The invention relates to a video optoelectronic system (100) including a sensor (10) having a super-hemispheric optical unit and a matrix detector, a unit (20) for processing the captured images, and means (30) for displaying the processed images. The matrix detector operates at a video frame rate and includes: i) LxC pixels, where L and C > 2000, each pixel being a correlated double-sampling pixel and capable of providing a charge/voltage conversion; and ii) 2 C analog-to-digital conversion elements (or ADC) arranged in parallel, each element comprising a first ADC having a low output and a high gain, and a second ADC having a high output and a low gain, wherein the optical unit has a focal distance that is controlled on the basis of the site angle, the focal distance being the longest distance in the equatorial plane, and has a digital aperture of between 0.9 and 1.6, and the processing unit includes: i) a means for correcting non-uniformities; ii) a means for the weighted summation of a plurality of adjacent pixels; and iii) a means for adjusting and compressing the captured image. |
