<p>Provided is a light source device that can resolve the problem of the power consumption peak becoming high if there are plural light emitting elements when radiated EMI noise is reduced by defusing the lighting frequencies of light emitting elements. M series generating circuits (102) generate a plurality of pseudo-random number sequences according to assignment information that assigns the plurality of pseudo-random number sequences to determine the lighting timing of the light emitting elements (105). Control signal generating circuits (103) generate a plurality of control signals that indicate the lighting period for the light emitting elements (105) based on the pseudo-random number sequences and plural brightness information for determining the brightness of the light emitting elements (105). Drive circuits (104) light the light emitting devices (105) according to the control signals. A control circuit (101) generates the assignment information such that all of the lighting periods for the light emitting elements (105) are not overlapping at the same time.</p> |
