PROBLEM TO BE SOLVED: To provide a medical apparatus capable of generating an observation image synthesized to have brightness and resolution suitable for fluorescence observation.SOLUTION: A medical apparatus includes a light source section, an image pickup section that picks up respective images of fluorescent and reflected light, a pixel addition processing section that performs pixel addition processing of making a plurality of pixels in a fluorescent image obtained by picking up an image of fluorescent light as one pixel, an adjusting section that makes adjustment of brightness so that the brightness ratio of the fluorescent image to which pixel addition processing is performed and a reference light image obtained by picking up the image of the reflected light is a constant value, an interpolation processing section that applies interpolation processing to the fluorescent image having brightness adjusted, and an image processing section that synthesizes the fluorescent image to which pixel interpolation processing is performed and the reference light image. In this case, the adjusting section includes an amplification section for amplifying brightness of the fluorescent image to which pixel addition processing is performed and by varying the combination of the addition pixel number of the pixel addition processing and the amplification ratio of the amplification section, the brightness is adjusted so that the brightness ratio of the fluorescent image and the reference light image is a constant value.COPYRIGHT: (C)2013,JPO&INPIT【課題】蛍光観察に適した明るさ及び解像度を具備するように画像合成された観察画像を生成可能な医療装置を提供する。【解決手段】医療装置は、光源部と、蛍光と反射光とをそれぞれ撮像する撮像部と、蛍光を撮像して得られた蛍光画像における複数画素を1画素とする画素加算処理を行う画素加算処理部と、画素加算処理が施された蛍光画像と反射光を撮像して得られた参照光像との明るさ比が一定値になるように明るさを調整する調整部と、明るさが調整された蛍光画像に対して画素補間処理を施す補間処理部と、画素補間処理が施された蛍光画像と参照光画像とを合成する画像処理部と、を有し、調整部は、画素加算処理が施された蛍光画像の明るさを増幅する増幅部を有し、画素加算処理の加算画素数及び増幅部の増幅率の組み合わせを変更することにより、蛍光画像と参照光像との明るさ比が一定値になるように明るさを調整する。【選択図】図1
