A measurement apparatus includes a light source, an interferometer, a light receiver, and a signal processor. The light source emits laser light to a scatterer in the atmosphere. The laser light has multiple oscillation frequencies separated from each other at equal frequency intervals. The interferometer produces interference in scattered light generated as a result of the laser light being scattered by the scatterer. The light receiver receives Mie scattered light included in the scattered light subjected to the interference produced by the interferometer and generates a signal. The signal processor detects the quantity of the Mie scattered light based on the signal. Each of the equal frequency intervals is smaller than the full width at half maximum of the peak of a frequency spectrum of Rayleigh scattered light. The Rayleigh scattered light is generated as a result of the laser light being scattered by molecules forming the atmosphere.

An image pickup device receives an incident light by way of the color filter that also transmits an infrared light component. For the purpose of correcting an infrared light component contained in an output signal, a control unit adds correcting infrared light components to image signals of multiple colors supplied from the image pickup device, respectively. To remove the infrared light components contained in the output signals, the correcting infrared light components are subtracted from the image signals of multiple colors supplied from the image pickup device. The control unit switches between an addition processing where an infrared light component is added and a subtraction processing where the infrared component is subtracted, according to a predetermined condition.
