Abstract: Provided is a projecting apparatus including a projector that emits projection light, a processor that controls an operation of the projector, and a user operation receiver that receives an input operation. In receipt of the input operation concerning startup of the projecting apparatus, the processor assesses a state of the projecting apparatus and determines whether a lighting action of the projection light from the projector is valid based on an assessment result of the state of the projecting apparatus.

Abstract: A projection apparatus includes a storage unit configured to store an image signal input via the input unit, a comparison unit configured to compare an image signal input via the input unit with an image signal already stored in the storage unit and determine one of coincidence and inconsistency between the compared two image signals, a time-measurement unit configured to measure a time of a state in which coincidence between the compared two image signals is determined by the comparison unit, a determining unit configured to determine whether or not a time-measurement result by the time-measurement unit exceeds a preset time, and a projection control unit configured to variably set the light-emission luminance of the light source to be lowered according to a determination result of the determining unit.
