PROBLEM TO BE SOLVED: To provide a new control method for a light-emitting part and a light-modulating device for a projector. SOLUTION: A frame period includes a plurality of sub-periods, and each sub-period includes a plurality of color periods. A control part of the projector allows the light-emitting part to emit a plurality of color light sequentially in the plurality of color periods in each sub-period. The control part also controls the modulating state of a plurality of light-modulating elements, included in the light-modulating device according to a plurality of pixel data. Specifically, the modulating state of the light-modulating elements in the specific color period in each sub-period is controlled, according to the specific color data included in the pixel data. A first kind of ON period, in which the light modulating elements can be set into the ON state in the specific color period of the first kind of sub-period, is set shorter than a second kind of ON period in which the light-modulating elements can be set into the ON state in the specific color period of the second kind of sub-period.
