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.

을 대입해도 동일한 결과를 얻을 수 있음을 알 수 있다. 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')

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) As shown in FIG. 2, if the square variable is set to m when the square increases by two cars, the increasing number of channels may be defined as in Equation 2 below.

m ² -(m-2) ² = 4 m-4 (where m≥3)

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). This result can be seen that the same result can be obtained by substituting the square variable m in Equation (2).

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

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) As shown in FIG. 2, if the square variable is set to n when three squares increase, the increasing number of channels may be defined as in Equation 3 below.

n ² -(n-3) ² = 6n-9 (where ≥ 4)

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). This result can be seen that the same result can be obtained by substituting the square variable n in Equation (3).

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

Example of 28-channel partitioning method (first case)

Next, a method (first case) of dividing one monitor screen into 28 screens (channels) while maintaining the aspect ratio (16: 9, 4: 3, etc.) of each channel will be described.

Table 1 below shows the number of screens (channels) that are increased or decreased when the channel of the current screen is increased by one square from 4 channels in the current screen. In this case, the increase / decrease value of the screen (channel) can be simply obtained by applying Equation 1 or Equation 4.

Table 2 below shows square types and variable values obtained by Equation 4 when the increase / decrease value A of the channel is 24 (square 2 × 2). Table 2 starts with a 2 × 2 square.

Square variables from the equation

This means that there are three square 2x2 channel screens (since x = 3). Here, the meaning that there are three squares 2 × 2 means that three values change from one square (1 × 1) to two squares (2 × 2) as described above. For example, as shown in FIG. 10, when the monitor screen has four channels (2 × 2), four channels have one channel (1 × 1) screen, and three channel screens (1 ×) are included. It means that 1) is converted to 4 channel (2 × 2) screen.

In the column ⓐ of Table 2, γ = 15 means that the square variable n = 1 from the equation γ = 6n-9 , so that there is one square 4 × 4 channel screen (since z = 1). It means. As before, there is one square 4 × 4 channel screen, which means that there is one side that changes from 1 channel (1 × 1) screen to 16 channels (4 × 4) screen (16 split screen). It means. For example, in FIG. 10, one channel screen 1 × 1 out of four channels is converted into a screen of 16 channels (4 × 4).

Accordingly, in the method of converting a 4-channel (2 × 2) screen into a 28-channel split screen, as shown in FIG. 10, three channel screens (1 × 1) are divided into four channels (4 × 2) out of the four-channel (2 × 2) screens. When the screen is converted into a 2 × 2 screen and the remaining one channel screen 1 × 1 is converted into a 16-channel (4 × 4) screen, a 28-channel divided screen can be obtained.

In the column ⓑ of Table 2, β = 8 means that the square variable m = 3 from the equation of β = 4m-4 , which means that there are three square 3 × 3 channel screens (since y = 3). . Here, the meaning that there are three square 3 × 3 means that the value of changing from one square (1 × 1) to three squares (3 × 3) is three as described above. For example, as shown in FIG. 11, when the monitor screen has four channels (2 × 2), four channels have one channel (1 × 1) screen, of which three channel screens (1 ×) are included. This means that 1) is converted to 9 channels (3 × 3) screen.

In the column ⓑ of Table 2, γ = 15 means square variable n = 0 from the equation γ = 6n-9 , which means that there are 0 square 4 × 4 channel screens (since z = 0). to be. As before, this means that there are 0 square 4 × 4 channel screens, which means that there are 0 faces that change from 1 channel (1 × 1) screen to 16 channel (4 × 4) screen (16 split screen). It means. This means that the screen of one channel (1 × 1) is not converted. For example, in FIG. 11, it can be seen that one channel screen (1 × 1) of four channels remains undivided.

Accordingly, in the method of converting a 4-channel (2x2) screen into a 28-channel split screen, as shown in FIG. 11, three channel screens (1x1) are divided into 9-channel (4x2) screens. When the screen is converted into a 3 × 3 screen and the remaining one channel screen 1 × 1 is not converted, and one channel screen 1 × 1 is kept as it is, 28 channel divided screens can be obtained.

Here, the meaning that there are eight square 2 × 2 means that the value of changing from one square (1 × 1) to two squares (2 × 2) is eight as described above. For example, as shown in FIG. 10, when the monitor screen has four channels (2 × 2), four channels have one channel (1 × 1) screen, and four channel screens (1 ×) are included. 1) is converted into a four-channel (2x2) screen, and when the converted four-channel (2x2) screen is converted into a four-channel (2x2) screen again, a 24-channel split screen can be obtained. .

