Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a painting viewing system, and more particularly to a painting viewing system that presents a still image including characters to a viewer together with audio using a high-vision display device.

[Conventional technology]

With the practical use of HDTV, systems for displaying still images in HDTV have been developed. For example, in a museum or the like, an attempt has been made to introduce a system for displaying a still image of an image on a high-vision display device and presenting it to a viewer. Since high-definition images can be displayed with very high resolution and high definition, it is possible to appreciate a realistic painting by using a display device. Such a system has the advantages that paintings that cannot be displayed normally can be viewed on the display device, and that a description of each painting can be displayed together with a still image of the painting.

There are mainly two methods for displaying characters such as explanatory text on a display device. The second method is a method of using a scanner to capture characters as image data from under a printing plate or the like and displaying the characters as an image. The second method is a method in which character data is generated by a computer and characters are displayed based on the character data.

[Problems to be solved by the invention]

However, both of the above two methods have problems. The first method has the advantage that the characters under the printing plate can be taken as they are, so that the font and the size of the characters can be freely selected and beautiful characters can be displayed. There is a problem that it takes time. In particular, when correcting characters, it is necessary to repeat the operation from the creation of the printing plate, which is very inconvenient.

On the other hand, in the second method, since character data is created by a computer, input and correction of characters are very easy, and workability is excellent, but the quality of displayed characters is poor. is there. That is, characters suitable for the display device used cannot be displayed. For example, when displaying characters together with a still image on a display device, a conventional system uses a CD-ROM.
A character string created by a computer is superimposed on a still image read out from a computer or the like, and this is displayed on a display device. In this case, if still image data having a resolution suitable for the display device is prepared in a CD-ROM or the like, the displayed still image is suitable for the display device. However, the characters superimposed and displayed are characters originally prepared in the computer, and thus are not necessarily of high quality suitable for the display device. For example, when a display device for high definition is used as the display device, a still image having a resolution (1920 × 1035 pixels) suitable for high definition may be prepared in the CD-ROM. However, as for characters, as a character font suitable for HDTV, for example, 42 ×
While a character font of 42 pixels is used, a character font prepared in a general personal computer is 16 × 16 pixels. Therefore, the low-resolution computer character font is subjected to interpolation processing to display the character on a high-vision display device. With such a method, it is not possible to display high-definition characters that make full use of the performance of Hi-Vision. For this reason, there has been a problem that characters are harder to see than a still image.

Therefore, an object of the present invention is to provide a picture appreciation system capable of displaying high-quality characters suitable for a display device to be used with good workability.

[Means for solving the problem]

According to a first aspect of the present invention, in a painting viewing system, a display device for displaying a still image to a viewer, an input device for inputting an instruction from the viewer, and still image data of a painting to be viewed are stored.

(Operation)

In the painting viewing system according to the present invention, instructions from the viewer are input to the computer via the input device. The computer issues a command to the still image reproducing device and the audio reproducing device to search for a still image and a sound desired by the viewer based on the instruction of the viewer. In addition, the computer, based on the instructions of the viewer,
Search for text data indicating a character string to be displayed. Then, font data of each character corresponding to the text data is extracted, and the extracted font data is developed on a bitmap plane of an image developing unit. The expanded font data is not a computer font data but a display device font data. Therefore, characters suitable for the display device can be displayed.

〔Example〕

Hereinafter, the present invention will be described based on the illustrated embodiments.
FIG. 1 is a block diagram showing a basic configuration of a picture appreciation system according to one embodiment of the present invention. This system is, more specifically, a device for presenting a still image of a painting and its setting to a viewer using a display device for high-definition, and can be installed and used in a museum or the like. System.

The configuration of this system is as follows. First, a computer 10 is prepared for controlling the entire system. In this embodiment, a personal computer is used. The computer 10 is connected to a hard disk 11 and a font memory 12 as external storage devices, and further includes a monitor 13 and a printer 14 as peripheral devices.
Is connected. Further, the computer 10 has a function of controlling the still image reproducing device 20 and the audio reproducing device 30. The still image reproducing device 20 has a function of searching image data in the CD-ROM 21 and reproducing a desired still image. Further, the audio reproducing device 30 has a function of searching audio data in the CD-ROM 31 and reproducing a desired audio. The computer 10 also has a function of outputting predetermined font data and layout position data for the font to the image developing unit 40. The image developing unit 40 has a bitmap plane corresponding to the pixel array of the display screen for high vision, and the font data output from the computer is developed on this bitmap plane based on the data indicating the allocation position. The image data thus expanded is output as an RGB signal, but is converted into Y, Pb, and Pr signals in the signal converter 50. On the other hand, the still image reproducing device 2
0 outputs a still image in the form of Y, Pb, Pr signals. The image superimposing section 60 superimposes the signal supplied from the still image reproducing apparatus 20 and the signal supplied from the signal converting section 50, and supplies this to the high-vision display device 70. Thus, on the display screen of the high-vision display device 70, the character string generated by the computer 10 is displayed so as to overlap the still image reproduced by the still image reproducing device 20. The viewer can use the mouse 80 connected to the computer 10 to give an instruction to display a desired still image. The sound reproduced by the sound reproducing device 30 is transmitted to the viewer by the speaker 90.

