If the control signal is not the projection power supply OFF signal, the process proceeds to step S101, and if it is the projection power supply OFF signal,
The total elapsed time measuring unit 22a is instructed to end the time counting, and the image elapsed time measuring unit 22b is instructed to end the time counting, and the process proceeds to step S101.

As described above, the overall elapsed time, which is the elapsed time from the start of the presentation, and the image elapsed time, which is the elapsed time after each image is displayed, are displayed. If you look at the display unit 21 of the portable terminal 2 carried inside, the entire elapsed time can be grasped, and since the image elapsed time is also displayed every time the image is switched, the progress status of the presentation can be grasped in detail for each image. .

Furthermore, since the total elapsed time and the image elapsed time are displayed on the display unit 21 of the portable terminal 2, it is not necessary to display the image on the screen 19, and the listener can concentrate on the presentation. Since the total elapsed time and the image elapsed time are automatically measured based on the operation content of the mobile terminal 2 of the presenter, the presenter does not need to perform an operation for time measurement and concentrate on the presentation. You can

In step S255 of FIG. 6, when the image elapsed time exceeds the scheduled time, that is, when the presentation is behind the schedule, "remaining ... -0:
For example, "-" is displayed before the remaining time, such as "25". Therefore, even if the presentation is behind schedule, the presenter can grasp the situation at a glance.

As described above, since the remaining time of each image with respect to the scheduled time is displayed on the display unit 21 of the portable terminal 2, the presenter can know the progress status of the presentation for each image. Therefore, if the presentation of each image is completed within the scheduled time, the entire presentation can be surely completed within the presentation time. 3. Others In the above-described second embodiment, when the presenter inputs the scheduled time of each image, the number of scheduled times is input incorrectly, and the number of images used for the presentation matches the input scheduled time. There are times when you don't.

That is, there is a case where the planned time for 10 images should be input, but the planned time for 9 images is mistakenly input. In this way, when the presentation is started with the input error of the scheduled time, there is no scheduled time for one sheet, and the progress status of the presentation with respect to the entire presentation time cannot be known, and the presenter may be confused. In order to eliminate such an input error, the following example can be considered.

A) The projector 1 includes the file storage unit 1
The total number of images (hereinafter, referred to as “total number of images”) is acquired from the presentation file stored in No. 4, and the total number of images is transmitted to the mobile terminal 2. On the other hand, the mobile terminal 2
When comparing the total number of images with the expected number of hours input from the presenter, the display unit 21 may display a message such as “there is an input error”.

Therefore, in addition to the function of storing and managing the presentation file received from the PC 4, the file storage unit 14 of the projector 1 has a function of acquiring the total number of images from the presentation file and transmitting it to the portable terminal 2 via the communication unit 16. Have. The total number of images corresponds to the number of pages in the presentation file and can be obtained from the application software installed in the projector 1.

On the other hand, in the portable terminal 2, the total number of images transmitted from the projector 1 is received by the communication section 26 and output to the scheduled time storage section 23. The scheduled time storage unit 23 determines whether the scheduled number of images input by the presenter and the total number of images received from the projector 1 match, and if they do not match, the display of the mobile terminal 2 is displayed. The unit 21 has a function of instructing to display the content indicating the input error of the scheduled time.

Specifically, in FIG. 6, step S2
After the processing of YES in 56, it is determined whether or not the variable N matches the total number of images. If they match, the processing ends, and if they do not match, the display unit 21 indicates that there is a mismatch. A signal may be output, the process proceeds to step S252, and the variable N may be input again from 1. It should be noted that the display unit 21 displays "there is an error in inputting the scheduled time" when a signal indicating the disagreement is input.

B) In the above a), the portable terminal 2 receives the total number of images from the projector 1, but the presenter may input the total number of images when inputting each scheduled time. By doing so, it is not necessary for the file storage unit 14 of the projector 1 to acquire the total number of images from the presentation file, and the structure of the file storage unit 14 of the projector 1 can be simplified as compared with the above example a).

C) In the above-described second embodiment, the remaining time after the image is displayed with respect to the scheduled time of each image is displayed on the display unit 21.
Is displayed. Therefore, even if the presenter can grasp the remaining time for each image, it is difficult to understand the progress status with respect to the entire presentation time. For example, there are 10 images to be used, only one of the 4th displayed images greatly exceeds the scheduled time, and the remaining 9 images will finish the presentation within the scheduled time even if the presentation is completed within the scheduled time. Sometimes you can't.

