Abstract
The present invention relates to camera arrangements with backlighting detection. The camera arrangements are capable of simultaneously capturing real scene data from various viewpoints. This data may include illumination data impinging the scene. The illumination data may then be utilized to alter the apparent illumination of a second image, either real or virtual, which is to be superimposed over the real scene so that the illumination across the entire superimposed scene is consistent. The camera arrangements may utilize combinations of umbilical cables and light tubes to expand or contract the field of capture. The camera arrangements may also include in-line signal processing of the data output.
