PROBLEM TO BE SOLVED: To attain a real time caption display device by spatially separating a device for converting a data signal into a picture from a picture display part, mutually connecting the conversion device and the display part through an optical fiber tube for transmitting data as a picture and displaying the picture on the display device. SOLUTION: When a signal cable CB is connected to an optical fiber FB and a head up display(HUD) part of a HUD device is connected to a signal processing circuit part, a sound signal collected by a microphone MH fitted to the bow BO of glasses is inputted to a sound recognizing device in the signal processing part through the cable CB and the sound signal is converted into a character signal (text data) and the character signal is sent to an output terminal. The text data applied from the sound recognizing device to a picture signal conversion part are converted into a picture by a liquid crystal display device and the picture is applied to the surface of a diffusion plate by light from a light source. Light projected from the diffusion plate is reduced to the diameter length of the fiber FB and sent to the fiber FB. |
