Abstract
An imaging apparatus including an infrared video camera. The infrared video camera includes a sensor array operable to produce successive video images in the form of pixelated two-dimensional images. The imaging apparatus further comprises 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.
