Abstract

The present invention provides a presentation system, a display device, and a program which realize a smoother presentation performance in case where information a presenter wishes to refer to is displayed in a terminal but not in a display device. The presentation system of the present invention is structured, for instance, by connecting a PC 100 and a projector 200 via a LAN 50. A display unit of the PC 100 can be set up to display information including, for example, explanatory notes, but when making the projector 200 display an image, the information will not be displayed by executing a data modification which makes the information invisible. The information such as the explanatory notes may be placed at an arbitrary location on the display unit 102 and this enables a smoother presentation performance.

Claims

1. A presentation system comprising a display device and a terminal, the display device includes

a data obtaining unit for obtaining a file containing slide data which indicates a first slide image;

a data modifying unit for modifying the slide data to make one or more parts of the first slide image invisible;

a first display unit; and

a first display image setting unit for having the first display unit display a second slide image based on the modified slide data, the second slide image being a slide image in which one or more parts of the first slide image are invisible; and

the terminal includes

a second display unit; and

a second display image setting unit for having the second display unit display the first slide image.

2. The presentation system of claim 1,

wherein the terminal further includes

a transmission unit for transmitting the file containing the slide data to the display device,

wherein the data obtaining unit obtains the file by receiving the file transmitted by the transmission unit.

3. The presentation system of claim 2,

wherein the terminal further includes

an editing unit for editing the slide data in accordance with an input from outside.

4. The presentation system of claim 1,

wherein the part which is made invisible by the data modifying unit is a part of text put in the first slide image by utilizing functions of presentation software.

5. The presentation system of claim 1,

wherein the part which is made invisible by the data modifying unit is a part of text put in a textbox which is embedded in the first slide image.

6. The presentation system of claim 1,

wherein the display device further includes

a modification condition setting unit for receiving settings regarding (a) a method of modification to be executed by the data modifying unit, and/or (b) conditions to be satisfied by parts of data to be modified.

7. A presentation system comprising a display device and a terminal, the display device includes

a data obtaining unit for obtaining the file containing slide data which indicates the first slide image, the first slide image including one or more invisible parts;

a first display unit;

a first display image setting unit for making the first display unit display the first slide image, based on the slide data;

data modifying unit for modifying the slide data to make the invisible parts of the first slide image visible;

an image expansion unit for generating image data of the second slide image from slide data modified by the data modifying unit;

an image data compression unit for compressing the image data of the second slide image; and

a transmission unit for transmitting the image data compressed by the image data compression unit to the terminal; and

the terminal includes

a reception unit for receiving the image data transmitted by the transmission unit;

an image data decompression unit for decompressing the image data received by the reception unit;

a second display unit; and

a second display image setting unit for making the second display unit display the second slide image, based on the decompressed image data.

8. The presentation system of claim 7,

wherein the display device further includes

a modification condition setting unit for receiving settings regarding (a) a method of modification to be executed by the data modifying unit, and/or (b) conditions to be satisfied by parts of data to be modified.

9. A display device comprising:

a data obtaining unit for obtaining a file containing a first slide data which indicates a first slide image;

a data modifying unit for executing at least one of the following processes. (a) Creates the second slide data which indicates the second slide image by modifying the first slide data, the second slide image being an image which has one or more parts of the first slide image invisible, (b) creates a second slide data which indicates a second slide image by modifying the first slide data, the second slide image being an image of one or more invisible parts of the first image modified to be visible;

a display unit; and

a display image setting unit for making the display unit display a slide image based on the first slide data or the second slide data, wherein the displayed image is (a) the second slide image if the second slide image is a slide image which has one or more parts of the first slide image part invisible, and (b) the first slide image if the second slide image is an image of one or more invisible parts modified to be visible.

10. The display device of claim 9, wherein the data obtaining unit includes

a reception unit for receiving the file.

11. The display device of claim 9 further comprising:

an image expansion unit for generating image data of a first slide image or a second slide image from a first slide data or a second slide data, wherein the slide image for which the image data is generated is the first slide image if the second slide image is an image of one or more parts of the first slide image made invisible, and is the second slide image if the second image is an image of one or more invisible parts of the first image modified to be visible;

an image data compression unit for compressing the image data which is generated by the image expansion unit; and

a transmission unit for transmitting the compressed image data.

12. The display device of claim 9,

wherein the part which is made invisible or visible by the data modifying unit is a part of text put in a slide image by utilizing functions of presentation software.

13. The display device of claim 9,

wherein the part which is made invisible or visible by the data modifying unit is a part of text put in a textbox which is embedded in the slide image.

14. The display device of claim 9,

wherein the data modifying unit includes

a deletion unit for deleting a part which corresponds to an invisible part in the second slide image from the first slide data.

15. The display device of claim 9,

wherein the data modifying unit includes

a color modifying unit for modifying the color setting of a part which corresponds to an invisible or a visible part in the second slide image in contrast to the first slide data.

16. The display device of claim 9,

wherein the data modifying unit includes

a background color modification unit for modifying the background color setting in contrast to the first slide data.

17. The display device of claim 9 includes

a modification condition setting unit for receiving settings regarding (a) a method of modification to be executed by the data modifying unit, and/or (b) conditions to be satisfied by parts for a modification of the parts to take place.

18. The display device of claim 9,

wherein the display control unit includes

a switching unit for switching whether to make the display unit display the first or the second slide image.

20. The program of claim 19,

wherein the data modifying step modifies the contents of the first slide data into the second slide data by deleting one or more parts contained in the first slide data.

21. The program of claim 19,

wherein the data modifying step modifies the contents of the first slide data into the second slide data by modifying parameters set in the first slide data.

19. A program which is operable by a processor provided in a display device includes

a file obtaining step for obtaining a file including a first slide data which indicates a first slide image;

a data modifying step for executing at least one of the following processes, (a) Creates a second slide data which indicates the second slide image by modifying the first slide data, wherein the second slide image is an image which has one or more parts of the first slide image invisible (b) creates a second slide data which indicates a second slide image by modifying the first slide data, wherein the second image is an image of the first slide image which has the invisible parts modified to be visible.
