[Conventional technique v#] Traditionally, in presentations at academic conferences, lectures, etc., in order to deepen the understanding of the listeners, a manuscript (hereinafter referred to as a presentation manuscript) with characters, figures, etc. written on it that describes the main points of the explanation is used. Equipment that copies the presentation onto transparent film and enlarges it using optical methods, and equipment that photographs the presentation manuscript with a video camera and displays it on a television monitor, etc., have been used. However, with these devices, the presentation manuscript must be prepared manually, which makes it time-consuming to prepare the presentation manuscript. Furthermore, the presenter or another operator had to exchange presentation manuscripts during the presentation, making it impossible to give a smooth presentation.

Therefore, recently, instead of these devices, presentation paper manuscript data is created, edited, and recorded using a computer's character and graphic drawing functions, data recording function, and data display function, and the recorded presentation manuscript is A presentation system has been proposed that allows for smooth screen exchange during presentations by displaying data in the order of presentation.

Image data such as created characters, figures, and natural images are recorded in a large-capacity storage device, and the order (scenario) in which the recorded image data will be displayed is registered in a computer.

However, with the above conventional technology, only one presentation manuscript data is required.

and screen switching procedures can be registered as a scenario, but the execution time of each step was not taken into account. It may take a long time to read from a large capacity storage device such as. In such a case, with the prior art, it was not possible to give a smooth presentation without registering a complex scenario that took into consideration pre-reading and recording of image data in a faster memory, etc.6 The purpose of the present invention is to The object of the present invention is to solve the above problems and provide an image information display device that can realize a smooth presentation by automatically processing processes that would slow response when processed in real time using a simple scenario description. .

In this device, when image data is prefetched by the display procedure advance execution means, the storage location of the prefetched image information is determined according to the usage status of a plurality of memories capable of storing the prefetched image information and a predetermined priority order. A memory acquisition means may be provided for determining the .

Preferably, a preceding execution interrupt means is provided which interrupts the execution of the display procedure preceding execution means and transfers control to the display procedure execution means.

[Function] In an image information display device for giving a presentation, presentation image information created in advance is recorded in a mass storage device such as an optical disk. On the other hand, all presentation display procedures are not executed continuously, but execution is frequently interrupted in accordance with the explanation. Therefore, in the present invention, this execution interruption time is used to advance display procedures (for example, load instructions) that require time to execute. For this purpose, one image information is read in advance and read in advance to the display memory where it is displayed first or to another high-speed memory. This makes it possible to give a smooth presentation.

Hereinafter, typical effects of the present invention using specific implementation means will be explained.

The image data recording means records image data used for presentations. The display/drawing control means controls the drawing of figure data and character data on the display memory means,
Controls screen switching by the screen switching means. The display means displays the image data output from the screen switching means. The scenario registration means registers the procedure for giving a presentation as a scenario. The instruction input means receives the operator's instructions and transmits them to the scenario execution management means. The scenario execution management means interprets and executes processing according to the scenario registered in the scenario registration means. At this time, the scenario is automatically read ahead and executed in the image data read ahead mode of the image data by a specific command that interrupts the execution of the scenario, and when an instruction signal is input from the instruction input means, the scenario is automatically executed. Switch the execution mode to return to time execution.

The image data prefetch processing means is a scenario execution management means that prefetches image data in the image data prefetch execution mode, allocates a recording destination based on memory usage status and data transfer rate, and performs image data prefetch processing. The CPU means controls the entire system.

With the above-described operations, it is possible to realize an image information display device that realizes a smooth presentation by automatically performing processing with a slow execution speed first with a simple scenario description.

[Example] First, a first embodiment of the present invention will be described in detail.

