3. A computer-readable media storing a program for causing a computer to execute a method for generating a wide-angle picture by overlapping three or more pictures captured at different visual points, each picture including a part of at least one other picture, the method comprising:
detecting an overlap portion of a first picture with a second picture within the wide-angle picture;
comparing pixel values between pixels of the first and the second pictures in each of the overlap portions in the wide-angle picture;
performing a splicing by shifting the overlap portions based on the comparison obtained by a processing in the comparison step;
calculating the absolute value of differences in pixel values, for each color component, between the first and the second picture pixels identical in position on the wide-angle picture in each of the overlap portions;
calculating the median value, for each color component, of the absolute values; and
comparing the sum of the median values with a predetermined threshold.
