Abstract

An improved camera system intended for a machine vision system which produces an image output that is specially adapted to be received by a machine vision system. In one embodiment, the camera system receives components from three portions of the electromagnetic spectrum, these being infrared, visible, and ultraviolet, and then combines these three portions essentially as expanded colors in an expanded version of an RGB 'red/green/blue' video system. This provides a better image in all types of weather and visibility conditions. In addition, the camera system includes dynamic range transform logic which selectively compresses the dynamic range of the respective pixel values comprising the image to extract the most useful information from the extended dynamic range of the image. This reduces the amount of information required to be processed while retaining a quality image. The camera system also includes motion compensation logic that removes the motion or jitter caused by the camera system being subject to vibration from various environmental influences. The system also optionally removes stationary background features from the output image.