In order to eliminate such a thing, for example,
When the image presentation time exceeds the scheduled time, the excess time may be subtracted from the scheduled time of the remaining images, and the presentation as a whole may be completed within the time. As a matter of course, after the image that exceeds the scheduled time, the display unit 21 displays the remaining time after subtracting the excess time.

D) In the second embodiment, the scheduled time is input using the operation keys, but other input methods may be used. For example, the display unit 21 may be configured as a touch panel, and the touch panel may be used for inputting, or the input may be performed by using a sillus pen. e) In the second embodiment, the time allotted to the presentation of each image is input as the scheduled time and the remaining time after switching the images is calculated. However, the presentation presentation time is input as the scheduled time. However, the remaining time calculation unit may calculate the remaining time with respect to the presentation time.

(Third Embodiment) Next, the third embodiment of the present invention will be described.
The embodiment will be described. In the second embodiment, the presenter needs to enter the scheduled time for each image before the presentation. Therefore, it is not so problematic when practicing presentations, but if there are multiple presenters, it is not possible to proceed smoothly with the presentation. In the present embodiment, a case will be described in which the presenter does not need to input the scheduled time before the presentation.

1. Overall Configuration of Presentation System In the present embodiment, the scheduled time corresponding to each image is set in PC4.
Created in, send this scheduled time to projector 1,
The scheduled time received by the projector 1 is transmitted to the mobile terminal 2. Here, the scheduled time created by the PC 4 is stored in the header portion added to the data when the presentation file is transmitted to the projector 1, and the scheduled time created by the PC 4 is stored in the projector 1.
The case of sending to will be described.

1. Configurations of PC and Projector FIG. 7 is a functional block diagram showing configurations of the PC 4, the projector 1, and the mobile terminal 2 according to the third embodiment. The same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted. As shown in the figure, the PC 4 includes a file creation unit 41 as in the above-described embodiments, and a scheduled time setting unit 42 for setting a scheduled time,
The presentation unit includes a transmitting unit 43 that attaches the scheduled time to the presentation file and transmits the presentation file to the projector 1. A communication protocol capable of exchanging files is used between the PC 4 and the projector 1.

The file creating section 41 uses the first and second files described above.
In the embodiment, the data of a plurality of images used for the presentation is stored in one presentation file, but in the present embodiment, the data of one image used for the presentation is stored in one presentation file. ing. That is, the number of presentation files is the same as the number of images used for the presentation. This presentation file has, for example, a data format of JPEG.

In this case, the file creating section 41
The file storage unit 14 or the file decompression unit 13 of the projector 1 has a decompression function of decompressing the image data of the received presentation file, while having a compression function of compressing the created image data. The scheduled time setting unit 42 is for setting a scheduled time assigned to the description of the image used in the presentation, and is input from an input device such as a keyboard and a mouse. The transmission unit 43 transmits data (hereinafter, “transmission data”) to be transmitted when transmitting the presentation files to the projector 1 in the order of images used for the presentation.
Say. ) The scheduled time is stored in the header part at the beginning of) and transmitted. The presentation file and the order of transmission to the projector 1 are associated with each other based on the numerical value included in the presentation file name.

FIG. 8 is a diagram showing a data structure when transmitting the data of the presentation file. As shown in the figure, a data main body composed of data to be transmitted,
It consists of a header part attached to the beginning of this data body part. The header part is divided into multiple fields,
An image number indicating the display order of images in the presentation is stored in the second field, a scheduled time is stored in the second field, and the total number of images used in the presentation is stored in the third field. The image number is set from the number included in the presentation name.

The projector 1 has substantially the same configuration as the first and second embodiments described above, except that it has a function of transmitting the scheduled time acquired from the transmission data from the communication unit 216 to the portable terminal 2. It is a point to have. It should be noted that the file storage unit 14 has the same configuration as the first and second embodiments.
It naturally has a function of storing the presentation file received from the PC 4 in the file storage unit 14.

