Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a presentation device used at a presentation site such as a conference or a lecture, and more particularly to a presentation device with improved operability.

[0002]

2. Description of the Related Art Recently, in so-called presentation places such as conferences and lectures, an electronic system as a presentation device has begun to appear in place of an OHP (overhead projector), a slide projector, etc., which have been conventionally used as general tools. It was

This presentation apparatus is installed in the apparatus after performing processing such as data compression on a natural image, a character / graphic image, or an image created by combining these images, if necessary. The image is recorded in advance in a recording medium such as an optical disk device, and at the time of presentation, these images are read at high speed and displayed on a monitor or a projector connected to the device. Further, there is a presentation device having a function that can add a special display effect at the time of reproducing an image, so that the impression of the presentation viewer can be deepened.

Further, the presentation device is a kind of image file device in view of the fact that a plurality of images are accumulated and used, but not only the image data but also the reproduction order of images necessary for the presentation and a special display. Reproduction control information such as effects (hereinafter referred to as a scenario) is also recorded as necessary data.

A recording medium such as an optical disk used in this type of apparatus can record several tens to several thousands of images, depending on the type of image, the definition, the presence or absence of data compression, and the like. It is possible. Therefore, it is general that the data of a plurality of presentations are mixed in one optical disc. Therefore, a plurality of scenarios described above should be registered and selected according to the presentation to be used. ..

Regarding the presentation device for giving a presentation using a scenario as described above, for example, Japanese Patent Laid-Open No. 62-152076 controls the presentation of display information to display means in accordance with the control information on the display. A presentation system is disclosed.

[0007]

As described above, generally, when a presentation is performed by a presentation device, the images to be used are recorded in the device, and the reproduction order of the images, the type of special effect to be used, and the special effect thereof are also recorded. It is necessary to register in advance the scenario in which the execution position in the presentation is recorded in the device. Therefore, even if the presentation execution procedure is changed, even if it is small, the scenario is rewritten and re-registered, or a completely new scenario is created.

On the other hand, as a form of presentation, in addition to the presentation in which the scenario is created in advance and various special effects are woven as described above, it is desired to give a presentation with a handy feeling like using a conventional OHP or a slide. There is also a request. Especially in the latter case, that is, when there is a case where a presentation is to be performed easily by omitting the procedure of creating and registering a scenario because there is no need for elaborate special effects, the scenario described above is required. With such a device,
I can't handle it easily.

Further, in response to a request to select and present from a large amount of past image data that has been created at any given time, a presentation device having a conventional configuration or an image is searched and displayed each time. This is not suitable for an image file device having such a configuration.

The present invention has been made in view of these problems, and an object thereof is, in addition to a mode in which a presentation is executed by a presentation device by creating a scenario (hereinafter referred to as a scenario execution mode), A mode in which a presentation is executed by simply selecting and registering a required image from the images recorded on the recording medium by a simple operation, saving the trouble of creating a scenario (hereinafter,
An image selection execution mode) is provided to provide a presentation device that can easily give a presentation.

[0011]

In order to solve the above-mentioned problems, the present invention provides a presentation device provided with an image storage means and a first display control means for reading and displaying an image from the image storage means. Second, displaying a list of image information of a plurality of images stored in the image storage means
Of the display control means and the image information displayed by the second display control means, the information selecting means for selecting an arbitrary number of arbitrary image information, and the image information selected by the information selecting means. The display control means displays the corresponding images according to the selected order by the first display control means.

[0012]

From the image information of a plurality of images stored in the image storage means displayed in a list by the second display control means, the information selection means selects only the image information used for display in the order of display. However, by displaying the images in the order selected by the display instructing means, the presentation can be executed without using special display control information.

This is the back key to instruct to return to.

The search by the search key 26 is an image search in the presentation unit at the time of presentation execution, while in the initial state of the device, all image data recorded in the optical disk device 8 is targeted. It is supposed to do a search.

First, the operation of the apparatus will be described with reference to FIGS. In this embodiment, it is assumed that the image data and the scenario necessary for executing the presentation are all recorded in advance on the optical disc device 8. When the power is turned on, the CPU 3 reads the system program from the program management unit 6 and stores it in the work memory 4, and the subsequent CP
The processing operation by U3 is performed on this work memory 4.

This allows the display 12
Displays a message prompting the user to select either the scenario execution mode or the screen selection execution mode, and waits for the input of a control command from the remote control transmitter 15.

