Abstract

An image acquisition system that uses multiple cameras or image sensors in a redundant camera array. The cameras or sensors are arrayed in rows and columns so that a viewing area of each camera overlaps a viewing area of an adjacent camera. At least one camera is positioned in the array so that all edges of its viewing area abuts the viewing area of an adjacent camera. The image is displayed or stored in seamless and continuous form in high resolution. The system may also be used in low light conditions for image acquisition. Multiple cameras or sensors may be arrayed on modular panels that mates with and adjacent modular panel. The system is adaptable to image acquisition for X-rays, scanning, photocopying, security systems and the like.
