    • A method of providing active illumination during biometry that utilizes pulsed lighting synchronized to frame acquisition. Two distinct illumination modalities are provided: the first maximizes the quality of images captured by the imaging system, and the second minimizes the overall illumination perceived by the user in combination with the first. The two modalities are provided substantially simultaneously. The first modality always includes a set of pulses synchronized with frame acquisition. The second modality may be either a second set of pulses not synchronized with frame acquisition or constant background illumination. The two modalities may be generated by two separate sources of illumination or by the same single illumination source. Adding the second modality to the first reduces user discomfort and the chances of an epileptic response as compared to using the first modality alone. The two modalities may have different wavelengths, pulse durations, or intensities.
    • 一种在生物测量期间提供有源照明的方法,其利用与帧采集同步的脉冲照明。 提供了两种不同的照明模式:第一最大化由成像系统拍摄的图像的质量,第二最小化用户结合第一图像感觉到的整体照明。 这两种方式基本同时提供。 第一种模式总是包含与帧采集同步的一组脉冲。 第二模式可以是与帧获取或恒定背景照明不同步的第二组脉冲。 两种模式可以由两个独立的照明源或相同的单一照明源产生。 与第一种模式相比,将第二种模式添加到第一种模式可减少用户不适和癫痫反应的可能性。 这两种方式可能具有不同的波长,脉冲持续时间或强度。

    • In a process in which a current is supplied from a switching regulator to multi-chip LEDs, the forward voltages of the LEDs are respectively detected in forward detecting circuits. The detected values are sent to a microcomputer. In the microcomputer, detected values when the multi-chip LEDs are initially turned on are stored as initial values. A first abnormality deciding value is set from the initial value. The detected values are sequentially stored as updated values. Second abnormality deciding values having conditions stricter than those of the first abnormality deciding value are sequentially set in accordance with the stored updated value. A read value is compared with the first abnormality deciding value or the read value is compared with the second abnormality deciding value to decide whether or not the abnormality of the LEDs is present. When it is decided that the LEDs are abnormal, an LED is turned on to inform a driver of the presence of the abnormality.
    • 在从开关调节器向多芯片LED提供电流的过程中,在正向检测电路中分别检测LED的正向电压。 检测到的值被发送到微型计算机。 在微型计算机中,当多芯片LED最初被接通时的检测值被存储为初始值。 从初始值设定第一异常判定值。 检测到的值被依次存储为更新值。 根据存储的更新值依次设定具有比第一异常判定值更严格的条件的第二异常判定值。 将读取值与第一异常判定值进行比较,或者将读取值与第二异常判定值进行比较,以判定是否存在LED的异常。 当判定LED异常时,LED点亮,通知驾驶员异常的存在。
