Abstract
A phase modulator of the present disclosure includes a phase distribution arithmetic unit that generates, in a case of reproducing the same reproduction image over a plurality of frames or a plurality of subframes by a light phase modulation element, target phase distribution data that is allowed to reproduce the same reproduction image in at least two adjacent frames among the plurality of frames or in at least two adjacent subframes among the plurality of subframes and that changes phase distribution in the light phase modulation element.
