    • A plurality of lighting units are positioned forwardly of the driver seat in the cabin of a vehicle for applying infrared radiations in respective directions to the vehicle driver seated on the driver seat. The intensities of the emitted infrared radiations are controlled according to respective basic controlled variables depending on the illuminance in the vehicle cabin. The position and orientation of the face of the vehicle driver are recognized from an image captured of the vehicle driver by an imaging device, and the basic controlled variables are corrected according to the recognized position and orientation, thereby adjusting the intensities of the infrared radiations emitted from the lighting units and a balance of the infrared radiations emitted from the lighting units. Thereafter, the illuminance in the vehicle cabin and the recognized position and orientation change, then corrective coefficients for the basic controlled variables are updated depending on the changes.
    • 多个照明单元位于车辆舱内的驾驶员座椅的前方,用于向坐在驾驶员座椅上的车辆驾驶员在相应方向上施加红外辐射。 发射的红外辐射的强度根据相应的基本控制的变量来控制,这取决于车厢内的照度。 通过成像装置从车辆驾驶员拍摄的图像识别车辆驾驶员的面部的位置和姿态,并且根据识别的位置和方向来校正基本受控变量,由此调整发射的红外辐射的强度 从照明单元和从照明单元发射的红外辐射的平衡。 此后,车厢中的照度和识别的位置和方向改变,然后根据变化更新基本受控变量的校正系数。
