The touch input receiving unit 200 may receive a touch signal of the display device 600 included in the vehicle. That is, the touch input receiving unit 200 may differently receive a touch signal according to the number of times of touch of the display device 600 by a user, a touch method, and a touch area. According to the present exemplary embodiment, the touch signal may include four types of touch signals, that is, a first touch signal, a second touch signal, a third touch signal, and a fourth touch signal. This will be described in detail below.
The control unit 300 may control an output effect of image data around the vehicle output to the display device 600 according to the gear information transmitted from the travel information receiving unit 100 and the touch signal transmitted from the touch input receiving unit 200.
The control unit 300 may include a view change effect selection unit 310 selecting an output effect of the image data, and a view change unit 320 applying an output effect to image data.
Here, the view change effect selection unit 310 may receive a touch signal transmitted from the touch input receiving unit 200 and analyze the touch signal, and select an output effect of image data corresponding to the touch signal.

Referring to FIG. 6, a part of image data output on the around view area 610 may be enlarged and output according to a touch signal on the crop-view area 620, and an outputting screen may be controlled according to the fourth touch signal. More particularly, when a user touches a part of the crop-view area 620 one time, and then pushes the touched part in one direction among the up, down, left, and right directions, the crop-view area 620 may rotate in a rotation cube type to output image data.
An icon, which is capable of selecting an output angle of the image data output on the crop-view area 620, may be generated in the button area 630.
Hereinafter, a method of controlling the AVM system according to an exemplary embodiment of the present invention will be described.
First, a user activates the AVM system.
When the AVM system is activated, the travel information receiving unit 100 first receives gear information from the transmission 500 of the vehicle. The travel information receiving unit 100 check whether the vehicle drives or reverses, and when the gear information indicates that the vehicle drives, the travel information receiving unit 100 outputs image data of the front camera 400 of the vehicle, and when the gear information indicates that the vehicle reverses, the travel information receiving unit 100 outputs image data of the rear camera 400 of the vehicle.
When the travel information receiving unit 100 receives the gear information, and then the user inputs touch signal through the display device 600, the touch input receiving unit 200 receives a touch signal.
After the travel information receiving unit 100 receives the gear information and the touch signal, the view change effect selection unit 310 analyzes the received touch signal.
Here, the method of analyzing the touch signal will be described below.
First, the view change effect selection unit 310 determines whether the touch is operated with one or two fingers through position coordinate counting of the touch signal.
When the touch is operated with one finger, the view change effect selection unit 310 stores a time, at which the touch signal is input, and touch coordinates. When the corresponding touch signal is terminated within time t1 after the first touch signal is input, and the second touch signal is not input within time t2, the view change effect selection unit 310 recognizes the touch signal as the first touch signal, and transmits the touch coordinates and an output effect of the image data to the view change unit 320.
When the corresponding touch signal is terminated within time t1 after the first touch signal is input, and a second touch signal is input within time t2, the view change effect selection unit 310 recognizes the touch signal as the second touch signal, and transmits the touch coordinates and an output effect of the image data to the view change unit 320.
When the corresponding touch signal is maintained and the touch coordinates are changed within time t1 after the first touch signal is input, the view change effect selection unit 310 recognizes the touch signal as a fourth touch signal, and transmits the touch coordinates and an output effect of the image data to the view change unit 320.
When the touch is operated with two fingers, the view change effect selection unit 310 stores a time, at which the touch signal is input, and touch coordinates. When it is assumed that a distance between touch coordinates of the two fingers at time t2 is Lt1, and a distance between touch coordinates of the two fingers at time t3 is Lt2, when Lt2−Lt1 is larger than 0, the view change effect selection unit 310 recognizes the touch as a zoom-in operation, and when Lt2−Lt1 is smaller than 0, the view change effect selection unit 310 recognizes the touch as a zoom-out operation, and transmits the touch coordinates and an output effect of the image data to the view change unit 320.
When the view change effect selection unit 310 analyzes the received touch signal and transmits the output effect of the image data to the view change unit 320, the view change unit 320 applies the output effect to the image data and then outputs the image data on the display device 600.
According to the AVM system and the method of controlling the same according to the exemplary embodiment of the present invention including the aforementioned configuration, it is possible to display a customized image based on a touch input of a user, and intuitively display a correlation between views by applying various animation effects when a view is changed, thereby improving convenience for a user.
In the AVM system and the method of controlling the same according to the exemplary embodiment, the configuration and method of the exemplary embodiments as described above may not be limited, but the exemplary embodiments may be configured by selectively combining all or a part of each embodiment such that various modifications may be made.
While the exemplary embodiment of the present invention has been illustrated and described above, the present invention is not limited to the aforementioned specific exemplary embodiment, various modifications may be made by a person with ordinary skill in the art to which the present invention pertains without departing from the subject matters of the present invention that are claimed in the claims, and these modifications should not be appreciated individually from the technical spirit or prospect of the present invention.
