One aspect of the invention provides a computer-implemented method of conveying a visual image to a blind subject fitted with a visual prosthesis. The computer-implemented method includes: mapping a representation of a visual image onto a two-dimensional array of points having a resolution greater than or equal to an electrode resolution of the visual prosthesis; identifying one or more continuous paths along the mapped representation; and controlling the visual prosthesis to sequentially actuate electrodes along the one or more paths. Another aspect of the invention provides a system including: a visual prosthesis comprising multiple electrodes; and an imaging processing device in communication with the visual prosthesis. The imaging processing device can be programmed to receive an image and perform any of the methods described herein.
