PURPOSE: To relax a distortion of an image without causing any increase in the cost of the device and to cape with the variance of lenses and temperature characteristics, etc. CONSTITUTION: This device is equipped with a lens 101 consisting of a wide-angle lens or fisheye lens having barrel-shaped distortion, a CCD camera which converts light obtained by picking up an image through the lens 101 into an electric signal through photoelectric conversion and outputs it as an image signal, a coordinate converter 104 which inputs the image signal from the CCD camera and converts the coordinates of the image signal in pixel units by using a nonlinear odd function, and a display monitor 107 which displays an image. Here, 103 is an A/D converter, 105 is an image memory, and 106 is a D/A converter. |
