Split Screen Method

Dividing a monitor screen into a plurality of screens (channels) while maintaining the aspect ratio (16: 9, 4: 3, etc.) of each channel is as follows. Implementation is possible.

For example, when dividing a 4-channel (2 × 2) monitor screen into seven screens (7 channels) while maintaining the aspect ratio (16: 9, 4: 3, etc.) of each channel, as shown in FIG. Similarly, if one monitor screen is divided into four screens (square 2 × 2), and one screen among the divided four screens is divided into four screens (square 2 × 2), the aspect ratio of each channel ( 16: 9, 4: 3, etc.) can be divided into seven screens (7 channels). That is, when one channel screen is divided into square 2x2 among the screen composed of 4 channels, 3 channels are increased from the first 4 channels to be divided into 7 channels.

Therefore, using this principle can be summarized as follows.

1) When the square increases by one car (hereinafter 'first case')

로 놓으면, 증가하는 채널 수는 아래 수학식 1과 같이 정의할 수 있다.When one screen of the monitor changes from 4 channels (2 × 2) to 9 channels (3 × 3) (Fig. 4) and from 9 channels (3 × 3) to 16 channels (4 × 4) (Fig. 5) For example, if the square increases by one car,

If set to, the increasing number of channels can be defined as in Equation 1 below.

That is, when the screen is changed from 4 channels (2 × 2) to 9 channels (3 × 3), 3 channels are increased (see FIG. 4), and 9 channels (3 × 3) are changed to 16 channels (4 × 4). In this case, 7 channels are increased (see FIG. 5). This result is a square variable in Equation 1

It can be seen that the same result can be obtained by substituting.

2) If the square increases by two cars (hereinafter 'second case')

으로 놓으면, 증가하는 채널 수는 아래 수학식 2와 같이 정의할 수 있다.When one screen of the monitor changes from 4 channels (2 × 2) to 16 channels (4 × 4) (Fig. 6) and from 9 channels (3 × 3) to 25 channels (5 × 5) (Fig. 7) If the square increases by two,

If set to, the increasing number of channels can be defined as in Equation 2 below.

That is, when the screen is changed from 4 channels (2 × 2) to 16 channels (4 × 4), 12 channels are increased (see FIG. 6), and 9 channels (3 × 3) are changed to 25 channels (5 × 5). In this case, 16 channels are increased (see FIG. 7). The result is square variable in Equation 2 It can be seen that the same result can be obtained by substituting.

3) If the square increases by three cars (hereinafter 'third case')

으로 놓으면, 증가하는 채널 수는 아래 수학식 3과 같이 정의할 수 있다.When one screen of the monitor changes from 4 channels (2 × 2) to 25 channels (5 × 5) (Fig. 8) and from 9 channels (3 × 3) to 36 channels (6 × 6) (Fig. 9) If the square increases by three differences,

If set to, the increasing number of channels can be defined as in Equation 3 below.

을 대입해도 동일한 결과를 얻을 수 있음을 알 수 있다. That is, when the screen is changed from 4 channels (2 × 2) to 25 channels (5 × 5), 21 channels are increased (see FIG. 8), and 9 channels (3 × 3) are changed to 36 channels (6 × 6). In this case, 27 channels are increased (see FIG. 9). The result is a square variable in Equation 3

It can be seen that the same result can be obtained by substituting.

Based on Equations 1 to 3, Equation 4 may be generated.

As described above, there are three methods for creating a 32 channel split screen as described in the first to third embodiments (see FIG. 18).

In this way, all the split screens between 16 splits and 32 splits can be created without leaving an idle area.

Split screen algorithm

Mathematical formulating to create the desired number of divisions without any idle area and to maintain a constant ratio of each rectangle (e.g. 16: 9, 4: 3, etc.) is very complex considering multiple correlations. Do. Therefore, in the present invention, since it is not a mathematical paper, I would like to discuss it from the standpoint of methodology using the result and conclude with an intuitive method and application method.

In conclusion, the method of dividing the screen without leaving an idle area is as follows.

C = B + A

Where C is the target division factor, B is the starting square, and A is the division equation.

Here, the subscript of the division formula indicates that the "screen square" is converted into another "square division".

Such an algorithm maintains a constant ratio (16: 9 or 4: 3) and can include all geometric partitions that can be represented without an idle area. After that, the most beautiful screen division is selected aesthetically from the screen division derived from these results.

On the other hand, Equation (8) shows the equation that can be used most often from 4 channels to 64 channel divisions, and Equation (9) below shows the equation (8) further reduced.

When represented by A ₂₅ ,

3) 17 = A _5x5 + 25.

If we expand this, if we start dividing squares into 2x2, 3x3, 4x4, 5x5, 6x6,

As a result, the division formula "A _{division formula} " may have 13, 8, 1, -8 and -19. Here, various shapes of 17 divisions can be obtained depending on which equation is applied to "A _{division equation} ".

First, FIG. 23 illustrates a method of dividing a 4-channel (2x2) screen into 17-channel screens.

In Equation 10, 17 = A _{2 × 2} + 4, ∴ A _{2 × 2} = 13

And, applying the above equation (9),

13 = 3x _{1 → 4} + 5x ' _{4 → 9} + 15z _{1 → 16}

In Equation 10, 17 = A _{4 × 4} + 16, ∴ A _{4 × 4} = 1

And, applying the above equation (9),

1 = 3x _{1 → 4} + 5x ' _{4 → 9}

∴ x _{1 → 4} = 2, x ' _{9 → 16} = -1

26A and 26B illustrate a method of dividing a 25-channel (5 × 5) screen into 17-channel screens.

In Equation 10, 17 = A _{5 x 5} + 25, ∴ A _{5 x 5} = -8

And, applying the above equation (9),

-8 = 8y _{1 → 9} ∴ y _{1 → 9} = 1

or,

-8 = 3x _{1 → 4} + 5x ' _{4 → 9}

₁ x _{1 → 4} = -1, x ' _{4 → 9} = -1

27A and 27B illustrate a method of dividing a 36-channel (6 × 6) screen into a 17-channel screen.

In Equation 10, 17 = A _{6 × 6} + 36, ∴ A _{6 × 6} = -19

And, applying the above equation (9),

-19 = 3x _{1 → 4} + 5x ' _{4 → 9} + 21z' _{4 → 25}

₁ x _{1 → 4} = -1, x ' _{4 → 9} = 1, z' _{4 → 25} = -1

or,

-19 = 3x _{1 → 4} + 8y _{1 → 9}

₁ x _{1 → 4} = -1, y _{1 → 9} = -2

Meanwhile, the equation applied when the target division factor is 8 is as follows.

8 = 3x _{1 → 4} + 7x " _{9 → 16} + 12y ' _{4 → 16} and the value is x _{1 → 4} = 1, x' _{9 → 16} = -1, z _{4 → 16} = 1 The shape of the screen division that can be derived from these values can be variously expressed as shown in FIGS. 28A to 28C.

29 and 30 show examples of applying a division algorithm from 17 divisions to 20 divisions with the value of Equation 10. FIG.

Such an algorithm can derive a variety of geometric shapes, such as square division, 9 division, and 16 division, and can be arranged differently according to the importance of the image.