The mobile terminal 2 has substantially the same structure as that of the second embodiment. The present embodiment is different from the first and second embodiments in that the presenter inputs the scheduled time from the operation unit 5 in the second embodiment, but in the present embodiment, the scheduled time is acquired from the projector 1. That is the point. Therefore, when the scheduled time is input from the projector 1 via the communication unit 226, the scheduled time storage unit 223 stores the scheduled time in the scheduled time table in the order of input.

2. Description of Operation of Projector The operation of the file storage unit 14 of the projector 1 in the presentation system having the above configuration will be described. Figure 9
3 is a flowchart showing the processing contents of the file storage unit 14 of the projector 1. First, the file storage unit 14
Sends the transmission data of the presentation file to PC4
When it is received, the processing is started, and the variable I indicating the image number is set to 1 (S301). Among the transmission data, the transmission data whose image number in the header part is “I” is acquired (S3
02).

Then, it is determined whether or not the variable I is "1", and if it is "1", the total number of images (total number of images) K is acquired from the header part, and then the scheduled time is acquired from the header part. And outputs to the communication unit 216 (S303; YES, S3).
04, S305). If the variable I is not "1", the communication unit 2 acquires the scheduled time from the header of the transmission data.
It outputs to 16 (S303; NO, S305).

Next, it is judged whether or not the variable I and the total number K of images match, and when they do not match, that is, when the scheduled time that has not been acquired remains, the variable I is set to 1
Is added and the process proceeds to step S302 (S306; NO,
S307). If they match, that is, if the scheduled times have been acquired for all the images, the process ends (S306; YES). The scheduled time output from the file storage unit 14 is obtained from the communication unit 216 from the mobile terminal 2
Is transmitted to the communication unit 226.

3. Others a) In the above embodiment, when the PC 4 transmits the presentation file to the projector 1, the PC 4 stores the scheduled time in the header portion of the transmission data.
For example, the PC 4 may create a scheduled time file that stores the scheduled time separately from the presentation file, and may transmit the presentation file and the scheduled time file to the projector 1 separately. Then, the projector 1 may transmit the received scheduled time file to the mobile terminal 2 side.

Further, the PC 4 and the mobile terminal 2 are communicably connected to each other, specifically, by a wireless LAN so that the PC 4 directly transmits the scheduled time file created separately from the presentation file to the mobile terminal 2. May be. b) In the above a), the file for the scheduled time for storing the scheduled time is created separately from the presentation file. However, even if the scheduled time is stored in a table and this table is attached to the presentation file, It is good, and the scheduled time may be stored in the data of the presentation file.

C) Third embodiment, above a) and b)
In the example, one image corresponds to one presentation file, but the present invention can be applied to the presentation files in the first and second embodiments. For example, in order to carry out the same as in the third embodiment, the scheduled time may be stored in the header part of the first transmission data.

(Fourth Embodiment) Next, the fourth embodiment of the present invention will be described.
The embodiment will be described. In the first to third embodiments, the total elapsed time and the time relating to each image elapsed time (image elapsed time or remaining time) are displayed on the display unit 21 of the mobile terminal 2, but only the entire elapsed time is displayed. May be displayed.

In such a case, the operation section 5 of the portable terminal 2 has a measurement start key for starting the presentation, that is, for measuring the total elapsed time, and ending the presentation, that is, measuring the total elapsed time. A measurement end key for performing the measurement is provided. Then, the presenter operates the measurement start key at the start of the presentation and operates the measurement end key at the end of the presentation.

However, when the presenter inadvertently forgets to operate the measurement start key when starting the presentation, the entire elapsed time is not measured and the presenter cannot know the elapsed time at all. . Therefore, in the present embodiment, a case will be described in which even if the presenter forgets the operation of the measurement start key and starts the presentation as described above, the presenter is notified that the operation of the measurement start key has been forgotten. .

1. Configuration of Projector FIG. 10 is a functional block diagram showing the configuration of the projector 1 according to the fourth embodiment. Mobile terminal 2 and PC
Since the configuration of No. 4 is the same as that described in the first embodiment, illustration and detailed description thereof are omitted here. The operation unit 5 of the mobile terminal 2 has a measurement start key for instructing to start measurement of the entire elapsed time, as described above.
A measurement end key for instructing the end of the measurement is included.

The projector 1 is provided with a regulation section 17 which regulates the display of an image when the measurement start signal indicating the start of the presentation is not received. Specifically, the regulation unit 17 determines whether or not the measurement start signal has already been received from the mobile terminal 2 when the image feed signal instructing the display of the first image is received from the mobile terminal 2, When it is determined that the measurement start signal is received, this image feed signal is output to the image control unit 15.

