Abstract

An imaging apparatus including an IR video camera (1) comprising a sensor array and operable to produce successive video images in the form of pixelated two-dimensional images, the imaging apparatus further comprising a processing arrangement operable to reduce or increase the overall brightness of an image in dependence upon the overall brightness of the pre-enhanced image and the overall brightness of the preceding enhanced image, so that the change in the overall brightness (DC-level) between the enhanced image and the preceding enhanced image is decreased.
