Description

Translated fromJapanese

本発明は、複数種類の観察光で観察することを可能とする画像処理装置に関する。  The present invention relates to an image processing apparatus that enables observation with a plurality of types of observation light.

現在、体腔内にスコープを挿入することにより、食道、胃、小腸、大腸などの消化管や肺等の気管を観察し、必要に応じて処置具チャンネル内に挿通した処置具を用いて各種の治療処理のできる電子内視鏡が広く利用されている。
特に、光源装置から光学フィルタを通す等して赤、緑、青等の光を順次被写体に照射してモノクロの撮像素子で受光し、プロセッサ内で信号処理を行ってカラー画像として表示装置に出力する面順次式の内視鏡装置は国内で広く普及している。
At present, by inserting a scope into the body cavity, the gastrointestinal tract such as the esophagus, stomach, small intestine, and large intestine, and the trachea such as the lungs are observed. Electronic endoscopes that can be treated are widely used.
In particular, light such as red, green, and blue is radiated on the subject sequentially through an optical filter from the light source device and received by a monochrome image sensor, and signal processing is performed in the processor and output to a display device as a color image. The field sequential type endoscope apparatus is widely spread in Japan.

プロセッサ内の信号処理としては、病変の発見を容易にするために行われる色強調がある。色強調では、生体粘膜に含まれるヘモグロビンの量を基準にして色を強調する等して、正常粘膜と病変粘膜を色の差により明確に区別しやすくする。  Signal processing within the processor includes color enhancement that is performed to facilitate the detection of lesions. In color enhancement, the normal mucosa and the lesioned mucosa are clearly distinguished from each other by the color difference by emphasizing the color based on the amount of hemoglobin contained in the living mucosa.

また、内視鏡による診断では、肉眼で見えるのと同様のカラー画像をモニタに表示する通常観察の他に、生体組織の自家蛍光を利用した自家蛍光観察も行われ始めている。自家蛍光観察では、紫外〜青色の励起光を生体組織に当てた時に生体組織から出てくる自家蛍光のスペクトルが正常粘膜と腫瘍で異なることを利用して診断を行う。  In addition, in the diagnosis using an endoscope, in addition to normal observation in which a color image similar to that seen with the naked eye is displayed on a monitor, autofluorescence observation using autofluorescence of living tissue has begun to be performed. In autofluorescence observation, diagnosis is performed using the fact that the spectrum of autofluorescence emitted from a living tissue when ultraviolet to blue excitation light is applied to the living tissue differs between a normal mucosa and a tumor.

この自家蛍光の画像は、生体組織により反射されて戻ってくる反射光画像と共に、それぞれ異なる色を割り当ててモニタに表示されることにより、病変部を正常部との色の違いとして明確に認識できるようになる。蛍光は微弱なため、蛍光画像にはノイズが多く含まれ、蛍光観察用のプロセッサにはノイズ除去回路が搭載されることが多い。  This autofluorescence image is displayed on the monitor with a different color assigned to the reflected light image reflected back from the living tissue, so that the lesion can be clearly recognized as a color difference from the normal part. It becomes like this. Since the fluorescence is weak, the fluorescence image includes a lot of noise, and the processor for fluorescence observation is often equipped with a noise removal circuit.

また、例えば特開2002−95635号公報に開示されているように、通常の観察光よりも狭い帯域の光を照射して観察を行う、狭帯域光観察(NBI:NarrowBandImaging)というものも行われている。狭帯域光観察では、粘膜表層の血管をよりコントラスト良く観察することが可能になる。  In addition, as disclosed in, for example, Japanese Patent Application Laid-Open No. 2002-95635, narrow band light observation (NBI) is performed in which observation is performed by irradiating light in a narrower band than normal observation light. ing. In narrow-band light observation, blood vessels on the surface of the mucosa can be observed with higher contrast.

この狭帯域光観察は狭帯域の光で観察を行うため、通常の内視鏡画像とは異なった色調の画像が表示される。そこで、プロセッサ内に色変換回路を設けることにより色の調整を行い、より病変の判別に適した色調に変換してからモニタに出力して表示している。  Since this narrow-band light observation is performed with narrow-band light, an image having a color tone different from that of a normal endoscopic image is displayed. Therefore, color adjustment is performed by providing a color conversion circuit in the processor, and after conversion to a color tone more suitable for lesion determination, the color is output and displayed on a monitor.

これらの、通常観察、蛍光観察、狭帯域光観察は、照明光の切替が可能な照明装置を用いることにより、1つのシステムにまとめることが可能である。
特開2002−95635号公報
These normal observation, fluorescence observation, and narrow-band light observation can be combined into one system by using an illumination device capable of switching illumination light.
JP 2002-95635 A

本体、観察状態に応じて、通常観察、蛍光観察、狭帯域光観察等が適切に選択される必要がある。  Depending on the main body and observation state, normal observation, fluorescence observation, narrow-band light observation, etc. need to be appropriately selected.

