According to one embodiment, a light source control apparatus controls a light source emitting phosphorescence. The light source control apparatus includes a driver configured to supply a drive pulse to the light source. The driver is configured to generate a first drive pulse comprising constant amplitude and a pulse width based at least in part on the lighting value and a second drive pulse comprising a constant pulse width and amplitude based at least in part on the lighting value. The driver is configured to supply the first drive pulse or the second drive pulse to the light source in accordance with the lighting value.
