    Abstract: A headlamp control device configured to control a headlamp which illuminates forward of a vehicle, is provided. The device includes a visibility detector configured to detect visibility of a road state forward of the vehicle, and a headlamp controlling module configured to control brightness of the headlamp. The headlamp controlling module is able to adjust light emitted from the headlamp so that a brightness gradient that is a difference of brightness of a part distant from the vehicle and brightness of a part closer to the vehicle is changed. When a deterioration in the visibility is detected, the headlamp controlling module executes a brightness adjusting control in which the brightness gradient is increased by making the brightness of the part closer to the vehicle higher than the brightness of the part distant from the vehicle, as compared with the brightness gradient when the deterioration in the visibility is not detected.

  • Patent number: 11285779
    Abstract: An image capturing unit captures a periphery of a moving body through a transmitting portion. A heater is capable of heating the transmitting portion. An air-conditioning unit switches an air-conditioning state in the moving body between an inside air circulation state and an outside air introduction state. A control unit controls the heater. The control unit can make the heater operate intermittently, and perform control so that an OFF time of the heater during an intermittent operation will be shorter in the case in which the air-conditioning state is set to the inside air circulation state than the case in which the air-conditioning state is set to the outside air introduction state.

  • Patent number: 11282224
    Abstract: A target object detection section detects the region of an image of a target object from a frame image captured as a moving image. A contour search section samples the values of pixels in four diagonal directions in a pixel array, using as a start point a pixel of which the corresponding element targets G (green) for observation in the region. The contour search section then detects coordinate point candidates on a contour line of the target object on the basis of changes in luminance Y of the sampled pixels. The contour search section filters the coordinate point candidates based on luminance changes in the color component of the target object. The contour search section causes the distribution of the coordinate points to approximate the contour line. A position information generation section acquires position information regarding the target object in the real space using the gravity center and size of the target object image obtained from the contour line.

  • Patent number: 11284025
    Abstract: A digital pixel includes a capacitive transimpedance amplifier (CTIA) coupled to a photodiode that receives an electrical charge and output an integration voltage. An integration capacitor coupled to the CTIA accumulates the integration voltage over an integration period. A comparator compares the accumulated integration voltage with a threshold voltage and generates a control signal at a first level each time the accumulated integration voltage is greater than the threshold voltage. A charge subtraction circuit receives the control signal at the first level and discharges the accumulated integration voltage each time the control signal at the first level is received from the comparator. An analog or digital counter receives the control signal at the first level and adjusts a counter value each time the control signal is received from the comparator. An output interface communicates the counter value to an image processing circuit at an end of the integration period.
