DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and various methods to which embodiments of the present invention are applied will be described in detail with reference to the drawings. The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

In FIG. 1, the situation in which the screen of the smart glasses is overlapped with the screen of the vehicle display device, and the problems occurring in such a situation will be described, and a method of avoiding screen overlap in FIGS. 2 and 3 will be described. Hereinafter, a configuration of a device for avoiding screen overlap based on the screen overlap avoiding method will be described.

FIG. 1 is a view for explaining screen superimposition of a screen of smart glasses and a vehicle display device according to an embodiment of the present invention.

The smart glasses 100 worn by the driver assume a state in which a connection is completed through a wireless communication system such as Bluetooth or WiFi with a wireless communication system connected to an AVN system or AVN system of a vehicle supporting a wireless connection function. Of course, it will be apparent to those of ordinary skill in the art that this is an exemplary and alternative to any component of the vehicle as long as the system is capable of providing safety related information related to the present invention.

The smart glasses 100 are wearable computers utilizing an augmented reality technology. They are equipped with a camera like a smart phone, have a photographing function, can utilize the wireless Internet, and can also perform SNS, text, navigation, and the like. The smart glasses 100 can be used as a display in a transparent screen installed on one side of two spectacle lenses.

Referring to FIG. 1, when the user wears the smart glasses 100, the display may be arranged to correspond to at least one of the left eye and the right eye, so as to provide images directly to the user's eyes. 1 illustrates that the display is located at a portion corresponding to the right eye so that an image can be output toward the user's right eye.

The display can project an image with the user's eyes using a prism. In addition, the prism may be formed in a light-transmissive manner so that the user can see the projected image and the general view of the front (the range that the user views through the eye) together, and the image output through the display is overlapped with the general view overlap.

A situation may occur in which the transparent display 200 installed on one lens of the smart glasses 100 overlaps the display 300 provided in the vehicle due to the overlapping characteristic.

Due to the overlapping of the displays, the driver can not receive the visual information output from the plurality of displays, and the driver may perform additional actions to avoid superimposition of the display, thereby causing a problem of forward-looking deviation.

Therefore, in order to solve such a problem, a method of avoiding screen superimposition of the screen of the smart glasses and the vehicle display device as one embodiment of the present invention will be described with reference to FIG. 2 and FIG.

2 is a flowchart for explaining a screen of smart glasses according to an embodiment of the present invention and a screen overlay avoiding method of a vehicle display device.

Referring to FIG. 2, a camera provided in the smart glasses captures a forward image of the smart glasses (S10).

The smart glasses determine whether a second display provided in the vehicle is detected from the image captured by the camera (S20). In other words, it is judged whether or not the second display is detected in the second area of a certain range of the images photographed by the camera.

The second area refers to the area corresponding to the first area covered by the first image provided by the first display of the smart glasses in the photographed image.

In other words, in order to determine whether the second display is detected in the photographed image, the smart glasses display the first area covered by the first image provided by the first display provided by the smart glasses from the viewpoint of the driver wearing the smart glasses . The smart glasses identify a second area corresponding to the first area in the photographed image, and detect the second display in the second area.

When the smart glasses detect the second display, the smart glasses determine a priority between the second image provided by the second display provided in the vehicle and the first image provided by the first display of the smart glasses (S30).

The priority criteria can be stored in a memory provided inside the smart glasses. The smart glasses can exchange information on the second image with the AVN system of the vehicle through a communication unit provided inside the smart glasses to determine the priority.

In other words, the smart glasses can receive information on the first image from the first display and the second image from the inside of the vehicle, and determine the priority of the information.

For example, if the second image of the second display provided on the vehicle contains driving information as an image for navigation, and the first image of the first display of the smart glasses is an SNS image, A higher priority can be given to the second image by assigning a ranking.

The smart glasses inactivate any one of the first display or the second display provided in the vehicle in consideration of the priority, or change at least one of the size and the position of the first image output to the smart glasses to avoid screen overlap (S40).

For example, if the second image has higher priority than the first image as the image including the traveling information, the smart glasses may deactivate the first display.

As another example, when the first image provided by the first display of smart glasses is a navigation image and the second image output by the second display provided inside the vehicle is a DMB image, the smart glasses deactivate the second display can do.

The smart glasses can send and receive signals to / from the AVN system of the vehicle through the communication unit to control whether or not the second display provided in the vehicle is activated.

In addition, instead of deactivating either the first display or the second display provided in the vehicle, the smart glasses selectively change at least one of the size and position of the first image in consideration of the priority, can do.

