[0012]

Usually, a presentation has a time limit, and the presentation must be completed within this time limit. For this reason, the time allocated to one still image is scheduled to determine the pace distribution of the presentation. However, for example, when the pace distribution is broken due to taking too much time for one still image, the still image to be displayed must be omitted in order to finish the process within the time. At this time, there is a problem that it is difficult for the presenter to immediately select the still image to be displayed next based on his / her own judgment while considering the remaining time.

Further, even if the presenter determines the priority in advance, it is difficult to properly select the still image to be displayed next. The present invention has been made in view of the above problems, and provides a display still image selection device that automatically selects a still image to be displayed next according to the remaining time according to a preset priority. The purpose is to

[0014]

A display still image selection device of the present invention, in association with a manual operation, an undisplayed still image specifying means for specifying an undisplayed still image after a display commanded still image, Of the undisplayed still images, the total of the next display still image specifying means for specifying the still image with the highest display order as the next display still image and the scheduled display time of the undisplayed still image from the remaining display time is a predetermined time or more. Excluding the detection means for detecting the shortening and the still image of low priority when the output of the detection means is generated, the next display still image is displayed when the still image of low priority is the next display still image. It is provided with an updating means for judging the disqualification and updating the next display still image.

[0015]

In the display still image selection apparatus of the present invention, when the total of the scheduled display times of the undisplayed still images is shorter than the display remaining time by the predetermined time or more, the still image of low priority is the next display still image. The next displayed still image is updated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiment in which the present invention is applied to a display still image selection device will be described below. First, FIG. 1 is a functional block diagram of the controller 12 shown in FIG. Figure 2
FIG. 6 is a diagram showing control information for presentation of the present embodiment. FIG. 3 is a configuration diagram of the image reproduction control unit 26 (the image reproduction control unit 18 and the image processing unit 19) illustrated in FIG.
Each unit except the data storage unit 3 in FIG. 1 is configured by software in the controller 12 (for example, a personal computer) in FIG. 4, and constitutes the controller 12 together with the data storage unit 3.

The control information for this presentation is
Display order data (serial number), video address (disk number, image number), effect data (effect command, parameter), scheduled display time data, priority data,
A table (see FIG. 2) including areas for writing execution flags and determination flags is formed in the data storage means 3.

The display order data is a serial number that determines the order of still images to be displayed in advance when the presenter makes a presentation using still images. For example, the still image with serial number 1 should be displayed first and the still image with serial number 2 should be displayed second. In this case, the presentation is performed using still images with serial numbers 1 to 10.

The scheduled display time data is the scheduled time required to give a presentation to one still image. For example, the still image with the serial number 2 takes 50 seconds, the still image with the serial number 3 takes 30 seconds, the still image with the serial number 4 takes 1 minute, and the still image with the serial number 5 takes 2 minutes and 35 seconds. The priority data is data that determines the priority of a still image to be displayed, for example, that this still image does not have to be displayed, or that this still image must be displayed. In FIG. 2, the images are numbered as 1, 2, 3 in order from the highest priority still image. The priority data may be a stepwise priority by ranking.

The execution flag is used to confirm the progress of the presentation. For example, flag 1 is stored for still images with serial numbers for which display is instructed, and flag 0 is stored for still images with serial numbers for which display is not instructed. The determination flag is used to determine the still image to be displayed next from the still image to be displayed according to the remaining time. For example, as the presentation progresses, the flag 1 is stored for the still images determined not to be reproduced, and the flag 0 is stored for the remaining still images.

Among the control information for this presentation, the display order data (serial number), video address (disk number, image number) and effect data (effect command, parameter) shown in FIG. 5 are displayed on the display device 13 (for example, personal computer). It is displayed on the computer monitor) and the presenter switches the still image while watching it.
The control information to be displayed is not limited to that described above, and scheduled display time data, priority data, etc. may be added.

The operation of the device of the present invention will be described below. The operation before the presentation starts will be described. By operating the input device 15 (for example, a keyboard) illustrated in FIG. 4, the control information for the presentation illustrated in FIG. 2 which is stored in the floppy disk (FD) 24 in advance is changed to a floppy disk drive (FD drive). 14
Is read into the data storage means 3 of FIG. A time limit indicating how long the presentation should be performed is input to the remaining time specifying means 101. However, in the following description, for the sake of convenience, it is assumed that the time limit is set to match the scheduled display time of the presentation program. Also, the data storage means 3
At, the stored execution flag and determination flag are reset to 0.

