Although it is provided with an arithmetic processor and the like, these components are the same as those of a general computer, and are omitted to simplify the description.

The material presentation device 20 of the present embodiment configured as described above stores the following various control programs in its ROM 52, and executes material presentation to the viewer.

FIG. 3 is a flowchart of a material presentation program that is processed by the CPU 50 at the same time when the power of the material presentation device 20 is turned on. When entering the processing of this program, the CPU 50 first inputs the image information of the captured image from the CCD camera 26A (step 100).
It is determined whether the operation mode instructed through the operation unit 2 or the operation unit 30 is the normal mode or the combination mode (step 1).
10). When it is determined that the operation mode is the normal mode, the CPU 50 displays the image information input from the CCD camera 26A on the built-in monitor 40 and outputs the same image information from the external image output terminal 66. To the image processing circuit 60 (step 120).
One process of this program ends. That is, the material presentation device 20 of the embodiment when the operation mode is the normal mode performs the same function as the conventional material presentation device, and is displayed on a large monitor (not shown) connected to the external image output terminal 66. The same image as the image can be visually recognized through the small built-in monitor 40.

On the other hand, when the composite mode is instructed as the operation mode by operating the keyboard 32 or the like, the composite image output processing (step 13) unique to the present embodiment is performed instead of the step 120 by the determination processing of the step 110.
0 to 150) are executed.

When the CPU 50 enters the composite image output process, the CPU 50 reads out the image information of the support image allocated to a predetermined area of the RAM 54 (step 130), and reads this support image information and the image information input from the CCD camera 26A. The images are synthesized according to a predetermined rule (step 140), and the synthesized image is output to the built-in monitor 40 (step 150). At this time, only the image information input from the CCD camera 26A is output from the external image output terminal 66 as in step 120. That is, by the composite image output process, not only the image information input from the CCD camera 26A but also the support image stored in a predetermined area of the RAM 54 is synthesized and reproduced on the built-in monitor 40.

Next, a process of generating a support image used in the composite image output process will be described. FIG. 4 is a flow chart of a time setting program which terminates or interrupts the material presentation program shown in FIG. 3 when a predetermined key input is made. When the time setting program is processed, the CPU 50 uses the built-in monitor 40 to set time information for using the material presentation device 20,

The information of the start time and the end time stored in the predetermined area of No. 4 is read (step 300), and a time support image is generated from the information and the current time managed as system information (step 310). The time support image is stored in a predetermined area of the RAM 54 which is scheduled to be read out in step 130 of the material presentation program (step 320). That is, the time support image generated by this time support program and the CC
The composite image with the image captured by the D camera 26A is displayed.

FIG. 6 is an explanatory diagram showing an example of a composite image displayed on the built-in monitor 40. This composite image is executed when the composite mode of the material presentation program (FIG. 3) is selected. As shown in the figure, most of the image on the built-in monitor 40 is used as an area for displaying image information from the CCD camera. At the right end, the current time (PM3: 15 in the figure) is displayed and the start time is displayed. The elapsed time is visually displayed on a bar graph starting at the time (PM 2:00 in the figure) and ending at the end time (PM 4:00 in the figure).

The material presentation device 20 of this embodiment can also store a character support image in a predetermined area of the RAM 54 that is to be read in step 130 of the material presentation program.

FIG. 7 is a flowchart showing a character support program for writing a character support image in the predetermined area. This program is executed when the combination mode is instructed similarly to the time support program and the condition that significant character string information is stored in a predetermined area of the RAM 54 is satisfied.

In this program, first, n pages (n is a natural number starting from 1) from character string information over a plurality of pages.
Is read out (step 400).
A character support image is generated from the character string information (step 4).
10) The generated character support image is stored in a predetermined area of the RAM 54 which is scheduled to be read in step 130 of the material presentation program (step 420).
Then, it is determined whether there is a page break input (step 430).
Only when a page break is input, the variable n is incremented by one (step 440), and the process returns to step 400. That is, by executing the material presentation program of FIG. 3 after the processing of this program, the image displayed on the built-in monitor 40 changes to a composite image of the image from the CCD camera 26A and the character support image. .

