Patent abstract
Assume that the position of a sun visor main body is adjusted by an occupant when incident light having the incident angle θ1 has entered a vehicle passenger compartment. Then, a straight line L1 is obtained that passes through the distal end position S1 of the moved sun visor main body and is inclined by the same angle as the incident angle θ1. At this time, the intersection between a straight line Y1, which passes through an eye position P0 of a average sized person and extends along the vertical direction of a vehicle, and the straight line L1 is estimated as an eye position P1 of the occupant. Thereafter, a light blocking control is performed in accordance with the estimated eye position P1.
