An apparatus for visually confirming a vehicle periphery includes a camera device which is attached to a vehicle, and which picks up a image in at least one direction at the vehicle periphery and a display unit which displays the picked-up image in the at least one direction on a display unit installed in the vehicle. The camera device is attached to the vehicle while a position of the camera device is inclined, so that a vehicle is at least partially taken in the picked-image in the at least one direction, The image-processing device carries out a rotation process with respect to the picked-up image, in which a scene taken in the picked-up image is inclined due to an inclination resulting from the position of the camera device, so that an inclination of the scene is negated, and which displays the scene in the display unit.
