Abstract: A night-vision device is provided with a projection unit, an image pickup unit, a luminance ratio determining unit, and a projection control unit. The luminance ratio determining unit determines whether a determination luminance ratio in a set region is within a predetermined luminance range as a luminance ratio at which a subject to be detected forms an emphasized image, said set region having been set at least in a part of an image obtained by means of the image pickup unit. In the cases where the determination luminance ratio is out of the predetermined luminance range, the projection control unit controls the intensity of near-infrared light emitted from the projection unit such that the determination luminance ratio is within the predetermined luminance range.

Abstract: In a display control device, a viewpoint conversion unit converts the viewpoint of images captured by cameras to obtain viewpoint converted images as viewed from above the own vehicle. A steering determination unit determines whether the steering angle of a wheel of the own vehicle is equal to or greater than a predetermined value. When the steering angle is equal to or greater than the predetermined value, an image correction unit creates a corrected image by processing a viewpoint converted image of the wheel in the viewpoint converted image so that the image of the wheel is prevented from being displayed. The image synthesis unit combines the corrected image and the other viewpoint converted images to create a synthesized image. The display control unit displays the synthesized image and an image of the own vehicle on a display device.
