An image capturing apparatus comprising; projection means for projecting a first or second pattern each having a bright and dark portions onto a target object as a projection pattern; and image capturing means for imaging the target object on an image sensor as a luminance distribution. The luminance distribution has a first luminance value corresponding to the bright portion and a second luminance value corresponding to the dark portion, the first and second patterns have an overlapping portion where positions of the bright or dark portion overlap, a first luminance distribution corresponding to the first pattern and a second luminance distribution corresponding to the second pattern have an intersection at which the luminance distributions have the same luminance value, and the luminance value at the intersection differs from an average value of the first and second luminance values by a predetermined value. |