As described above, this system is configured so that it can be installed in a museum or the like. Therefore, the high-vision display device 70 and the speaker 90 are mounted on a wall surface in a building or the like. The mouse 80 is installed near the display device 70 so that the viewer can operate the mouse 80 while looking at the display screen of the display device 70. The devices that the viewer directly contacts are the high-vision display device 70, the mouse 80, and the speaker 90.

The hard disk 11 stores application software, text data, and high-definition fonts. The application software is basic software for operating the computer 10,
The text data is data on a character string to be displayed over a still image. The HDTV font is font data suitable for displaying characters on the HDTV display device 70, and is used after being loaded into the font memory 12 as described later. In this embodiment, data of still images for a large number of paintings are stored in the CD-ROM 21 and the CD-ROM 3
The voice data of the narration for explaining each painting is stored in 1.

The operation of this system is as follows. Fig. 2
9 is a flowchart showing a processing procedure of a computer 10 operating according to application software. First, in step S1, a high-vision font is loaded. This is an operation of loading high-definition font data in the hard disk into the font memory 12. As will be described later, the computer 10 frequently accesses the HDTV font. Therefore, the access speed can be increased by loading the font data from the hard disk 11 into the font memory 12 (RAM in this embodiment). Further, the font set in the hard disk 11 can be easily replaced with another one as needed. In the system of this embodiment, while the font prepared inside the computer 10 is composed of 16 × 16 pixels,
A high-definition font is composed of 42 × 42 pixels. That is, the font loaded into the font memory 12 is optimal for display on the high-vision display device 70, and enables high-definition character display. Even for the same character, a separate font is prepared for each of a plurality of typefaces, and a separate font is prepared for each character size. For example, for one kanji character “Yama”, two types of fonts, Mincho and Gothic, are prepared, and two types of fonts, full-width and half-width, are prepared. Will be prepared separately.

Subsequently, in step S2, a menu is displayed. This menu is displayed on the screen of the high-vision display device 70 so as to allow the viewer to input an instruction as to which painting to view.
The viewer operates the mouse 80 to give a desired instruction to the menu display. The instruction input in step S3 is the instruction input from the viewer. By this instruction input, the picture that the viewer desires to view is specified. Upon receiving the instruction input, the computer 10 searches for text data, still image data, and audio data corresponding to the specified painting in step S4. Actually, a necessary search is performed while referring to a directory in the application software. In the system of this embodiment, the computer 10 itself searches for text data. However, the search for still image data is performed by providing a necessary directory to the still image reproducing device 20, and the search for audio data is performed for the audio reproducing device 30. By giving the necessary directories. When the search is completed, in step S5, the searched data is output. Thus, the viewer can view the painting designated by the viewer on the screen of the high-vision display device 70. At this time, the explanation about this painting is displayed in a superimposed manner,
The narration of the explanation will be heard from the speaker 90. Subsequently, in order to appreciate another painting, if an input to that effect is made from the mouse 80, the procedure from step S2 is continued again via step S6.

The basic operation of the computer 10 has been described above. Next, a specific output method of each data in step S5 will be described. The method of outputting audio data is very simple. The sound reproducing device 30 receives a command from the computer 10, searches for desired sound data from the CD-ROM 31, and vibrates the speaker 90 based on the sound data. Thereby, the desired sound can be heard from the speaker.

The output method of still image data is almost the same. That is, the still image reproducing device 20 receives a command from the computer 10, searches the CD-ROM 21 for desired still image data, and outputs an image signal corresponding to the still image data. This image signal is a signal in the form of Y, Pb, and Pr. If the image signal is provided to the high-vision display device 70 as it is, a desired picture is displayed. However, in this system, characters are superimposed and displayed on the image of the painting by the image superimposing unit 60.