In the following, the case where the scenario execution mode is selected will be described first, and then the case where the image selection execution mode will be selected will be described as the procedure of the description. By pressing the execution key 25 of the remote control transmitter 15, the user sends a control command to execute the presentation according to the scenario to the apparatus main body. This control command is received by the remote controller receiver 14 and transferred to the operation controller 2 via the system bus 1. The CPU 3 in the operation control unit 2 lists the scenario attribute data (file name, file size, recording position on the disc, etc.) registered in the optical disc device 8 and, via the interface unit 9, the scenario management unit 7 At the same time, the display control circuit 11 is instructed to display a list of scenario lists. As a result, a list of scenarios registered in the optical disk device 8 is displayed as a list on the display 12, and a cursor for assisting the user's selection operation is also displayed at the same time. The user sets the cursor to the target scenario name with the cursor keys of the remote control transmitter 15, and then issues an execution instruction with the execution key 25. Based on the attribute data stored in the scenario management unit 7, the CPU 3 reads the selected scenario file from the optical disk device 8 to the work memory 4 via the interface unit 9, and the scenario file is designated as the first screen. The image data that has been read is read from the optical disk device 8. The image data is recorded together with the attribute information as shown in FIG. 3 and a combination of the reduced image and the original image used for image selection and search. If compression is designated as the attribute information of the first screen, the compressed data is sent to the image compression / expansion processing circuit 13 to be expanded, and if it is non-compressed data, it is sent directly to the display memory 10. .. The image data stored in the display memory 10 is converted into a video signal by a control signal of the display control circuit 11 and displayed as an image on the display 12. At this time, if a special effect is designated in the execution procedure, this is also executed by the display control circuit 11.

The progress of the presentation (switching of the display screen) is repeated by the above-mentioned image data read / display operation in response to the forward / backward command normally issued by the user using the forward / backward keys 27/28 of the remote control transmitter 15. This is performed by switching the display image. When the scenario has reached the end, the scenario presentation ends.

Next, in addition to FIG. 1 and FIG. 2, an image selection execution mode for executing a presentation by selecting a plurality of images recorded in the optical disk device 8 without using a scenario 4, FIG. 5, FIG. 6 and FIG. FIG. 4 is a display example of the multi-screen when image selection is started, and FIG. 5 is a display example of the multi-screen during execution of image selection. Note that the same components in FIG. 4 and FIG. In FIG. 4, 41 is a display screen of the display, 42 is an image selection frame for assisting the user's image selection at the time of image selection, 43a, 43b, 43c, 43.
.., 43p are reduced images read from the optical disk device 8, respectively, and 51a, 51b, 5 in FIG.
Reference numeral 1c is a numeral for indicating to the user the selected image and the selected order of the images. 6 is a flowchart showing the operation flow of the apparatus after the user selects the image selection execution mode, and FIG. 7 is a flowchart of the operation flow performed following FIG. Mode selection such as scenario execution or image selection execution is performed by the same operation as in the case of scenario selection described above.

When the image selection execution mode is selected, it is first determined whether or not an image used for the presentation is already registered in the image information management section 5 (process 1). If the image is registered. Prompts the user to select whether to perform a presentation using registered images or to select a new image (processes 2 to 4). When the presentation execution is selected, according to the image information of each image recorded in the image information management unit 5 and the order thereof, in the same procedure as the description of the scenario execution described above.
The presentation is executed (process 5).

When an image selection instruction is input, the reduced images of the original image are sequentially read from the optical disk device 8 and written in the display memory 10 for multi-screen display, and at the same time, for assisting the user in image selection. The image selection frame (42 in FIG. 4) is displayed (process 6). If the image is not registered in the image information management unit 5 by the process 1, the process directly goes to the process 6.

Next, it is judged whether or not there is a next multi-screen display instruction (by the forward key 27 of the remote controller transmitter 15) from the user (process 7), and if there is no next step (FIG. 7). To the first processing step of the flow shown in FIG. On the other hand, when the next multi-screen display is instructed, it is determined whether or not there is image data that could not be displayed on the first multi-screen in the optical disk device 8 (process 8).
If there is not, an error message to that effect is displayed (process 9), and the process proceeds to the next step (the first process step of the flow shown in FIG. 7). If there is, the remaining reduced image data is read out. Display it again as a multi-screen (Process 1
0) Return to processing 7.