On the contrary, when it is determined that the measurement start signal has not been received, the output of the image feed signal to the image control unit 15 is restricted. The communication unit 16 of the projector 1 outputs all the control signals received from the mobile terminal 2 to the restriction unit 17. 2. Description of Operation of Projector The operation of the projector 1 having the above configuration will be described below. FIG. 11 is a flowchart showing the processing contents of the determination unit of the projector 1.

The restriction unit 17 starts the process when the presentation software of the projector 1 is activated. First, the input flag indicating whether or not the measurement start signal is input is set to "0" (S401). And
When a signal is input to the restriction unit 17 from the communication unit 16 (hereinafter, this signal is referred to as "input signal"), it is determined whether the input signal is a measurement start signal (S402; YE).
S, S403). If the input signal is the measurement start signal,
The input flag is set to "1", this measurement start signal is output to the image control unit 15, and the process proceeds to step S402 (S403;
YES, S404, S405).

If the input signal is not the measurement start signal in step S403, it is determined whether the input signal is the image feed signal (S403; NO, S406). If the input signal is the image feed signal, it is determined whether or not the input flag is "1". If the input flag is "1", the input signal is output to the image control unit 15, and the process proceeds to step S402 ( S406; YES, S409; YES, S405).
Conversely, when the input flag is "0", that is, when the measurement start signal is not received, the process proceeds to S402 (S409; N).
O).

On the other hand, in step S406, when the input signal is not the image feed signal, it is determined whether or not the input signal is the measurement end signal, and when it is not the measurement end signal, the input signal is output to the image control unit 15. The process proceeds to step S402 (S406; NO, S407; NO, S405). If the signal is a measurement end signal, the input flag is set to "0", then the measurement end signal is output to the image controller 15 and the process proceeds to step S402 (S407; YES, S408, S4).
05).

As described above, when the projector 1 receives the first (first) image feed signal, it determines whether or not the measurement start signal has already been received, and does not receive the measurement start signal. At this time, the image feed signal is not output to the image control unit 15. Therefore, even if the presenter forgets to operate the measurement start key or mistakenly operates another key, the presenter does not display the first image, and the presenter does not make a mistake in inputting the measurement start key. notice. It should be noted that if the operation of the measurement start key is forgotten, the start of measurement of the entire elapsed time is slightly delayed, but the time is short and does not affect the presentation.

3. Others a) In the above-described fourth embodiment, the restriction unit 17 is provided in the projector 1 to restrict the display of images in the projector 1. However, for example, the restriction unit 17 is provided in the mobile terminal 2. Is also good. Specifically, in the flowchart of FIG. 11, step S405 can be implemented by transmitting the input signal from the communication unit 26 to the projector 1 instead of outputting the input signal to the image control unit 15.
Even in this case, the same effect as that of the above-described embodiment can be obtained.

B) In the above-described fourth embodiment, when the presenter forgets to operate the measurement start key at the start of the presentation, the display of the first image is restricted and the presenter sets the measurement start key. Although the operation forgetting is notified, the presenter may be notified by another method. As such an example, when the presenter forgets to operate the start key and operates the projector 1 to display the first image, a warning sound is generated. To configure in this way, in the flowchart of FIG. 11, step S40
If the input flag is "0" in 9 (NO), a warning sound is generated.

C) In the example of a) above, the warning sound as in b) above may be issued. Further, the mobile terminal 2 may be vibrated instead of the warning sound, and the display unit 2
1 may display "Measurement start key operation error".
In particular, when the operation error is displayed on the display unit 21 when the mobile terminal 2 is vibrated, a warning sound is generated or the measurement start key is operated by the listener as compared with the case where the first image is not displayed. Mistakes are hard to find.

(Fifth Embodiment) Next, the fifth embodiment of the present invention will be described.
The embodiment will be described. In the first to fourth embodiments, the presenter needs to visually check the display unit 21 of the mobile terminal 2 in order to grasp the time information, and it is difficult to concentrate on the presentation itself. On the contrary, because the user concentrated too much on the presentation, the display unit 21 of the mobile terminal 2
If you forget to check the time information of and see the time information after a while, it may become irretrievable.

