Violet narrowband light Vn and green narrowband light Gn produced by a light source device are supplied to a complementary color type endoscope, and simultaneously applied to an observation object. In a complementary color type imaging device, first mixed pixels and second mixed pixels, which sense both of the violet narrowband light Vn and the green narrowband light Gn, are read out. The light amount ratio Z of the violet narrowband light Vn to the green narrowband light Gn is set in such a range as to make the light amount of the violet narrowband light Vn larger than the light amount of the green narrowband light Gn, and make a signal value of the second mixed pixel higher than a signal value of the first mixed pixel.

A display device includes a main signal processing circuit to which color video data is input, and a plurality of sub-signal processing circuits to which video data for respective colors output by the main signal processing circuit are input. The main signal processing circuit generates information, which is used when each of the sub-signal processing circuits performs a predetermined process, based on information of a plurality of colors in the color video data input, and then outputs data representing the generated information to each of the sub-signal processing circuits together with the video data for the respective colors.

An image processing device includes a signal processing circuit, a chromatic aberration extraction circuit, and a diaphragm control circuit. The signal processing circuit generates image data by signal-processing output data generated by an image sensor in accordance with light passing through a diaphragm and a lens. The chromatic aberration extraction circuit extracts a chromatic aberration from the image data. The diaphragm control circuit changes an f-number of the diaphragm. The diaphragm control circuit sets the f-number of the diaphragm based on the chromatic aberration extracted by the chromatic aberration extraction circuit.
