Four).

[Problems to be solved by the invention]

Since the conventional image output device is configured as described above, when presenting at an international conference or the like, only data relating to the characters of the image data is changed to the same meaning and different characters (hereinafter referred to as words and phrases) as in the language of another country. There was a problem that the image data could not be changed and displayed, and image data had to be created individually. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-described problems, and has as its object to provide an image output apparatus capable of easily changing part or all of the characters of image data to a phrase specified from the outside and outputting the phrase. And

[Means for Solving the Problems]

An image output device according to the present invention provides character image data comprising a plurality of data sets in which image data, part or all of data relating to characters in the image data are expressed by words having the same meaning and different words, and A non-character image data which is data other than image data, a plurality of types of image data are stored in advance, and an image data holding unit which internally holds corresponding image data in response to an external instruction; An image data output unit for outputting data and a data set of a phrase specified from the outside.

[Operation]

An image output device according to the present invention has an image data holding unit that internally holds non-character image data and image data composed of character image data composed of a data set of a plurality of different phrases, and stores the non-character image data and external data. Since only the data set (as character image data) of the word and phrase designated from is read out, only the portion related to characters in the image data can be easily changed.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an image output device according to the present invention, which is an embodiment in which the image data is displayed as an output form of image data. Is omitted. In the figure, reference numeral 8 denotes a magnetic disk as a storage device for storing image data composed of drawing commands such as a plurality of straight lines, rectangles, circles, and character strings, and 9 denotes one of image data stored on the magnetic disk 8. Assume that the image data is a display instruction from the keyboard 1. Reference numeral 10 denotes a control unit that controls a read instruction or display instruction of the image data 9, 11 denotes an image data holding unit that internally holds the image data 9, and 12 denotes a read from the image data holding unit 11 according to an instruction of the control unit 10. An image data output unit that displays a data set of the specified non-character image data and the designated phrase as an image. FIG. 2 is a diagram showing the file structure of this image data. In the figure, 13 is a header portion of the file, 13a is the number of data sets, 13b is an offset value at the head of each data set, and 13c is each data set. , 14 is non-character image data, 15 is character image data, and the first data set 15
a, the second data set 15b. FIG. 3 is a diagram showing an example of the non-character image data 14 and the character image data 15 of the image data composed of the above-mentioned drawing commands, and shows a general drawing command in a notation unique to this embodiment. However, this does not particularly limit the programming language used. Next, the operation will be described with reference to the flowchart of FIG. First, a display instruction is given from the keyboard 1 by the user.
When the image file name and the display term phrase name (in this case, Japanese or English) are input (step ST
5), the control unit 10 reads the corresponding image data 9 from the magnetic disk 8 and causes the image data holding unit 11 to hold the image data 9 (step ST6). Here, the control unit 10 checks whether the language input and input is present in the image file as a data set (step ST7).
Alternatively, the drawing processing unit 4 is notified of the start address of the non-character image data 14 and the start address of the non-character image data 14 (step STb).
8) If not, the drawing processor 4 is notified of the start address of the first data set 15a in the image file and the start address of the non-character image data (step ST9). Drawing processing unit 4
Reads out the non-character image data 14 and the data set (15a or 15b) at the address specified by the control unit 10 from the image data holding unit 11 and develops them into figures and the like, and stores them in the frame buffer memory 5 as visual images. Drawing is performed (step ST10), and the CRT 6 repeatedly reads the contents of the frame buffer memory 5 in accordance with the scan frequency and displays the contents on the CRT (step ST11). FIG. 5 shows a display example by the image output device of the present invention. FIG. 5A shows a display in English, and FIG. 5B shows a display in Japanese. It is not necessary for the character image data to individually include all data relating to characters as a data set, and invariant portions (for example, scale numbers in FIGS. 5A and 5B) are regarded as non-character image data. Is also good. In the above embodiment, the CRT 6 is used as the display device, but a liquid phase display, a plasma display, a projection TV, or the like may be used. The drawing processing unit 4 develops the image data into a figure or the like and draws the image data in the frame buffer memory 5.
And the control unit 10 may have a drawing function. The drawing processing unit 4, the frame buffer memory 5, the CR
The display function of the image data output unit 12 composed of T6 may be controlled by developing and outputting graphics and the like in the print processing unit and printing by a printer, and transmitted to the outside via the communication processing unit and the communication line. Is also good. Further, although the keyboard 1 is used as the input means, an instruction from another computer may be used as the input means. In addition, the instruction of the phrase to be displayed is input from outside, but may be specified in advance. Further, although the magnetic disk 8 is used as the storage device, image data may be transferred from another device via a communication line. In the above embodiment, the type of the data set is language (Japanese and English), but may be words having different meanings, such as words for adults and words for children. In addition, although a drawing command of a rectangle, a circle, a character string, or the like is directly used as image data, a pixel value may be directly used.

【The invention's effect】

As described above, according to the present invention, the image data is composed of character image data composed of a plurality of data sets expressing different words with the same meaning as the non-character image data, and is temporarily held in the image data holding unit. Only the necessary data set is selected, and the selected data set (character image data) and the non-character image data are output by the image data output unit. There is no need to create data, it is only necessary to create a data set related to the character portion, and there is an effect that an image output device that can easily change words and phrases in a presentation or the like is obtained.
