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： With an electronic endoscope, a wide band video signal is output to connected instruments without giving electric shocks to a body even when the connected instruments are not insulated. The video signal V is converted to differential signals V1, V2 by a differential amp 31 and input to buffers 42, 43 via capacitors 32, 33. The clamp signal CP generated by the clamp signal output means 44 is input to the end terminals of the switches SW1, SW2 via the photocoupler 46. The differential signals V1, V2 undergo pulse clamping in the buffers 42, 43 and the DC components are restored. The video signal restoring portion 49 restores the video signal V on the basis of the differential signals V1, V2 having undergone DC restoration and outputs the video signals to the connected instruments.

摘要： A light source device for an endoscope is capable of selecting a reading method between a method utilizing a light shading period and a method doing without a light shading period. It is possible to adopt both the new reading method and the conventional reading method. A rotary shutter is composed of, for example, a disk with a light passing portion for securing a light source path and a light shading portion formed on the outer peripheral portion, and a DC motor rotates and stops the rotary shutter. When the electronic endoscope apparatus to which the light source device is applied is of an all-pixels reading type, the rotation mode in which light is output during a predetermined light shading period at intervals of 1/30 sec is set. When the light source device is applied to a conventional electronic endoscope apparatus, for example, of a pixel mixture signal reading type system, the stop mode in which the illuminating light is not shaded is set. The reading system adopted by the electronic endoscope apparatus is judged by an ID discriminator, and the rotary shutter is stopped at a predetermined position by a stop controller in the stop mode.

摘要： An electronic endoscope apparatus uses a circuit board having a cavity for achieving a predetermined electrical insulation. The apparatus includes a patient circuit on the side of the electronic endoscope, an output circuit for performing a predetermined image processing, and an isolation device for maintaining a predetermined dielectric strength between the two circuits; and the cavity is formed on one circuit board where the isolation device is disposed extending over the cavity. Further, the cavity is extended outward by a predetermined length so that signal lines on the two sides to be connected to the isolation device are positioned with a distance from each other on the circuit board by which a predetermined dielectric strength may be maintained. Thereby, current detouring through the circuit board may be effectively prevented and it is possible to isolate the patient circuit and the output circuit from each other also on the circuit board.

摘要： With a device that connects a processor device to electronic endoscopes having CCDs with different numbers of pixels, for example, 410, 270, or 190 thousand pixels mounted thereon, all the CCDs are driven at a frequency corresponding to 410 thousand pixels. Further, an information amount converting circuit enlarges an image obtained by the CCD with 270 or 190 thousand pixels in a horizontal direction and a vertical direction by using pixel interpolation. That is, data on a pixel to be interpolated is calculated by averaging pixels around this pixel, and enlarged binary data on this target pixel is obtained. A weighting factor is applied to this binary data, and the resultant data is added to the target pixel data. This process forms an image with an aspect ratio of 4:3.
