Imaging systems and methods for location-specific image flare mitigation

摘要

An imaging system may include a camera module with an image sensor having an array of image sensor pixels and one or more lenses that focus light onto the array. The system may include processing circuitry configured to mitigate flare artifacts in image data captured using the array based on at least one image flare map. The image flare map may identify a portion of the captured image data on which to perform image flare mitigation operations. The processing circuitry may perform image flare mitigation operations such as pixel value desaturation on the identified portion of the captured image data without desaturating portions of the image data that do not include flare artifacts. The flare map may be generated using a calibration system that characterizes the location, intensity, and color of all possible image flare artifacts that may be generated by the imaging system during normal imaging operations.

1. A method for operating an imaging system having a plurality of image sensor pixels and processing circuitry, the method comprising:
with the plurality of image sensor pixels, capturing image data, wherein the imaging system uses adjustable image capture settings when capturing the image data; with the processing circuitry, identifying an image flare map to be used based on the adjustable image capture settings used when capturing the image data; and with the processing circuitry, performing image flare mitigation operations on the captured image data based on the identified image flare map.
