摘要： Lightness and/or imaging magnification during imaging of an endoscopic image is detected. Further, a wavelength set for a spectral estimation image and matrix parameter are automatically selected based on the lightness and/or the imaging magnification. Further, the spectral estimation image is generated by performing matrix operation on the endoscopic image by using the matrix parameter.

摘要： An input of one of a plurality of combinations of wavelength components that have been set in advance is received. Further, a spectral estimation image signal obtainment mode and a narrow-band image signal obtainment mode are switched therebetween based on the combination of wavelength components that has been received to obtain a spectral estimation image signal or a narrow-band image signal.

摘要： An endoscope image is obtained by imaging a subject with a scope. Then, an edge portion of the endoscope image is extracted and a complexity degree of the edge portion is detected. Thereafter, a determination is made as to whether the endoscope image is an image obtained through near view imaging or distant view imaging according to the complexity degree and an imaging condition is changed according to the determined near view imaging or distant view imaging.

摘要： An imaging mode is automatically switched based on the kind of a subject. The spatial frequency of an endoscopic image obtained by imaging the subject is detected. Further, judgment is made, based on the distribution of the spatial frequency, as to whether the endoscopic image was obtained by performing close-up imaging on the subject. The condition of imaging is switched based on the result of judgment as to whether the image was obtained by close-up imaging or distant-view imaging.

摘要： A narrow-band observation image and a spectral estimation image are automatically switched based on the type of a subject. In an endoscopic image obtained by a scope, judgment is made as to whether the endoscopic image was obtained by close-up imaging or by distant-view imaging. When it is judged that the endoscopic image was obtained by distant-view imaging, white light is output from a light source unit and a spectral estimation image is output. When it is judged that the endoscopic image was obtained by close-up imaging, narrow-band light is output from the light source unit and a narrow-band observation image that has been obtained when the narrow-band light was output is output.
