Abstract
A method includes receiving, via. a. user interface of a computing device, input indicating target illuminances that correspond to surfaces of an object, determining, via the computing device, power levels for compensatory light sources based on the target illuminances and positions and orientations of the surfaces with respect to the compensatory light sources, and causing, via. the computing device, the compensatory light sources to operate according to the power levels.
Claims20
A method comprising:
- receiving, via a user interface of a computing device, input in the form of information that corresponds to surfaces of an object;
- determining, via the computing device, power levels for compensatory light sources based on the information and positions and orientations of the surfaces with respect to the compensatory light sources;
- and
- causing, via the computing device, the compensatory light sources to operate according to the power levels,
- wherein receiving the input comprises receiving the input such that the input indicates positions, orientations, and/or power levels of one or more background light sources, and wherein determining the power levels for the compensatory light sources comprises determining the power levels for the compensatory light sources additionally based on the positions, the orientations, and/or the power levels of the one or more background light sources,
- wherein the surfaces comprise a first surface and one or more second surfaces, the method further comprising:
- detecting, via a photosensor, a maximum illuminance corresponding to the first surface, wherein the maximum illuminance is generated by the one or more background light sources and is greater than any illuminance corresponding to the one or more second surfaces and generated by the one or more background light sources,
- wherein receiving the input comprises receiving a request to illuminate each of the one or more second surfaces with the maximum illuminance, and
- wherein determining the power levels comprises determining the power levels such that the power levels accommodate the request.

- wherein receiving the input comprises receiving a request to illuminate the second surface with the maximum illuminance and illuminate the third surface as little as possible, and
- wherein determining the power levels comprises determining the power levels such that the power levels accommodate the request.