蛍光観察は、主に病変部を発見するための観察法であるので、広い範囲を見渡すために遠景から観察することが有効である。逆に、狭帯域光観察は、細かい構造の観察が可能なので、見つかった病変をより詳しく観察するために用いられ、被写体に近づいて拡大して見たときに力を発揮する。  Since the fluorescence observation is an observation method mainly for finding a lesioned part, it is effective to observe from a distant view in order to look over a wide range. Conversely, narrowband light observation allows observation of fine structures, and is used to observe the found lesions in more detail, and exerts power when viewed close to the subject and magnified.

つまり、遠景からの観察には通常観察及び蛍光観察が適しているが、狭帯域光観察は不向きな観察である。逆に近接拡大観察時においては、通常観察及び狭帯域光観察が適しているが、蛍光観察は不向きな観察である。  That is, normal observation and fluorescence observation are suitable for observation from a distant view, but narrowband light observation is unsuitable for observation. Conversely, in close-up magnification observation, normal observation and narrow-band light observation are suitable, but fluorescence observation is unsuitable observation.

しかしながら、複数の観察を可能とした従来の電子内視鏡装置やプロセッサでは、観察状態に応じて通常観察、蛍光観察、狭帯域光観察を適切に切り替えることができないといった問題がある。  However, a conventional electronic endoscope apparatus or processor that enables a plurality of observations has a problem that normal observation, fluorescence observation, and narrowband light observation cannot be switched appropriately according to the observation state.

本発明は、上記事情に鑑みてなされたものであり、観察状態に応じて複数の観察モードを適切に切り替えることのできる画像処理装置を提供することを目的としている。  The present invention has been made in view of the above circumstances, and an object thereof is to provide an image processing apparatus capable of appropriately switching a plurality of observation modes according to an observation state.

このように構成された本実施例の作用について説明する。電子内視鏡3の挿入部20を体内に挿入し、光源装置3より複数の観察光(通常観察光、狭帯域光、励起光)を順次供給し、被検体に照射する。  The operation of this embodiment configured as described above will be described. Theinsertion part 20 of theelectronic endoscope 3 is inserted into the body, and a plurality of observation lights (normal observation light, narrow band light, excitation light) are sequentially supplied from thelight source device 3 and irradiated onto the subject.

電子内視鏡2では、通常観察光及び狭帯域光による被検体の光学像を通常観察光/狭帯域光用CCD24により撮像し、また、励起光による自家蛍光の被検体の光学像を蛍光用CCD26にて撮像する。  In theelectronic endoscope 2, an optical image of the subject with normal observation light and narrow band light is picked up by theCCD 24 for normal observation light / narrow band light, and an optical image of the autofluorescent subject with excitation light is used for fluorescence.

CPU58は、指示操作部59により制御状態が指示され、この指示に基づきフリーズメモリ部54、55、56及び画像合成回路57を制御する。  TheCPU 58 is instructed by theinstruction operation unit 59 and controls thefreeze memory units 54, 55, and 56 and theimage composition circuit 57 based on this instruction.

例えば指示操作部59により第1の制御状態にCPU58がある場合、ズームスイッチ27の調整状態がデフォルトの拡大率が小の状態の場合をCPU58が検出している際には、図4に示すように、フリーズメモリ部54、55、56を介した画像合成回路57によりモニタ4には、通常光画像及び蛍光画像が動画として表示される。そして、ズームスイッチ27が操作され、調整状態が所定の拡大率となり、CPU58がその状態(例えば拡大率:大)を検出すると、通常光画像及び狭帯域光画像が動画としてモニタ4に表示される。  For example, when theCPU 58 is in the first control state by theinstruction operation unit 59 and when theCPU 58 detects that the adjustment state of thezoom switch 27 is a state in which the default enlargement ratio is small, as shown in FIG. Furthermore, the normal light image and the fluorescence image are displayed as moving images on themonitor 4 by theimage composition circuit 57 via thefreeze memory units 54, 55 and 56. When thezoom switch 27 is operated and the adjustment state becomes a predetermined enlargement ratio, and theCPU 58 detects the state (for example, enlargement ratio: large), the normal light image and the narrowband light image are displayed on themonitor 4 as moving images. .