In the figure, 1 is an image data recording unit that records image data for presentations, 2 and 3 are display memories that temporarily record image data for displaying the image data, and 4 is a display memory 2. Alternatively, a screen switching unit selects the image data recorded in the display memory 3 and performs display processing such as fade-in and fade-out; 5 is a display that displays the image data selected and displayed by the screen switching unit 4; 6 is a display A display/drawing control section controls the display and drawing of the display memories 2 and 3 and the screen switching section 4, a scenario registration section 7 registers the presentation procedure as scenario data, and an input section 8 receives instructions from the operator. An instruction input section 9 is a scenario execution control section that controls scenario execution according to the scenario registered in the scenario registration section 7 and the operator's instructions input to the instruction input section 8; An image data prefetch processing unit performs prefetch processing of image data when in data prefetch mode; 11 is a CPU that controls the entire system; 12 is a general-purpose memory of the system; 13 is for exchanging data and control commands for each part of the present invention. It is a system bus.

First, image data for making a presentation is imported and edited externally, and is registered in the image data recording section 1. At this time, one image data includes image data attributes (data amount, display position, display range).

(color information, etc.) and a file name to distinguish the image data are also recorded. With this, when a load command and a file name are specified in a presentation scenario, image data that corresponds one-to-one to the given file name can be retrieved and displayed based on the attributes of the image data.

Next, a circuit for displaying, drawing, and switching image data will be explained using FIG.

Reference numeral 21 denotes a display control circuit for controlling the reading of image data temporarily recorded in the display memories 2 and 3 in accordance with the display operation of the display 5, and 22 indicates an image temporarily recorded in the display memories 2 and 3. A drawing control circuit that rewrites data, 23 a screen switching processing circuit that selects and processes image data output from the display memories 2 and 3 by the display control circuit 21, and 24 a screen control circuit that controls the screen switching processing circuit. 25 is a digital/analog (D/A) conversion circuit that converts the image data selected and processed by the screen switching processing circuit 23 into an analog signal; 26 is a horizontal/analog (D/A) conversion circuit output from the display control circuit 21;
A vertical synchronization signal 27 is a display signal output from the D/A conversion circuit.

First, 1 display control circuit 21 includes display memory 2 and display memory 3.
The image data temporarily recorded on the display 5 is read out periodically in accordance with the rask scanning of the display 5, and at the same time, horizontal synchronization signals and vertical synchronization signals necessary for the display operation of the display 5 are also generated and output. I'm doing it. In addition, by changing the read position and read timing of the display control circuit 21, image data panning (display processing that changes the display position of image data) and window display (
Display memory 2 and display memory 3, which are capable of displaying only part of the image data (display processing for displaying only part of the image data), output the temporarily recorded image data according to the readout control of the display control circuit 21. The double-sided switching circuit 23 switches between the image data output from the display memory 2 and the display memory 3, and processes the image data itself.

Fade out (screen switching process where the screen gradually becomes darker), fade in (screen switching process where the screen gradually becomes brighter), and dissolve (the currently displayed screen gradually fades and the primary screen gradually appears) (Screen switching processing that changes the screen), cut (screen switching processing that instantly switches between the currently displayed screen and the next screen), and superimpose (switching the displayed screen using only a part of the screen) The 0-screen control circuit 24, which performs display processing during screen switching such as superimposed display processing), determines whether the 1-screen switching processing circuit 23 selects the image data in the display memory 2 or the image data in the display memory 3. It also controls what kind of display processing is performed and how long it takes when switching from the current display screen to the next display screen. The D/A conversion circuit 25 converts the image data processed by the screen switching processing circuit 23 into analog data, adds the horizontal synchronization signal and vertical synchronization signal output from the display control circuit 21, and converts the image data into analog data as a display signal. Send to 5. The display 5 displays the display signal output from the D/A conversion circuit 25. Furthermore, the drawing control circuit 22 directly rewrites the image data temporarily recorded in the display memory 2 or display memory 3 by giving a drawing command (command to draw a straight line, circle, rectangle, etc.), thereby performing drawing processing ( (Draw a straight line, a circle, a rectangle, etc.).

By performing the above operations in each circuit and setting control commands and various data to the display/drawing control section 6, display processing and drawing processing of image data, as well as screen switching processing can be performed. Also.

