Abstract:
1. An image processing apparatus 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 image processing apparatus comprising: an overlap detecting means for detecting an overlap portion of a first picture and a second picture within the wide-angle picture; a comparing means for comparing pixel values between pixels of the first and second pictures in each of the overlap portions within the wide-angle picture; a splicing means for performing a splicing by shifting the overlap portions based on the comparison by the comparing means; a difference calculating means for calculating the absolute value of differences in pixel values, for each color component, between the first and second picture pixels identical in position on the wide-angle picture in each of the overlap portions, wherein the comparing means compares the sum of the absolute values from all of the overlap portions with a first predetermined threshold; and a logarithm transformation means for performing a logarithm transformation of the sum, wherein the comparing means compares the logarithm transformation of the sum with a second predetermined threshold.
