PROBLEM TO BE SOLVED: To go out of a visually impaired person with a risk of falling, falling, etc., and accidents are constant. As an auxiliary device for recognizing objects for the visually impaired, there was a device that emits ultrasonic waves, detects the reflected waves and notifies them by sound, but detailed information such as a space without objects cannot be obtained and it is widely used. Not done. SOLUTION: In a camera that projects an image of the outside world on an imaging surface in which light receiving elements are arranged vertically and horizontally, sound waves in an audible range proportional to the intensity of the received light are sequentially output along the arrangement of the light receiving elements. It provides a device that helps visually impaired people recognize the outside world by listening to it as a series of sound changes that decompose the projection image of the outside world like a scanning line of a television and reconstructing the projection image of the base in the brain. [Selection diagram] Fig. 1【課題】視覚障害者の外出には転倒、転落などの危険が伴い、事故が絶えない。視覚障害者用の物体を認識する補助装置としては、超音波を発信し、その反射波を検知して音で知らせる装置があったが、物体のない空間など詳細な情報は得られず、普及していない。【解決手段】受光素子を縦横に配列した撮像面上に外界の像を投影するカメラにおいて、受光素子の配列に沿って順次その受けた光の強度に比例した可聴域の音波を出力することにより、テレビの走査線のように外界の投影像を分解した一連の音の変化として聞き、脳内で基の投影像を再構成することで視覚障害者に外界の認識を助ける装置を提供する。【選択図】図１
