Previous studies proposed a smart lighting system that can detect object colors and emit spectrally optimized lighting to reduce the light absorbed by surfaces. The spatial resolution of an absorption-minimization light projection system is investigated using images of various visual complexity. Participants with normal color vision and good visual acuity judged the visual clarity of low, medium, and high complexity images by using a mean opinion score (MOS) scale. Results from the visual assessments show that blur acceptability of illuminated images significantly reduces when the circle of confusion (CoC) is increased by 3%. Blur perception also changes with visual complexity.
