Disclosed is a light source control apparatus which controls a plurality of light sources; wherein a luminance can be independently controlled for each of the plurality of light sources by changing a ratio between a turned-on period and a turned-off period; the light source control apparatus comprising a determining unit configured to determine the respective luminances of the plurality of light sources and to determine, as a light source driving condition, a length of the turned-on period of each of the plurality of light sources and a turn-on reference timing as a start timing of the turned-on period; a correcting unit configured to perform correction for the light source driving condition to lower the luminance(s) of at least one of the plurality of light sources so that an electric power consumption is not more than a threshold value at all of the turn-on reference timings.
