PROBLEM TO BE SOLVED: To properly manage an exchange period of a lamp. SOLUTION: When a lamp serial code belonging to an exchanged lamp is input, a projector judges the validity by executing check sum confirmation processing (step S3 Yes, S4). When the projector confirms that it is a valid code (step S5 Yes), the projector automatically resets a lamp timer T (T=0), and starts lamp timer operation processing (step S11, S12). Thereafter, the projector displays a lamp exchange alarm when the lamp timer T reaches a value based on a nominal life time included in the lamp serial code. The invention can be applied to a digital cinema projector. COPYRIGHT: (C)2008,JPO&INPIT |
