Abstract

PURPOSE:To obtain the output results of the same image by converting all of data to be displayed and printed to picture data and returning this data to a processor. CONSTITUTION:A multimedium output means 2 receives data of one page to be displayed/printed out of multimedium data 11 in a data processor 1. All of assigned data of one page is converted to picture data and this data is returned to the processor 1. This processing is repeated till all of data to be printed is completely converted. A picture element density converting means 12 checks the picture element density of an output device corresponding to the means 2 and that corresponding to another output means 3 to discriminate whether both of them coincide with each other or not. If they are different, the picture element density of the output device corresponding to the means 2 is converted to that corresponding to another means 3. This data is sent to the means 3 from a picture re-output means 13. It is displayed/printed by the corresponding output device. Thus, images of both picture data are equal to each other. Thus, the output results of the same image are obtained.

In the conventional multimedia output method described above, in order to maintain the same image output on various output devices, it is necessary to process the data and format information in the multimedia data, so the processing burden is large. It has the disadvantage of becoming.

In addition, there is a drawback that simply processing data and format information in multimedia data does not necessarily produce the same image output between various output devices with different formats. For example, there is a drawback in that output devices that use different character fonts and the like often cannot produce the same image of the font, size, etc. of character data.

In view of the above-mentioned points, an object of the present invention is to provide a multimedia output method that can easily obtain output results of the same image on various output devices when outputting data in multimedia data.

[Means to solve the problem]

The multimedia output method of the present invention is a data processing system that displays/prints data in multimedia data on various output devices, and displays/prints data in multimedia data page by page based on format information.
A multimedia output means that prints and returns the displayed/printed data as image data to a data processing device, and another multimedia output means that outputs pixel density of the image data sent back to the data processing device by this multimedia output means. pixel density conversion means within the data processing device for converting the pixel density to match the pixel density of the output device corresponding to the pixel density of the output device;
and image re-output means within the data processing device for sending the image data whose pixel density has been converted by the pixel density conversion means to the other multimedia output means.

C Effect] In the multimedia output method of the present invention, the multimedia output means displays/prints the data in the multimedia data on the output device page by page based on the format information, and outputs the displayed/printed data as image data. The pixel density conversion means in the data processing device converts the pixel density of the returned image data to the pixel density of the output device corresponding to other multimedia output means by the multimedia output means. The image re-output means in the data processing device sends the image data whose pixel density has been converted by the pixel density conversion means to the other multimedia output means.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a multimedia output method according to an embodiment of the present invention. The multimedia output system of this embodiment includes a data processing bag 21, a multimedia output means 2, and another multimedia output means 3. Note that the multimedia output means 2 and the other multimedia output means 3 each have a corresponding output device! (not shown) exists.

The data processing device 1 includes multimedia data II including data to be displayed/printed, pixel density conversion means 12,
It is configured to include an image re-output means 13.

The multimedia data 11 includes character data, graphic data, graph data, image data, etc. (in addition to the listed data, for example, there is image data), and format information for allocating these data (multimedia data). The data to be displayed/printed in [media data 1] may be a single type of data or a mixture of various types of data).

FIG. 2 is a flowchart showing the processing of the multimedia output means 2. As shown in FIG. This process includes a step 21 of receiving data for one page, a step 22 of determining the existence of data for one page,
It consists of a step 23 for generating image data for one page, a step 24 for displaying/printing image data for one page, and a step 25 for returning image data for one page.

FIG. 3 is a flowchart showing the processing of the pixel density conversion means 12. This process includes a pixel density identity determination step 31;
Wfi elementary density conversion processing step 32.

Next, the operation of the multimedia output method of this embodiment configured as described above will be explained.

The multimedia output means 2 receives data to be displayed/printed in the multimedia data 11 page by page from the data processing device 1, visualizes the data page by page, and outputs the data to the corresponding output device. At the same time, the displayed/printed image is returned to the data processing device l (data sending source) as image data.

That is, the multimedia output means 2 performs the following processing (see FIG. 2).

First, multimedia data 11 in data processing device 1
One page's worth of data (character data, graphic data, graph data, and image data may be single or mixed) to be displayed/printed is received (step 21).

In this step 21, it is determined whether one page of data could be received (whether or not the data to be displayed/printed remained in the multimedia data 11).
Step 22).

If it is determined that "data for one page could not be received", the process is terminated.

If it is determined in step 22 that "I page worth of data could be received", that one page worth of data is allocated according to the format information in the multimedia data 11, and the allocated one page is All data for one image is converted into image data (dot data) (step 23).

Next, one page of image data generated (converted) in step 23 is displayed/printed on a corresponding output device (step 24).

Furthermore, the image data for one page generated in step 23 is sent back to the data processing device 1 (data sending source) (step 25).

The above process is repeated until no data to be displayed/printed remains in the multimedia data 11 as determined in step 22.

The pixel density conversion means 12 in the data processing device 1 outputs the image data generated by the multimedia output means 2 to the other multimedia output means 3 while maintaining the same image. The pixel density of the image data is converted in accordance with the pixel density of the output device corresponding to the image data.

That is, the pixel density conversion means 12 performs the following processing (see FIG. 3).

First, the pixel densities of the output device corresponding to the multimedia output means 2 and the output device corresponding to the other multimedia output means 3 are checked to determine whether they are the same (step 31).

If this determination shows that both pixel densities are the same, the process ends without performing anything.

If the pixel densities of the two are different as determined in step 31, the pixel density of the output device corresponding to the multimedia output means 2 is changed to the pixel density of the output device corresponding to the other multimedia output means 3. A process of converting the pixel density is performed (step 32), and then the process ends.

The image re-output means 13 in the data processing device 1 transfers the image data whose pixel density has been converted by the pixel density conversion means 12 to another multimedia output means 3 (the other multimedia output means 3 is a multimedia output means 2 or may be any multimedia output means in the prior art).

Other multimedia output means 3 includes image re-output means 13
The image data sent from the device is displayed/printed on the corresponding output device. The image of the image data displayed/printed in this manner is the same as the image of the image data displayed/printed on the output device corresponding to the multimedia output means 2.

〔Effect of the invention〕

As explained above, the present invention allows the multimedia output means to display/display multimedia data in the data processing device.
By converting all the data to be printed into image data and sending it back to the data sending source (data processing device), when outputting data in multimedia data to various output devices, character fonts can be exchanged between output devices. Even if the images are different, the output result of exactly the same image can be easily obtained on various output devices.
