Abstract

A spectrometry apparatus includes a wavelength variable interference filter emitting light of various predetermined wavelengths; a roll shutter imaging element having pixels accumulating electric charges when exposed to light, and forming one frame by photodetection for each pixel block including pixels with a predetermined time delay for each pixel block, in which the imaging element accumulates electric charges in a photodetection period, and outputs a detection signal in response to the accumulated electric charges in a non-photodetection period; and a spectroscopic controller controlling the wavelength change driving of the emitted light of the wavelength variable interference filter. For the one frame, the spectroscopic controller starts the wavelength change driving at an end timing of the photodetection period of a final pixel block for which the photodetection process is performed at the end.