Embodiment for 28 channel division method (second case)

A method of dividing one monitor screen into 28 screens (channels) while maintaining the aspect ratio (16: 9, 4: 3, etc.) of each channel will be described using the second case.

Table 3 below shows the number of screens (channels) that are increased or decreased when the channel of the current screen is increased by two squares from 4 channels in the current screen. In this case, the increase / decrease value of the screen (channel) can be simply obtained by applying Equation 2 or Equation 4.

This means that there is one square 2 × 2 channel screen (since x = 1). Here, the fact that there is one square 2 × 2 means that one value is changed from one square (1 × 1) to two squares (2 × 2) as described above.

In the column ⓐ of Table 4, since β = 8 means that the square variable m = 3 from the expression of β = 4m-4 , there are two square 3x3 channel screens (since y = 2). It means. Here, the fact that there are two square 3 × 3 means that the value is changed from one square (1 × 1) to three squares (3 × 3).

In the column ⓐ of Table 4, γ = 15 means square variable n = 0 from the equation γ = 6n-9 , which means that there are 0 square 4 × 4 channel screens (since z = 0). to be. In this case, 0 square screens of 4x4 channels means that there are 0 faces that change from 1 channel (1x1) screen to 16 channels (4x4) screen (16 split screens). . In other words, there is no screen that is converted from a one-sided (1 × 1) screen to a four-sided (4 × 4) screen.

Therefore, the method of converting a 4-channel (2x2) screen into a 28-channel split screen is as shown in FIG. 12. In the case where the monitor screen has nine channels (3x3), nine channels are one channel (1x1). ) Consists of nine screens, of which one channel screen (1 × 1) is converted to a four-channel (2 × 2) screen, and two channel screens (1 × 1) are nine channels (3 ×). By switching to the screen of 3), a divided screen of 28 channels can be obtained.

In the column ⓐ of Table 4, since β = 8 means that the square variable m = 3 from the equation of β = 4m-4 , there are zero square 3 × 3 channel screens (since y = 0). It means. Here, the square 3x3 has zero planes means that the value of changing from one square (1x1) to three squares (3x3) has zero planes. That is, there is no screen that is converted from a one-sided (1 × 1) screen to a three-sided (3 × 3) screen.

In the column ⓐ of Table 4, γ = 15 means square variable n = 0 from the equation γ = 6n-9 , which means that there are zero square 4 × 4 channel screens (since z = 0). to be. In this case, 0 square screens of 4x4 channels means that there are 0 faces that change from 1 channel (1x1) screen to 16 channels (4x4) screen (16 split screens). . In other words, there is no screen that is converted from one square (1 × 1) screen to three squares (4 × 4).

Therefore, the method of converting from 16-channel (4x4) screen to 28-channel split screen is as shown in FIG. 13, when the monitor screen has 16-channel (4x4), 16-channel is 1 channel (1x1). ) Is composed of 16 screens, of which four channel screens (1x1) are converted into four-channel (2x2) screens, whereby a 28-channel split screen can be obtained.

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.

A _Formula = 3x _{1 → 4} + 5x ' _{4 → 9} + 7x " _{9 → 16} + 8y _{1 → 9} + 12y ' _{4 → 16} + 16y " _{9 → 25} + 15z _{1 → 16} + 21z ' _{4 → 25} + 25z " _{9 → 36}

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

That is, X _{1 → 4} means that one square is changed into two squares (two channels x two channels), that is, the number of channels is changed from one to four channels.

Likewise, Y ' _{4 → 16} means that the quadrilateral (2-channel x 2-channel) is changed to quadrilateral (4-channel x 4-channel), and the number of channels is changed from 4 to 16 channels.

Here, each of X, X ', X ", Y, Y', Y", Z, Z ', and Z' refers to the number of screens changed as described above.

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.

2) Split formula A to be applied

3x _{1 → 4} + 5x ' _{4 → 9} + 7x " _{9 → 16} + 8y _{1 → 9} + 12y' _{4 → 16} + 16y" _{9 → 25} + 15z _{1 → 16} + 21z ' _{4 → 25} 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} ".

And, applying the above equation (9),

8 = 3x _{1 → 4}  + 7x " _{9 → 16} + 12y ' _{4 → 16}

₁ x _{1 → 4} = 1, x ' _{9 → 16} = -1, z _{4 → 16} = 1

25 illustrates a method of dividing a 16-channel (4x4) screen into 17-channel screens.

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

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}

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

or,

-19 = 3x _{1 → 4}  + 8y _{1 → 9}

∴ 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 → 1 6} , and the value is x _{1 → 4} = 1, x' _{9 → 16} = -1, z _{4 → 16} = 1 At this time, the shape of the screen division that can come out from these values can be variously expressed as shown in FIGS. 28A to 28C.