また、例えば指示操作部59により第2の制御状態にCPU58がある場合、ズームスイッチ27の調整状態がデフォルトの拡大率が小の状態の場合をCPU58が検出している際には、図5に示すように、フリーズメモリ部54、55、56を介した画像合成回路57によりモニタ4には、蛍光画像及び狭帯域光画像が動画として表示される。そして、ズームスイッチ27が操作され、調整状態が所定の拡大率となり、CPU58がその状態(例えば拡大率:大)を検出すると、フリーズメモリ部56に格納されている蛍光画像が静止画として、また狭帯域光画像が動画としてモニタ4に表示される。  Further, for example, when theCPU 58 is in the second control state by theinstruction operation unit 59, and when theCPU 58 detects that the adjustment state of thezoom switch 27 is a state where the default enlargement ratio is small, FIG. As shown, the fluorescence image and the narrowband light image are displayed as a moving image on themonitor 4 by theimage composition circuit 57 via thefreeze memory units 54, 55 and 56. Then, when thezoom switch 27 is operated, the adjustment state becomes a predetermined enlargement ratio, and theCPU 58 detects the state (for example, enlargement ratio: large), the fluorescent image stored in thefreeze memory unit 56 becomes a still image or A narrow band light image is displayed on themonitor 4 as a moving image.

また、例えば指示操作部59により第3の制御状態にCPU58がある場合、ズームスイッチ27の調整状態がデフォルトの拡大率が小の状態の場合をCPU58が検出している際には、図6に示すように、フリーズメモリ部54、55、56を介した画像合成回路57によりモニタ4には、蛍光画像及び狭帯域光画像が動画として表示される。そして、ズームスイッチ27が操作され、調整状態が所定の拡大率となり、CPU58がその状態(例えば拡大率:大)を検出すると、狭帯域光画像のみが動画としてモニタ4に表示される。  In addition, for example, when theCPU 58 is in the third control state by theinstruction operation unit 59, and when theCPU 58 detects that the adjustment state of thezoom switch 27 is a state where the default enlargement ratio is small, FIG. As shown, the fluorescence image and the narrowband light image are displayed as a moving image on themonitor 4 by theimage composition circuit 57 via thefreeze memory units 54, 55 and 56. When thezoom switch 27 is operated, the adjustment state becomes a predetermined enlargement ratio, and theCPU 58 detects the state (for example, enlargement ratio: large), only the narrow-band light image is displayed on themonitor 4 as a moving image.

さらに、例えば指示操作部59により第4の制御状態にCPU58がある場合、ズームスイッチ27の調整状態がデフォルトの拡大率が小の状態の場合をCPU58が検出している際には、図7に示すように、フリーズメモリ部54、55、56を介した画像合成回路57によりモニタ4には、通常光画像が動画として表示される。そして、ズームスイッチ27が操作され、調整状態が所定の拡大率となり、CPU58がその状態(例えば拡大率:大)を検出すると、狭帯域光画像が動画としてモニタ4に表示される。  Further, for example, when theCPU 58 is in the fourth control state by theinstruction operation unit 59, and when theCPU 58 detects that the adjustment state of thezoom switch 27 is a state where the default enlargement ratio is small, FIG. As shown, the normal light image is displayed as a moving image on themonitor 4 by theimage composition circuit 57 via thefreeze memory units 54, 55, and 56. Then, when thezoom switch 27 is operated, the adjustment state becomes a predetermined enlargement ratio, and theCPU 58 detects the state (for example, enlargement ratio: large), a narrow band light image is displayed on themonitor 4 as a moving image.

このように本実施例では、ズームスイッチ27による観察状態に応じて、CPU58の制御により複数の観察モードを適切に切り替えることができる。  As described above, in this embodiment, the plurality of observation modes can be appropriately switched by the control of theCPU 58 in accordance with the observation state by thezoom switch 27.

なお、指示操作部59による制御状態によりCPU58がフリーズメモリ部54、55、56及び画像合成回路57を制御し、モニタに表示する表示形態は上記形態(図4、図5、図6及び図7)に限らないことはいうまでもない。  Note that theCPU 58 controls thefreeze memory units 54, 55, and 56 and theimage composition circuit 57 according to the control state of theinstruction operation unit 59, and the display form displayed on the monitor is the above form (FIGS. 4, 5, 6, and 7). Needless to say, it is not limited to.

また、本実施例では、ビームスプリッタ23により光路を分離し、通常観察光/狭帯域光用CCD24及び蛍光用CCD26により撮像するとしたが、これに限らず、図8に示すように、通常観察光/狭帯域光用CCD24及び蛍光用CCD26の対物光学系を2系統設けるようにしてもよい。  In this embodiment, the optical path is separated by thebeam splitter 23 and the normal observation light / narrowbandlight CCD 24 and thefluorescence CCD 26 are used for imaging. However, the present invention is not limited to this, and as shown in FIG. / It is also possible to provide two objective optical systems for the narrowband light CCD 24 and thefluorescence CCD 26.
