Further, reference numeral 106 denotes each screen data partitioned and output from the key input unit 102, for example, position information of a screen section, pixel information of each pixel in the screen section, and color data in the screen section. As shown in the storage section, the data storage section 106 includes first to Nth data storage sections 106a to 106 therein to store data of each of the divided output screens.

Reference numeral 114 denotes a data combination unit for combining and outputting a screen selected and enlarged by the key input unit 102 and a plurality of reduced screens set in each section on the same screen. Screen data processing is performed in association with a plurality of reduced partitioned division screens and an entire reduced screen in which the entire screens are indexed, and a screen configuration algorithm for configuring the enlarged screen selected by the key input unit 102 into the same screen.

Also, reference numeral 116 denotes an output driver for converting the applied screen data combined from the data combination unit 114 into D / A conversion and primary color signals R. G. B and outputting the output unit 118 as a medium.

On the other hand, the reference numeral 120 receives a screen configuration setting signal (for example, screen partition setting / partition setting screen number / partition position setting) from the key input unit 102 and stores it in the screen setting unit 104 and each screen data. Is stored in the data storage units 106a to 106n, and when the selection key input signal is applied from the key input unit 102, the screen is controlled by controlling the screen configuration algorithm so that the selected screen is enlarged to the entire screen. And a control unit which controls the outputted screen data to be output through the output unit.

Hereinafter, an example of a screen partitioned and output will be described in detail with reference to the accompanying drawings. 2A and 2B illustrate screens output by a multi-screen output control apparatus in an application device according to an embodiment of the present invention.

Referring to this, a reduced full screen 202 in which the entire screen is indexed and output is formed, and the first screen 200 in which the portion to be edited is divided and enlarged on the full screen 202 is displayed.

In addition, the part of the full screen 202 to be edited next can be partitioned and output to the second screen 204, the third screen 206, and the fourth screen 208. Inside the first screen 200, the full screen 202 and the second to fourth screens 200, 204, 206, and 208 are output as reduced screens, respectively.

At this time, the multi-screen output control device 100 is largely performed the division setting control of each screen and mutual switching control at the time of output between each screen.

In more detail, the section set through the multi-screen output control apparatus 100 may be configured to operate the key input unit 102 to enlarge the entire screen 202 to the size of the first screen 200. Select the setting mode. Then, an information input field (not shown) for the number of divisions, the size, and the position of the screen is displayed.

At this time, the method of setting the number of divisions, the size, and the position of the screen is roughly divided into two setting methods, the first of which sets the size of the screen to be constant and the user inputs the key input unit 102 (for example, a mouse). When a specific position is selected in the enlarged full screen 202 by using a predetermined point (for example, A and B), a predetermined preset section is set to output a reduced screen. The second is to set an arbitrary section formed by continuously selecting the left button of the key input unit 102 (for example, a mouse).

On the other hand, the mutual switching control at the time of output between the screens of the multi-screen output control device 100 is a plurality of reduced screens (full screen and second, 3, 4; 202, 204, 206, 208) and the first screen 200) and the screen switching control. For example, when the key input unit 102 is selected to edit the second screen 204 that is reduced and output, the second screen 204 is enlarged and output by the size of the first screen 200. The first screen 200 is reduced to the position of the second screen 204 and output. In other words, the screen is mutually switched so that the screen of FIG. 2A is switched and output in the form of the screen of FIG. 2B.

Of course, by selecting a specific selection point (e.g., B) on the full screen 202, any partition screen (e.g., second screen; 204) including the selection point (e.g., B) is enlarged and output. It is also possible enough.

3 is a diagram illustrating a memory table of a multi-screen output control apparatus in an application device according to an embodiment of the present invention.

Referring to this, each screen data stored in the first to Nth data storages 106a to 106n is stored in a state where a different memory table 300 is provided, and the memory table 300 is The file name 302 of the screen data (e.g., the first screen), the size 304 of the set and output screen (e.g., 10 x 15), and the position 306 of the reduced screen output (306; e.g., 50 x 50 screens). (35 to 50) x (0 to 15)] is stored as one file.

With reference to the accompanying drawings, a multi-screen output control method in an application device according to an embodiment of the present invention having the above configuration will be described in detail.

4A and 4B are flowcharts illustrating signal flows of the multi-screen output control apparatus in the application apparatus according to the exemplary embodiment of the present invention.

First, a decision must be made as to whether the entire graphic data outputted when one graphic file data is extracted and outputted on a reduced screen. When the entire graphic data is indexed and output on one reduced screen (eg, 202 of FIG. 2A), the size and position of the reduced whole screen 202 must be set.

In the state where the full screen 202 is set, the full screen 202 is enlarged and output at the position of the first screen 200 in the same size as the first screen 200, and the full screen ( It is determined whether or not 202 is divided into a plurality of local screens and outputted.

If the output request signal of the multiple local screens for the full screen 202 is applied through the key input unit 102, the number of screen divisions for each local screen (eg, 204, 206, 208), the size of the screen, Set the screen position.

In this case, if the output of a plurality of local screens (eg, 204, 206, 208) is not selected, only the plurality of screens in which the full screen 202 and the full screen 202 are enlarged and output on the entire screen are output.

On the other hand, when the number of screen divisions for the local screen (eg, 204, 206, 208), the size of the screen, and the screen position are set, the screen section is designated, and the combination of data for outputting each screen on the same screen is described. It is made in the data combination unit 114.

Preferably, in the present invention, two setting methods are provided for the method of setting the screen partition, the first of which sets the size of the screen to be constant and the user uses the key input unit 102 (for example, a mouse). When a specific position is selected in the enlarged full screen 202, a predetermined preset section is set based on the selection points (for example, A and B) to output a reduced screen. Is to set an arbitrary section formed by continuously selecting the left button of the key input unit 102 (for example, a mouse).

When the data combination unit 114 combines the data for each screen on the same screen, the controller 120 drives the output driver 116 to select the specific selection screen 200 and the respective compartments. A plurality of output screens 202, 204, 206, and 208 are output on the same screen.

As a result, the editing operation for the specific selection screen 200 selected and output by the key input unit 102 can be executed. When the graphic editing is completed, the control unit 120 receives the data change and storage request signal from the key input unit 102 to update the existing graphic data.

Meanwhile, the present invention can reduce a specific enlarged screen (eg, 200) and request an enlarged output for the other reduced screen (eg, 202, 204, 206, 208), which is, for example, the second output in a reduced state. When the key input unit 102 is selected to edit the screen 204, the second screen 204 is enlarged and output by the size of the first screen 200, and the first screen 200 is The output is reduced to the position of the second screen 204. In other words, the screen is mutually switched so that the screen of FIG. 2A is switched and output in the form of the screen of FIG. 2B.

Of course, by selecting a specific selection point (e.g., B) on the full screen 202, any partition screen (e.g., second screen; 204) including the selection point (e.g., B) is enlarged and output. It is also possible enough.

On the other hand, the multi-screen output control method in the application device according to an embodiment of the present invention is not limited to the above-described embodiment is possible various modifications within the scope not departing from the technical gist.

As described above, according to the multi-screen output control method in the application device according to the present invention, the editing operation is made very easy by outputting a plurality of editing standby screens to the same one screen, each screen of the user Arbitrary division can be set to suit the setting division. In addition, when a plurality of reduced screens are selected, screen switching with the entire screen is possible, thereby making it possible to perform easy editing.
