    • A light monitoring system, a glare prevention system, a method of monitoring glare and a vehicle 102 are provided. The light monitoring system comprises a camera system 114, a user's eye tracker 110 and an incident light calculator 124. The camera system 114 records at a camera location incident light from a light source. The user's eye tracker 110 determines a position of the user's eyes104. The incident light calculator 124 calculates perceived incident light by the user's eyes 104 and transforms the recorded incident light at the camera location into the perceived incident light at the position of the user's eyes. The perceived incident light may be used to estimate whether the user 106 perceives glare and this information may be used to control a dynamic light intensity filter such that the light originating from a too bright light source is dimmed.
    • 提供了光监视系统,防眩光系统,监视眩光的方法和车辆102。 光监视系统包括相机系统114,用户的眼睛跟踪器110和入射光计算器124.照相机系统114在照相机位置处记录来自光源的入射光。 用户的眼睛跟踪器110确定用户眼睛的位置104。 入射光计算器124计算由用户眼睛104感知的入射光,并将摄像机位置处记录的入射光转换成用户眼睛位置处的感知入射光。 感知的入射光可以用于估计用户106是否感知到眩光,并且该信息可以用于控制动态光强度滤波器,使得源自太亮光源的光变暗。

    • A light sensor is provided including a light transducer for accumulating charge in proportion to light incident thereon over an integration period; and a light-to-pulse circuit in communication with the light transducer, the light-to-pulse circuit operative to output a pulse having a pulse width based on the charge accumulated by the light transducer. The light-to-pulse circuit may include a one shot logic circuit that contributes to generation of the pulse. The light sensor may include an input/output pad, a capacitor provided at the input/output pad for blocking static electricity, an input low pass filter provided at the input/output pad for blocking electromagnetic interference, and/or a bandgap voltage reference circuit connected to a power source having a supply voltage level in a range of about 3.3V to about 5.0V, and for generating stable reference voltages throughout the supply voltage level range.
    • 提供了一种光传感器,包括:用于在积分周期内与入射到其上的光成比例地累积电荷的光转换器; 以及与所述光转换器通信的光对脉冲电路,所述光对脉冲电路用于输出基于所述光转换器累积的电荷具有脉冲宽度的脉冲。 光对脉冲电路可以包括有助于产生脉冲的单触发逻辑电路。 光传感器可以包括输入/​​输出焊盘,设置在输入/输出焊盘处用于阻断静电的电容器,设置在输入/输出焊盘处的用于阻挡电磁干扰的输入低通滤波器和/或带隙电压参考电路 连接到电源电压在约3.3V至约5.0V的范围内的电源,并用于在整个电源电压范围内产生稳定的参考电压。