Subsequently, as shown in FIG. 7, it is determined whether or not an instruction (by the cursor key 21 of the remote control transmitter 15) for changing the position of the image selection frame 42 displayed on the multi-screen is issued ( In the process 11), if the change is instructed, the image selection frame 42 is displayed again at the instructed position (process 12). If the change is not instructed, it is determined whether an instruction to confirm the selection (by the registration key 22 of the remote control transmitter 15) or an instruction to cancel the selection (also by the release key 23) is issued (processes 13 and 14), When either instruction is issued, the image information of the image of which the selection is confirmed (FIG. 3) is stored in the image information management unit 5 or the image information of the image of which the selection is deselected is deleted from the image information management unit 5. (Processes 15 and 16).

The above processing is repeated until an image selection end instruction (by the decision key 24 of the remote controller transmitter 15) is issued (processing 17). When the images are selected and confirmed, as shown in FIG. 5, the numbers are displayed on the multi-screens in the order in which the images are selected and confirmed, for the convenience of the user. When the selection is deselected, the numbers displayed on the image are erased, and the numbers are re-displayed by closing the order with the remaining images.

When the image selection end instruction is issued, the reduced images of the selected images are displayed on the multi-screen in the selected order to prompt the user's confirmation (process 18). After that, the process returns to the process 1 of FIG. Therefore, the user can re-register the image if necessary. In this way, the user can easily give a presentation simply by selecting and registering a desired image from the numerous image data in the order in which he or she wants to display it.

Image retrieval is possible during execution of the scenario execution mode and the image selection execution mode described above and in the initial state of the apparatus. The images to be searched are all the images recorded in the optical disk device 8 in the search in the initial state, and during execution of the scenario execution mode and the image selection execution mode, the images in the presentation unit being executed. Is. The image search is started by pressing the search key 26 of the remote control transmitter 15 in each state of the above device.
The operation of selecting an image to be searched is the same as the image selection operation in the image selection execution mode described above, and screen selection is performed by multi-screen display. However, at the time of image search, when one image is selected and confirmed, the search operation of the optical disk device 8 is immediately started, and the selected image is displayed instead of the multi-screen for search.

As described above, in the present embodiment, in addition to normal scenario execution, presentation can be performed using registered images by simple image selection by multi-screen display. So that the user can select one,
A presentation using a special effect based on a scenario and a simple presentation can be selectively used depending on the occasion, and the effect is great.

Next, another embodiment of the presentation device to which the present invention is applied will be described. In this example,
The configuration of FIG. 6 used in the first embodiment is changed (FIG. 8). The drawings and the reference numerals used in the first embodiment are applied to the other overlapping portions as they are. Also in this embodiment, the user can select between the scenario execution mode and the image selection execution mode, which is the same as in the first embodiment, and a description thereof will be omitted. The feature of this embodiment is that after an image used in a presentation is registered in the image selection execution mode, scenario data is automatically generated from this registration data.

The operation at this time will be described below with reference to FIG. In FIG. 8, the same processes as those in FIG. 6 are designated by the same reference numerals. After the initial operation of the apparatus, the operation from the selection of execution of image selection to processing 4 in FIG. 6 is the same as that in the first embodiment. When the execution of the presentation is instructed by the process 4, scenario data describing the display order of the images is generated from the image information registered in the image information management unit 5 (process 81), and the scenario data is reused. The user is allowed to select whether or not to register (process 82). If not registered, the presentation is executed as it is (process 83). If there is an instruction to register, the generated scenario data is used. After recording on the optical disk device 8 (process 84), a presentation is executed (process 83).

To generate this scenario data, the CPU 3 loads the scenario data generation program stored in the program management unit 6 into the work memory 4 and registers the image information registered in the image information management unit 5 therewith. Convert and edit so that the order is maintained. The scenario data generated by the above operation is automatically attached with an identification code (for example, the generated date or time) so that the scenario data can be identified later when recorded on the optical disk device 8. The scenario data thus generated in a simple manner can be reused by newly adding reproduction control information such as a special effect using a unit (not shown) as needed.

As described above, in the present embodiment, since the registration data generated by image selection is converted into scenario data, in addition to the simple presentation by a simple operation, the data generated thereby can be stored. It can be reused as a scenario later, and the efficiency of scenario editing is also improved.

In the above two embodiments, the image selection is performed by the multi-screen display, but the image selection may be performed by another method. Although FIGS. 4 and 5 are given as display examples of this multi-screen, the number of reduced images to be displayed is not limited to this, and may be more than this as long as the original image can be recognized. May be less.
