摘要: An image acquiring apparatus for a vehicle includes a light emitting unit configured to emit pulse light to a predetermined direction, an image acquisition unit configured to acquire a plurality of different images of target distance ranges by imaging reflected light returning from the target distance ranges at imaging timings set according to the target distance ranges, and a timing controller configured to control a light emission cycle of the pulse light and the imaging timings. The timing controller is configured to control at least one of the light emission cycle and the imaging timing such that among different target distance ranges, a range of a specific distance necessary for object recognition is imaged with luminance higher than that for ranges other than the range of the specific distance.

摘要: Disclosed is a light source control device including a power conversion unit and a control unit. The power conversion unit includes a transfer capacitor provided between a primary side circuit and a secondary side circuit. The primary side circuit is configured such that a first inductor stores energy when a first switching element is ON. The secondary side circuit is configured such that the second inductor limits a changing speed of the driving current. The power conversion unit is configured such that the driving current is raised when the first switching element is ON. The control unit turns OFF when the magnitude of the driving current exceeds the first threshold value, and turns ON the first switching element when the magnitude of the driving current falls below the second threshold value smaller than the first threshold value.

摘要: A first light source illuminates a first region. A second light source is configured to provide lower luminance than that of the first light source. The second light source illuminates a second region that overlaps the first region, and that has a larger area than that of the first region. A lighting circuit drives the first light source and the second light source according to a common lighting instruction. The lighting circuit gradually turns on the first light source and the second light source with different gradual changing time periods in response to the lighting instruction.
