Patent ID: 8102421

Claim:
An image processing device for a driver's vehicle comprising: means for receiving monitored image data of front objects that exist in front of the driver's vehicle; means for receiving position information of the front objects which are obtained from a wave transmitted toward the front area in front of the driver's vehicle and reflected by the front objects; means for determining a processing area including a front target object in the front objects in the monitored image data based on the position information; and means for judging whether or not the front target object is a three-dimensional object based on edges detected in the image data in the processing area determined by the determining means, wherein the judging means judges the front target object is a three-dimensional object when at least one of following conditions (a) and (b) is satisfied: (a) a maximum value is not less than a predetermined maximum threshold value, where the maximum value is the maximum value in vertical column edge values that is obtained by summing vertical edge values per each column in the image data in the processing area; and (b) an average value is not less than a predetermined average threshold value, where the average value is the average value of the vertical column edge values that is obtained by summing the vertical edge values per each column in the image data in the processing area.
