known functions and constructions may be omitted for increased clarity and conciseness . fig5 is a view provided to explain a concept of a special vehicle avm ( around view monitoring ) system according to an exemplary embodiment of the present disclosure . the special vehicle avm system according to the present exemplary embodiment divides a camera network and operates the divided camera networks as multiple networks . more specifically , as illustrated in fig5 , the avm system according to the present exemplary embodiment is constructed by 1 ) ‘ a front direction camera network ’ consisting of a front direction / left side camera 110 - 1 , front direction camera 110 - 2 , and front direction / right side camera 110 - 3 , and 2 ) ‘ a rear direction camera network ’ consisting of a rear direction / left side camera 110 - 4 , rear direction camera 110 - 5 , and rear direction / right side camera 110 - 6 . the front direction camera network and rear direction camera network are full duplex type ring network , that is , it is a separately divided network each of which is controlled by a different network controller . a ‘ front direction image ’ is created by the cameras 110 - 1 , 110 - 2 , and 110 - 3 configuring the front camera network . in addition , a ‘ rear direction image ’ is created by images of the cameras 110 - 4 , 110 - 5 , and 110 - 6 configuring the rear direction camera network . each of the front direction image and rear direction image is displayed on each display , or displayed on a divided screen in one display . fig6 illustrates a displayed result of the front direction image created by the images of the cameras 110 - 1 , 110 - 2 , and 110 - 3 forming the front direction camera network and of the rear direction image created by the images of the cameras 110 - 4 , 110 - 5 , and 110 - 6 forming the rear camera network . for a special vehicle avm system according to the present exemplary embodiment , a dynamic camera network may be configured . more specifically , it is possible to automatically change the cameras configuring the camera network according to the proceeding direction of the special vehicle . for example , in a case where a special vehicle goes forward or reverses , as illustrated in fig5 , a front direction camera network is constructed by the cameras 110 - 1 , 110 - 2 , and 110 - 3 provided in the front direction , and a rear camera network may be constructed by the cameras 110 - 4 , 110 - 5 , and 110 - 6 provided in the rear direction . on the other hand , in a case where the vehicle goes forward or reverses while turning left or right , as illustrated in fig7 , a left side camera network may be constructed by the cameras 110 - 1 and 110 - 4 provided in the left side and the front direction camera 110 - 2 , and a right camera network may be constructed by the cameras 110 - 3 and 110 - 6 provided in the right side and the right camera network . fig8 is an internal block diagram of a special vehicle avm system illustrated in fig5 . as illustrated in fig8 , the special vehicle avm system is equipped with cameras 110 - 1 to 110 - 6 , nic ( network interface card ) 120 , interface controller 130 , processor 140 , memory 150 , display 160 , and external interface 170 . cameras 110 - 1 to 110 - 6 photograph the front direction / left side , front direction , front direction / right side , rear direction / left side , rear direction and rear direction / right side of the special vehicle and creates an image . the nic 120 is equipped with an nc - 1 ( network controller - 1 ) 121 , nc - 2 122 , and multi port 123 . the multi port 123 is a switching element for selectively connecting the cameras 110 - 1 to 110 - 6 with nc - 1 121 and nc - 2 122 . when the vehicle goes straight or reverses , 1 ) nc - 1 121 constructs a front direction camera network with front direction / left side camera 110 - 1 , front direction camera 110 - 2 , and front direction / right side camera 11 - 3 and controls networking , while 2 ) nc - 2 122 constructs a rear direction camera network with rear direction / left side camera 110 - 4 , rear direction camera 110 - 5 , and rear direction / right side camera 110 - 6 and controls networking . this is already explained hereinabove with reference to fig5 . meanwhile , in a case where the vehicle goes straight or reverses while turning to the left or right , 1 ) nc - 1 121 constructs a front direction camera network with a front direction / left side camera 110 - 1 , front direction camera 110 - 2 , and front direction / right side camera 110 - 3 and controls networking , and 2 ) nc - 2 122 constructs a rear direction camera network with a rear direction / left side camera 110 - 4 , rear direction camera 110 - 5 , and rear direction / right side camera 110 - 6 and controls networking , and this is already explained hereinabove with reference to fig5 . meanwhile , in a case where the vehicle goes straight or reverses while turning left or right , 1 ) nc - 1 121 constructs a left side camera network with a front direction camera 110 - 2 , front direction / left side camera 110 - 1 and rear direction / left side camera 110 - 4 and controls networking , and 2 ) constructs a rear direction camera network with a front direction / right side camera 110 - 3 , rear direction / right side camera 110 - 6 , and rear direction camera 110 - 5 and controls networking , and thus is already explained hereinabove with reference to fig7 . the interface controller 130 transmits communication interface among nc - 1 121 , nc - 2 122 , processor 140 , display 160 , and external interface 170 . the processor 140 composes the images transmitted through nc - 1 121 and creates a front direction image or left image . in addition , the processor 140 composes the images transmitted through the nc - 2 122 and creates a rear direction image and right direction image . an image processing operation by the processor 140 is made separately . that is , the processor 140 divides the images transmitted through the nc - 1 121 and the images transmitted through the nc - 2 122 , and processes the images to be multiple images . the multiple image processing by the processor 140 alleviates complexity and load of image processing . that is because , image processing of composing six images and performing distortion correction is much more complex and has more load than making two image processing of performing distorting correction . the memory 150 provides storage space for the processor 140 to perform image processing . the display 160 is equipped with a display - 1 161 and display - 2 162 , which may be physically divided displays , or screens divided from one display . on display - 1 161 , an image created from the network constructed by nc - 1 121 is displayed , and on display - 2 162 , an image created from the network constructed by nc - 2 122 is displayed . the external interface 170 is an interface supporting communication connection with other networks inside the vehicle . fig9 is a view provided to explain a concept of a special vehicle avm system according to another exemplary embodiment of the present disclosure . the special vehicle avm system according to the present exemplary embodiment is different from the avm system illustrated in fig5 which photographs the same direction with one camera , in that it photographs the same direction with a plurality of cameras . more specifically , the avm system according to the present exemplary embodiment photographed the front direction in different directions with front direction / upper camera 110 - 7 and front direction / lower camera 110 - 8 , and photographed the rear direction in different directions with rear direction / upper camera 110 - 9 and rear direction / lower camera 110 - 10 , to prevent dead zones from occurring in low heights . the avm system illustrated in fig9 uses the avm system applied to a conventional general vehicle , but may change the location of the camera . when cameras are added in the side surface of the avm system illustrated in fig9 and thus the number of cameras exceeds four , as illustrated in fig5 , it is desirable to construct a multiple network . a number of examples have been described above . nevertheless , it will be understood that various modifications may be made . for example , suitable results may be achieved if the described techniques are performed in a different order and / or if components in a described system , architecture , device , or circuit are combined in a different manner and / or replaced or supplemented by other components or their equivalents . accordingly , other implementations are within the scope of the following claims .
