一种投影机，包括一环境侦测模组以及一处理模组。环境侦测模组于一第一时间侦测一预定环境资讯及于一第二时间侦测一即时环境资讯。处理模组与环境侦测模组耦接，接收预定环境资讯及即时环境资讯，并执行一开机方法，开机方法包括以下步骤：储存预定环境资讯，并定义预定环境资讯为比对基准；及比对预定环境资讯与即时环境资讯，其中，当预定环境资讯与即时环境资讯实质上相同，执行一开机程序，当预定环境资讯与即时环境资讯实质上不相同，输出一授权指令请求。本发明另提供一种投影机的开机方法。; A projector includes an environmental detecting module and processing module. The environmental detecting module detects a predetermined environmental information at a first time and a real-time environmental information at a second time. The processing module couples to the environmental detecting module, and the processing module accepts the predetermined environmental information and the real-time environmental information, and the processing module processes a boot up method. The boot up method includes the following steps of saving and defining the predetermined environmental information as comparison reference; and comparing the predetermined environmental information and the real-time environmental information, when the predetermined environmental information and the real-time environmental information is substantially the same, processing a boot up program, and when the predetermined environmental information and the real-time environmental information is substantially different, outputting an authorization request. The present invention also discloses a boot up method of a projector. |
