PCT No. PCT/FR93/00443 Sec. 371 Date Dec. 29, 1993 Sec. 102(e) Date Dec. 29, 1993 PCT Filed Nov. 11, 1993 PCT Pub. No. WO93/22840 PCT Pub. Date Nov. 11, 1993.An analogue-digital voltage converter comprising 2n-1 comparators making it possible to generate 2n different voltage levels when the input voltage varies, and a binary coding circuit comprising means (2) for converting the 2n voltage levels into 2n binary codes each having n bits of resolution, characterized in that it comprises additional means (20) making it possible to code the voltage contained in at least one range of variation of the input voltage into an item of information having a number of bits of resolution greater than n. The converter applies more particularly to video signal processing devices (televisions, video recorders, cameras, etc.).
