Abstract: An imaging device including a condenser lens and an image sensor is provided. The image sensor is configured to sense light penetrating the condenser lens and includes a pixel matrix, an opaque layer, a plurality of microlenses and an infrared filter layer. The pixel matrix includes a plurality of infrared pixels, a plurality of first pixels and a plurality of second pixels. The opaque layer covers upon a first region of the first pixels and a second region of the second pixels, wherein the first region and the second region are mirror- symmetrically arranged in a first direction. The plurality of microlenses is arranged upon the pixel matrix. The infrared filter layer covers upon the infrared pixels.

Abstract: A physiological detection device including a light source, an image sensor and a processor is provided. The light source illuminates a skin surface using a burst mode. The image sensor receives ejected light from skin tissues under the skin surface at a sampling frequency to successively generate image frames. The processor controls the light source and the image sensor, and calculates a physiological characteristic according to the image frames captured when the light source is illuminating light. The physiological detection device reduces the total power consumption by adopting the burst mode.
