Abstract
An apparatus includes a unit computing, at each of positions on a target, first products of first reference values for light sources and factors for light sources, and a first sum of the first products corresponding to the light sources, and estimating, at each of the positions, the first sum as a first component at each of the positions, each of the first reference values being obtained referring to a first distribution, a unit computing a second sum of the factors for all of the light sources, and a second product of the second sum and second reference value, and estimating, at each of the positions, the second products as a second component at each of the positions, the second reference value being obtained referring to a second distribution that has a spatially constant value, and a unit computing a third sum of the first component and the second component.