In this embodiment, a case will be described in which the presenter can grasp the progress of the presentation to some extent without visually checking the display unit 21 of the portable terminal 2. 1. Configuration of Mobile Terminal In the present embodiment, a notification unit is provided to notify the presenter that the set time has come when the measured time reaches a preset time.

FIG. 12 is a functional block diagram showing the configuration of the mobile terminal 2 in the fifth embodiment. Since the configurations of the projector 1 and the PC 4 are the same as those described in the first embodiment, illustration and detailed description thereof will be omitted here. The mobile terminal 2 includes the operation unit 5, the communication unit 26, the time measuring unit 522, and the display unit 21 as in the first embodiment, and also the setting for storing the set time input from the input key of the operation unit 5. The time storage unit 29 and the set time determination unit 28 that determines whether or not the total elapsed time measured by the total elapsed time measurement unit 522a matches the set time.
And a vibrating unit 27 that vibrates the mobile terminal 2 itself when the set time determination unit 28 determines that the set time and the total elapsed time match. The notification unit is composed of the vibration unit 27.

The input key for inputting the set time and the input method are the same as those in the second embodiment. The set time storage unit 29 includes a set time table, and stores the set times in the input time order in the set time table. In this embodiment, the set time number is input, and the set time number is stored in the set time table together with the set time. The input order of the set time is the earliest order based on the start of the presentation.

2. Description of Operation of Mobile Terminal The operation of the presentation system having the above configuration will be described below. The presenter sets a time to be notified during the presentation and inputs this set time from the input key. The input set time is stored in the set time table of the set time storage unit 29. The set time input here is, for example, if the presentation time of the presentation is 10 minutes, 5 minutes at the midpoint and 9 minutes before the end.
Minutes and 10 minutes at the end. Also, the number of set times is 3, and these set times are input in the order of “3”, “5”, and “10”.

FIG. 13 shows the set time determination unit 2 of the mobile terminal 2.
8 is a flowchart showing the processing contents of No. 8. As shown in FIG. 13, the set time determination unit 28 starts the process when the presentation start mode is selected by the presenter. When the input of the total elapsed time from the total elapsed time measuring unit 522a is started, the variable N indicating the set time number is set to 1 and the set number of times K is acquired from the set time table (S501; YES, S502, S503). .

Next, the N-th set time is acquired from the set time table, and it is determined whether or not the total elapsed time input from the total elapsed time measuring unit 522a and the set time match (S504, S505). . When the set time and the total elapsed time do not match, the process returns to step S505 and is repeated until the set time and the total elapsed time match (S505; NO). When the set time and the total elapsed time match, a time matching signal indicating that they match is output to the vibrating unit 27 (S505; YES, S506). The vibration unit 27 vibrates the mobile terminal 2 when the time coincidence signal is input from the set time determination unit 28.

Next, in step S507, it is determined whether or not the variable N and the number of set times K match, and if they match, it means that the determination for all the set times has ended, and the processing ends. Yes (S507; YES). On the contrary, if they do not match, it means that there is a set time that has not been determined. After adding 1 to the variable N, the process proceeds to step S504, and the process is performed for the Nth set time (S50).
7; NO, S508).

In this way, since the portable terminal 2 vibrates by the vibrating section 27 when the entire elapsed time reaches the set time,
The presenter can grasp the progress of the presentation to some extent without looking at the display unit 21 of the mobile terminal 2. In particular, since the presenter normally carries the portable terminal 2 and operates the projector 1 remotely, such notification by vibration is very effective. Further, in the method of notifying the presenter by vibration, for example, even if the mobile terminal 2 vibrates during the presentation, the listener of the presentation does not notice the vibration sound and the listener can concentrate on the presentation.

3. Others a) The vibration unit 27 can notify the presenter of the same number of vibrations for all the set times, for example, but in this case, it is difficult to know which set time the presenter is. Therefore, quoting the previous example, 5
At the time of minute, it vibrates once with "Brutsu", and vibrates twice with "Brutsu, Brutsu" 9 minutes before the end of the minute, and with "Buru, Brutsu ..." at the end time of 10 minutes. Vibrates continuously,
The presenter may be notified so that the difference in the number of vibrations can be recognized. In this way, by changing the number of vibrations depending on the set time, the presenter can associate the set time with the number of vibrations, and easily grasp the progress status of the presentation without looking at the display unit 21 of the mobile terminal 2. can do.

