The present invention relates to a physiological signals detection device. The physiological signals detection device has a light source connecting to a control unit, a light detector and a processing unit. The light detector has a pixel sensor array including multiple light sensors. The light source emits light through a lens to the human body to generate reflection. The light detector receives the reflection to generate a sensing signal. Since the light sensors respectively receives different reflections from different directions, the light sensors receiving reflections from the noise are easily selected and eliminated from calculating the physiology signal. Therefore, the calculated physiology signal is more accurate.本發明為一種生理訊號偵測裝置,係包含與控制單元連接的光源、光偵測單元及處理單元,光偵測單元具有感測器陣列,感測器陣列為多個光線感測元件所組成,光源發射光線,穿過透鏡後至人體部位產生反射光,再由光線感測元件接收反射光以產生感測訊號,由於各光線感測元件接收來自不同位置的反射光,故可加以區別哪些光線感測元件所接收到的反射光為雜訊,進而將雜訊排除於計算生理訊號之列,以提高所獲得之生理訊號的準確度。10‧‧‧第一光源11‧‧‧第二光源20‧‧‧光偵測單元21‧‧‧感測器陣列22‧‧‧可見光偵測單元23‧‧‧紅外光偵測單元24‧‧‧暗感測單元40‧‧‧處理單元41‧‧‧相關雙取樣電路42‧‧‧放大器43‧‧‧相加電路44‧‧‧類比數位轉換電路45‧‧‧暗電流補償電路46‧‧‧數位處理電路47‧‧‧串列介面50‧‧‧控制單元51‧‧‧時序控制器52‧‧‧紅外線發光二極體驅動器53‧‧‧電壓調節器54‧‧‧時脈產生器55‧‧‧控制暫存器56‧‧‧電源控制電路57‧‧‧中斷電路
