<p>PROBLEM TO BE SOLVED: To assist a user in recognizing the sounds by recognizing a prescribed sound and displaying its corresponding image mark. SOLUTION: A sound type comparison part 123 compares the inputted reference sound type information with the sound type information inputted from a sound analysis part 121. If both sound type information are approximately coincident with each other, the reference sound type information is sent to an image generation part 131. The part 131 extracts the image information corresponding to the coincident reference sound type information from an image information storage part 132 and sends it to a projection screen 142 of an image composition part 141. Then the part 131 extracts the image information corresponding to the no-match signal inputted from the part 123 from the part 132. The extracted image information is sent to the part 141. The part 141 forms an image on the screen 142 based on the image information. Furthermore, the part 141 magnifies the inputted image light via a lens 143 and composes the image light with an image that is inputted from the outside via a half mirror 144 to input them to the user's eyes.</p> |
