Connecting a projection-type display system to an opening and closing device

摘要

A projection-type display system includes: a projection-type display apparatus that alternately switches images for the left eye and images for the right eye and projects the images onto an object; and an opening and closing control device that receives a control signal based on the display states of the images projected onto the object by the projection-type display apparatus and controls switching apertures of stereoscopic image viewing glasses corresponding to left and right eyes, wherein the projection-type display apparatus is connected to one end of a LAN cable and the opening and closing control device is connected to the other end of the LAN cable.

主权项

1. A projection system, comprising:
a projector configured to project images onto a screen, the images including images for a left eye and images for a right eye, the projector comprising control circuitry and a first transmitter that is built into the projector, the first transmitter being configured to receive a control signal from the control circuitry and emit a first wireless signal that controls shutters of stereoscopic image viewing glasses corresponding to left and right eyes based on the control signal; and a second transmitter, located external to the projector, configured to receive the control signal from the control circuitry and emit a second wireless signal that controls the shutters of the stereoscopic image viewing glasses based on the control signal; wherein the control circuitry is configured to determine whether a user has put the projector in a first state or a second state and is further configured to transmit the control signal to the first transmitter in the case that the projector is determined to be in the first state and to transmit the control signal to the second transmitter in the case that projector is determined to be in the second state.