To control more behavior in presentation scenarios, use pan instructions, window instructions, fade-in instructions,
Write fade-out commands, dissolve commands, cut commands, superimpose commands, etc. together with parameters.

Next, the operation of each circuit for creating, editing, and recording scenario data in the scenario registration section 7 will be explained using FIG.

31 is a keyboard for manually inputting data when creating and editing a scenario; 32 is a memory for temporarily recording input scenario data; 33 is a display for displaying scenario data recorded in the memory 32; 3
4 is a scenario editing department that controls scenario creation and editing;
13 is a system bus for exchanging data and control commands with other circuits, and 35 is a scenario recording unit for storing created scenario data.

First, in order to create scenario data, the scenario creator inputs the various commands described above as scenario data using the keyboard 31 to describe the presentation procedure. The scenario control circuit 34 records scenario data input from the keyboard 31 in the memory 32 and displays the input scenario data on the display 33. Through these operations, scenario data can be created. At this time, the scenario creator takes into consideration the flow of explanation during the presentation and creates a scenario by setting delimiters for each scene.

When giving a presentation, there are parts where one screen changes, and parts where the screen remains the same and the presenter explains the screen, and this combination is used as an explanation unit (a break in which the presenter gives one explanation). At this time, in the presentation scenario, each explanation unit is separated by a break command (hereinafter referred to as a break command).

It is created while adding commands (referred to as pause commands).

Furthermore, in order to edit the scenario data, the scenario creator gives commands such as moving, copying, and deleting one character string to the scenario editing section 34 from the keyboard 31 with respect to the displayed scenario data.

The scenario editing section 34 rewrites the contents of the memory 32 according to the given command, and displays the result on the display 43. This operation allows scenario data to be edited. Finally, in order to record the scenario data created and edited, the scenario creator gives a command to record the scenario data and a scenario name of the scenario data to the scenario editing section 34 using the keyboard 31. The scenario editing section 34 records the scenario data created in the memory 32 in accordance with the given command in the scenario recording section 35 together with the scenario name. By performing the above operations, scenario data can be created, edited, and recorded.

Next, using FIG. 4, the instruction input section 8 for giving presentation instructions by the presenter when giving a presentation will be explained.

Reference numeral 41 refers to a remote control device that the presenter uses to give presentation instructions at hand during a presentation; 42 refers to an operation switch section (copying switch) attached to the remote control device 41 that allows the presenter to provide an instruction to display the next presentation screen; ), 43 is the remote control device 4
1, a receiving circuit 44 receives the instruction signal 43 output from the remote controller 41, and 45 analyzes the instruction signal 43 received by the receiving circuit and passes it to the system bus 13. The presenter is equipped with a remote control in the scenario execution control unit 9! ! This is an instruction control circuit that outputs whether or not the operation switch 42 of 41 is pressed.

The presenter of the presentation holds the remote control device 41 in his hand, faces the receiving circuit 44, and presses the operation switch 42 to issue an instruction to display the next presentation screen.When the operation switch 42 is pressed, the remote control device An instruction signal 43 is output from f41. The receiving circuit 44 receives an instruction signal 43 sent from the remote control device 41.
The receiver receives the information and transmits it to the instruction control circuit 45. The instruction control circuit 45 analyzes the received signal and, if the signal indicates that the operation switch 42 of the remote control device 41 has been pressed, sends a signal to the scenario execution control section 9 indicating that an instruction has been input from the presenter. send.

Next, the relationship between scenario data and actual presentation execution will be explained using FIG.

L1 to Ln are line numbers of commands read by the scenario execution control unit 9 when giving a presentation, M1 is a load command to read and display image data from the image data recording unit 2, and M2 is a presenter's explanation of the image data. It is a command used in cases.

M3 is a pause command that stops the presentation until the presenter inputs an instruction to display the next screen on the instruction input unit 8, M3 is a fade-out command that gradually darkens the currently displayed screen, and M4 is a dim command. M5 is an end command indicating that the presentation scenario has ended. Further, in the load command M1, a file name is specified as a parameter in order to specify the image data to be read from the screen data recording section l.

