ABSTRACT:
After gain correction acquisition images are collected, an image reading apparatus calculates any deviation between the grid direction and the pixel line-up direction of a solid-state imaging element (12) in the rotation direction in the grid direction calculation process, and the deviation of a grid (11) in the rotation direction is corrected by accurately aligning the grid direction in the gain correction acquisition image to have a given relationship with respect to the pixel line-up direction, thus photographing an image in practice.
