Patent number: 9261757Abstract: A projector can not only perform power on/off operation in synchronization with open/close action of a shutter but also provide a screen mute function achieved by the shutter. When the shutter is located in an OFF position and the period timed by a timer is longer than or equal to a predetermined period during the operation of the projector, the projector is powered off. In this process, after the timing operation performed by the timer and notification from a notification unit are terminated, a light source is turned off and the projector is caused to enter a standby state.Type: GrantFiled: August 8, 2013Date of Patent: February 16, 2016Assignee: SEIKO EPSON CORPORATIONInventor: Takashi Ozawa
