Embodiment Construction

[0031] figure 1 A schematic diagram of a vehicle 100 according to one embodiment of the invention is shown. Vehicle 100 has camera 102 , image evaluation device 104 and driver assistance system 106 . Another vehicle 110 is located in the area ahead of vehicle 100 . The further vehicle 110 has red tail lights 112 . Driver assistance system 106 is a system for which the identification of taillights 112 of other vehicle 110 is of major relevance. Here, taillight 112 shall represent an object of any color whose color is relevant for any system 106 of vehicle 100 .

[0032]If further vehicle 110 is located in the detection range of camera 102 , camera 102 can generate an image in which rear lights 112 are imaged. According to this embodiment, the light emitted by the taillight 112 is detected by the camera 102 . Image evaluation device 104 is designed to evaluate the images of camera 102 in order to determine image regions in which rear lights 112 are imaged. If various brigh...

Abstract

The invention relates to a method for adapting a filter property of an adaptive color filter (223) of a pixel (220) of an image sensor of a camera (102). The method comprises a step of determining (445) a required detection property of the pixel, a step of determining (447) a required filter property of the color filter in order to realize the required detection property of the pixel, and a step of providing (449) a setting signal for setting the filter property of the color filter according to the required filter property.

Description

technical field [0001] The invention relates to a method for adapting the filter properties of an adaptive color filter of an image point of an image capture device of a camera, a method for operating an image capture device of a camera of a vehicle, a corresponding device and A corresponding computer program. Background technique [0002] In order to be able to ascertain color information by means of the camera, different color filters are provided for the different pixels of the image recording device of the camera. However, in order to obtain a color image, interpolation between individual pixels is required. This again leads to a measurement accuracy in the evaluation of the camera images. [0003] Document DE 10254806 B4 shows a method for information processing of at least two information sources in a motor vehicle. Contents of the invention [0004] Against this background, the present invention proposes a method for adapting the filter characteristics of an adap...
