20090026482 | Optoelectronic Component - An optoelectronic component having a basic housing or frame and at least one semiconductor chip, specifically a radiation-emitting or-receiving semiconductor chip, in a cavity of the basic housing. In order to increase the efficiency of the optoelectronic component, reflectors are provided in the cavity in the region around the semiconductor chip. These reflectors are formed by virtue of the fact that a filling compound filled at least partly into the cavity is provided, the material and the quantity of the filling compound being chosen in such a way that the filling compound, on account of the adhesion force between the filling compound and the basic housing, assumes a form which widens essentially conically from bottom to top in the cavity, and the conical inner areas of the filling compound serve as reflector. | 01-29-2009 |

20120127311 | METHOD FOR CALIBRATING AN IMAGE RECORDING SYSTEM IN A MOTOR VEHICLE - A method for calibrating an image recording system in a motor vehicle, image data being recorded via a camera system from an area which is illuminated by a lighting unit of the motor vehicle, and a modulation of the radiation emitted by the lighting unit being performed to determine the illuminated area. | 05-24-2012 |
20130027560 | Color mask for an image sensor of a vehicle camera - A color mask for an image sensor of a vehicle camera, the color mask having a matrix configuration of filter pixels having different spectral transmission behaviors, some filter pixels being transparent filter pixels, which are at least essentially uniformly transparent for optical light, and additional filter pixels being color pixels having a wavelength-selective transmission behavior, the color mask having a color pattern as a repeating configuration of filter pixels having a specific transmission behavior. The color mask has a central area having a first color pattern and a lower area and/or an upper area having a second color pattern, the first color pattern and the second color pattern being different, and the first color pattern containing transparent filter pixels. | 01-31-2013 |
20130039576 | METHOD AND DEVICE FOR ANALYZING AN IMAGE OF AN IMAGE RECORDING DEVICE FOR A VEHICLE - In a method for analyzing an image of an image recording device for a vehicle, a piece of brightness information of the image is determined, taking an exposure characteristic of the image recording device into account, and a threshold value is set as a function of the piece of brightness information. An image structure of the image is furthermore determined, and a blindness value for the image is determined on the basis of the image structure, using the threshold value. | 02-14-2013 |
20130308020 | METHOD AND DEVICE FOR ESTIMATING A FLY SCREEN EFFECT OF AN IMAGE CAPTURE UNIT - A method for estimating a fly screen effect of an image capture unit is described, having a plurality of image sensors for providing an item of light intensity information. The method includes a step of determining an image property of an item of image information, based on a plurality of items of light intensity information and on a plurality of parameters, each of the plurality of parameters being associated with each of the plurality of image sensors.
