摘要： An endoscope 2 has a CCD 9 incorporated in the distal part of an insertion unit 6 thereof. The sensitivity of the CCD 9 can be varied by applying a plurality of pulsating driving signals so as to change an electron multiplication rate. The endoscope 2 is connected to a processor 3 so that it can be disconnected freely. Information representing a type of endoscope stored in advance in a ROM 48 is transmitted to a controller 21 incorporated in the processor 3. The control means 21 uses a CCD sensitivity control means 12 to control the sensitivity of the CCD 9 according to the type of connected endoscope 2. Consequently, a view image of proper brightness can be produced irrespective of the type of endoscope 2.
摘要翻译：内窥镜2具有并入其插入单元6的远端部的CCD 9。可以通过施加多个脉动驱动信号来改变CCD 9的灵敏度，以改变电子倍增率。内窥镜2与处理器3连接，能够自由断开。表示预先存储在ROM48中的内窥镜的信息被传送到内置于处理器3中的控制器21.控制装置21使用CCD敏感度控制装置12根据所连接的类型来控制CCD 9的灵敏度内窥镜2.因此，无论内窥镜2的种类如何，都可以产生适当亮度的视野图像。

The endoscope 2 is connected to a processor 3 so that it can be disconnected freely.

The control means 21 uses a CCD sensitivity control means 12 to control the sensitivity of the CCD 9 according to the type of connected endoscope 2. In addition, an automatic gain control circuit supplementarily amplifies a signal output from the CCD 9 so that the level of the signal becomes a predetermined level. Consequently, a view image of proper brightness can be produced irrespective of the type of endoscope 2.

摘要： An endoscope includes a solid image-pickup device having an image area and an optical black area for performing photoelectric conversion and including a function of varying an amplification ratio, and a first signal clamp circuit clamps the analog output signal that is outputted from the solid image-pickup device to adjust into an input range of the analog signal processing circuit with an analog reference signal which is unaffected by a defective pixel in the optical black area. The clamped signal is processed to extract signal components which are photoelectrically converted by the analog signal processing circuit by the image area. The output signal from the analog signal processing circuit clamps the signal in the optical black area by using output signals of at least the number of pixels larger than the number of pixels in a horizontal direction in the optical black area by the second signal clamp circuit.
