Abstract
The present disclosure provides computer-implemented methods, systems, and devices for estimation of a user's blue light exposure using the camera of a user computing device. A user computing device captures, using an ambient light sensor, information associated with a light environment of a user computing device. The user computing device determines a target exposure time. The user computing device captures, using a camera, image data by exposing a sensor of the camera to light for a time based on the target exposure time. The user computing device calculates white balance values for the captured image data using an automatic white balance algorithm. The user computing device discards the captured image data. The user computing device generates, based on the automatic white balance values, a blue light exposure value.
