Abstract
A head-mounted image display apparatus may be worn in a fashion similar to eyeglasses and is provided with left and right shutoff switches operable so that, when the left shutoff switch is operated, a left LCD is active to display a black surface image and a right LCD displays a test pattern, and vice versa. A user may thus easily effect focus and width adjustment without external input and without having to keep one eye closed during adjustment. Also provided are audio earphones and a detection circuit for detecting input of a three dimensional image signal. Also, a surround audio processing circuit is provided which is active according input of the three dimensional image signal.
