A vehicle periphery monitoring device includes a first bird's-eye view image generation section generating a first bird's-eye view image through a two-dimensional plane projective transformation based on a photographed image acquired by an in-vehicle camera module, a second bird's-eye view image generation section generating a second bird's-eye view image through a three-dimensional plane projective transformation based on the photographed image, and a displaying image generation section generating a first displaying image for monitor displaying from the first bird's-eye view image and a second displaying image for monitor displaying having a higher displaying magnification than the first displaying image, from a predetermined area of the second bird's-eye view image corresponding to a predetermined area of the first bird's-eye view image.
