Abstract
An optical module includes a wavelength variable interference filter that selects light of a predetermined wavelength from incident light, and can change the wavelength of emitted light; 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 for setting a photodetection period during which the electric charges are accumulated in the imaging element, and a standby period during which the electric charges accumulated in the imaging elements are reset; and a spectroscopic controller for controlling the wavelength change driving of the emitted light. The imaging element controller sets the duration of the standby period to a minimum drive time for changing the wavelength or greater. The spectroscopic controller starts the wavelength change driving at the start of the standby period.
