Method and device for detecting obstruction in image sensor systems
First Claim
Patent Images
1. A method for the detection of an obstruction in an image sensor system, comprising:
- providing at least two image sensors, the at least two image sensors recording essentially the same scene; and
generating a signal indicating an obstruction of only one of the image sensors if images generated by the two image sensors deviate unacceptably from one another in at least one feature.

Abstract
A method and a device for the detection of obstruction in image sensor systems made up of at least two image sensors, which record essentially the same scene. If at least one image feature of the respective images differs unacceptably between the respective images, a signal is generated indicating the obstruction.

8. A method for the detection of an obstruction in an image sensor system, comprising:
-
providing at least two image sensors, the at least two image sensors recording essentially the same scene; and generating a signal indicating an obstruction of at least one of the image sensors if images generated by the image sensors deviate unacceptably from one another in at least one feature, wherein the feature is a histogram of gray-scale values of each of the images.

9. A device for the detection of an obstruction in an image sensor system having at least two image sensors which record essentially the same scene, the device comprising:
an evaluation unit for evaluating images generated by the image sensors and for generating a signal indicating an obstruction of only one of the image sensors if at least one feature deviates unacceptably in the images of the two image sensors. - View Dependent Claims (10)
