Projector and control method of projector

Abstract

A projector includes: a projection lens which includes a zoom mechanism capable of controlling a projection view angle; a zoom drive unit which drives the zoom mechanism; a zoom amount storing unit which stores a zoom amount provided by the zoom drive unit; an operation signal receiving unit which receives a predetermined operation signal; and a zoom control unit which controls the zoom drive unit in such a manner as to set an initial zoom condition determined based on the zoom amount stored in the zoom amount storing unit when the operation signal receiving unit receives the predetermined operation signal.

1 . A projector comprising:
 a projection system which includes a lens mechanism;   a lens drive unit which drives the lens mechanism;   a lens amount storing unit which stores a lens amount provided by the lens drive unit;   an operation signal receiving unit which receives a predetermined operation signal; and   a lens control unit which controls the lens drive unit in such a manner as to set an initial lens condition of the projection system determined based on the lens amount stored in the lens amount storing unit when the operation signal receiving unit receives the predetermined operation signal.   
     
     
         2 . The projector according to  claim 1 , wherein the initial lens condition is a condition corresponding to a center lens amount between a minimum lens amount and a maximum lens amount stored in the lens amount storing unit. 
     
     
         3 . The projector according to  claim 1 , wherein the initial lens condition is a condition corresponding to a lens amount in which a first lens operation time for operating the lens drive unit in such a manner as to set a minimum lens amount stored in the lens amount storing unit coincides with a second lens operation time for operating the lens drive unit in such a manner as to set a maximum lens amount stored in the lens amount storing unit. 
     
     
         4 . The projector according to  claim 1 , wherein the initial lens condition is a condition corresponding to the lens amount stored in the lens amount storing unit as the lens amount of the projector used last time. 
     
     
         5 . The projector according to  claim 1 , wherein the predetermined operation signal received by the operation signal receiving unit is a power ON operation signal or a power OFF operation signal. 
     
     
         6 . A control method of a projector which includes a projection system which includes a lens mechanism, a lens drive unit which drives the lens mechanism, and a lens amount storing unit which stores a lens amount provided by the lens drive unit, comprising:
 receiving a predetermined operation signal; and   controlling the lens drive unit in such a manner as to set an initial lens condition of the projection lens determined based on the lens amount stored in the lens amount storing unit when the predetermined operation signal is received.
