ABSTRACT:
A projection equipment is provided with a projection system, a memory unit for storing discrimination information which is used to judge whether or not a cooling operation of a light source lamp of the projection system has been finished in a normal manner at the time of a previous power-off operation, a key input unit for giving an instruction to execute a power-on operation, and a control unit adapted to use a timer unit for delaying a turn-on operation of the light source lamp by a predetermined time depending on the discrimination information stored in the memory unit at the time when the instruction to execute the power-on operation is given.
