1. An act-of-looking-aside determination device comprising:
a line-of-sight direction detector that detects a line-of-sight direction of a driver;
an act-of-looking-aside determiner that determines that the driver is looking aside when the line-of-sight direction detected by the line-of-sight direction detector deviates from a predetermined determination reference range;
a curve detector that detects presence or absence of a curve in front of an own vehicle within a predetermined distance from the own vehicle, and detects a curve direction of the curve, and outputs a detection result;
a surrounding information acquirer that acquires surrounding information of the own vehicle;
an other-vehicle detector that detects, based on the surrounding information of the own vehicle, presence or absence of an other vehicle in a lane that is adjacent, in a direction opposite to the curve direction detected by the curve detector, to an own lane where the own vehicle travels while the own vehicle is traveling around the curve;
a determination reference range changer that, when the own vehicle enters the curve, changes the determination reference range in the act-of-looking-aside determiner by a predetermined angle in the curve direction detected by the curve detector; and
a relative direction acquirer that acquires, by an arithmetic operation, relative direction information indicating a relative direction of the other vehicle as viewed from the own vehicle, wherein
when the line-of-sight direction detected by the line-of-sight direction detector is within a predetermined range from the relative direction of the other vehicle acquired by the relative direction acquirer, the act-of-looking-aside determiner does not determine that the driver is looking aside even when the line-of-sight direction is out of the determination reference range.
