Method for operating a camera assembly, camera assembly and driver assistance system
First Claim
1. A method for operating a camera assembly for a vehicle, in which a first camera and a second camera capture images, wherein respective fields of view of the two cameras overlap at least in a partial region, and in which at least in an image captured by the first camera at least one contamination region including a plurality of pixels is detected within the partial region, the method comprising:
- altering data values specifying the respective transparency of the pixels in the at least one contamination region with respect to respective reference values of the transparency, which increase in the partial region towards an edge of the respective image upon superimposition of the images,wherein in the image captured by the second camera, the data values specifying the respective transparency of pixels in an image region superimposed with the at least one contamination region are decreased with respect to the respective reference values, andwherein that the data value of a pixel specifying the transparency in the image captured by the first camera is increased by an amount, by which the data value of a pixel superimposed with this pixel in the image captured by the second camera is decreased.

Abstract
The invention relates to a method for operating a camera assembly, in which a first camera and a second camera capture images (36, 42). Respective fields of view of the two cameras overlap at least in a partial region (24). At least in an image (36) captured by the first camera, at least one contamination region (38) including a plurality of pixels is detected within the partial region (24). Thereupon, data values specifying the respective transparency of the pixels in the at least one contamination region (38) are varied with respect to respective reference values of the transparency, wherein these reference values increase in the partial region (24) towards an edge (28) of the respective image upon superimposition of the images. Furthermore, the invention relates to a camera assembly.

6. A camera assembly, for a vehicle,
comprising a first camera; - and
a second camera for capturing respective images, wherein respective fields of view of the two cameras overlap at least in a partial region, and including at least one evaluation device, by means of which at least in an image captured by the first camera at least one contamination region including a plurality of pixels is detectable within the partial region, wherein the camera assembly includes an image processing device, by means of which data values specifying the respective transparency of the pixels in the at least one contamination region are alterable with respect to respective reference values increasing towards an edge of the respective image upon superimposition of the images in the partial region, wherein in the respective image captured by the second camera, the data values specifying the respective transparency of pixels in an image region superimposed with the at least one contamination region are decreased with respect to the respective reference values, and wherein that the data value of a pixel specifying the transparency in the image captured by the first camera is increased by an amount, by which the data value of a pixel superimposed with this pixel in the image captured by the second camera is decreased. - View Dependent Claims (7)
