A light source device for an endoscope, characterized by having a light source for supplying illuminating light to an object, endoscope connection unit optically connected to an endoscope that has discrimination information for discriminating the kind of endoscope, discrimination unit for discriminating the endoscope based on the discrimination information of the endoscope connected to the endoscope connection unit, change unit for the changing illumination condition of the illuminating light, and control unit for controlling the change unit based on the result of discrimination by the discrimination unit.

Controlling light source with endoscope type

In an endoscope apparatus of the present invention, while observing a body cavity tissue under narrowband light via a second filter group of a rotating filter, a Gfilter section, Bfilter section, and shading filter section change illumination light to narrowband surface-sequential light of two bands of discrete spectral characteristics, and an image-capturing signal captured by a CCD via the B filter section constitutes a band image having superficial layer tissue information, and an image-capturing signal captured by a CCD via the G filter section constitutes a band image having intermediate layer tissue information. This produces tissue information of a desired depth in the vicinity of a superficial portion of a mucous membrane using an inexpensive and simple configuration.

Endoscope apparatus

A biological observation apparatus comprises a color image signal creating section that performs signal processing on either a first image pickup signal for which a subject to be examined illuminated by white illumination light is picked up by a color filter having a transmitting characteristic of a plurality of broadband wavelengths or a second image pickup signal for which a subject to be examined is picked up under illumination of frame sequential illumination lights which cover a visible range, and creates a color image signal. The biological observation apparatus comprises a spectral image signal creating section that creates a spectral image signal corresponding to a narrowband image signal through signal processing on a color image signal based on the first or second image pickup signal. The biological observation apparatus comprises one of a characteristic changing/setting section for a display color converting section that performs conversion of display colors when causing the spectral image signal to be displayed or the like, an interface section for performing an instruction operation for switching and/or confirming information including an image to be displayed, or the like.

Biological observation display apparatus for presenting color or spectral images

Tissue information of a desired deep portion of a biological tissue based on a spectral image obtained from signal processing is adjusted to image information in a color tone suitable for observation. Outputs of a matrix computing sectionare respectively connected to integrating sectionsto, and after integrating computation is performed for them, color conversion computation is performed for respective spectral image signals &#x3a3;Fto &#x3a3;Fin a color adjusting section, spectral color channel image signals Rch, Gch and Bch are created from the spectral image signals &#x3a3;Fto &#x3a3;F, and images of the spectral color channel images Rch, Gch and Bch are sent to a display monitorvia a switching section

Signal processing device for biological observation apparatus

An endoscopic system includes an endoscope having a delivery member available to supply a body cavity of a specimen and, in addition thereto, a gas supply apparatus from which predetermined gas is supplied to a body cavity via a delivery member. The endoscopic system further includes a determination unit that determines whether or not there is a status in which, the gas supply device needs to supply gas to the body cavity, and a control unit that selectively and automatically control a permit and stop for the gas supply to be implemented by the gas supply apparatus depending on a determined result of the determination unit, which are formed in a unitary structure with, for instance, the gas supply unit.

Endoscopic system equipped with gas supply apparatus

A medical image recording system easily obtains information of a device, etc. used at the time of an examination without conscious effort on operator's part, and records image information and the device information, which are obtained at the time of the examination, by making a 1-to-1 association between them. The system comprises at least an image information obtaining unit obtaining an observation image at the time of an examination for a medical treatment, a device information obtaining unit obtaining information of a device used at the time of the examination, and a recording unit recording information composing of the image information obtained by the image information obtaining unit and the device information obtained by the device information obtaining unit, as one associated information.

Medical image recording system

In a gas supply system, a selection unit is configured to send an instruction to select any one of first gas and second gas. In the gas supply system, a controller is operative to control at least one of a first gas supply unit for supplying the first gas and a second gas supply unit for supplying the second gas to selectively insufflate any one of the first gas and second gas into a body based on the instruction sent from the selection unit.
