  • Publication number: 20230236290
    Abstract: A LIDAR sensor for detecting at least one object in a field of view. The LIDAR sensor includes: a transmitting unit includes a laser source; and a receiving unit having at least one detector unit for receiving secondary light that has been reflected and/or scattered in the field of view by an object. The detector unit includes a sub-detector array including a plurality of sub-detectors arranged in a first direction of extent next to each other and/or in a second direction of extent one behind another, and a processor unit that is designed to select a first group from a plurality of sub-detectors and to group it to form a first macropixel, and simultaneously to select at least one second group and to group it/them to form at least one second micropixel. The first macropixel and at least one of the second macropixels comprise at least one same sub-detector.

  • Patent number: 9832356
    Abstract: A camera module, in particular for a vehicle, the camera module having at least: an objective having a lens mount and at least one lens, an image sensor for acquiring and converting optical signals into electrical signals, a bearer device on which the image sensor is mounted and contacted, and a camera housing for accommodating the objective and the bearer device. The objective is connected to the camera housing, in particular to a first housing part, and is borne by the camera housing. The bearer device can in particular be fixed on the objective or on the first housing part.

  • Patent number: 8743202
    Abstract: A device is described for a motor vehicle, having at least one first camera and at least one second camera, the first camera and the second camera acting as a stereo camera, the first camera and the second camera being different with respect to at least one camera property, in particular the light sensitivity of the first camera and the light sensitivity of the second camera being different. Furthermore the device is configured in such a way that the driver assistance function of night vision support and/or traffic sign recognition and/or object recognition and/or road boundary recognition and/or lane recognition and/or other functions are ensured.

  • Patent number: 7889231
    Abstract: An image-recording system having at least one camera, having a receiving device and having a signal connection between the camera and the receiving device. The receiving device generates a PWM-coded signal which is transmitted to the camera. A clock signal is obtained in the camera from the PWM-coded signal.

  • Publication number: 20100134616
    Abstract: A color mask for an image sensor of a vehicle camera has a matrix arrangement made up of first filter pixels and second filter pixels. In every horizontal row and/or every vertical column, first filter pixels and second filter pixels are situated, the first filter pixels and the second filter pixels having different transmission behaviors. The second filter pixels have a more comprehensive transmission behavior, e.g., completely transparent to optical light. The first filter pixels are preferably red.

  • Publication number: 20060228024
    Abstract: A method and a processing unit for adjusting the characteristic curve of the exposure sensitivity of at least one pixel of at least one image sensor in a motor vehicle are described. The optimal characteristic curve of the exposure sensitivity is determined from the histogram of the gray values of at least one image as a function of image signals from at least one image sensor. The freely definable characteristic curve of the image sensor having linear segments is chosen so that it agrees at least approximately with the optimal characteristic curve. Along with the size and/or the position of the characteristic curve of the exposure sensitivity, alternatively or in addition the shape of the characteristic curve is adjusted.
