Abstract
Devices, methods, and systems for detecting false color in an image. An edge preserving filter is applied to an image sensor output to generate a first demosaiced image. A low pass filter is applied to the image sensor output to generate a second demosaiced image. A hue difference between the first demosaiced image and the second demosaiced image is calculated. A false color region is detected responsive to the hue difference exceeding a threshold hue difference.
