Abstract
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 of image sensor pixels. The array of image sensor pixels may include a corresponding array of color filter elements. The system may include circuitry configured to detect and mitigate flare artifacts in image data captured using the image sensor. Detecting the flare artifacts may include detecting color mismatches in the captured image data and performing edge-detection operations to determine whether the color mismatches are in an edge region of the image data. If the color mismatches are detected in an edge region, no flare-mitigation operations may be performed. If the color mismatches are in a flat region of the captured image, flare-mitigation operations may be performed.
