Summary:PROBLEM TO BE SOLVED: To provide a bio-information expectation device capable of expecting user's pulse number at high-accuracy without contact by image processing of user's skin color region included in obtained image data even in a case where image data photographed by the user has drop of frame.SOLUTION: A bio-information expectation device 10 comprises: an image input part 1 inputting image data of photographed human; an extracting part extracting signals within a predetermined range of the input image data by the image input part, a plurality of filter parts outputting, with different coefficients, each of signals corresponding to different coefficients in signals within the predetermined range extracted by the extracting part; a plurality of expectation parts which are arranged correspondingly to the filter parts respectively and which expects human pulse value based on output of corresponding filter part and input interval of frames of the image data input by the image input part; an output part selecting and outputting any of a plurality of pulse values expected by the plurality of expectation parts according to output of the plurality of filter parts.SELECTED DRAWING: Figure 3 【課題】ユーザが撮像された画像データのフレームのコマ落ちが発生した場合でも、取得した画像データに含まれるユーザの肌色領域の画像処理により、ユーザの脈拍数を非接触で高精度に推定することができる生体情報推定装置を提供する。【解決手段】生体情報推定装置10は、人が撮像された画像データを入力する画像入力部1と、画像入力部により入力された画像データの所定範囲の信号を抽出する抽出部と、異なる係数を用いて、抽出部により抽出された所定範囲の信号のうち異なる係数に対応する各信号を出力する複数のフィルタ部と、各々のフィルタ部に対応して設けられ、対応するフィルタ部の出力と画像入力部により入力された画像データのフレームの入力間隔とを基に、人の脈拍値を推定する複数の推定部と、複数のフィルタ部の出力に応じて、複数の推定部により推定された複数の脈拍値からいずれかを選択して出力する出力部と、を備える。【選択図】図3