B) In the above fifth embodiment, the time to be notified to the presenter is set to the presentation time of the presentation, but it may be set to the scheduled time of each image. As such an example, there is a case where the mobile terminal 2 vibrates when 30 seconds remain with respect to the scheduled time allotted for the image presentation. Of course, even if the notification is made for each image in this way, the same effect as described above can be obtained.

C) In the fifth embodiment, the vibrating section 27 for vibrating the portable terminal 2 is used as a means for notifying the presenter. However, another notifying means, for example, generating a notification sound for generating a notification sound or the like. Parts may be used. Thus, even if the notification by vibration is changed to the notification by voice, the presenter can know that the entire elapsed time has reached the set time. In this case, it can be implemented by replacing the vibrating section 27 of FIG. 12 with an alarm sound generating section.

Furthermore, even if the vibration and the warning sound are used together,
The same effect as that of the embodiment is obtained. Also, the number of warning sounds and the type of warning sound may be changed depending on the set time, as in the case of the above a).
You may make it notify by an electronic sound like this. d) In the fifth embodiment, the set time is input by the input key, but for example, as in the third embodiment, the set time is input by the PC 4 and the set time is input. It may be attached to the presentation file and transmitted to the set time storage unit 29 of the mobile terminal 2 via the projector 1.

(Sixth Embodiment) Next, the sixth embodiment of the present invention will be described.
The embodiment will be described. In the first to fifth embodiments described above, the presenter can easily grasp the time information during the presentation, but how many minutes it took to present each image after the presentation or what time distribution was made. It is very difficult to remember that. Especially in the case of prior training, it is important to keep a history of how each image is switched with respect to time.

Normally, in order to keep a record of such a lapse of time, it was necessary to ask a person other than the presenter to record it. Also, the person who records the passage of time cannot concentrate on the content of the presentation because he / she needs to concentrate on the time recording. Therefore, in the present embodiment,
A case where a history recording the switching time of each image is left will be described.

1. Configuration of Mobile Terminal In the present embodiment, the mobile terminal 2 is provided with a history storage unit 31 for storing elapsed time. FIG. 14 is a functional block diagram showing the configuration of the mobile terminal 2 according to the fifth embodiment. The configurations of the projector 1 and the PC 4 are the first
Since it is the same as that described in the above embodiment, the illustration and detailed description thereof are omitted here.

When the image switching signal from the presenter is input from the operation unit 5, the history storage unit 31 determines the total elapsed time when the image switching signal is input as the total elapsed time measuring unit 5.
22a and stores it. Specifically, the history storage unit 31 includes a history table, and the history table sequentially stores the times acquired from the total elapsed time measuring unit 522a.

The history stored in the history storage unit 31 is
It is configured to be displayed on the display unit 21 of the mobile terminal 2 by operating the presenter. Specifically, the presentation ends and the presenter selects the selection key 53.
When the history display mode in which the history is displayed on the display unit 21 is selected by operating the etc., the time recorded in the history table is displayed.

FIG. 15 is a diagram showing a state in which the history result is displayed on the display unit 21 of the mobile terminal 2. As shown in the figure,
Regarding the images used for the presentation, for example,
It can be seen that the first image is switched after "1:45" from the start of the presentation and the second image is switched after "2:10". further,
It can be seen that the presentation time required for the presentation was "9:55" even after the presentation.

2. Description of Operation of Mobile Terminal The operation of the mobile terminal 2 having the above configuration will be described below. FIG.
3 is a flowchart showing the processing contents of the history storage unit 31 of the mobile terminal 2. The history storage unit 31 starts processing when the presentation start mode is selected by the presenter. If the presenter operates the operation unit 5, it is determined whether the operation is an image switching operation (S601; YES, S602). When the operation is an image switching operation, the total elapsed time measuring unit 522a
The time is acquired from the table, the acquired time is stored in the history table, and the process proceeds to step S601 (S602; YE).
S, S603).

If the operation content is not the image switching operation in step S602, it is determined whether the operation is an operation of turning off the projection power source (S602; NO, S60).
4). Then, in the case of an operation of turning off the projection power supply, that is, a signal indicating the end of the presentation, the time at the end is acquired from the total elapsed time measuring unit 522a, the acquired time is stored in the history table, and the process ends. Yes (S604; YES, S605). Conversely, turn the projection power
If it is not the FF operation, that is, if the presentation is continuing, the process proceeds to step S601.