First, the execution control unit 9 reads the scenario from the first command line (Ll) and executes the presentation scenario. In the example of FIG. 4, the image data with file name 1 is read out and displayed in the first line (Ll). 2nd line (L2)
If the presenter's instructions have not been inputted, a fade-out command is executed in the third line (L3) to gradually darken the display screen. 4th line (L4
) reads the image data with file name 2.

The display screen is dark so it is not actually displayed.
In the fifth line (L5), a fade-in command is executed to gradually brighten the display screen. At this time, the image data with file name 2 is displayed for the first time. Waits for an instruction input from the presenter on the 6th line (L6) 0 If the presenter inputs an instruction, the image data with file name 3 is read out and displayed on the 7th line (Ll) 2 or more As shown in FIG. 2, the instructions in each line are executed, and when the end instruction is executed in the last line (Ln), the execution of the presentation scenario ends. At this time, if the scenario execution control section 9 does not perform pre-reading control of image data and reads out the image data from the image data recording section 2 every time a load command is issued, the image data will be kept waiting every time a load command is executed. Therefore, the image data is read in advance using the time when the presentation is temporarily stopped (the time when the presenter is explaining the image data).

Next, when giving a presentation using FIG. 6, how does the scenario execution control section 9 perform automatic prefetch control during scenario execution based on the scenario data from the scenario registration section 7 and the instruction input signal from the instruction input section 8? or explain.

The scenario execution control unit 9 controls presentation execution and automatic prefetching when presentation execution is stopped using an execution pointer ep that indicates the command line of the current presentation data and a prefetch pointer sp that indicates the command line that is being prefetched. is being carried out.

(Hereinafter, blank space) First, the scenario execution control unit 9 points the execution pointer ep
and read ahead pointer sp to the first line of scenario data (Ll
), then initialize to (SL).

The instruction on the instruction line (Ll) pointed to by the execution pointer ep is read (S2). Next, determine whether the read instruction is the instruction at the end of the scenario data (end instruction) (S3)
Then, when the end command is issued (S3: YES), the execution of the scenario data is ended.

Also, if it is not the final command (S3: No),
It is determined whether it is a command to temporarily stop the execution of the scenario (in the case of the scenario shown in FIG. 5, it is a pause command) (S4).

When it is a pause command (S4: YES), the image data prefetch routine (Jl) is performed until the command input signal is input from the command input unit 8, and when it is not a pause command (S4
: When the read instruction is executed (S5), it is determined whether the execution pointer ep and the read-ahead pointer sp are equal (S6).
ES), the instruction line pointed to by the execution pointer ep and look-ahead pointer sp is advanced by one (S7), and when they are not equal (S6: No), the instruction line pointed to by the execution pointer ep is advanced by one (S7). Next, the instruction on the instruction line (L2) pointed to by the execution pointer ep is read (S2
).

By repeating the above operations, presentation commands are executed until the end of the scenario data.

Next, a look-ahead routine (Jl) that is executed when presentation execution is paused will be described. If "YES" in the previous process S4, the process moves to the image data prefetch routine (Jl).

First, the instruction on the instruction line pointed to by the read-ahead pointer sp is read (S9), and then it is determined whether the read instruction takes time to execute (in the scenario of Figure 5, it is a load instruction) (SIO). Then, load command (S10:
When the answer is YES), the scenario execution control unit 9 instructs the image data prefetch processing unit 10 to prefetch image data (S).
14).

When the image data prefetching processing unit 10 receives the image data prefetching command, it determines the memory with the highest priority that has free memory space at the moment, transfers the image data to that memory, and displays the transfer result (used memory, its address information, etc.) is returned to the scenario execution control unit 9. The scenario execution control unit 9 rewrites the load instruction in the command line indicated by the scenario data prefetch pointer with prefetched information based on the results processed by the image data prefetch processing unit 10 (S
15).