If the starting square B starts in the shape of a 5-square (5 × 5), it is 20 = 25 + A ₂₅ from Equation 10, and A ₂₅ = -5 . Then, if the division formula A to be applied is 3x + 5x '+ 8y = -5, x' = -1.

In this case, in the 25 split screen, since x '= -1, there is one that the quadrilateral (3x3) rectangle is changed to the bilateral (2x2) rectangle.

6) Example of screen division from 36 channels to 20 channels

If the starting square B starts in the shape of a hexagonal shape (6 × 6), 20 = 36 + A ₃₆ from Equation 10, and A ₃₆ = -16 . Then, if the division formula A to be applied is 3x + 5x '+ 8y = -16, x' = -2, x = -2.

To interpret this, in 36 split screens, there are two cases where two rectangles (2 × 2) are replaced by one rectangle (1 × 1) because x = -2, and three rectangles (3 because x '= -2). There are two things in which the square of x3) is changed into a rectangle of 2 squares (2x2).

Application example

The field of application of the screen division algorithm according to the present invention is very diverse.

As display devices, including DVRs, have increased to high channels, screen division functions, optimal channel division selection methods, and algorithms for screen channel selection in large TVs are required. In particular, the screen dividing algorithm of the present invention in a large display device such as a TV can make it possible to display an optimal screen.

As described above, the screen splitting method according to the present invention describes the basic algorithm.

first. A method of dividing the screen into the desired number of screens from the currently displayed screen may be selected by the above-described algorithm, but may be displayed by presetting the screen having the highest preference among the plurality of split screens. In this case, the user can change the screen division method to be used.

For example, referring to FIGS. 23 to 28C, the screen divided into 17 pieces may exist in addition to the types illustrated on the screen. If there are multiple screen splitting methods, a specific split screen can be specified and displayed when shipped from the factory. Also, if the user wants to change the screen, the split screen can be displayed and selected by the user. You can do it.

It is preferable to designate such a preset screen such that the main screen is centered as shown in FIG. 26A.

In this case, the screen disposed at the center is displayed to be identifiable, but if it is determined that identification of other surrounding screens is difficult, the user's manipulation or automatically may alternately select all channels on the center screen.

second. As described above, when the preset screen is changed by a predetermined number of times or respecified by the user's favorite screen dividing method, the screen dividing method is stored, and when it is displayed again, the preset screen dividing method is displayed. Can be.

third. As described above, when the main screen is set, it is more preferable that the user places the favorite channel on the main screen.

These favorite channels can be detected or preset by counting a certain number of times.

fourth. This division scheme can be used not only for channel division schemes such as TV but also for displaying stored contents.

For example, in the case of MP3, when displaying several songs including title songs, title songs can be placed on the main screen and other songs on other screens.

In this case, the number of screens to be split may be specified and displayed. In particular, when the amount of content to be displayed is constant, it is preferable to split the screen automatically by the number. In other words, if there are ten contents to be displayed, the screen can be divided into ten screens and the title song can be placed on the main screen.

In particular, when an appropriate maximum screen division number is specified according to the size of the display device, when the amount of content to be displayed exceeds the maximum division number, the next page may be set to display continuously. .

In addition, of course, it can be used also when displaying a Windows directory. That is, when displaying subdirectories, the upper directories are displayed in a split screen in turn, and if the files in the directories can be displayed, the user can intuitively grasp the contents related to the directory. In this case, if the number of screen division is changed according to the number of upper directories, the contents of the directory can be effectively checked.

Five. In particular, when a content such as a still image of a digital camera is to be displayed, it may be displayed as a thumbnail. Thumbnails are thumbnails of your photos, make them easier to read as you browse through them, and treat them as if they were regular string indexes. Photo images must be displayed on a display device with a native resolution to identify them. When displaying such content, the number of contents that can be displayed is limited when the display device is small, such as a mobile phone or a PMP. It is compressed so that it is displayed.

Sixth. The screen division method of the present invention may divide and display a predetermined screen, which is already divided in the screen of the display device, by dividing by the desired number of channels. A detailed description will be given below.

As described above, although the application example of the present invention has been described, various embodiments of the present disclosure cannot be described by using the limited surface. Therefore, the present invention is not limited thereto, but the present invention is not limited thereto. Please note that can be used with any device.

Hereinafter, a PIP screen will be described in detail with reference to a method of dividing and displaying a predetermined screen, which is already divided in the display device screen, by the desired number of channels.
