Visual prostheses for extreme vision impairment have come closer to reality during these few years. The task of this
research has been to design exoteric devices and study image processing algorithms and methods for different
complexity images. We have developed a real-time system capable of image capture and processing to obtain most
available and important image features for recognition and simulation experiment based on DSP (Digital Signal
Processor). Beyond developing hardware system, we introduce algorithms such as resolution reduction, information
extraction, dilation and erosion, square (circular) pixelization and Gaussian pixelization. And we classify images with
different stages according to different complexity such as simple images, medium complex images, complex images. As
a result, this paper will get the needed signal for transmitting to electrode array and images for simulation experiment.
