In such a presentation, an image on a personal computer screen is directly projected and displayed on a display device such as a liquid crystal projector using dedicated software.

[0004]

By using the above-mentioned presentation-dedicated software, a presentation with good appearance can be executed, but it takes time and effort to create materials, and the user is usually used to perform informal meetings. We want to easily display the data using word processing software or spreadsheet software without any hassle.

[0005] In addition, as a presenter, there is a case where it is desired to flexibly change a screen to be presented according to story development. Can not be confirmed,
There is no choice but to sufficiently store the contents of the image at hand. This poses a risk, if not impossible, of presenting an incorrect image and reducing the persuasiveness of the entire presentation.

[0006] Furthermore, the image quality is also an important point of the presentation, and it is essential to display a clear image as well as the content. In particular, in the description of clothes and the like, accurate color reproduction is regarded as important, and the color must not be different every time the display device changes.

In order to solve the above-mentioned problem, a liquid crystal projector (ELP-3300) manufactured by Epson provides a still function of an input image by using a memory function in the apparatus. There is no proposal for a presentation method that utilizes the concept.

An object of the present invention is to provide a display device and a display method which can solve such a problem, can easily and easily display a desired image without error, and have excellent color reproducibility.

[0009]

To achieve the above object, the present invention provides a memory function and a color conversion function in a display device based on a control signal from an information processing device and an image from the display processing device. A signal is interlocked and controlled, and a cutout display or a slideshow display of a specific area from the screen is performed.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of a display device and a display method according to the present invention, wherein 1 is an information processing device, 2 is a display device, 3 is AD conversion means, 4 is storage means, Reference numeral 5 denotes a DA converter, 6 denotes a controller, 7 denotes a microcomputer, and 8 denotes a display.

A feature of this embodiment is that only a specific portion of an image displayed on a screen of an information processing apparatus is cut out and displayed, so that only a desired portion can be shown to an audience. is there.

In FIG. 1, a display device 2 includes an A / D conversion means 3, a storage means 4, a D / A conversion means 5, a control means 6 for controlling the A / D conversion means 3, the storage means 4 and the D / A conversion means 5, and an information processing apparatus. 1 and a microcomputer 7 for exchanging control information with the control means 6 and transmitting the control information to the control means 6, and a display means 8. The display means 8 is a display device such as a liquid crystal display device, a plasma display device, or a CRT device.

The information processing apparatus 1 is, for example, a personal computer, and outputs a video signal and a control signal. This control signal is a specific area instruction signal for instructing to display a specific area of the video signal output from the information processing device 1.

FIG. 3 is a diagram showing a configuration in which a liquid crystal projector is used as the display device 2, wherein 101 is a personal computer as the information processing device 1, 102 is a liquid crystal projector, and 103 is a screen.

In FIG. 1, a liquid crystal projector 102 displays a color image on a screen 103 in response to a color video signal from a personal computer 101. In this case, of the image displayed on the screen of the personal computer 101, a portion surrounded by a black frame is a color image projected on the screen 103 by the liquid crystal projector 102.

FIG. 4 is a diagram showing an example of an image displayed on the screen of the personal computer 101 in FIG. 3, and shows an example of a screen of "Windows (registered trademark)" as basic software of the personal computer.

In the figure, for example, in the control window, the x and y coordinates of the start point (upper left corner) and the x and y of the end point (lower right corner) of the area designation wire frame indicated by a black frame are shown.
The coordinates are displayed, and information indicating whether the output is continuous or single-shot is displayed as the address output method. Continuous output is
When the button is pressed (in a personal computer, click by mouse operation), the start and end addresses are output continuously, and when the single output button is pressed, the output is started only when the start and end addresses are pressed. Things. In this manner, in the screen of the personal computer 101, the address of the area designation wire frame is
02.

Next, the processing operation in the liquid crystal projector will be described with reference to FIG.