Now, FIG. 5 is displayed on the display device 13, and using the direction keys of the input device 15, the cursor is moved to, for example, the serial number 1, the serial number 1 is designated, the execution key is input, and the serial number 1 is input. The display of the still image is instructed (manual operation means 1 in FIG. 1). In FIG. 1, the execution flag updating unit 2 (undisplayed still image specifying unit) displays the still image of serial number 1 in the execution flag area of serial number 1 of the control information for presentation stored in the data storage unit 3. A flag 1 indicating that the command has been issued is written. Therefore, in the table in the data storage unit 3, undisplayed still images (still images having serial numbers 2 to 10) after the display-requested still image (still image having serial number 1) are specified.

The display screen data detection means 4 detects a still image (serial number 1) in which the execution flag of the control information for presentation is 1, and all the control information for this still image is stored in the screen data holding means 7. It is input to the first data holding area (not shown) of the two data holding areas. This still image is displayed first. In the next screen data specifying means 5 (next display still image specifying means), the still image detected by the display screen data detecting means 4 (serial number 1)
The still image (serial number 2) in the next display order of is identified,
All control information for the still image of serial number 2 is stored in the second data holding area (not shown) of the screen data holding means 7.
Entered in. Therefore, among the still images that have not been displayed (still images with serial numbers 2 to 10) after the still image for which display instructions have been issued (still image with serial number 1), the still image with the highest display order is specified. This still image is to be displayed next to the still image with serial number 1.

The subsequent screen data specifying means 6 specifies the still image (serial number 3) having the next highest display order after the still image (serial number 2) specified by the next screen data identifying means 5 (next display still image specifying means). Then, all the control information for this still image is input to the third data holding area (not shown) of the screen data holding means 7. This still image will be displayed next to the still image with serial number 2. The first
The data holding area is stored in the first frame memory 194, the second data holding area is stored in the second frame memory 195, and the third data holding area is stored in the third frame memory 195. Control information for specifying a still image to be stored is stored. Area.

In the screen data holding means 7, there are three pieces of control information of the still images specified by the display screen data detecting means 4, the next screen data specifying means 5 (next display still image specifying means), and the screen data specifying means 6 one after another. Each is stored in the data holding area. In the initial state, the first frame memory 19
4, the second frame memory 195 and the third frame memory 196 are reset to the initial state data (for example, a blue still image). First frame memory 19
4, the data of each still image is transferred from the second frame memory 195 and the third frame memory 196 to the first display selection unit 19
7 and the second display selection unit 198. At this time, the image reproduction control unit 18 detects that it is in the initial state, and the first display selection unit 197 causes the first frame memory 194 to operate.
, The second display selection unit 198 selects the second frame memory 198, and the video processing unit 199 simply selects the second display selection unit 198 to cause the high-definition monitor 20 to select the still image in the second frame memory 195 ( (Blue) is displayed.

First, the screen data generating means 8 selects the video address from the data holding area (the first data holding area in this case) in which the control information of the still image with the highest display order is stored before the image switching. And memory data (indicating the first frame memory) corresponding to the data holding area are read out and transmitted to the image reproduction controller 18, as shown in FIG. The video address is input to the video address designating section 192, and the disc number and the image number are designated for the optical disc drive 21. The data (compressed data) of the still image with serial number 1 stored on the optical disc 23 is
The data is input to the decompression unit 193 via the optical disc drive 21 and the compressed data is decompressed. Further, the memory data is input to the frame memory designating unit 191, and the frame memory in which the data of the decompressed still image is stored is designated to be in the storable state. Therefore, the data of the decompressed still image of serial number 1 is stored in the first frame memory 19
4 is stored. From the first frame memory 194, the second frame memory 195 and the third frame memory 196,
The data of each still image is input to the first display selection unit 197 and the second display selection unit 198.

The switching data generating means 9 reads the effect data and the memory data from the data holding area (the first data holding area in this case) in which the control information of the still image with the highest display order is stored, and FIG. As shown in FIG. Memory data (representing the first frame memory) is input to the first display selection unit 197, and the first frame memory 194 is selected. In the second display selection unit 198, the same second frame memory 195 as in the initial stage is selected. The effect data (the effect of the horizontal wipe) is input to the video processing unit 199, and the horizontal wipe image processing is performed from the outputs of the first display selection unit 197 and the second display selection unit 198. Therefore, the still image (blue) of the second frame memory 195 is displayed on the screen of the high-definition monitor 20.
From the first frame memory 194 to the still image (serial number 1) by the effect of the horizontal wipe.

When the images are switched, the serial number 1
Of the still image is displayed on the high-definition monitor 20, the video address and memory data of the still image of serial number 2 is transmitted from the screen data generating means 8 to the image reproduction control unit 18, and the serial number is similarly stored in the second frame memory 195. Data of two still images is stored. Further, similarly, the data of the still image of serial number 3 is stored in the third frame memory 196.

