The invention relates to a light device for a motor vehicle, comprising a matrix light source which performs a light function within the motor vehicle. The same source is used, together with a photodiode, to estimate the flight time of captured light pulses which are initially generated by the matrix source. It is thus possible to detect objects and/or gestures using light in the visible spectrum, and without using specific pulse sources provided for that purpose.
本发明提出了一种用于机动车辆的照明装置,该照明装置包括在机动车辆内执行照明功能的矩阵光源。使用同一光源和光电二极管一起来估计由矩阵源最初生成的捕获的光脉冲的飞行时间。可以使用可见光谱的光来检测物体和/或姿势,而不必使用专用于此目的的特定脉冲源。
