FIELD: physics. ^ SUBSTANCE: television camera includes a second frame delay unit. The CCD matrix includes a partition electrode, a memory section, a second horizontal register and a second charge-to-voltage converter. The signal processor includes a second video pulse. ^ EFFECT: wide dynamic range of gray gradations of the image formed by the television camera through optimisation in the photodetector of the charge-to-voltage converter. ^ 3 cl, 7 dwg, 2 tbl |
