Abstract:
1. An optical module comprising: a spectroscopic element that selects light of a predetermined wavelength from incident light, and emits the selected light as emitted light, the spectroscopic element being operable to emit light having one of a plurality of wavelengths; a global shutter imaging element that accumulates electric charges while being exposed to the emitted light, and outputs a detection signal in response to the accumulated electric charges; an imaging element controller that sets: a spectroscopic controller that controls the wavelength change driving of the emitted light in the spectroscopic element, wherein the imaging element controller sets a duration of the standby period equal to or greater than a minimum drive time for changing the wavelength of the emitted light, and wherein the spectroscopic controller starts the wavelength change driving of the spectroscopic element at a start of the standby period.
