An imaging device model system and a method are provided for adjusting an image which may allow a driver to receive an image having a minimized blind spot using a converted image and to view a wider range of the image without distortion using an imaging device. The system includes an imaging device that is configured to capture real images of sides and a rear of a vehicle. The system also includes an input unit configured to move, expand, or reduce the real images and a imaging device model unit that is configured to project the real images onto a projection surface to generate virtual viewpoint images and then convert parameters of the virtual viewpoint images to generate converted images. In addition, an output unit is configured to output the converted images.
