Claim Text:
1. An endoscope system comprising: a light source that can emit first narrow band light and second narrow band light different from the first narrow band light sequentially; a color filter that is formed by disposing at least a first filter and a second filter, the first filter having a spectral characteristic that makes a transmittance in a band of a first color component including a band of the first narrow band light relatively higher than a transmittance in other bands, and the second filter having a spectral characteristic that makes a transmittance in a band of a second color component including a band of the second narrow band light relatively higher than a transmittance in other bands; an image pickup sensor that is configured to receive light passing through the first filter in a first pixel and receive light passing through the second filter in a second pixel different from the first pixel, and can set an exposing period and a reading period of an electric signal for each pixel; and a controller that performs control for causing the first narrow band light to be emitted, causing the first pixel to be exposed, and reading an electric signal from the second pixel in a first period, and causing the second narrow band light to be emitted, causing the second pixel to be exposed, and reading an electric signal from the first pixel in a second period different from the first period.
