Abstract:
1. A lighting apparatus that projects irradiation light toward an irradiation target object having an arbitrary shape, comprising: an irradiation light signal input configured to receive an irradiation light signal; a coating corrector configured to correct the irradiation light signal received by the irradiation light signal input so that the irradiation target object can be coated with the irradiation light when the irradiation light is irradiated onto the irradiation target object; and irradiation light projector configured to project the irradiation light onto the irradiation target object by using the irradiation light signal corrected by the coating corrector, wherein the irradiation light includes coating light that coats the irradiation target object, and background light that becomes a background of the irradiation target object, wherein the coating corrector corrects the irradiation light signal so as to correct an outline of the coating light in the irradiation light, and the coating corrector comprising: a first coating corrector configured to correct the irradiation light signal so as to cut the outline of the coating light in the irradiation light in conformity with the shape of the irradiation target object; and a second coating corrector configured to correct the outline of the coating light, the outline being corrected by the first coating corrector, in response to a positional relationship between an origin position of the irradiation target object and the irradiation light projector.
