1. A vehicle periphery video providing apparatus comprising:

  • a first shooting device adapted to shoot a first video of the periphery of a vehicle at a location that is not visible to a driver due to a structural member of the vehicle;

    a second shooting device adapted to shoot a second video of the periphery of the vehicle at the location that is not visible to the driver due to the structural member of the vehicle, the second shooting device being located separately from the first shooting device and;

    a distance detection device adapted to detect a distance to an obstruction present on a shooting direction side of the first and second shooting devices;

    a video processing device adapted for;

    setting a vertical reference surface at a location of the obstruction,performing coordinate conversion on the first and second videos based on (i) the location of the vertical reference surface, (ii) information regarding at least one eye point position of the driver, and (iii) information regarding an installed state of the display device, andproviding a synthesis processed video by performing video synthesis processing on the first and second videos, the synthesis processing comprising;

    comparing pixel values of each pixel of the first video with pixel values of each corresponding pixel of the second video,when a pixel value of a pixel of the first video is the same as a pixel value of a corresponding pixel of the second video, setting the pixel value of the compared pixels as the pixel value of the corresponding pixel in the synthesis processed video, andwhen a pixel value of a pixel of the first video is different from a pixel value of a corresponding pixel of the second video, determining an average of pixel values of peripheral pixels of the compared pixels and setting the average as the pixel value of the corresponding pixel in the synthesis processed video; and

    a display device adapted to display the synthesis processed video, the display device being disposed at a location of the structural member.
