SIGNAL PROCESSING APPARATUS
First Claim
1. A signal processing apparatus comprising:
- reversing means for reversing polarity of a video signal; and
mode selecting and executing means for alternately selecting and then executing a first mode and a second mode at a prescribed time interval;
wherein said first mode is for displaying a first video signal on first display means and inputting a second video signal to said reversing means to reverse the polarity of the second video signal and then display the second video signal on second display means; and
said second mode is for inputting the first video signal to said reversing means to reverse the polarity of the first video signal and then display the first video signal on said first display means, and displaying the second video signal on said second display means.

Abstract
A signal processing apparatus is provided with processing units capable of reducing the number of signal processing means and the number of adjustments of a delay time between reversal and non-reversal of video-signal polarity in each of two signal paths in an arrangement in which two liquid-crystal displays (LCDs) are provided in a head-mounted display worn by an observer and each of the two displays is used to display video information viewed by the observer. The signal processing apparatus includes first and second signal sources (1 and 2) each of which generates a video signal, reversing unit 7 for reversing the polarity of one of the two video signals, first selector selectively supplying one of the video signals to the reversing unit, first and second display units (3 and 4) for converting the video signals to respective ones of optical signals, and second selector for selectively supplying a video signal whose polarity is or is not reversed by the reversing unit to the first and second display units.
