Abstract
A video optronic system, comprises a sensor with a supra-hemispheric lens and a matrix detector array, a unit for processing the sensed images, display means for the processed images. The matrix detector, having video rate, comprises: i. L×C pixels, with L and C>2000, each employing correlated double sampling and able to ensure a charge-voltage conversion, and ii. 2 C parallelized analog-digital conversion elements, each comprising a first ADC with output having low level and large gain and a second ADC with output having high level and low gain; the lens exhibits a focal length controlled by the angle of elevation, the focal length being longest in the equatorial plane, and has a numerical aperture lying between 0.9 and 1.6; and the processing unit comprises: i. means for correcting the non-uniformities, ii. means of weighted summation, of several neighboring pixels, iii. means for adapting and compressing the sensed image.
