A capsule endoscope for endoscopic imaging is swallowable in a body, for image pickup of an object. In a capsule endoscopic system, a receiver receives image data in a form of a radio signal from the capsule endoscope, and for storing the image data. A computer as image processor produces an object image according to the image data from the receiver. A spectral image generator produces data of a spectral image having a wavelength band by arithmetic operation according to the image data. To this end, the spectral image generator arithmetically operates with a coefficient matrix to form the spectral image. Furthermore, capsule type information, assigned to the capsule endoscope discretely, is retrieved. The capsule type information is stored in a data storage medium, and read by the spectral image generator to determine the coefficient matrix.