If it is not a load instruction (SIO: N○), determine whether the read instruction is the end instruction (end instruction) of the scenario data (Sll) L, te, end instruction (S 11:
If the answer is YES), skip the process S12 and proceed to the next step. If it is not the end command (311: N○), advance the read-ahead pointer by one (512), and then issue an instruction from the instruction input unit 8. Determine whether the input has been input (S1
3) Do it.

When an instruction input has been input (S13: YES), the prefetch routine (Jl) is ended, and at the same time, execution of the presentation is started. Furthermore, when no instruction input is input (S13: N○), the instruction in the instruction line indicated by the prefetch pointer sp is read (S13: N○).
9).

By repeating the above operations, the presentation image data prefetch routine is executed until an instruction input signal is input from the instruction input section 8.

Next, using FIG. 9, the rewriting process S15 of the prefetch routine is performed.
An example of this will be explained.

In the figure, L1 to Ln and M1 to M5 are the same as those explained in FIG. M6 is a screen switching command that turns the currently displayed display memory OFF and turns on the display memory that has not been displayed so far. Also, E
P indicates the position indicated by the execution pointer, and SP indicates the position indicated by the prefetch pointer.

Here, when the scenario data shown in FIG. 5 is being executed, when the execution pointer EP points to L2 and the read-ahead pointer SP points to L4, the image data read-ahead process S], 4 is performed in response to the load command. executed. At this time 1
If display memory 2 is used for display and display memory 3 is unused, image data is transferred to display memory 3.
Next, in the scenario data rewriting process S15, the command indicated by the prefetch pointer SP is rewritten into a screen switching command for switching the display memory from the display memory 2 to the display memory 3, as shown in FIG. By rewriting the scenario data through such pre-reading processing, the execution pointer can execute the L4 screen switching command, thereby realizing switching of the display screen much faster than the load command.

Note that if the first display memory 3 is also unavailable due to reasons such as holding the next screen, the next priority memory is used. In that case, instead of the instruction 6, a transfer instruction (not shown) from the memory to the display memory is prepared.

Next, the image data prefetching process performed by the image data prefetching processing section 10 will be explained using FIG.

71 is based on the data transfer rate of each medium when image data is transferred from an image data recording medium such as the image data recording unit 1, the display memories 2 and 3, and the system memory 12 to the display memories 2 and 3 or the system memory. 72 is a display memory 2, which is a priority setting unit that sets priorities in descending order of priority;
, 3 and the memory usage status registration unit 73 in which the usage status of the memory of the present invention, such as the system memory 12, is always registered. A writable memory acquisition circuit 74 acquires a memory area for writing data, and an image data prefetch execution circuit 74 reads and records image data from the image data recording unit 1 in the memory acquired by the writable memory acquisition circuit 73.

First, an image data prefetch command is sent from the scenario execution control section 9 to the image data prefetch processing section 1o. The writable memory acquisition circuit 73 checks the memory usage statuses registered in the memory usage status registration unit 72 in order of priority given by the data transfer time calculation unit 71, and acquires usable memory. 0 Next, the writable memory acquisition circuit 73 passes the acquired memory to the image data prefetch execution circuit 74 1 The image data prefetch execution circuit 74 records the image data according to the memory information passed from the writable memory acquisition circuit 73 The data is read from part 1 and recorded in the acquired memory. In addition, a data transfer time calculation section (not shown) is provided that calculates the data transfer time of each memory based on the data amount of the sent prefetch image data and prioritizes the memories in descending order of transfer time. Good too.

Furthermore, the memory in which the image data is preread and recorded is registered in the memory usage status registration unit 72, and the execution results are returned to the scenario execution control unit 9.The memory usage status registration unit 72 also constantly monitors the memory usage status. When the memory is no longer used, the memory usage registration is deleted. If available memory cannot be acquired, do nothing and exit.

