Abstract
Improved sharpness is obtained in an arrangement for recording continuous-tone pictures in which electro-optic picture scanning apparatus produces picture signals which are applied to an electro-optic recorder to reproduce the picture on a recording medium. Circuits for generating a sharpness signal and for modulating the sharpness signal in dependence upon the picture content of at least a portion of the picture pattern are provided. The modulated sharpness signal is then superimposed on the picture signals to influence the sharpness of pictures recorded by the recorder.
