This invention concerns a vision enhancement apparatus that improves vision for a vision-impaired user of interface equipment. Interface equipment stimulates the user's cortex, directly or indirectly, to provide artificial vision. It may include a passive sensor to acquire real-time high resolution video data representing the vicinity of the user. A sight processor to receive the acquired high resolution data and automatically: Analyze the high resolution data to extract depth of field information concerning objects of interest. Extract lower resolution data representing the vicinity of the user. And, provide both the depth of field information concerning objects of interest and the lower resolution data representing the vicinity of the user to the interface equipment to stimulate artificial vision for the user.
