Abstract
A complex marking determining device includes a brightness state calculating portion configured to calculate a lane marking representative value indicative of a brightness state of a plurality of pixels that make up a lane marking display region, and calculate a road surface representative value indicative of a brightness state of a plurality of pixels that make up the road surface display region; and a complex marking determining portion configured to determine that the lane marking is a complex marking at least when a degree of deviation between the lane marking representative value and the road surface representative value is equal to or greater than a first threshold value.