By performing the above operations by the image data prefetch processing unit 10, the image data is prefetched while automatically selecting and acquiring the memory that can display the earliest available image data based on the image data transfer rate. You can.

This embodiment adopts a configuration as shown in FIG.

During a presentation, you can use the time when the presentation is temporarily suspended while waiting for input instructions from the presenter to process processes that would be slow to respond if processed in real time (especially 1).
It is possible to realize an image information presentation device that automatically acquires an optimal storage area for image data reading (image data reading) and performs prefetch processing of image data, and provides a smooth presentation with a simple scenario description.

Although the above-described embodiment has two display memories, display memory 2 and display memory 3, the essence of the present invention is not changed even if there is only one display memory unless special effects are performed when switching between 5 screens. In addition to the illustrated memory, a memory dedicated to pre-reading may be provided.

The display 43 of the scenario registration section 7 is not necessary if the scenario data is displayed on the display 6.

Although the image data recording section 1 and the scenario registration section 7 are described as recording in different recording devices, the same effect can be obtained even if they are recorded separately in one recording device.

Data transfer time calculation unit 7 of image data prefetch processing unit 10
If 1 is used only to determine the priority order of memory to be used, it is sufficient to set the priority order based on the data transfer rate of each memory, and no arithmetic function is required.

Next, a second embodiment will be described below using FIG. 8.

FIG. 8 is a block diagram of the image information display device according to this embodiment. In FIG. 8, components denoted by the same reference numerals as in FIG. 1 indicate the same components.

In the figure, a newly added block 80 is an interrupt control unit that performs interrupt control on the image data prefetch processing unit 10 when an instruction is input to the instruction input unit 8;
Reference numeral 81 denotes an interrupt processing compatible scenario execution control unit that is capable of controlling scenario execution when the image data prefetching processing unit 10 is interrupted midway due to an interrupt. This is because if the image data prefetch processing unit 10 is prefetching a large amount of image data while the presentation is paused, even if the presenter inputs an instruction to the instruction input unit 8, the image data prefetch processing unit 10 The presentation may not be paused until the prefetch process is completed, and the presentation may not be able to be performed smoothly. Therefore, when the presenter's instruction input is input to the instruction input unit 8, the 1 interrupt control unit 80 performs an image data prefetching process that interrupts the image data prefetching processing unit 10 to interrupt the image data prefetching process. The interrupt control unit 8 is connected to the unit 10.
When an interrupt is input from 0, the image data prefetch execution circuit 7
If pre-reading of image data is being executed in step 4, the pre-reading of one image data is interrupted, the state at the time of interruption is registered in the memory usage status registration unit 72, and the image data is sent to the interrupt handling compatible scenario execution control unit 81. Notifies that pre-reading has been interrupted.

The scenario execution control unit 81 supports interrupt processing.

When the image data prefetching process is interrupted, the scenario data of the instruction indicated by the prefetch pointer sp is rewritten so that the information at the time of the interruption is valid.

The suspension of the presentation is canceled without advancing the read-ahead pointer by one, and the instruction indicated by the execution pointer ep is executed. At this time, if the instruction indicated by the execution pointer ep is an instruction that interrupted the prefetch execution of image data, the instruction is executed after the prefetch execution of five image data is completed. When the next pause command is executed while a presentation is being executed, the presentation is paused and image data prefetch processing is executed. At this time, since the prefetch pointer sp indicates the command when the image data prefetch process was interrupted, the continuation of the image data prefetch process is executed. As a result, even when prefetching image data is being executed during a presentation, if an instruction input is input to the instruction input section 8, the presentation can be immediately released from the pause and the execution of the presentation can be resumed.

[Effects of the Invention] As explained above, the present invention has the advantages of slow execution speed processing (
Load command) is automatically prefetched when the presentation is paused (when the presenter is displaying the display screen), and the prefetched image data is automatically executed when the prefetch process is performed. By automatically allocating memory to the memory that can be displayed the fastest, it is possible to create highly responsive presentations without consciously creating scenario descriptions.