The video output from the information processing apparatus 1 is supplied to the AD conversion means 3, converted into digital video data, and then written into the storage means 4. This storage means 4
May be, for example, a frame memory. The video data written in the storage means 4 is read under the control of the control means 6, converted into an analog video signal by the DA conversion means 5, and then supplied to the display means 8 for image display. .

The output data of the storage means 4 may be multi-phase output in accordance with the specifications of the display means 8, or the DA conversion means 5 may be omitted, and the output data of the display means 8 may be omitted.

It is needless to say that, when the video signal is a signal of three primary colors of R, G, and B, three systems are provided for each of them.

After the start point address and the end point address of the area designation wire frame are received by the microcomputer 7, the read range of the storage means 4 is set to the range determined by the start point and the end point via the control means 6, for example. In this way, as shown in FIG. 3, only the image of the specific area surrounded by the area designation wire frame on the screen of the personal computer 101 is projected and displayed on the screen 103.

When the continuous output is designated and the designated area wire frame is moved by the mouse, it goes without saying that the image area projected and displayed on the screen 103 changes in real time. As a result, an area to be shown on the screen of the personal computer 101 can be changed to the screen 103 as desired.
Can be displayed.

Also, in FIG.
In the case where the storage means 4 is provided, the control method of the control means 6 only needs to be changed in accordance with the storage means 4, so that there are almost no additional components, and this can be realized at low cost.

FIG. 2 is a diagram showing a specific example of the format of the transfer data of the specific area instruction signal in FIG.

In the figure, a specific area instruction signal is composed of a specified area display command and a start point and end point address. It is needless to say that the data to be transferred may be not only the address of the start point and the end point of the designated area wire frame but also data indicating the start point address and the width of the designated area wire frame. As a method of transmitting a control signal between the information processing device 1 and the display device 2, for example, V

The feature of this embodiment is that the operator selects and shows only one of the images to be listened to while listening to a list of a plurality of images to be displayed and grasping the whole. It is in. The overall basic configuration is the same as that shown in FIG. 1. In FIG. 5, a still image is displayed by utilizing the data holding function of the storage means 4 (FIG. 1).

First, referring to FIG.
A list of a plurality of index images (images to be displayed smaller) is displayed on one screen. Clicking on the desired image of these index images with the mouse,
As shown in FIG. 5B, the image is enlarged and displayed on the entire screen of the personal computer 201. Of course, the image data is also supplied to the display device 202, written and read out by the storage means 4, and projected and displayed on the screen 203. Here, when a phrase command is given from the personal computer 201 to the display device 202, the data update in the storage means 4 is prohibited at that moment, the image data stored at that time remains as it is, and the image is displayed on the screen 203. ing. Then, as shown in FIG.
The screen 01 returns to the state where the original index image is displayed. The display device 202 retains the data of the image shown in FIG. 5B in the storage means 4 as it is in response to the freeze instruction, and the image is continuously displayed on the screen 203 as it is. That is, only the desired image is displayed on the screen 2
03 will be displayed.

Thus, the presenter can show only the desired screen to the audience and can see the list screen, so that the development of the talk can be changed flexibly according to the audience's reaction, and a convincing presentation can be made. Can be realized smoothly.

It is needless to say that the personal computer 201 needs software for the above operation in advance, and it is necessary to register image data.

Is changed to new image information, that is, image information to be currently selected and displayed. It waits for the time required for this change, for example, a time equal to or longer than one vertical cycle (step 2004), and then executes a freeze (step 2005). When the freeze is completed, the completion response information is sent to the personal computer 201 (step 2).
006).

Thus, the personal computer 201 fetches the freeze completion response (step 1005).
After confirming the completion of the freeze (step 100)
6) Display the index image again (step 1)
007), a list of a plurality of images is displayed on the screen. The above flowchart is repeated.

Here, the processing in steps 1003 to 1007 is instantaneous, and although the screen change is instantaneously recognized by the presenter, the audience is not seen and there is no influence on the presentation execution.

