1. A projection controlling apparatus comprising:
processing circuitry configured to
determine whether a hand-held object that is an object held by a hand is present in a captured image represented by captured image data generated by capturing a projection region onto which a projector projects a projected image, the hand-held object being a device with a display or including viewable or readable content; and
prohibit the projected image from being projected onto the hand-held object in the projection region in response to a determination by the processing circuitry that the hand-held object is present in the captured image.
