An infrared fluorescent image can be obtained by infrared light without degrading the resolution of the normal image by white light and the sensitivity of each color, particularly G (green), and without degrading the image quality. Provided is an endoscope system that is simple in configuration, low in changes and modifications, and low in cost. A light source device that emits white light and infrared light by switching them in time series, and imaging for acquiring a color image and an infrared image of an observation site illuminated by white light and infrared light, respectively. The image pickup device includes a plurality of image pickup elements that form pixels corresponding to each pixel of a color image, and a color filter disposed in front of the plurality of image pickup elements, and each of the color filters includes a plurality of image pickup elements. And having a plurality of types of specific wavelength transmission filters that transmit different electromagnetic waves, and one or more types of specific wavelength transmission filters are also transmitted in a specific wavelength region of the infrared wavelength region, and are the same The above problem is solved by acquiring an image signal corresponding to switching between white light and infrared light from the image sensor of the pixel.