In this way, the operator can display only one image at a time of listening while grasping the whole image by displaying a plurality of images to be displayed. Perform compelling presentations.

FIG. 7 is a diagram showing a specific example of a list image display on the screen of the personal computer 201.
The index image is displayed in the frame of.

Although the simple switching has been described above, a so-called switching effect can be realized by continuously inserting a switching effect image such as a fade or a dissolve between switching between images. Of course you can.

FIG. 8 is a block diagram showing a third embodiment of the display device and the display method according to the present invention. Reference numeral 10 denotes color conversion means, and portions corresponding to those in FIG. The description of the operation will be omitted.

In this figure, the feature of this embodiment is that a color conversion means 10 is provided between the storage means 4 and the DA conversion means 5, and the color conversion means 10 performs optimal color adjustment according to the image content. It is possible to provide a video with a good impression for listening.

The A / D conversion means 3 and the storage means 4, D
A conversion means 5 is provided for each of the R, G, and B primary color signals, and the color conversion means 10 also performs a conversion process for each of the R, G, and B primary color signals, so that the hue, saturation, and brightness have desired values. So that The color conversion means 10 has an LUT (Look Up Table) function, and corrects the gamma characteristic of the display means 8 to realize a linear gradation characteristic. Note that the color conversion unit 10 may of course be provided in a stage preceding the storage unit 4.

FIG. 9 shows a specific example of the purpose of conversion of a display image by the color conversion means 10, and FIG. 10 shows the conversion characteristics. FIG. 10 particularly shows an example of the gradation characteristic.

In FIGS. 9 and 10, when the display image is mainly composed of characters or graphics, since the image signal itself often has a saturation level such as a maximum value or a minimum value, the saturation display is emphasized and the LUT is emphasized. The input / output characteristics are set to the characteristics a shown in FIG. 10 so that a clear video display can be performed. On the other hand, when the display image is mainly composed of a natural image, since there are many signals at the halftone level, importance is placed on the gradation display, and the LUT input / output characteristic is changed to the characteristic b shown in FIG. To be able to do it.
For an image in which characters, graphics, and a natural image are mixed, the LUT input / output characteristic is set to a characteristic c shown in FIG. 10 so that an average display in the above two cases can be performed.

Further, even in a natural image, particularly when there are many human skins, the hue and the saturation are changed so that a beautiful skin color can be expressed.

The above set values may be set, for example, as shown in FIG. FIG. 11 is a close-up of image No. 1 in FIG. For example, if the image shown in FIG. 11 is a natural image, a control window for setting the LUT is provided above the index image, and “character / graphic”, “natural image” and “character / graphic + natural image” are provided therein. Are set so that the user can set one of them according to the image content to be displayed. FIG. 11 shows a state where a natural image is selected.

In this way, a natural image is selected and, for example, in the same manner as in the second embodiment shown in FIG.
At the time of full-screen display, data for color conversion may be sent to the display device 2 together with a freeze command. Of course, if there is a large amount of data for color conversion, the data may be registered in the color conversion means 10 or the like in advance, and the information processing device 1 may send only a color conversion execution command for a natural image.

The third embodiment is similar to that of FIGS.
The same can be realized with the specific area display of the first embodiment described above.

As described above, the color conversion means 10 can perform optimal color adjustment in accordance with the image content, and can provide a video with a good impression for listening.

FIG. 12 is a block diagram showing a fourth embodiment of the display device and the display method according to the present invention, wherein 11 is a monitor, 12 is a ROM, 301 is a personal computer, and FIG.
The same reference numerals are given to the portions corresponding to and the duplicate description will be omitted.

In the figure, the feature of this embodiment is that the image display state displayed on the display device 2 can be confirmed in advance.