FIG. 8 is an explanatory diagram of the display on the built-in monitor 40 when the character support image is synthesized. In this case,
Character string information stored in a predetermined area of the RAM 54 is displayed at the right end of the screen, and it is possible to visually recognize both the image of the CCD camera 26A and the character string information at the same time.

In order to write the character string information into a predetermined area of the RAM 54, an editor or a word processor program is processed by the CPU 50 and the keyboard 3
Any method can be used, such as directly keying from step 2 or transferring character string information created by another device to a predetermined area of the RAM 54.

Step 13 of the material presentation program
If both the time support image and the character support image are stored in the predetermined area of the RAM 54 that is scheduled to be read at 0, the image synthesis processing in step 140 is performed by three images including the image from the CCD camera 26A. Is performed. FIG. 9 shows a display example of the built-in monitor 40 by the synthesis processing of these three images. In this case, the CCD camera image area shown in FIG.
The time support image is arranged in a small area below the screen, and the character support image is arranged in the same manner as the display area in FIG.

By inputting the start time, the end time, and the character string information in a predetermined area of the RAM 54 in advance, the operator of the material presenting device 20 adds, in addition to the image input from the CCD camera 26A, the built-in monitor 40 of the material presenting device 20, These time and character images can be displayed simultaneously. Therefore, the operator confirms the image on the built-in monitor 40 to check the CCD camera 2.
In addition to the image of 6A, it is possible to easily obtain image information that assists in matters to be explained with respect to the image presented to the viewer, and provides explanations, lectures, classes, and the like, which are the objects of using the material presentation device 20. Can proceed smoothly.

In particular, when the image information to be supported is a time support image, there is no need to prepare a separate clock, and it is not necessary to read the clock by diverting the line of sight from the material presenting device 20 or the viewer. Information about time. In addition, the time support image of the present embodiment displays the use time and the elapsed time of the material presentation device 20 in a graph as shown in FIGS. For this reason, even if the display screen of the built-in monitor 40 is small, the elapsed time can be grasped instantaneously, and the time distribution for ending the explanation to the viewer within the scheduled time can be intuitively understood. it can.

When the image information to be supported is a character support image, dictate without fail to forget items to be explained with respect to the image shown to the viewer without preparing a separate memo or the like. Can be. Moreover, since the character support image is displayed on the built-in monitor 40 of the material presentation device 20, it is not necessary to deviate the line of sight from the viewer as when checking a memo or the like on a desk.

Further, the material presenting apparatus 20 configured as described above allows the video to be displayed only on the built-in monitor 40 in advance by operating the operation unit 30 as appropriate without displaying the video on the television directed to the viewer. By confirming, an erroneous image is not displayed on the television side, and the image can be easily corrected.

The embodiments of the present invention have been described above.
The present invention is not limited to these embodiments at all, and it is needless to say that the present invention can be embodied in various modes without departing from the gist thereof. For example, in the above-described embodiment, an example is shown in which the built-in monitor 40 is of a retractable type and the screen can be easily reduced in size.
Even if it is embedded type in 0, it does not matter. Further, in the embodiment, the example in which the time support image is displayed using the bar graph format in order to make it easy to understand intuitively has been described, but the elapsed time and the remaining time may be numerically displayed.

In the above embodiment, the image processing circuit 60
In order to reduce the information processing load, a split method is used to create a composite image, but images can be superimposed and the display area of each image can be changed, enlarged, or reduced using a pointing device such as a mouse The image processing technique such as described above may be appropriately adopted.

Further, among the plurality of support images, the operation unit 3
The display may be selectively displayed on the television of the viewer by the operation of 0. For example, unnecessary time information for the viewer can be selectively removed by displaying only the built-in monitor 40 without displaying the time support image unnecessary for the viewer on the television of the viewer.
