US 2022/0398779 A1 · Compensating for Optical Change in Image Capture Device Components Over Time

Abstract

Devices, methods, and non-transitory program storage devices (NPSDs) are disclosed to compensate for the predicted color changes experienced by camera modules after certain amounts of time of real world use. Such color changes may be caused by prolonged exposure of optical components of the camera module to one or more of: solar radiation, high temperature conditions, or high humidity conditions, each of which may, over time, induce deviation in the color response of optical components of the camera module. The techniques disclosed herein may first characterize such predicted optical change to components over time based on particular environmental conditions, and then implement one or more time-varying color models to compensate for predicted changes to the camera module's color calibration values due to the characterized optical change. In some embodiments, optical changes in other types of components, e.g., display devices, caused by prolonged environmental stresses may also be modeled and compensated.