The configuration of the fourth embodiment is basically the same as that of the third embodiment shown in FIG. 8, except that a ROM 12 having the display characteristics of the display device 2 is provided. . The ROM 12 stores data such as the gradation characteristics and the color reproduction range of the display unit 8. This data is sent to the personal computer 301, and when the data is displayed on the monitor 11 in advance, a display reflecting the value of the data is performed. Of course, the data conversion calculation taking into account the display characteristics of the monitor 11 is performed by the personal computer 301.

FIG. 13 shows a specific example of a display image on the monitor 11 at the time of this preliminary display. This is almost the same as that shown in FIG. 11, except that an item of “custom” is provided. When this item is selected, for example, the hue, saturation, and lightness as shown in FIG. The adjustment bar is displayed. The value of the adjustment bar, that is, the level display is changed by a mouse click operation, and the image data displayed in advance is converted according to the changed value and displayed again. Thereby, the state of the image displayed on the display device 2 can be checked in advance, and the user can adjust the state to a desired state.

In FIG. 15, the control window includes screen settings in addition to the LUT settings. In the case of a projection-type display device such as a liquid crystal projector, the screen may be various, such as an OHP screen, a whiteboard, or paper, in addition to a dedicated product, depending on the convenience of the user. In a projection display device, such a function is effective because color reproducibility differs depending on the type of screen.

As described above, the image display state can be checked in advance, the deviation between the originally assumed color and the color displayed in the actual production can be eliminated, and the deviation of the color can be corrected before the actual production. This greatly simplifies repetitive tasks such as checking on the screen for use, and can strongly support rehearsals prior to the presentation.

FIG. 16 is a block diagram showing a fifth embodiment of the display device and the display method according to the present invention, wherein 21 is data reading means, 22 is drawing processing means, 23 is an information storage medium, and 24 is a switch. The same reference numerals are given to portions corresponding to the above-described drawings.

In this figure, in this embodiment, a display device 2 is provided with a data reading means 21 and a drawing processing means 22,
By connecting the information storage medium 23, image information from the information storage medium 23 can also be displayed. Therefore, even without the information processing device 1,
Since an image can be displayed on the information storage medium 23, labor for transporting the information processing apparatus 1 is unnecessary.

In particular, the feature of the fifth embodiment resides in that the storage means 4 is used as the storage means for the drawing processing means 22, and this is shared with the output of the AD conversion means 3.
Thereby, cost reduction can be realized.

Conventionally, as shown in FIG. 17, the drawing processing means 22 is provided with a dedicated storage means 4 ', and the image information read therefrom is converted into an analog video signal by the dedicated DA conversion means 26. The data is switched by the switch 25 and input to the storage means 4, and two storage means having a capacity necessary for displaying on the display means 8 are required.

On the other hand, in the fifth embodiment, the storage means 4 is used for both the video signal from the information processing apparatus 1 and the video signal from the information storage medium. However, there is an advantage that cost can be reduced.

Next, the operation of the fifth embodiment will be described.

First, the information storage medium 23 storing data such as image information is inserted into the data reading means 21.
At this time, it is preferable that the switch 24 automatically switches to the drawing processing unit 22 side. The data of the inserted information storage medium 23 is read based on, for example, a command from the microcomputer 7, and the read data is written to the storage unit 4 via the drawing processing unit 22 and the switch 24. The writing control of the storage means 4 is performed by the control means 6. The control means 6 operates according to a timing signal or the like from the drawing processing means 22.

[0064]

As described above, according to the present invention,
Based on a control signal from the information processing device, a memory function and a color conversion function in the display device are controlled in conjunction with an image signal from the information processing device, and a cutout display of a specific area of an image or a still image display such as a slide show is performed. Can be performed with clean image quality according to the image content, and a convincing presentation can be realized with a relatively simple configuration.

Further, according to the present invention, the pre-display function based on the display characteristics of the display device makes it possible to check in advance the actual image display state, and strongly supports the rehearsal prior to the execution of the presentation. it can.