In order for the smart glasses to change at least one of the size and position of the first image, the smart glasses receive the driver's eye position information or the smart glasses position information collected through the internal sensor of the vehicle from the AVN system, The visual range can be calculated, and at least one of the size and the position can be changed in consideration of the visual range.

For example, the in-vehicle sensor can be a camera installed in a room mirror of a vehicle, and can capture the driver's eye position or the position of the smart glasses to calculate the driver's visual range. The smart glasses receive the information on the calculated field of view from the AVN system of the vehicle and can control the first display to output the first image in an area that is not overlapped with the second display in consideration of the calculated field of view have.

FIG. 3 is a flowchart for explaining step S20 of detecting a second display provided in the vehicle of FIG. 2 in more detail.

Since the camera provided in the smart glasses is located adjacent to the eyes, a scene viewed by the user can be acquired as an image.

The smart glasses recognize whether flickering occurs in the image to detect a second display provided in the vehicle in the image taken by the camera.

The flickering phenomenon refers to a periodic change in luminosity such as a screen of a display device or a flickering of a fluorescent lamp. In other words, flicker refers to flickering of an image appearing on the screen, and flickering occurs when the eye does not recognize a continuous image due to a slow projection speed. Generally, when the flickering is 60 (Hz) or more, it is determined that the image is outputted from the display device.

The smart glasses can detect the display provided in the vehicle whether or not the camera exceeds the predetermined threshold period (e.g., 60 (Hz)) by calculating the flickering period of the photographed image.

However, in order to identify the display provided in the vehicle using only the period of flickering, it is necessary to identify whether or not flickering occurs in all areas of the image photographed by the camera.

Accordingly, in an embodiment of the present invention, a rectangle shape, which is a frame shape of a general display, is first recognized among a second area included in the image photographed by the camera (S21), and the ratio of the recognized rectangle is set to a ratio (S22), it is detected whether flickering has occurred only for the rectangular shape estimated by the display (S23).

The ratio of the preset display means a ratio estimated to be a general display screen. For example, the ratio is 4: 3, 16: 9, 16:10, 21: 9 and so on.

For example, when the smart glasses recognize a rectangular shape in the captured image, and the ratio of the recognized rectangular shape is 4: 3, it is only necessary to identify whether flickering occurs in the recognized rectangular shape.

4 is a block diagram for explaining a screen of smart glasses according to an embodiment of the present invention and a screen overlap avoiding apparatus of a vehicle display apparatus.

4, the screen of the smart glasses and the screen overlap prevention device 400 of the vehicle display device include a first display 410, a camera 420, a control unit 430, a communication unit 440, and a memory 450 .

The components shown in Fig. 4 are not essential, so that a screen overlap avoiding apparatus having more or fewer components can be implemented.

Hereinafter, the components will be described in detail.

The first display 410 may be implemented as a head mounted display (HMD). The HMD type refers to a display method that is mounted on a head and displays an image directly in front of the user's eyes. When the user wears smart glasses, the first display 410 may be arranged to correspond to at least one of the left eye and the right eye so as to provide images directly in front of the user's eyes.

The first display 410 may project an image to the user's eye using a prism. Further, the prism may be formed to be transmissive so that the user can view the projected image and the general view of the front (the range that the user views through the eyes) together.

The camera 420 is disposed adjacent to at least one of the left eye and the right eye, and captures a forward image. Since the camera 420 is positioned adjacent to the eye, the camera 420 can acquire a scene viewed by the user as an image.

The control unit 430 may perform data processing and calculation to control the screen overlap avoiding apparatus.

In one embodiment, the control unit 430 detects the second display of the photographed image in the second area corresponding to the first area covered by the first image, and the second display detects The priority between the second image and the first image provided by the second display provided in the vehicle is determined.

The control unit 430 deactivates either the first display or the second display in consideration of the determined priority, or controls the display unit so that at least one of the size and the position of the first image is changed so that the first image does not overlap the second image. 1 display can be controlled.

The communication unit 440 exchanges signals and data for controlling screen overlap prevention between the smart glasses and the AVN system of the vehicle.

In one embodiment, the communication unit 440 delivers a signal to the AVN system that controls whether to activate the second display.

The memory 240 stores a predetermined program code for controlling the overall operation of the screen superposition avoiding apparatus 400 and a space for storing data input / output when the operation is performed by the program code and / And is provided in the form of an EEPROM (Electrically Erasable and Programmable Read Only Memory), an FM (Flash Memory), a hard disk drive, or the like.

In one embodiment, the memory 240 may store the threshold period value of flickering and may store a reference of priority.
