A vision regeneration assisting device for regenerating vision of a patient, comprising: a plurality of electrodes which are stuck and placed into an optic disc of the patient; a setting unit with which first output conditions for an electrical stimulation pulse signal from at least one of the electrodes are set variably; a storage unit which stores a generation position of a phosphene specific to the patient in association with the first output conditions for the stimulation signal that has caused to generate the phosphene, the storage unit storing various first output conditions for the stimulation signals and the generation positions of the phosphenes caused by the stimulation signals based on the various first output conditions in association with each other; a processor which sets second output conditions for the stimulation signal based on image data obtained by an external photography unit and the generation positions of the phosphenes stored in the storage unit, and converts the obtained image data into data for the stimulation signal based on the set second output conditions; and a controller which controls output of the stimulation signal from at least one of the electrodes based on the converted stimulation signal data. In this manner electrical stimulation is applied through the optic disc under applying conditions that are suitable for an individual patient so as to regenerate the patient's vision.
