Changes in ambient light intensity are detected by processing image data from an image capture device to determine, iteratively, a signal-to-noise ratio of the image data. The signal-to-noise ratio is a ratio of average to variance of pixel values for some of the pixels forming the image. A control outputis generated, based on the signal-to-noise ratio, that is responsive to changes in ambient light intensity. The control output is used control a light source of a vehicle.

A gas generator, includes an igniter, a housing provided with a gas discharge port, and including a combustion chamber to burn a gas generating agent, the igniter being shifted from a center of a cluster of the gas generating agent, an isolating part surrounding at least a portion of the cluster of the gas generating agent, and forms, between the isolating part and a predetermined area, a gas flow space serving and a plurality of communicating parts that are provided in the isolating part and connect the combustion chamber and the gas flow space, a portion of the plurality of communicating parts allowing a combustion product generated by combustion of the gas generating agent disposed proximal to the igniter to flow into the gas flow space, and another portion of the plurality of communicating parts allowing a combustion product flowing through the gas flow space to flow out toward the gas generating agent disposed distal to the igniter.

A rearview mirror system for a vehicle providing a direct reflection of scenes in good light and an enhanced display of scenes in bad lighting includes a housing defining an opening, a display screen arranged at the opening, a camera, a fill light lamp, and a controller. The display screen is light-pervious at only one side. The camera and the fill light lamp are arranged on the housing. An image processing chip and the controller are arranged between the display screen and the housing. When ambient brightness is below a preset brightness value, the camera and the fill light lamp are activated, the camera captures images of side and rear scenes of the vehicle and generates an optical signal, the image processing chip, based on the optical signal, outputs an enhanced image on the display screen for better driving safety. A vehicle including the rearview mirror system is also disclosed.

For driver assistance for a combination (8) with a motor vehicle (9) and a trailer (10), a first camera image (19) and a second camera image (20) are generated. A combined image (21) is generated by means of a computing unit (13) by superimposing the camera images (19, 20) such that the second camera image (20) covers a subsection of the first camera image (19), wherein a hitch angle (14) of the combination (8) is determined by means of the computing unit (13). State data of the combination (8) are determined by means of a sensor system (17) and it is determined whether the combination (8) moves forward or backward. The hitch angle (14) is determined based on the state data, if the combination (8) moves forward and based on a change of time-dependent image data, if the combination moves backward. A position of the subsection is determined depending on the hitch angle (14).
