An image conversion device is provided. The device includes a driving environment recognition unit that has a camera acquiring a base image of areas behind and to the side of a subject vehicle and a sensor sensing a driving environment behind and to the side of the subject vehicle. A display unit displays the base image and a navigation unit provides information regarding a location of the subject vehicle. A controller determines whether a blind spot is created in the driving environment based on information acquired from the driving environment recognition unit and the navigation unit, converts the base image into an image including the blind spot to generate the converted image, and operates the display unit to display the converted image.