Since the display order data (serial number) of the control information stored in the screen data holding means 7 can identify the still image having the second highest display order (serial number 2) as the still image to be displayed next. At the stage where the still image with serial number 1 is displayed on the high-definition monitor 20, the serial number 2 is indicated by the cursor on the display device 13, and the execution key is awaited.

In this way, the first frame memory 19
The data of the still image with serial number 1 is stored in
The frame memory 195 stores still image data of serial number 3, the third frame memory 196 stores data of still image of serial number 3, and the high-definition monitor 20 stores still image data of serial number 1 (for example, title image). ) Is displayed and preparations are made to start the presentation.

The operation after the start of the presentation will be described below. The presenter inputs a start key indicating the start of the presentation (manual operation means 1) and starts the presentation together with it. The detecting means 10 includes a remaining time specifying means 101 and an adding means 10
2, the subtraction unit 103, the determination unit 104, the sum of the scheduled display time of the undisplayed still image added by the addition unit 102, the remaining time specifying unit 10 with the passage of time
When it becomes shorter than the time limit (remaining time) specified by 1 by a predetermined value or more, it is considered difficult to display all undisplayed still images, and the still images with low priority are deleted. Issue a command to

When the start key is input, the remaining time specifying means 101 counts down the time limit (remaining time) based on the time from the input of the start key to the present and the time limit. In the adding means 102, the scheduled display time data (T
2 to T10) are read and added.

In the subtracting means 103, the output of the remaining time specifying means 101 is subtracted from the output of the adding means 102. In the determination unit 104, the subtraction value output from the subtraction unit 103 is, for example, “0” or more (indicating that the still image with the serial number 1 is displayed too much over the scheduled display time (T1)).
Is detected. For the sake of explanation, the predetermined time to be compared with the subtraction value is set to "0", but the predetermined time is set to a negative value in order to allow time for the description of the next still image. The image may be detected in a state where it does not reach the scheduled time, and this value may be set appropriately.

The updating means 11 is a judgment flag updating means 11
1, a comparison means 112, and an updated screen data forming means 113. Upon receipt of a deletion command from the detection means 10, the still image with the lowest priority is removed from the undisplayed still image, and each data is held by the screen data holding means 7. The control information of the area is checked, and when the control information corresponding to the removed still image is stored, it functions to update the control information.

For example, the still image having the serial number 1 is displayed too much for the scheduled display time (T1), and the determination unit 1
When it is detected that the value is “0” or more in 04, the determination flag updating unit 111 selects the still image (serial number 4) having the lowest priority (priority 10) from the control information read from the data storage unit 3. Upon detection, 1 is written in the determination flag area of the table of the data storage means 3 to indicate that no reproduction is confirmed. As a result, the still image with the serial number 4 is excluded from the objects to be displayed.

The comparing means 112 reads the display order data (serial number) and the memory data from the control information of the still image with serial number 1 stored in the first data holding area, and serial number 1 in the table of the data storing means 3. It is determined whether 1 is stored in the determination flag of. The same determination is made for the second data holding area, and the same determination is made for the third data holding area. At the time when the still image with the serial number 4 is excluded from the objects to be displayed, it is determined that 1 is not stored in the determination flag for the still images with any serial numbers (1 to 3).

On the other hand, in the adding means 102, the scheduled display time data (T2 to T3) of still images which have not been displayed from the data storage means 3 and whose determination flag is 0, that is, the still images excluding the serial number 4. , T5 to T10) are read out and added. Thereafter, the subtraction means 103 performs the same subtraction, and the determination means 104 performs the same detection.

In this state, as before, the display device 13
The cursor displayed on is left at the serial number 2. However, when the still image with the serial number 1 is displayed for more than the time T1 + T4, the determination unit 104 detects that it is “0” or more, and the determination flag updating unit 111 uses the control information read from the data storage unit 3. Then, a still image with the next lowest priority (priority level 9) (serial number 2) is detected, and 1 is written to the determination flag area of the table of the data storage means 3 to indicate that it is decided not to reproduce. As a result, the still image with the serial number 2 is excluded from the objects to be displayed.

The comparing means 112 reads the display order data (serial number) and the memory data from the control information of the still image of serial number 1 stored in the first data holding area, and serial number 1 in the table of the data storing means 3. It is determined whether 1 is stored in the determination flag of. The same determination is made for the second data holding area. At this time, it is found that 1 is stored in the determination flag of serial number 2.

