To provide a technology to suppress an influence of another biological information which is different from biological information to be measured in measuring biological information.SOLUTION: A measuring apparatus includes: means for irradiating a light toward a measurement position; spectral means for spectrally diffusing reflection light from a living body at a measurement position according to a wavelength; light receiving means including a plurality of pixels for receiving light including a predetermined wavelength spectrally diffused by the spectral means; detection means for detecting a sampling value indicating light receiving results of the plurality of pixels at sampling timing; means for generating a biological signal related to first biological information from the sampling value at each sampling timing of a first pixel of the light receiving means; and means for determining a cycle of the biological signal. The detection means selects sampling timing on the basis of the cycle of the biological signal, and detects second biological information on the basis of the sampling value at the selected sampling timing of one or more second pixels of the light receiving means.SELECTED DRAWING: Figure 1 【課題】生体情報の測定において、当該生体情報とは異なる他の生体情報の影響を抑える技術を提供する。【解決手段】測定装置は、測定位置に向けて光を照射する手段と、測定位置にある生体からの反射光を波長に応じて分光する分光手段と、複数の画素を有し、分光手段が分光した所定の波長を含む光を受光する受光手段と、サンプリングタイミングにおいて複数の画素の受光結果を示すサンプリング値を検出する検出手段と、受光手段の第１画素の各サンプリングタイミングにおけるサンプリング値から第１生体情報に関連する生体信号を生成する手段と、生体信号の周期を判定する手段と、を備え、検出手段は、生体信号の周期に基づきサンプリングタイミングを選択し、受光手段の１つ以上の第２画素の選択したサンプリングタイミングにおけるサンプリング値に基づき第２生体情報を検出する。【選択図】図１
