DISPLAY DEVICE, PROJECTION DEVICE, DISPLAY AUXILIARY DEVICE, AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To allow a user to reliably visually recognize an image for a left eye and an image for a right eye supported by a pair of visual-recognition glasses, while a plurality of display devices are operated displaying the image for a left eye and the image for a right eye by switching the images.SOLUTION: One of two projector devices is set as a master side device 10M that displays a synchronization signal for switching display superimposed on an image to be a display object, and the other is set as a slave side device 10S that does not perform superimposed display. The master side device 10M superimposes the synchronization signal for switching display on the image to be the display object and displays the resulting image with a micro mirror element 14, and the slave side device 10S includes a CPU 28 that controls superimposition of the synchronization signal for switching display on the image.