When it is found that 1 is stored in the determination flag of the serial number 2, the update screen data forming means 113
Then, the memory data (indicating the second frame memory) is input from the comparison means 112. From the control information table stored in the data storage unit 3, the update screen data forming unit 113 determines that the determination flag is the second among the undisplayed still images (still images whose display order is after the execution flag is 1). A still image (serial number 5) having 0 is specified, and all control information corresponding to the still image with serial number 5 is read. The control information for the still image with the serial number 5 formed in this way is written in the second data holding area (indicating the second frame memory) of the screen data holding means 7 based on the memory data, and is stored in the screen data holding means 7. The control information is updated. Therefore, the still image of serial number 5 is stored in the second frame memory 194.

As a result, the control information of the still image of serial number 1 is stored in the first data holding area of the screen data holding means 7, and the control information of the still image of serial number 5 is stored in the second data holding area. Control information of the still image with serial number 3 is stored in the third data holding area. Therefore,
According to the display order data (serial number) of the control information stored in the screen data holding means 7, the still image (serial number 3) having the second highest display order is specified as the still image to be displayed next, and the serial number 2 is displayed. Instead of the control information of the still image, when the control information of the still image of serial number 5 is stored in the second data holding area, the cursor displayed on the display device 13 is moved from serial number 2 to serial number 3, and the execution key is pressed. The input waits for.

Now, when the presenter inputs the execution key while the serial number 3 is indicated by the cursor, the execution flag and the determination flag are reset (manual operation means 1). The execution flag updating unit 2 (undisplayed still image specifying unit) indicates that the execution flag of the serial number 3 of the control information for presentation stored in the data storage unit 3 is instructed to display the still image of the serial number 3. The flag 1 shown is written. Therefore, an undisplayed still image (still images with serial numbers 4 to 10) after the still image for which display instruction has been issued (still image with serial number 3) is specified.

The display screen data detecting means 4 is always operated after the initial state since it is clear that the control information of the still image (serial number 3) to be displayed is always stored in the holding means 7 in the screen data. do not do. The next screen data identification means 5 uses the serial number 3 in which 1 is stored in the execution flag.
The control information of serial number 4 following the still image of No. 4 is read from the table of the data storage means 3, and the display order data (serial number 4) of the read control information is the screen data holding area 7.
Exists in. In this case, since it is determined that the data does not exist, the data holding area (first area) in which the control information of the still image (serial number 1) having the highest display order is stored.
In the data holding area), the read control information of serial number 4 is stored. Therefore, the still image with the serial number 4 is stored in the first frame memory 194 instead of the already displayed still image with the serial number 4.

The screen data specifying means 6 one after another has the serial number 4
The control information of the serial number 5 following the still image is read from the table of the data storage means 3, and it is determined whether the display order data (serial number 5) of the read control information exists in the screen data holding area 7. In this case, since it is determined that the control information exists (the second data holding area), the control information of serial number 5 is not stored.

Incidentally, as a result, only one of the next screen data specifying means 5 and the next screen data specifying means 6 functions, and never both of them function. As a result, the control information of the still image having the serial number 4 is stored in the first data holding area, and the serial number 5 is stored in the second data holding area.
Control information of the still image is stored, and control information of the still image of serial number 3 is stored in the third data holding area. In this state, since the image is not switched yet, the high-definition monitor 20 displays the still image of serial number 1.

The switching data generating means 9 is a memory from the data holding means (third data holding means) in which the control information of the still image (serial number 3) having the highest display order among the screen data holding means 7 is stored. The data and the effect data are read out, and the still image with the serial number 1 is switched to the still image with the serial number 3 as described above. The screen data generating means 8 stores a data holding area (first data holding area) in which the control information of the still image (serial number 4) having the second highest display order is stored with the completion of the image switching.
Then, the video address and the memory data are read out, and the data of the still image of serial number 4 is stored in the first frame memory 194 as described above.

Further, the video address and the memory data are read from the data holding area (second data holding area) in which the control information of the still image (serial number 5) having the third highest display order is stored, and similarly, The data of the still image with serial number 5 is stored in the second frame memory 195. After that, the same operation is repeated each time the execution key is input, and the execution flag updating means 2 and the data specifying means (5,
6), the screen data holding means 7, the switching data generating means 9, and the screen data generating means 8 are sequentially operated, and then the detecting means 10 and the updating means 11 are made to function during the period until the execution key is input, so that the time limit is reached. A still image required can be selectively displayed in the display.

The time limit may be set arbitrarily, and may be set to a time much shorter than the total scheduled display time.

[0050]

According to the present invention, when the remaining time of the presentation is insufficient, the presenter does not have to select the still image to be displayed next by his / her own judgment, and according to the preset priority. , It is possible to automatically select the still image to be displayed next according to the remaining time.
