A vehicle periphery monitoring device for monitoring the periphery of a vehicle, comprising: an imaging unit that obtains a peripheral image of a left rear side of the vehicle and a peripheral image of a right rear side of the vehicle by imaging the periphery of the vehicle; a display unit that displays the peripheral images imaged in the imaging unit as separate from one another rather than as combined; and an image control unit that controls the peripheral images displayed in the display unit, characterized in that the image control unit varies a distance between the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle which are displayed adjacent to each other on the display unit, and an angle of view representing an imaging range with an angle in each of the peripheral image of the left side of the vehicle and the peripheral image on the right side of the vehicle, wherein when the traveling situation of the vehicle is is a street traveling, a parking traveling, a traveling on a rainy day, or a traveling at night, the angle of view of each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a narrow angle, and when the traveling situation of the vehicle is is a high-speed traveling or a turning traveling, the angle of view of each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a wide angle, the distance between the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is set as a first distance when the angle of view in each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a narrow angle, the distance between the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is set as a second distance smaller than the first distance when the angle of view of each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a wide angle, and the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle correspond to a pair of vehicle peripheral environments reflected in a left side mirror or a right side mirror. an imaging unit that obtains a peripheral image of a left rear side of the vehicle and a peripheral image of a right rear side of the vehicle by imaging the periphery of the vehicle; a display unit that displays the peripheral images imaged in the imaging unit as separate from one another rather than as combined; and an image control unit that controls the peripheral images displayed in the display unit, characterized in that the image control unit varies a distance between the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle which are displayed adjacent to each other on the display unit, and an angle of view representing an imaging range with an angle in each of the peripheral image of the left side of the vehicle and the peripheral image on the right side of the vehicle, wherein when the traveling situation of the vehicle is is a street traveling, a parking traveling, a traveling on a rainy day, or a traveling at night, the angle of view of each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a narrow angle, and when the traveling situation of the vehicle is is a high-speed traveling or a turning traveling, the angle of view of each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a wide angle, the distance between the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is set as a first distance when the angle of view in each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a narrow angle, the distance between the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is set as a second distance smaller than the first distance when the angle of view of each of the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle is a wide angle, and the peripheral image of the left rear side of the vehicle and the peripheral image of the right rear side of the vehicle correspond to a pair of vehicle peripheral environments reflected in a left side mirror or a right side mirror.
