Abstract:
1. A vision regeneration assisting apparatus for regenerating vision of a patient going blind by a disease of a retina, comprising: a photosensor to be embedded in the retina of an eye of the patient and for converting an optical signal into an electric signal; photographing means for photographing an object to be recognized by the patient; image processing means for carrying out image processing on an image of the photographed object to detect an edge of the image and obtaining an image representing only a contour of the object; irradiating means for irradiating pulse light having a pulse waveform serving to induce excitation of a nerve cell of the retina which is necessary for perception of vision scanning means provided at the front of the eye of the patient for two-dimensionally scanning the irradiated light over the photosensor; and control means for controlling the irradiating means and the scanning means based on image information obtained by the image processing means; and wherein the scanning means includes a pair of mirrors and a pair of motors for driving the pair of mirrors; and wherein the control means controls driving operation of the pair of motors based on the image information.
