As for endoscope device 1, in the light equipment reflected light of the illumination light which was irradiated 4 which illuminates illumination light vis-a-vis the suffering inspection body and the suffering inspection body absorbing light, as it generates the 1st picture signal at least to suppress the high frequency component from the even image of the image pickup signal of the narrow band wavelength of two or more on the basis of the image pickup signal which is obtained by CCD2 and CCD2 which image pickup it does the suffering inspection body, the image processing section 101 which generates the 2nd picture signal to suppress the high frequency component from the difference image of the image pickup signal of specified two narrow band wavelengths and, the 1st picture signal and the 2nd picture signalAllocating to the specified color channel of 1, or more it has the observation monitor 5 which displays.内視鏡装置1は、被検体に対して照明光を照明する光源装置4と、被検体に照射された照明光の反射光を受光して被検体を撮像するCCD2と、CCD2により得られた撮像信号に基づいて、少なくとも2つ以上の狭帯域波長の撮像信号の平均画像から高周波成分を抑制した第1画像信号を生成すると共に、所定の2つの狭帯域波長の撮像信号の差分画像から高周波成分を抑制した第2画像信号を生成する画像処理部101と、第1画像信号及び第2画像信号を1以上の所定の色チャンネルに割り当てて表示を行う観察モニタ5を備える。
