1. An information processing device, comprising:
an adjustment unit configured to shift, with respect to a phase-modulatable range of a phase modulation element, a phase distribution range of light that passes through the phase modulation element,
wherein a difference between a median value of the phase-modulatable range and an average value of the phase distribution range decreases based on the shift of the phase distribution range.
