ABSTRACT:
A signal representing an image generated by at least one photosensitive device is processed in real-time to supply, from a scene to be observed having a high dynamic range between the signals corresponding to the darkest areas and to the brightest areas, an image containing no blooming areas. Images of different sensitivities are formed from the same scene to be observed. The brightness level of each point on the most sensitive image is determined. This level is compared with a predetermined threshold. The signal of the most sensitive image is delivered to the display device, for each elementary point on the most sensitive image having a brightness level below the predetermined threshold. An image signal calculated according to the brightness levels of the same elementary point in the images of different sensitivities is delivered to the display device, for any other elementary point on the most sensitive image.According to the present invention, images of different sensitivities are formed from the same scene to be observed, the brightness level of each elementary point on the most sensitive image is determined, this level is compared with a predetermined threshold, the signal of the most sensitive image is delivered to the display device, for each elementary point on the most sensitive image having a brightness level below the predetermined threshold, and an image signal calculated according to the brightness levels of the same elementary point in the images of different sensitivities are delivered to the display device, for any other elementary point on the most sensitive image.
