Provided is an information processing apparatus (100) including: an image acquiring unit (112) that acquires captured image information of a sample (20) dyed with a fluorescent dye reagent (10), an information acquiring unit (111) that acquires information related to the fluorescent dye reagent (10), a correcting unit (131) that corrects the luminance of the captured image information using a fluorescence fading coefficient that represents the rapidness at which the fluorescence intensity of the fluorescent dye reagent (10) drops, the fluorescence fading coefficient being included in the fluorescent dye reagent (10), and a calculating unit (132) that calculates information corresponding to fluorescent molecules in the captured image information, using the corrected luminance.

A gas sensor for measuring concentration of a predetermined gas includes a light source (2) arranged to emit pulses of light, a measurement volume (10), a detector (4) arranged to receive light that has passed through the measurement volume (10), and an adaptable filter (6) disposed between the light source (2) and the detector (4). The gas sensor has a measurement state in which it passes at least one wavelength band which is absorbed by the gas and a reference state in which said wavelength band is attenuated relative to the measurement state. A controller is connected to each of the light source, the detector and the adaptable filter to change the adaptable filter between one of said measurement state and said reference state to the other at least once during a gas sensor operation period.
