PHYSIOLOGICAL SIGNALS DETECTION DEVICE
First Claim
1. A physiological signals detection device comprising:
- a first light source providing a first light beam;
a light detector havinga pixel sensor array having multiple first light sensing elements and detecting a reflected light resulted from the first light beam emitted from the first light source to a user'"'"'s body to generate a first sensing signal;
a lens covering on the light detector, and the pixel sensor array receiving the reflected light of the first light beam through the lens;
a processing unit connecting to the light detector and calculating the user'"'"'s heartbeat value based on the first sensing signal; and
a control unit connecting to the first light source, the light detector and the processing unit, switching the first light source on and off, controlling the light detector to sense and controlling the processing unit to process signals.

Abstract
A 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 sensing elements. The light source emits light through a lens to the human body to generate reflected light. The light detector receives the reflected light to generate a sensing signal. Since the light sensing elements respectively receive different reflected light from different directions, the light sensing elements receiving reflected light from the noise are easily selected and eliminated from calculating the physiology value. Therefore, the calculated physiology value is more accurate.
