摘要
Up and down directions of an image are to be precisely judged without a special equipment installed in an image pickup device. An object candidate detecting means detects object candidates from an input image and their angles in the input image. A similarity calculation means calculate the degree of similarity between each detected object candidate and each object stored in advance. An input image angle calculating means judges up and down directions of the input image based on the calculated similarity of each object candidate and the angle of the input image. The input image angle calculating means carries out weighting for the angle of each object candidate in the input image based on its similarity and calculates slant angles with respect to the up and down directions of the input image by using the weighted angles.
