horizontal scan frequency to produce left and right double-scanned
image signals. A multiplexer alternately selects the left and
right double-scanned image signals at a switching speed of the
doubled horizontal frequency to produce a single multiplexed
double-scanned image signal which is projected onto a single
display screen.
Claim 1 is illustrative of the invention and reads as follows:
1. A steroscopic image display apparatus comprising:
a receiver receiving first and second television signals and
producing left and right image signals therefrom, respectively;
double-scanning means for repeatedly scanning twice each line
of said left and right image signals, provided from said receiver,
at a doubled horizontal frequency of said image signals to produce
left and right double-scanned image signals;
multiplexing means for alternately selecting said left and
right double-scanned image signals at a switching speed of said
doubled horizontal frequency and producing a single multiplexed
double-scanned image signal; and
display means for projecting said multiplexed double-scanned
image signal onto a single display screen.
The Examiner relies on the following prior art:
