    • A comb-shaped piezoelectric unit, such as may be used for a mechanical signal source or in a display device for displaying raised letters for reading by blind persons. The piezoelectric unit includes a plurality of strip-shaped drive members extending from a common base part, a first metal electrode layer on each of the drive members with the first metal electrode layers among the drive members being insulated from one another, and a common metal electrode layer formed on the other side of the drive members, connected commonly to all drive members. To construct a display device for the blind, pins are attached to the free ends of each of the drive members, the pins being protrudable through respective holes in a rigid plate when the corresponding drive members are actuated by applying a voltage thereto.

    • An automatic exposure (AE) sensor includes a line-selecting circuit for line selection between horizontal lines and vertical lines, in addition to components of a typical AE sensor. The line-selecting circuit temporally filters a SYNC pulse for notifying a subsequent circuit about a pulse timing of an imaging signal to select a line to be read out and to cause the subsequent circuit to change an active pixel region. The number of selected lines is determined by an external input. The active pixel region is reduced when the AE sensor is incorporated in a device having a low performance CPU, thereby reducing load on the CPU. The active pixel region is increased when the AE sensor is incorporated in a device having a high performance CPU, thereby effectively using the CPU performance to achieve higher density control.
    • 自动曝光(AE)传感器除了典型的AE传感器的部件之外还包括用于水平线和垂直线之间的线选择的线选择电路。 线路选择电路对SYNC脉冲进行时间滤波,以通知后续电路关于成像信号的脉冲定时,以选择要读出的行,并使随后的电路改变有源像素区域。 所选行的数量由外部输入决定。 当AE传感器被并入具有低性能CPU的设备中时,有源像素区域减小,从而减少CPU上的负载。 当AE传感器被并入具有高性能CPU的设备中时,有源像素区域增加,从而有效地利用CPU性能来实现更高密度的控制。
