PROBLEM TO BE SOLVED: To provide a visual restoration aiding device that can suitably perform visual restoration by using the change in the gaze direction of a patient.SOLUTION: The visual restoration aiding device includes: an extracorporeal device that has a transmitter that transmits a photographic image taken by a photographic appliance that photographs outwards as image data an intracorporeal device that has two or more stimulating electrodes that output an electric stimulation pulse signal that performs electricity stimulation to the retina of a patient based on the image data received by a reception unit and a magnetic flux generator that generates a flux of magnetic induction to a patient eye, and further includes: a visual line direction detector that detects the eye movement of the patient eye located in the flux of magnetic induction a stimulation range setting unit that sets a stimulation range in which the electric stimulation pulse signal generates to the image data based on the detection result of the eye movement of the visual line direction detector and an electric stimulation pulse signal generator that generates an electric stimulation pulse signal corresponding to the stimulation range set by the stimulation range setting unit.COPYRIGHT: (C)2013,JPO&INPIT【課題】 患者の視線方向の変化を利用して好適に視覚再生を行える視覚再生補助装置を提供する。【解決手段】 視覚再生補助装置は、外界を撮影する撮影手段で撮影された撮影画像を画像データとして伝送する送信手段を有する体外装置と、受信手段で受信された画像データに基づき患者の網膜を電気刺激する電気刺激パルス信号を出力させる複数の刺激電極を有する体内装置と、患者眼に対して磁束を発生させるための磁束発生手段を備え,磁束中に位置される患者眼の眼球運動を検出する視線方向検出手段と、視線方向検出手段による眼球運動の検出結果に基づき,画像データに対して前記電気刺激パルス信号を生成する刺激範囲を定める刺激範囲設定手段と、刺激範囲設定手段で設定された刺激範囲に対応する電気刺激パルス信号を生成する電気刺激パルス信号生成手段と、を備える。【選択図】 図2
