Problems solved by technology

However, this first conventional example neither suggests nor discloses light quantity control etc. corresponding to the function of the photosensitive substance based on methylene blue.
[0010] That is, the function of the staining agent based on methylene blue can be used to easily recognize the unevenness of the observation target site, but in this first conventional example, the amount of light in the red wavelength region is increased without considering the effect of the photosensitive material. Function, so active oxygen species also increase
[0011] Also, in the third conventional example, the case where signal processing is performed is not disclosed
[0012] Therefore, in the conventional example, there is no disclosure of an endoscope device that takes into account the characteristics of the photosensitive substance, and it does not disclose that signal processing corresponding to light quantity control taking into account the characteristics of the photosensitive substance is performed.

Embodiment 1

[0033] Refer to Figure 1 to Figure 4B Example 1 of the present invention will be described.

[0034] As shown in Figure 1, the endoscope device 1 of Embodiment 1 of the present invention comprises: electronic endoscope (hereinafter abbreviated as endoscope) 3, and it can be inserted in the body cavity, to the observation object such as the affected part in the body cavity The part 2 is photographed for endoscopic observation, etc.; the light source device 4 is detachably connected to the endoscope 3 to generate illumination light for observation; the processor 5 is detachably connected to the endoscope 3 The scope 3 is connected, and performs signal processing and the like for the captured image signal; and the monitor 6, which is connected to the processor 5, is input with the image signal output from the processor 5, and displays the image corresponding to the image signal. image.

[0035] The endoscope 3 has an elongated insertion portion 8 inserted into a body cavity, a...

Embodiment 2

[0095] Next, Embodiment 2 of the present invention will be described with reference to FIGS. 5 and 6 . FIG. 5 shows the configuration of a simultaneous endoscope device 1B according to the second embodiment.

[0096] This endoscope device 1B is composed of an endoscope 3B, a light source device 4B, a processor 5B, and a monitor 6 .

[0097] The endoscope 3B is a simultaneous type endoscope having a color imaging CCD provided with a color separation filter 51 on the imaging surface of the CCD 15 in addition to the endoscope 3 of FIG. 1 . And, in the operation part 9 of this endoscope 3B, similar to the case of the first embodiment, there are provided: a mode switching switch SW1, which is used to switch to the first observation mode corresponding to normal observation; a light amount increase switch SWu, It performs an instruction operation to increase the light quantity of the red illumination light in the second observation mode, and a light quantity reduction switch SWd for...

Embodiment 3

[0122]Embodiment 3 of the present invention will be described below with reference to FIG. 7 . Example 3 has a structure in which, for example, a part of Example 2 is changed. FIG. 7 shows the structure of a light source device 4C in Embodiment 3. As shown in FIG. This light source device 4C has a structure in which, for example, in the light source device 4B in FIG. Optionally configured in the illumination light path.

[0123] The operation of the filter insertion and removal device 61 is controlled by the light source control circuit 29 . In this embodiment, the state in which no filter is disposed in the illumination optical path corresponds to the state in which the transparent portion 53T is disposed in the illumination optical path in Embodiment 2, that is, normal observation.

[0124] Then, when the first filter 62a or the second filter 62b is disposed in the illumination optical path by the filter insertion and removal device 61, the first bandpass filter 53A or th...

Abstract

An endoscopic device comprises an endoscope having an insertion part insertable into an organism, an illumination part for emitting illumination light to the side of a portion to be observed in the organism, a light quantity control part for controlling the light quantity so that the light quantity of the red wavelength range exciting a light sensitizer given to the portion to be observed and illuminated with the illumination light is at least reduced, and a signal processing part for performing a signal processing to increase the luminance level of a red color signal corresponding to the red wavelength range in taking an image under the illumination light in response to the light quantity control.

Description

technical field [0001] The present invention relates to endoscopic devices suitable for observing living organisms dispersed with photosensitive substances. Background technique [0002] In the medical field, a living body is sometimes dyed (colored) so that unevenness and the like can be more easily recognized for endoscopic observation. Methylene blue (methylene blue) is widely used as a coloring agent (coloring agent) for dyeing in this way. [0003] For example, Japanese Patent Application Laid-Open No. 5-84218, which is a first conventional example, discloses an endoscope apparatus for endoscopic observation by staining with methylene blue. [0004] Furthermore, Japanese Patent Application Laid-Open No. 6-339459, which is a second conventional example, discloses an endoscope apparatus capable of performing chromoendoscopy using a dye. In addition, this publication also discloses a function of changing the light quantity of illumination light. [0005] Figure 11 It s...
