14D , the vehicle driving assistance apparatus 100 may detect that the oncoming vehicle 1410 is located in the third area. In this case, the processor 280 of the vehicle lamp 200 may control so that all lights generated by the third lamp module 300 - 3 corresponding to the third region are not emitted toward the opposite vehicle 1410 . That is, the processor 280 of the vehicle lamp 200 controls the third shutter 255 - 3 disposed in front of the third lamp module to be switched to the first state, and the third lamp module 300 - 3 irradiates it. You can block the light from being emitted or allow only a portion of the light to be emitted.

14E , the vehicle driving assistance apparatus 100 may detect that the oncoming vehicle 1410 is located in the fourth area. In this case, the processor 280 of the vehicle lamp 200 may control so that all lights generated by the fourth lamp module 300 - 4 corresponding to the fourth region are not emitted toward the opposite vehicle 1410 . That is, the processor 280 of the vehicle lamp 200 controls the fourth shutter 255 - 4 disposed in front of the fourth lamp module to be switched to the first state, and is irradiated from the fourth lamp module 300 - 4 You can block the light from being emitted or allow only a portion of the light to be emitted.

The present invention described above can be implemented as computer-readable codes on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (eg, transmission over the Internet) that is implemented in the form of. Also, the computer may include a processor 270 or a controller 770 . Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
