<p>PROBLEM TO BE SOLVED: To calculate illuminance distribution when plural light emitting elements emit light at the same time, on the basis of a brightness value.SOLUTION: A brightness value of light from each of plural light emitting elements is acquired. The brightness value, information on the distribution of light emitted by one light emitting element that is the light emitting element of the same kind as the plural light emitting elements, and information on the arrangement of the plural light emitting elements are used to calculate illuminance distribution when the plural light emitting elements emit light at the same time.</p> |
