METHOD AND APPARATUS FOR DETERMINING BLOOD OXYGENATION USING A MOBILE COMMUNICATION DEVICE
First Claim
1. A method comprising:
- capturing a plurality of images of skin using an array of pixels in a camera on a portable electronic device;
comparing image characteristics corresponding to the plurality of captured images at a first wavelength with image characteristics corresponding to the plurality of captured images at a second wavelength, the second wavelength being substantially distinct from the first wavelength; and
determining blood oxygen level based on comparing the image characteristics.

Abstract
A method (300) and apparatus (110) that determines blood oxygenation using a mobile communication device is disclosed. The method can include capturing (320) a plurality of images of skin using an array of pixels in a camera on a portable electronic device. The method can include comparing (330) image characteristics corresponding to the plurality of captured images at a first wavelength with image characteristics corresponding to the plurality of captured images at a second wavelength, the second wavelength being substantially distinct from the first wavelength. The method can include determining (340) blood oxygen level based on comparing the image characteristics.
