Abstract
The present invention is an image based oxygen saturation measuring device and method thereof. The method comprises steps of providing a plurality of red lights and a plurality of infrared lights arranged uniformly in an interlocked fashion and turned on alternatively; controlling the plurality of red lights and infrared lights to irradiate onto a selected skin area of a testee to have a red light turn-on period and an infrared light turn-on period; receiving a reflected version of the plurality of red lights and infrared lights from the selected skin area, respectively; and analyzing one reflected red light and one infrared light to acquire an oxygen saturation index for each of the coordination points. By means of the present invention, the measurement of oxygen saturation may be much exempted from effects brought from exterior interference and poor blood circulation, and may achieve a large measurement area in a single time.
