    • A power supply unit capable of varying power supplied to a light source at timings determined by synchronization signals is provided. The power supply unit comprises an interface that receives a plurality of types of synchronization signals with different pulse widths and a control unit that changes a setting of output power supplied by the power supply unit in accordance with the pulse widths of the plurality of types of synchronization signals. The control unit includes obtaining a standard time interval from a cycle of a standard type of synchronization signal that has a longest pulse width, parsing for determining type of each synchronization signal, redefining supply power values corresponding to respective types of synchronization signals, and changing the setting of output power of the power supply unit to a supply power value corresponding to a type of the synchronization signal.
    • 提供一种能够在由同步信号确定的定时改变供给光源的功率的电源单元。 电源单元包括接收具有不同脉冲宽度的多种类型的同步信号的接口和控制单元,其根据多种类型的同步的脉冲宽度改变由电源单元提供的输出功率的设置 信号。 控制单元包括从具有最长脉冲宽度的标准类型的同步信号的周期获得标准时间间隔,用于确定每个同步信号的类型的解析,重新定义对应于各种类型的同步信号的电源功率值,以及改变 将电源单元的输出功率设置为与同步信号的类型相对应的电源功率值。
