1. An image adjustment apparatus for processing images output by two image capturing devices arranged with respect to one another so as to capture images representing different respective views of a scene; the image adjustment apparatus comprising: a noise combiner for combining a noise signal with one or both of a pair of corresponding images captured by the two image capturing devices; a difference detector for detecting differences in colour properties between the pair of corresponding images output by the noise combiner; and a colour property adjuster for adjusting colour properties of images from at least one of the image capturing devices on the basis of the differences detected by the difference detector, so as to reduce the differences in colour properties between corresponding images captured by the two image capturing devices.
