Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

In the embodiments of the present invention, the control value of the main screen and the sub-screen is automatically calculated based on the control value set in the full screen and the previously stored weight information in the PIP mode, or the control value of the full screen is changed to the size of the main screen sub-screen. The method of calculating the control value of the main screen and the sub-screen by changing accordingly will be described.

2 is a flowchart illustrating a main screen and a sub-screen control process in the PIP mode according to an embodiment of the present invention.

1 and 2, first, a process of determining whether a main power 'ON' signal of a television is input through a key input unit 30 of a remote controller or a front panel of a television is performed (S200).

As a result of the determination in S200, when the main power ON signal of the television is input, the television is turned ON (S202), and if the main power ON signal of the television is not input, the standby state is continuously maintained.

Subsequently, the microcomputer 40 determines whether a PIP mode setting key signal for dividing the two screens of the television from the key input unit 30 is input (S204).

As a result of the determination of S204, when the PIP mode setting key signal is not input, the broadcast signal is displayed on one screen, that is, the entire screen (S206), and when the PIP mode setting key signal is input, the microcomputer 40 stores the memory unit ( In step 50, the screen control value is retrieved in the normal mode.

Then, the microcomputer 40 changes the control value of the searched main screen and sub-screen by using the screen size of the main screen and the sub-screen, that is, the contrast ratio of the entire screen, in the PIP mode. Next, the calculated control values of the main screen and the sub-screen are stored in the memory unit 50 (S210). In this case, the control value may include contrast, brightness, color value, and the like. In the normal mode, the control value of the screen (full screen) is determined by a user's menu call.

As an example of calculating the control value of the main screen and the sub-screen according to the control value of the screen, as the size of the main screen or sub-screen becomes smaller than the total screen size, the main screen control value is increased. As the size becomes smaller like 1/2, 1/4, or 1/8 of the full screen size, the control value of the sub-screen is set by increasing the contrast, brightness, and color values of the main screen.

Then, the microcomputer 40 controls the PIP processing unit 70 to set the PIP mode, thereby displaying the main screen and the sub-screen based on the channel selected by the user (S212). Based on the control value of the screen, the contrast, brightness, color value, etc. of the main and sub screens are controlled.

According to one embodiment of the present invention, by automatically calculating the control value of the main screen and the sub-screen based on the control value set on the screen in the normal mode and the size of the main screen and the sub-screen, the user directly in the PIP mode There is no need to adjust the brightness, contrast, color values, etc. of the subscreen.

3 is a flowchart illustrating a control process of a main screen and a sub screen in a PIP mode according to another embodiment of the present invention.

1 and 3, first, a process of determining whether a main power 'ON' signal of a television is input through a key input unit 30 of a remote controller or a front panel of a television is performed (S300).

As a result of the determination in S300, when the main power ON signal of the television is input, the television is turned ON (S302), and if the main power ON signal of the television is not input, the standby state is continuously maintained.

Thereafter, when the menu call signal for inputting control value weight information of the main screen and the sub-screen is input from the key input unit 30 (S304), the microcomputer 40 displays an input window for inputting the weight information on the display unit 120. In operation S304, the weight information input to the input window is stored in the memory unit 50. In this case, the input window for inputting the weight information may include an interface for inputting weight information on contrast, brightness, color value, and the like.

Thereafter, the microcomputer 40 determines whether a PIP mode setting key signal for separating the television from two screens is input (S306).

When the PIP mode setting key signal is not input, the broadcast signal is displayed on one screen, that is, the entire screen (S308). When the PIP mode setting key signal is input, the microcomputer 40 stores the memory unit ( The control value and weight information of the entire screen stored in 50) are retrieved, and then the control values of the main screen and the sub-screen are calculated using the same (S310).

In the method of calculating the main screen and the sub-screen control values, the main screen and the sub-screen control values are calculated through an operation between a control value of the entire screen and weight information, for example, an operation of adding, subtracting, multiplying, or dividing. The calculated control values of the main screen and the sub screen are stored in the memory unit 50.

Then, the microcomputer 40 controls the PIP processing unit 70 and sets the PIP mode to display the main screen and the sub screen based on the channel selected by the user (S312), based on the control value of the main screen. The contrast, brightness and color values of the main screen are controlled, and the contrast, brilliance and color values of the main screen are controlled based on the control values of the sub-screen calculated in S310.

According to other embodiments of the present invention, in the PIP mode, the user automatically calculates the control values of the main screen and the sub-screen based on the control value set on the entire screen and the pre-stored weight information, so that the user directly brightens the main screen and the sub-screen. There is no need to adjust varnish, contrast, color values, etc.
