Abstract

See full text

An imaging system including an image sensor coupled to a controller to image an external scene is described. The controller includes logic storing instructions that when executed causes the imaging system to perform operations including capturing images, including a first image and a second image, of an external scene, and generating reduced representations of the images including a first reduced representation associated with the first image and a second reduced representation associated with the second image. The operations further include comparing the first reduced representation with the second reduced representation to determine a difference between the first image and the second image and identifying an occurrence of an occlusion affecting the image sensor imaging the external scene when the difference is greater than a threshold value.
