Projector including light source controlling section for turning light source on and off, control method, control program, and recording medium

Abstract

A control unit of a projector includes a startup information receiving section configured to receive startup information about startup of the projector. A medium judging section of the control unit is configured to judge types of information available on a recording medium. A light source controlling section of the control unit is configured to execute light turn-on control of a light source to emit light after the startup information receiving section receives the startup information, and execute light turn-off control to turn off the light source after execution of the light turn-on control when the type of the information on the recording medium is determined to be exclusively non-visual by the medium judging unit.

1 . A projector, comprising:
 an image projection unit configured to project image light by modulating light emitted from a light source according to information recorded on a recording medium; and   a control unit configured to control the projector, wherein the control unit includes
 a startup information receiving section configured to receive startup information about startup of the projector, 
 a medium judging section configured to judge types of information available on the recording medium, and 
 a light source controlling section configured to execute light turn-on control of the light source to emit light after the startup information receiving section receives the startup information, and execute light turn-off control to turn off the light source after execution of the light turn-on control when the type of the information on the recording medium is determined to be exclusively non-visual by the medium judging unit. 
   
     
     
         2 . The projector according to  claim 1 , wherein the light source controlling section is further configured to execute light turn-off control to turn off the light source when the type of the information on the recording medium is determined to be exclusively used for audio by the medium judging unit. 
     
     
         3 . The projector according to  claim 1 , further comprising a reproduction device configured to reproduce the information recorded on the recording medium, wherein
 the image projection unit projects the image light according to image information reproduced by the reproduction device when the information on the recording medium is determined to be visual by the medium judging unit.   
     
     
         4 . A control method of a projector having an image projection unit configured to project image light by modulating light emitted from a light source according to information recorded in a recording medium, the control method comprising:
 receiving startup information about startup of the projector;   judging types of the information available on the recording medium; and   controlling operation of the light source based on the recording medium judging, wherein the controlling the light source comprises:
 turning on the light source to emit light after receiving the startup information, and 
 turning off the light source after turning on the light source when the type of the information on the recording medium is determined to be exclusively non-visual. 
   
     
     
         5 . A non-transitory storage medium on which a control program of a projector is recorded in such a manner as to be readable by a computer, the projector including an image projection unit which projects image light by modulating light emitted from a light source according to information recorded on a recording medium, the control program comprising:
 a program under which a control unit of the projector executes the control method according to  claim 4 .   
     
     
         6 . A control method of a projector having an image projection unit configured to project image light by modulating light emitted from a light source according to information recorded on a recording medium, the control method comprising:
 receiving startup information about startup of the projector;   turning on the light source to emit light;   judging types of information available on the recording medium; and   turning off the light source after turning on the light source when the type of the information on the recording medium is determined to be exclusively non-visual.
