Abstract
A first points range of high brightness and a second points range of high brightness in a photographed image are selected. It is checked if an identical end point is shared by the three and four points range selected. A first straight line, connecting a center of gravity corresponding to the identical end point and a center of gravity corresponding to another end point of the first points range opposite to the identical end point, is calculated. A second straight line, connecting the center of gravity corresponding to the identical end point and a center of gravity corresponding to another end point of the second points range opposite to the identical end point, is calculated. It is checked if an angle, defined by the first and second straight lines, is within a predetermined limit.
