  • Patent number: 10293752
    Abstract: A first capturing image unit mounted on a vehicle body captures an image of surroundings of a work vehicle. A second capturing image unit is disposed above the work implement and captures an image of an area in front of the work implement. A first image generation unit generates, from the image captured by the first capturing image unit, a surroundings composite image, which depicts the surroundings of the work vehicle in a bird's-eye view and is synthesized with a vehicle model depicting the work vehicle. A second image generation unit generates, from the image captured by the second image capturing unit, a work implement composite image, which depicts the area in front of the work implement and is synthesized with the vehicle model and the surroundings composite image. A display unit displays a display image including the vehicle model, the surroundings composite image, and the work implement composite image.

  • Patent number: 10104726
    Abstract: To provide a circuit for reducing an afterglow of secondary light, a circuit includes an LED (11) which includes an LED chip (13) and a KSF phosphor (15), and a first output circuit (5) and a second output circuit (6) which are coupled to a cathode (11C). When a PWM signal goes to “H”, the first output circuit is driven thereby making IF flow from the cathode. When the PWM signal goes to “L”, the first output circuit stops driving, and the second output circuit makes an offset current flow from the cathode.
