    Abstract: PROBLEM TO BE SOLVED: To control a continuously variable head lamp so as to be properly operated over a broad range of ambient light conditions. SOLUTION: This continuously variable head lamp has an effective illumination range by changing at least one parameter selected from a set including an aim horizontal direction, an aim vertical direction, and projected illumination. A system for automatically controlling the continuously variable head lamp mounted in a vehicle includes an imaging system which can determine the position of the lateral direction and height of a head lamp of an incoming vehicle and a tail lamp of an antecedent vehicle. This system further includes a control unit which can capture an image from the front face of the control vehicle. This image covers a glare area including a point where a driver in an incoming or antecedent vehicle perceives the head lamp and causes an excessive level of glare. When at least one vehicle is within the glare area, the illumination range of the head lamp is narrowed. COPYRIGHT: (C)2004,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a control circuit for controlling various functions of an image array sensor such as an active pixel image array sensor. SOLUTION: The present invention relates to a control system for controlling an image array sensor and controlling communication between the image array sensor and a microcontroller by way of a serial communication interface. The control system is able to efficiently control various aspects of the image array sensor such as windowing, mode of operation, sensitivity as well as other parameters in order to reduce the data throughput. An important aspect of the invention relates to the fact that the control circuit can be rather easily and efficiently configured in CMOS with relatively few output pins which enable the control circuit to be rather easily and efficiently integrated with CMOS based on the image array sensor and even the microcontroller to reduce the part count and thus, the overall cost of the system.

    Abstract: PROBLEM TO BE SOLVED: To provide a lamp capable of reducing the glare of embarrassing a driver of a leading vehicle. SOLUTION: A sensor array 52 and a control unit 44 are included in a system 40 for controlling at least one vehicular exterior lighting fixture 22 of a control object vehicle. The sensor array 52 can detect a light level in front of the control object vehicle. The control unit 44 communicates with the sensor array 52 and at least the one vehicular exterior lighting fixture, and measures a distance and an angle up to the leading vehicle from at least the one vehicular exterior lighting fixture of the control object vehicle. The control unit 44 controls operation of at least the one vehicular exterior lighting fixture as a function of the distance and the angle based on output from the sensor array 52. At least the one vehicular exterior lighting fixture 22 can operate so as to prevent impartment of the glare of embarrassing the driver of the leading vehicle. COPYRIGHT: (C)2009,JPO&INPIT
