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. <IMAGE> |
