A system controller configured to centrally control control target devices used in surgery includes a communicating device capable of communicating with a plurality of control target devices, an extraction condition memory capable of storing extraction conditions, and a processor including hardware. The processor detects an abnormal state of connected control target devices. The processor performs recording processing for recording operation information relating to operation on the control target devices as log data into a predetermined storage apparatus. When a device abnormality detecting section detects an abnormal state, the processor extracts relevant information related to the abnormal state from log data.

The system controller includes a discriminating section and a control section configured to perform control to display, when an endoscopic image is displayed on the operating field monitor, a voice operation main screen for instructing operation of a controlled apparatuses and the endoscopic image on the operating field monitor and display, when the endoscopic image is not displayed on the operating field monitor, a voice operation screen for performing a check of operation states of the controlled apparatuses and an operation instruction of the controlled apparatuses on the operating field monitor.

A camera control unit for processing a signal output from an imaging device incorporated in an endoscope is provided with an analog video signal output terminal through which a video signal is output to a monitor, and a digital video signal output terminal to which a still image-specific or motion picture-specific expansion unit is coupled in a freely detachable manner. By handling a release switch, a still image or motion picture can be recorded digitally. Even when the recorded image data is edited or subjected to any other processing, deterioration of image quality can be prevented. An imaging system having these advantages can be realized on a small scale.

Endoscopic imaging system in which still image-specific or motion picture-specific expansion unit can be coupled to digital video output terminal in freely uncoupled manner

In an endoscopic imaging system, a signal representing an object image produced by a scope and projected by a camera head is processed by a CCU and displayed as an endoscopic image on a TV monitor. The object image is stored as digital image data on a memory in the CCU, read as image data of a still image, and recorded on a PC card mounted in a PC card slot. The PC card slot is formed in the front panel or the like of the CCU. A lid member or the like functioning as an anti-liquid invasion member and shield can be located at an opening of the slot.

An object is imaged continuously during a first exposure time and a second exposure time shorter than the first exposure time. Weights, one of which decreases monotonously and the other of which increases monotonously, are applied to first and second resultant image signals under the condition that the sum of the weights is 1. The first and second image signals that have been weighted are added up, thus producing a synthetic picture signal. When a luminance level is low, the ratio of the first image signal, which has been produced during the longer exposure time, to the second image signal is increased. This results in an image demonstrating a high signal-to-noise ratio. When the luminance level is high, the ratio of the second image signal, which has been produced during the shorter exposure time, to the first image signal is increased. This results in a synthetic image that proves a wide dynamic range, depicts a smoothly varying brightness level, and exhibits a characteristic of being seen as almost natural. Moreover, the first and second image signals are produced to resemble those produced during mutually different exposure times by controlling an amount of light incident on an imaging device or by varying an amount of illumination light.

Imaging apparatus offering dynamic range that is expandable by weighting two image signals produced during different exposure times with two coefficients whose sum is 1 and adding them up

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&deg;)), 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.

In an endoscopic imagining system, a signal representing an object image produced by a scope and projected by a camera head is processed by a CCU and displayed as an endoscopic image on a TV monitor. The object image is stored as digital image data on a memory in the CCU, read as image data of a still image, and recorded on a PC card mounted in a PC card slot. The PC card slot is formed in the front panel or the like of the CCU. A lid member or the like functioning as an anti-liquid invasion member and shield can be located at an opening of the slot.

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.
