PROBLEM TO BE SOLVED To detect noise to be removed from a measurement signal related to an object.SOLUTION: The measuring apparatus 1 comprises a light emitting part 11 for irradiating light to a living body, a first light receiving part and a second light receiving part 12 for receiving the return light from the living body of the irradiated light respectively , 13), information on the noise of at least one of the output signal of the first light receiving section and the output signal of the second light receiving section, based on the output signal of the first light receiving section and the output signal of the second light receiving section And an output unit (100) for outputting the image. According to the measurement device, it is possible to easily detect whether or not noise to be removed is included in the measurement signal concerning the living organism.(FIG.【課題】対象物に係る計測信号から除去すべきノイズを検出する。【解決手段】計測装置(1)は、生体に対し光を照射する発光部(11)と、照射された光の生体からの戻り光を夫々受光する第1受光部及び第2受光部(12、13)と、第1受光部の出力信号と第2受光部の出力信号とに基づいて、第1受光部の出力信号及び第2受光部の出力信号の少なくとも一方の出力信号の雑音に関する情報を出力する出力手段(100)と、を備える。当該計測装置によれば、生体に係る計測信号に、除去すべきノイズが含まれているか否かを容易に検出することができる。【選択図】図6
