1. A device, comprising:
a memory;
one or more image capture devices; and
one or more processors operatively coupled to the memory, wherein the one or more processors are configured to execute instructions causing the one or more processors to:
obtain a time-varying color model for a first component of a first image capture device of the one or more image capture devices, wherein the time-varying color model is configured to model an amount of color calibration to apply to the first image capture device over time to compensate for optical change in the first component, and wherein the time-varying color model is refined by input data from one or more applications executing on the device;
obtain a first image captured by the first image capture device at a first time; and
color correct the first image according to the time-varying color model and the first time.
