Claim:
1. An around view monitoring (AVM) apparatus, comprising: a plurality of cameras which is mounted on a vehicle; a video composing unit which receives a plurality of videos from the plurality of cameras and composes the plurality of videos to generate an around view video; a brightness correcting unit which receives the around view video and corrects the brightness of the around view video based on an average brightness value and a variation of the brightness values for every region which is included in the around view video and outputs the around view video whose brightness is corrected; and a video display unit which displays the around view video whose brightness is corrected, wherein the brightness correcting unit includes: a measuring unit which measures an average brightness value and a variance of the brightness values of an upper region of a boundary and a lower region of the boundary obtained by composing the plurality of videos in the around view video; a calculating unit which calculates a corrected brightness value of the around view video by a first calculating method or a second calculating method, using the average brightness value and the variance of the brightness values; and an applying unit which applies the calculated corrected brightness value to the around view video, wherein the applying unit applies an accumulated average value of a plurality of corrected brightness values which is calculated by the calculating unit to the around view video.
