    摘要： To provide a first memory for storing an odd field data, a second memory for storing an even field data acquired in an NTSC system, a third memory for storing the same video data stored in the first and second memories, and a TV standard conversion circuit. For the data in a period for which a writing of a next data overtakes reading of the data from the first memory or the second memory, a writing into the third memory is inhibited, and the data is read from the third memory, whereby the signal of the NTSC system is converted into the signal of a PAL system. In this manner, an excellent video is displayed on a PAL monitor without any the bar noise.

    摘要： A connector guide structure for electronic endoscope systems capable of efficiently eliminating high-frequency noises which are allowed by a connector guide functioning as an antenna to mix by way of sheath members and a console. The connector guide structure comprises a connector guide for connecting a connector disposed on an electronic endoscope to a main unit, and noise eliminating capacitors are connected between the connector guide and a console of the main unit. A capacitor for eliminating noises produced by a radio knife and a plurality of capacitors for eliminating noises produced by clock-frequency signals are used as the capacitors. Feet of the capacitors are directly connected within an interval of 4 mm to 20 mm which is reserved between the connector guide and the console. Accordingly, the connector guide structure is capable of favorably eliminating not only the noises produced by the radio knife but also the noises produced by providing clock-frequency signals.

    摘要： A shielding structure of an electronic endoscope apparatus which can sufficiently remove noise even when an electric cautery is used. A signal transmission cable which connects a charge coupled device disposed at the end portion of an electronic endoscope to a processor unit is electrically shielded by a double shield composed by an inner shield and an outer shield. The inner shield is connected to the ground in a light source connector and the outer shield is connected to the frame ground of the processor unit through a capacitor. The outer shield is further connected to a shielding member provided around the charge coupled device and a patient ground to which an electrode piece of an electric cautery is connected. Noise is greatly removed, so that the picture quality is improved.
