Therefore, the definition should be made based on the contents throughout the specification.

1 is a block diagram for a navigation display method according to a preferred embodiment of the present invention, the GPS receiver 10, the sensor sensor 20, the memory reader 30, the navigation input unit 40 and the control unit 50 and the translucent display control part 60 are included.

The GPS receiver 10 receives the position information of the vehicle from the GPS satellites through the antenna and provides it to the controller 50.

The sensor detecting unit 20 is composed of a gyro sensor and a speed sensor to detect the rotation angle and the speed of the vehicle and provide it to the control unit 50.

The memory reader unit 30 is detachable from the memory card, and stores map data and other information for displaying such that vehicle location information is displayed on a map.

The navigation input unit 40 has a plurality of keys and a remote controller, and is a block for interfacing between the user and the control unit 50 in the navigation. The navigation input unit 40 inputs destination information to the control unit 50.

The controller 50 calculates the current position of the vehicle based on the rotation angle and the speed of the vehicle detected by the sensor detector 20, and corrects the cumulative error based on the position information of the vehicle received by the GPS receiver 10. While calculating the final driving information of the vehicle such as the vehicle's current position as well as the vehicle's driving speed and direction, and then the direction from the navigation input unit 40 to the destination information input based on the calculated final driving information. The left and right rotation information is extracted and configured to be applied to alpha blending by software in real time and provided to the translucent display control unit 60.

The translucent display control unit 60 is a block in which a graphics card for implementing alpha blending is supported, and the left and right rotation information, which is a real-time direction configured to be applied to the alpha blending input from the control unit 50, to a preset screen. In order to allow the user to check the divided navigation screen, the graphic card is controlled to be displayed through the display unit S1 in a translucent lighting method, which is an alpha blending process.

Accordingly, the present invention divides the navigation screen into a predetermined screen, and then displays a left turn and a right turn, which are driving directions of the vehicle, by turning on the translucent system, thereby making it possible to perform various operations in multiple ways. .

Next, the process of displaying the direction of navigation in the present embodiment having the above-described configuration will be described.

2 is a flowchart sequentially illustrating a navigation direction display method according to an exemplary embodiment of the present invention.

First, the GPS receiver 10 receiving the vehicle position information from the GPS satellite through the antenna (S201) provides the controller 50 with the received position information of the vehicle. In addition, the sensor detecting unit 20 configured as a gyro sensor and a speed sensor to detect the rotation angle and speed of the vehicle (S203) provides the detected rotation angle and speed to the controller 50.

At this time, the controller 50 determines whether destination information is input from the navigation input unit 40 (S205).

As a result of the determination (S205), when the destination information is input, the current position of the vehicle is calculated based on the rotation angle and the speed of the vehicle detected by the sensor detecting unit 20, and the vehicle is received by the GPS receiver 10. Compensating the cumulative error with the position information of the vehicle to calculate the final driving information of the vehicle, such as the current speed of the vehicle, as well as the driving speed and direction of travel (S207).

Next, the controller 50 extracts the left turn and the right turn information, which is the direction from the navigation input unit 40 to the input destination information, based on the calculated final driving information (S209) and is applied to the alpha blending by software in real time ( S211) is provided to the translucent display control unit 60.

As a result of the determination (S205), if the destination information is not input, the determination process is continuously performed until the destination information is input.

In the translucent display control unit 60 supporting a graphics card for implementing alpha blending, the left and right rotation information, which is a software direction configured to be applied to the alpha blending input from the control unit 50, is divided into predetermined screens (S213). Display (S215) through the display unit S1 in a semi-transparent lighting manner, which is an alpha blending process, on the graphics card so that the user can check the (divided and tri-divided) navigation screen (S215), for example, as shown in FIGS. 3A and 3B. In the case of dividing, the left side is controlled to be rotated to the left and the right is displayed as the right, and in the case of three-division, the left is controlled to be displayed as the right and the right to the left.

Here, the translucent lighting method is referred to as alpha blending technology (e.g., alpha blending technology, in computer graphics, each pixel has three color information of red, green, and blue, and sometimes there is an alpha channel as a fourth element. Control the display of other graphic information, such as adjusting the transparency.) The left and right turning information, which is the direction of the vehicle, is translucently implemented. In other words, alpha blending is used to have the effect of seeing the object behind the glass when there is glass in front of the object, and not seeing anything in between.

As described above, according to the present invention, by displaying the navigation direction in a semi-transparent lighting method, the display part of a small size can be easily used, and thus the reliability of the product can be greatly improved.
