    摘要: Using an endoscope system, a surgeon A holds an endoscope with a TV camera (hereinafter, an endoscope) and a therapeutic appliance such as forceps and carries out a surgical procedure while viewing a first monitor. A surgeon B holds a therapeutic appliance such as forceps and carries out the surgical procedure while viewing a second monitor. A video signal sent from the TV camera of the endoscope is fed to and processed by an image processing apparatus, and displayed on each of the first and second monitors. The image processing apparatus transfers the video signal sent from the endoscope to each of an image inverting circuit and a selector switch. The image inverting circuit inverts an image (laterally (to produce a mirror image), vertically, or vertically and laterally (180°)), and supplies a processed video signal to the selector switch. The selector switch selects a video signal to be supplied to each of the first and second monitors, which are display units, in response to a control signal sent from a selector. The contents of processing to be performed by the image inverting circuit and the video signal to be selected by the selector are designated using setting switches on an operation panel.

    摘要: An endoscope signal processing apparatus has a first video signal generating circuit and a second video signal generating circuit which respectively generate a first video signal and a second video signal offering different resolutions depending on a first image capturing device and a second image capturing device respectively which are mounted in an endoscope removably connected to an endoscope connecting portion. The first and second video signals can be selectively output to an exterior through a common video signal output connector.

    摘要: An imaging apparatus having an imaging device for imaging an object in cooperation with an endoscope is connected to a video processing unit for producing a standard video signal so that it can be disconnected freely. A signal delay occurs over a signal line linking the imaging device and the video processing unit. For this reason, a timing generator and a phase adjustment circuit are incorporated in the imaging apparatus. The timing generator generates driving signals used to drive the imaging device, and the phase adjustment circuit adjusts the phases of the driving signals so that an output signal of the imaging device will be input to the video processing unit according to predetermined timing. Even when the signal line has a different length from any other or the imaging device offers a different number of pixels from any other, the difference can be readily coped with owing to the imaging apparatus. This leads to alleviation of a load incurred by the video processing unit.

    摘要: In an endoscopic apparatus, when the dynamic range expansion on/off switch is turned on, a CPU changes a switch from one contact over to another. Red, green, and blue digital signals sent from a knee and gamma circuit are output to respective dynamic range expanding circuits. Thus, the dynamic ranges for the digital signals are expanded. On the other hand, when the CPU changes another switch from one contact over to the other, a light adjustment signal output from an operational amplifier is then driven to a level causing a diaphragm in a light source unit to open further. Consequently, an increased amount of illumination light is supplied to the incident end of a light guide running through an endoscope. Thus, when a dynamic range is expanded, a halation effect will not occur in imaging of an object located at a point near the distal end of the endoscope. Moreover, insufficiency of illumination light will not occur in the imaging of an object located at a point far from the endoscope distal end. The dynamic range can therefore be expanded efficiently. An endoscopic image of the interior of a body cavity can be viewed with the body cavity set to a desired brightness level all points ranging from a near point to a far point within the body cavity.
