FIG3 is a schematic diagram illustrating the configuration of the imaging unit 92. The imaging unit 92 has, as illustrated in FIG3, a first imaging element 921, a second imaging element 922, and a prism 923. In the imaging unit 92, observation light from the outside enters the prism 923 via the lens unit 91, and light spectrally separated by the prism 923 enters the first imaging element 921 and second imaging element 922.  Illumination timings of the illumination light emitted by the light source device 6 will be described next by reference to FIG4. FIG4 is a diagram illustrating illumination timings in the endoscope apparatus according to the first embodiment of the present invention. According to the description hereinafter, under control by the control unit 55, the light source control unit 63 controls each unit and causes the illumination light to be emitted. Under control by the control unit 55, the imaging unit 92 and the light source device 6 operate in synchronization with each other. Because the first imaging element 921 and the second imaging element 922 are CMOSs, the electric charge is sequentially read per line.

['1. An endoscope apparatus, comprising: a light source device configured to continuously emit first light of a first wavelength band, and sequentially emit second light of plural second wavelength bands different from the first wavelength band and different from each other; and an imaging device including: a spectroscopic unit configured to spectrally separate light from a subject, the light arising from illumination light emitted by the light source device, into light of the first wavelength band and light of the second wavelength bands; a first imaging element configured to generate a first image signal by receiving and photoelectrically converting the light of the first wavelength band spectrally separated by the spectroscopic unit; and a second imaging element configured to generate a second image signal by respectively receiving and photoelectrically converting the light of the second wavelength bands spectrally separated by the spectroscopic unit.']
