FIELD: physics.SUBSTANCE: computer has a video card; in the prototype television camera, the first television signal sensor is based on a charge-coupled device (CCD) matrix with "row-frame transfer" and the use of an additional pulse former for clock power supply of the photodetector provides summation in the memory section of charge signals accumulated in its photodetector section. As a result, sensitivity is levelled on the entire field of the composite image.EFFECT: high signal-to-noise ratio at the output of the CCD matrix of the first television signal sensor owing to summation, in its memory section, of charge packets formed in the photodetector section.4 cl, 12 dwg, 3 tbl |