The method of outputting text data is the gist of the present invention, and is performed by the following special method. First, the structure of text data will be briefly described. In the system of the present embodiment, the text data is composed of a series of data as shown in FIG. In FIG. 3, each alphabet represents one byte of data, and every two bytes constitute one unit of data.
Of course, one unit of data does not necessarily need to be composed of two bytes, and may be composed of one byte. One unit of data is data indicating a function code or a character code. The character code is a code for specifying one character, for example, a JIS kanji code or the like is used. The function code is a code indicating an attribute of a subsequent character code, and is a code for specifying a typeface, a character size, a color, and the like. For example,
In the example shown in FIG. 3, the function code 1 performs a function of specifying a typeface, a character size, a color, and the like for three characters corresponding to the following character codes 1 to 3,
The function code 2 performs the same function for the character strings corresponding to the following character codes 4 to. When the computer 10 captures such text data,
The corresponding font data is extracted from the font memory 12 in consideration of the function code for each character code. For example, the function code 1 shown in FIG. 3 indicates a full-width Gothic character,
Assuming that the character code 1 indicates a kanji character “yama”, full-width Gothic font data as shown in the upper part of FIG. 4 is extracted for this character code 1. As described above, this font is a font of 42 × 42 pixels, and has a higher definition than the font which the computer 10 has.

In this way, the computer 10 extracts the corresponding font data for each character code constituting the text data and supplies the extracted font data to the image developing unit 40.
The image development unit 40 includes a display device 70 for high vision.
A bitmap plane corresponding to the pixel array on the display screen is prepared. FIG. 4 shows the bitmap plane 41. In this embodiment, a bitmap plane having a size of 1920 × 1024 pixels is prepared. Computer 10
Then, the font data is sequentially supplied to the image developing unit 40 for each character. At this time, data indicating the layout position of each character is also supplied together with the font data. The computer 10 calculates an assignment position of each character based on the text data. For example, once the layout position of the first character is determined, the next character is moved to the right by 42 pixels and becomes the layout position. If there is a character code indicating a line feed, the position of the left end of the next character moved downward by 42 pixels is the layout position. Image development unit 40
Converts the font data given from the computer 10 into
Similarly, it is expanded to the assigned position given by the computer 10. FIG. 4 shows an operation of expanding the font of the character "mountain" to the allocation position 42 on the bitmap plane 41.

Thus, the bitmap plane 41 in the image developing unit 40
When fonts for all necessary characters have been developed above, a signal indicating an image corresponding to this developed screen is displayed as RGB.
Is output in the format The signal converter 50 is a device that converts the RGB signals into Y, Pb, and Pr signals suitable for the display device 70. Finally, in the image superimposing unit 60, the Y, Pb, and Pr signals indicating the image of this character are
This is superimposed on the Y, Pb, and Pr signals indicating the still image output from 0, and a display in which the description is superimposed on the image of the painting is obtained on the high-vision display device 70.

With such a system configuration, it is possible to display high-definition characters together with high-definition painting images on the display screen of the high-vision display device 70. In the system of this embodiment, a monitor 13 is connected to the computer 10, and a character string displayed on the high-vision display device 70 can also be displayed on the monitor 13. The characters displayed on the monitor 13 are low-resolution fonts (16 × 16 pixels in this embodiment) built in the computer 10, but the display on this monitor is not intended to be presented to the viewer. Since it is used for the purpose of checking the operation of the system by the staff of the art museum, there is no particular problem. Further, this display content can be output to the printer 14 to obtain a hard copy.

As described above, the present invention has been described based on one embodiment illustrated in the drawings. However, the present invention is not limited to this embodiment, and can be implemented in various modes. For example, in the above-described embodiment, an example in which only one sheet is used as the bitmap plane 41 in the image developing unit 40 has been described. However, when displaying characters in color, it is necessary to prepare three planes of RGB. Good. It is also possible to use several more planes for displaying inverted characters and cursors.

In the above-described device, the instruction input from the viewer is performed by the mouse 80, but of course, another input device such as a keyboard may be used. In addition, font memory 12
Although an example using a memory connected to the outside of the computer 10 has been described above, a part of the internal memory of the computer 10 may be used as a font memory. The information storage media such as the hard disk 11 and the CD-ROMs 21 and 31 are not limited to these, and can be appropriately replaced with another information storage medium in design.

〔The invention's effect〕

As described above, according to the painting appreciation system according to the present invention, a character font for the display device is separately prepared,
Since necessary font data is extracted based on the text data, and the extracted font data is developed on a bitmap plane to display characters, high-quality characters suitable for the display device to be used are displayed with good workability. Will be able to
