  • Patent number: 6636254
    Abstract: 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.

  • Publication number: 20030122927
    Abstract: 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.

  • Publication number: 20030025789
    Abstract: One expansion substrate or a plurality of expansion substrates that realize different facilities can be connected to a main substrate that realizes basic processing to be performed by a CCU. Based on an ID number produced by an ID generation unit mounted on a connected expansion substrate, a CPU incorporated in the CCU identifies the facility realized with the expansion substrate. A menu screen image presents item BOD Control under which the facilities are presented. When item BOD Control is designated, a BOD Control screen image that lists control items indicating the facilities realized with all the expansion substrates that are connected to the main substrate is displayed. When a concrete facility such as a P-in-P facility realized with an expansion substrate is selected or designated in the BOD Control screen image, a screen image concerning the designated P-in-P facility is displayed. Thus, the details of a facility that is realized with a connected expansion substrate can be set easily.

  • Patent number: 6480762
    Abstract: A plurality of pieces of medical equipment each of which includes a microcomputer and has a program used to control the microcomputer stored in a reproqrammable storage device such as an EEPROM is linked to a remote computer over a communication line. Using a rewriting/updating program sent from the computer, each piece of medical equipment rewrites or updates the program stored in the storage device. When a plurality of programs is stored, if one of the programs is rewritten or updated abnormally, the other program is used to activate medical equipment.

  • Patent number: 6456317
    Abstract: 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.

  • Patent number: 6184922
    Abstract: 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.
