1. An information processing apparatus, comprising:

  • an orientation detection unit configured to detect an orientation of a lens in a lens unit of an image projection unit;

    wherein the lens unit is rotatable independently of a chassis orientation of the information processing apparatus;

    an acceleration sensor in the lens unit, wherein the sensor detects an orientation of the lens in the lens unit with respect to a direction of gravitational force;

    a control unit configured to perform control not to turn on the image projection unit (i) when the lens of the image projection unit is in an exposed state whereby the lens is exposed to an environment external to the apparatus, and (ii) when an angle between the orientation of the lens detected by the orientation detection unit and a vertical direction falls within a preset angular range; and

    the control unit is further configured to enable image projection (i) when the lens of the image projection unit is in an exposed state whereby the lens is exposed to an environment external to the apparatus, and (ii) when an angle between the orientation of the lens detected by the orientation detection unit and a vertical direction falls outside of the preset angular range;

    the control unit is further configured to enable automatic off-operation of the image projection unit during rotation of the lens unit to protect the lens.
