    摘要： A plurality of photoconductive cells are each formed on an insulating substrate to extend in a straight line. The photoconductive cells are divided into m groups, each consisting of n cells, which is connected at one end to a common electrode, and corresponding ones of the photoconductive cells of the m groups are connected to individual select electrodes, respectively. By turning ON group select switches in a sequential order, the common electrodes are connected to a power source one at a time and, by sequentially turning ON individual select switches, the individual select electrodes are connected to a load one at a time. The common electrodes are grounded via grounding switches which operate reversely from select switches connected to the common electrodes. The individual select electrodes are grounded via grounding switches which operate reversely from select switches connected to the individual select electrodes. The resistance value of the load is selected sufficiently smaller than the composite resistance value of the photoconductive cells connected in parallel to the load when one of the group select switches and one of the individual select switches are both in the ON state.

    摘要翻译： 在绝缘基板上分别形成多个光电导元件，以直线延伸。 光导电池分为m组，每组由n个电池组成，n个电池的一端连接到公共电极，m组的相应的光导电池分别连接到各个选择电极。 通过按顺序接通组选择开关，公共电极一次连接到电源，并且通过依次接通各个选择开关，各个选择电极一次连接到一个负载。 公共电极通过接地开关接地，这些开关与连接到公共电极的选择开关相反地工作。 各个选择电极通过接地开关接地，接地开关与连接到各个选择电极的选择开关相反地工作。 当组选择开关和单个选择开关中的一个都处于接通状态时，负载的电阻值被选择得足够小于与负载并联连接的光电元件的复合电阻值。

    摘要： A/D conversion of a video scan signal having a substantially constant shading profile. Waveform of a blank or white scan signal is decomposed into gently varying component and steeply changing component superposed on the former. These components are detected by separately provided A/D converters. The gently varying component can be detected by a low speed A/D converter. By adopting the level of the gently varying component as a reference level, the steeply changing components can be detected with a reduced number of bits at an improved precision.
