Claim Text:
1. An information processing apparatus comprising: a projection unit configured to project one of a first luminance pattern and a second luminance pattern that has a different luminance distribution on a measurement object; an image capturing unit configured to form the pattern projected on the measurement object onto an image sensor as a tone distribution, output a maximum tone value for each tone point at which exposure exceeds a saturation light amount, and output a tone value corresponding to exposure for each tone point at which exposure is less than or equal to the saturation light amount; a calculation unit configured to calculate individual tone intersections by interpolating a tone distribution of the first luminance pattern and a tone distribution of the second luminance pattern that were output by the image capturing unit; and a light quantity adjustment unit configured to adjust the quantity of light that enters the image sensor such that the tone values of tone points that are adjacent to the tone intersections and are used in calculation of the individual tone intersections are lower than the maximum tone value, and the tone value of at least one tone point other than the adjacent tone points is equal to the maximum tone value.
