Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a driving assistance device, and more particularly, to a driving assistance device capable of securing a driver's view from sunlight.
Generally, a sun visor is installed on a front upper surface of a driver's seat or an assistant seat to shield sunlight transmitted from the front surface of the vehicle. The sun visor is used to prevent the sunlight from interfering with the field of view when the sun is in front of the vehicle.
If the sun is in front of the driver during driving, the driver visually checks the sun visor to ensure visibility due to sunshine.
However, the sun visor can block the sunlight to ensure visibility, but it is difficult to ensure the visibility of the sun visor.
In recent years, a technique has been developed in which an area covered by a sun visor is captured through a camera and displayed on a sun visor so as to secure an obscured view.
However, the method of photographing the area obscured by the sun visor and displaying it on the sun visor can secure a field of view obscured by the sun visor, but there is still a problem in that sun visibility due to sunlight still occurs when the sun is located in front of the vehicle have.
In order to prevent this problem, sun visors are conventionally used for sun visors to alleviate the visual disturbance. However, since the brightness is uniformly reduced, the bright areas are also darkened and the field of view is limited.
The embodiment of the present invention is intended to provide a driving assistance device that more effectively prevents eye blindness due to sunlight, while securing a field of view for an area obscured by the sun visor.
