To provide a variable light distribution headlight that can improve operability.SOLUTION: A variable light distribution headlight 1 is configured to vary a portion of high beam light distribution to suppress dazzlement to a surrounding. The variable light distribution headlight 1 comprises determining means 20 that detects whether or not there is other vehicle from video data and determines whether a position of the vehicle overlaps with the high beam light distribution, and light distribution control means 31 that, when the determining means 20 determines that the position overlaps with the light distribution, varies the high beam light distribution in an area where the position overlaps with the distribution. Further, the determining means 20, when the position of the other vehicle overlaps with the high beam light distribution, determines whether other vehicle is stopped or not and whether other vehicle is emitting flashing light or not. The light distribution control means 31, when other vehicle is not stopped or when other vehicle is not emitting flashing light, controls the overlapping area into a light-blocking condition, and when other vehicle is stopped and when other vehicle is emitting flashing light, controls the overlapping area into a light extinction condition.SELECTED DRAWING: Figure 1
【課題】運転性の向上を図ることが可能な配光可変型前照灯を提供する。【解決手段】配光可変型前照灯1は、ハイビーム配光の一部を変化させて周囲への眩惑を抑制するものである。この配光可変型前照灯1は、映像データから他車両の存在有無を検出し、その位置がハイビーム配光と重複するかを判定する判定手段20と、判定手段20によって重複すると判定された場合に、重複領域におけるハイビーム配光を変化させる配光制御手段31とを備えている。また、判定手段20は、他車両の位置とハイビーム配光とが重複する場合に、当該他車両が停車しているか、及び、当該他車両が点滅光を発光しているかを判定し、配光制御手段31は、他車両が停車しておらず又は点滅光を発光していない場合には、重複領域を遮光状態に制御し、他車両が停車し且つ点滅光を発光している場合には、重複領域を減光状態に制御する。【選択図】図1
