Control system, control device, image system, eyeglasses, and image display device

摘要

Technology for controlling image display according to the state of a viewer wearing eyeglasses to view 3D images is provided. When an inclined angle of eyeglasses is in a predetermined range, an image display device alternately displays a left-eye image and a right-eye image. When the inclined angle of the eyeglasses exceeds the predetermined range, the image display device does not switch the left-eye image with the right-eye image. For example, the image display device displays 2D images. Optical shutters of the eyeglasses are synchronized with the left-eye image and the right-eye image. When the image display device does not switch the left-eye image with the right-eye image, the optical shutters are both open.

主权项

1. A control system, for controlling an image system, wherein the image system comprises an image display device for displaying 3D images containing a left-eye image and a right-eye image, and at least one eyeglasses for viewing the 3D images;
the image display device alternately displays the left-eye image and the right-eye image; the at least one eyeglasses comprising:
a first optical shutter and a second optical shutter respectively disposed corresponding to the left-eye image and the right-eye image; anda first control circuit comprising:
a sensor configured to detect an amount of an inclined angle of the at least one eyeglasses with respect to a horizontal direction; anda transmitter configured to transmit a first signal indicating the amount of the inclined angle to the image display device, the transmission being executed regardless of the amount of the inclined angle detected by the sensor;the image display device comprising a second control circuit comprising:
a receiver configured to receive the first signal;a determinator configured to recognize the amount of the inclined angle indicated by the first signal received by the receiver and determine whether the amount of the inclined angle exceeds a first range according to the amount of the inclined angle indicated by the first signal; anda mode switcher configured to switch an action mode of the image display device between a first mode and a second modebased on a determination result of the determinator; wherein the first mode alternately displays the left-eye image and the right-eye image, the second mode does not switch the left-eye image with the right-eye image; and the first control circuit further comprises an optical shutter adjuster, configured when in the first mode to respectively open and close the first and second optical shutters in synchronization with the display of the left-eye image and the right-eye image, and in the second mode, to open both the first and second optical shutters.