As described above, since all the signals from the operation unit 5 are input to the history storage unit 31, the projection power is turned on / off.
It is possible to easily grasp the operation for F and the operation for switching the image. Therefore, when a signal is input to the history storage unit 31 by the image switching operation and the projection power OFF operation, the time is acquired from the total elapsed time measuring unit 522a, so that the history of the presentation time can be easily recorded. You can

Since the entire elapsed time of the presentation and the time when each image is switched are stored as the history of time passage, the presenter can look at the results recorded in the history storage unit 31 later to display each image. It is easy to review the allocation of the presentation time, and it can be used for the next presentation opportunity. 3. Others a) In the sixth embodiment, the history storage unit 31 is provided in the mobile terminal 2, but it may be provided in the projector 1. However, in this case, since the projector 1 does not have a time measuring unit, means for acquiring the time is required. As such means, there is a method of providing a time measuring unit in the projector 1 or receiving time together with a control signal from the mobile terminal 2.

In the former case, the communication unit 1 of the projector 1
When 6 receives the control signal, the control signal is analyzed, and in the case of the image switching signal, the time may be acquired from the time measuring unit and the time may be stored. In the latter case, when the image switching signal is input from the operation unit 5, the communication unit 26 of the mobile terminal 2 acquires the time when the signal is received from the total elapsed time measuring unit 522a and receives the image switching signal. The time is transmitted to the communication unit 16 of the projector 1.
In response to this, the projector 1 may store the received time as a history in the history storage unit.

When the presenter refers to the history stored in the history storage unit 31 in the projector 1, the presenter sends the history to the portable terminal 2 via the communication unit 16 of the projector 1. In response to this, the mobile terminal 2 outputs from the communication unit 26 to the display unit 21. This allows the presenter to
The history stored in the projector 1 is stored in the portable terminal 2

It can be realized by using a recording medium such as a flexible disk. However, in this case, the projector needs a reading device for reading a file from the storage medium. Of course, it is possible to attach the set time, the scheduled time, etc. to the presentation file.

(3) In each of the above embodiments, the portable terminal is used to remotely operate the projector. However, for example, a conventional remote controller can be used. However, the conventional remote controller includes a time measuring unit that measures time according to the operation content of the operation unit of the presenter, and a display unit that displays time information based on the time measured by the time measuring unit. The difference is that.

(4) In each of the above embodiments, the time information relating to the presentation is the total elapsed time from the start of the presentation, the image elapsed time after each image is displayed, and the remainder obtained by subtracting the image elapsed time from the scheduled time. Although the time is displayed directly on the display unit, another display method may be used. For example, as the information indicating the remaining time, the elapsed time with the scheduled time being 100 may be displayed in%, or a so-called indicator may be displayed using a bar graph, a pie graph or the like.

Further, for example, the background color of the display unit is set to be blue at first, and is changed to yellow when the remaining time is 3 minutes to the presentation time, and is changed to red when the remaining time is 1 minute. You may display so that the progress situation of may be notified by color. The remaining time is calculated by subtracting the elapsed time from the scheduled time in the remaining time calculation unit. However, if the scheduled time is input, the time obtained by counting down the set time may be displayed as it is as the remaining time. In the present invention, such a countdown type time measuring unit is also included in the time measurement.

(5) In each of the above embodiments, the remote controller (portable terminal) is provided with a time measuring unit for measuring time according to the operation content of the operation unit of the presenter, and the time measured by this time measuring unit is set. The time information based on is displayed on the display unit of the remote controller. However, the display unit of the remote controller may acquire the time measured according to the content of the operation unit of the presentation from other than the remote controller. As such an example, it is conceivable that the projector is provided with a time measuring unit, the time measuring unit measures time according to a control signal by the operation of the remote controller, and transmits the measured time to the remote controller. In this case, the time acquisition unit serves as a reception unit of the remote controller, and the display unit displays time information based on the time received by the reception unit.

(6) In the above embodiment, the presentation file is described as being created / edited by the presentation software or containing JPEG format image data. However, other format data may be used. For example, data created by word processing software may be used. However, when using data in other formats, it is necessary to install data conversion software in the image display device.
