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.

The present invention relates to a lamp system including a digital micro-mirror device (DMD) module, and more particularly, to a system and method for improving life characteristics of a DMD module. A DMD lamp and a method of controlling a DMD lamp of the present invention may improve a life of a DMD module by measuring a temperature of the DMD module in real time and controlling operations of the DMD module and a light source when the temperature of the DMD module rises above a certain temperature, and improve the life of the DMD module by adjusting a ratio of an ON mode/OFF mode of the DMD module to the same ratio and automatically compensating for the insufficient amount of light to reduce the consumption of an angle adjusting unit of a mirror to a minimum while maintaining the output amount of light.

A method for operating a headlight system of a motor vehicle, which during operation, illuminates an overall illumination area in the area surrounding the motor vehicle. At least two sensors are provided which detect objects in different associated sensor regions, the sensor regions of the sensors overlapping in an overlap region within the overall illumination area. The data of the sensors are fused to ascertain the existence of an object in the overlap region. Upon confirmation of the existence of the object, a zone in the overall illumination area in which the object is located is selectively excluded from illumination. A motor vehicle having a headlight system operated in this manner is also described.

A system includes a server that stores pest data for each region, and a vehicle control device that receives pest data related to a current location of the vehicle from the server, and controls at least one of a sound output device or a lighting device according to driving or stopping based on the pest data received from the server. The system may actively prevent pests from approaching the vehicle according to the location and driving conditions of the vehicle to improve driver satisfaction and prevent the vehicle from being damaged.

The present disclosure relates to a device and a method for controlling a vehicle. The device may include a camera for obtaining an image of a region around the vehicle and outputting image information, a navigation for outputting a current location of the vehicle as map information, a front radar for sensing an object in front of the vehicle and generating front radar information, a front-lateral radar for sensing an object in front of and lateral to the vehicle and generating front-lateral radar information, a lamp controller that generates a shadow zone code based on at least one of the image information, the map information, the front radar information, or the front-lateral radar information, and a lamp for forming a shadow zone in a light irradiation pattern based on the shadow zone code.

Systems, apparatus, methods, and computer program products to enhance the operation of a light system. A light apparatus includes an optical member to project light, one or more elastically deformable position adjustment members, and one or more light sources. The elastically deformable position adjustment members are operable to adjust a mounting position of the optical member, and include one or more photochromatic regions to facilitate movement of the one or more elastically deformable position adjustment members from a contracted state to an expanded state in response to exposure to UV light. The one or more light sources operable to selectively emit illuminating UV light in a direction that contacts the one or more photochromatic regions to thereby adjust a mounting position of the optical member and change a direction of light emitted by the lighting apparatus.

A light distribution control device including: an acquirer acquiring information representing a running status of an assistance operation performed for driving assistance from a driving assistance device performing driving assistance of a subject vehicle based on a recognition result of objects disposed in front of the subject vehicle recognized based on detection results acquired by a plurality of sensors including an optical sensor; and a light distribution controller performing light distribution control including change of an output level of a headlight of the subject vehicle, in which the light distribution controller gently performs change of the output level of the headlight in accordance with running of the assistance operation in the light distribution control.

A method for providing sound detection information includes steps of: sensing sound around a host vehicle to generate sound data; generating a result of sound detection based on the sound data; calculating a rate of change based on the result of sound detection; generating a result of tunnel detection by comparing the rate of change with a threshold; and controlling at least one peripheral apparatus in the host vehicle according to the result of tunnel detection.

A method, executed by a computer, includes receiving extent information for a light zone and a desired emitted light level for a light source proximate to the light zone where the light source is a programmable light source, determining that the light source projects light onto the light zone, and adjusting, by one or more processors, the light source to emit the desired emitted light level. A computer system and a computer program product corresponding to the method area also disclosed herein.

Provided are an auto-regulated vehicle headlamp, an automatic regulation method and a vehicle. The auto-regulated vehicle headlamp includes: a projector assembly capable of projecting infrared rays, configured to project infrared stripes onto a traveling road-surface; the infrared stripes being constituted by alternate bright and dark stripes so that corresponding distorted stripes can be formed when an object, during appearing or disappearing on the traveling road-surface, has a changed contour; a camera configured to capture image information on the distorted stripes; an image processor in data connection with the camera and configured to acquire the image information and generate a headlamp control command accordingly; a matrix headlamp including a plurality of LED light sources; and a first controller in data connection with the matrix headlamp and the image processor, configured to acquire the headlamp control command and adjust the number of the LED light sources to be activated and their brightness.
