JP2708912B2 - Screen expansion control method for multi-screen display device - Google Patents

Description

The present invention relates to a method for controlling the screen development of a multi-vision (multi-screen display device).

(B) Conventional technology An image enlargement multi-screen display device called a multi-vision is disclosed in JP-B-64-6592 (H04N5 / 44) and JP-A-57-101481.
No. (H04N5 / 68).

By the way, in this multi-vision, which screen is to be displayed at which magnification at each screen is set, and this setting is switched to display various images. The switching of the setting is performed by the enlargement ratio of the image enlargement device,
This is performed by switching the enlarged portion and its input and its output.

And "Television Society Journal Vol.39, No.7 (1985
As shown in Matsuura's “3-3-1 Multivision” on pages 31p to 34p of “Year), the above-mentioned switching is difficult by manual operation for quickly and orderly switching a large number of circuits. Normally, it is automatically switched by computer control.

Such an example will be described with reference to FIGS. 3 to 5. FIG. 3 is a schematic diagram of a multi-screen display device. (10) is a video signal generating means, and the video signal generating means (10)
Comprises a video tape recorder, a TV tuner, a video disk, and the like. (12) is a display section comprising 16 monitor displays (a) to (p).

(14) is an enlargement switching control circuit. (16) is a video signal input switching circuit. (18) is a video signal output switching circuit. (20) is a video signal enlargement circuit. (22) is a control circuit, and (24) is a program memory circuit. (26) is a system controller.

The above control will be briefly described. For example, consider the screen development shown in FIG. In the drawing, A indicates that the video signal (A) is displayed on the monitor, and B indicates that the video signal (B) is displayed. When (A) or (B) extends over a plurality of monitors, an enlarged image is shown.

When the screens shown in FIGS. 4 (a), (b) and (c) change one after another in the order of 10 seconds → 5 seconds → 8 seconds →, the program of the system controller (26) is as shown in FIG.

The system controller (26) outputs this program to the enlargement switching control circuit (14). This program is stored in the program memory circuit (24) via the control circuit (22). The control circuit (22) selects and distributes the video signal in the video signal input switching circuit (16), selects and distributes the video signal in the video signal output switching circuit (18), The enlargement ratio in the enlargement circuit (20) and the designation of the enlarged screen portion are controlled, and the fourth
The screen corresponding to the figure is projected on 16 monitors (a) to (p).

(C) Problems to be Solved by the Invention As shown in FIG. 4, screens are developed one after another by executing a program. However, if the user wants to check the appearance when a video such as a moving image is actually displayed on the monitor by this development, he or she wants to stop during the development. Therefore, apart from the above-mentioned program, FIGS. 4 (a) and 4 (b)
Programs corresponding to (c) must be separately created, which is troublesome. Further, an extra memory for storing these programs is required, which increases the required memory capacity.

Furthermore, even if each step can be executed alone or in combination with several steps, the duration set for the step is not affected even if it alone is to check the appearance of the screen. Until the process is completed, the next operation cannot be performed, and there is a disadvantage that the efficiency of creating the screen development program is not improved.

(D) Means for Solving the Problems The present invention provides a video signal generating means (10), a plurality of display means (a to p), and an image from the video signal generating means (10) at an arbitrary magnification. An enlargement switching control circuit (14) for selectively outputting the enlarged signal to the plurality of display means (a to p), and a screen development program for controlling a temporal operation of the enlargement switching control circuit (14) are described above. A screen development control method for a multi-screen display device, comprising a system controller (26) for outputting to an enlargement switching control circuit (14), wherein the screen development program comprises a plurality of steps, each of which is at least each step. The duration, display magnification, and information about the video input selection, and when executing the entire development program,
Based on the duration of each step, the display according to each step information is performed by the plurality of display means, and when one of the steps is executed, the restriction on the duration of each step is released. A display development control method for a multi-screen display device, wherein the display according to the other information of each step is performed by the plurality of display units.

(E) Function In the present invention, a program is created from a plurality of steps, and the program is executed for each step.

(F) Example FIG. 1 shows a program of the present invention. As can be seen from FIG. 1, the program of the present invention comprises a plurality of steps 1, 2, 3
Do more. FIG. 2A shows an operation display section of the system controller (26). The display is operated by a touch panel system.

In this embodiment, the program is composed of a plurality of steps as shown in FIG. Then, by touching the normal execution section (30) shown in FIG. 2, this program is downloaded to the program memory circuit (24),
This program is executed as before. Then, when it is desired to execute only step 1, the operator touches the online section (32) → step execution section (34) → “1” section (36) in FIG. Is downloaded in the same manner as described above, and the screen shown in FIG. 4A is displayed. At this time, there is no limit on the duration of step 1.

Also, if the on-line section (32) → step execution section (34) → “1” section (36) → “3” section (40) in FIG. 2 is touched, the steps “1” and “3” in FIG. Is downloaded and the state of FIG. 4A continues for 10 seconds, and then the state of FIG. 4C is reached, and this state continues similarly.

The off-line section (28) determines the start time of the step execution,
An operation unit for temporarily stopping the operation until the online unit (32) is touched. That is, it is assumed that a certain program is already being executed. Then, the operator sets the offline unit (28) → the step execution unit (34) → the “1” unit (3
6) Even if you touch, the previous program is executed. Then, when the operator touches the online section (32), the program of step "1" is downloaded, and the screen becomes as shown in FIG. 4A.

In the above embodiment, when the program of each step is executed, the program to be downloaded to the program memory circuit (24) is rewritten. However, the program is separately downloaded to the program memory circuit (24). Data indicating which step of the program is to be executed may be output from the system control circuit (26). At this time, the data indicating the touch operation of the online unit (32) or the touch operation of the offline unit (28) and the start address data corresponding to the designated step of the corresponding program memory circuit (24) are Sent out.

(G) Effects of the Invention As described above, according to the present invention, partial execution of a program can be easily performed in a multi-screen display device.

In this case, the restriction on the duration of the step is released, so that the screen development program can be efficiently created.
