1. An information processing apparatus comprising:

  • a data generation unit configured to sequentially generate projection patterns;

    a projection unit configured to project a projection pattern onto a target object every frame;

    a trigger signal generation unit configured to generate a trigger signal when it is detected that the projection pattern of the current frame to be projected onto the target object is different from the projection pattern of a previous frame;

    an imaging unit configured to image the target object, onto which the projection pattern is projected, according to the trigger signal; and

    a shutter signal generation unit configured to output a shutter signal to the imaging unit at a preset timing, according to the trigger signal generated by the trigger signal generation unit,wherein the imaging unit images the target object, onto which the projection pattern is projected, according to the shutter signal.
