Image information handling method and device

An arrangement for imaging light on a medium to form a plurality of information elements, comprising:

• a medium for receiving image information;
• means for forming a plurality of light beams;
• means for modulating said plurality of light beams by image information signals;
• means for deflecting said plurality of modulated light beams toward said medium in order that said light beams will scan said medium and form a plurality of rows of light spots on the surface of said medium;
• and
• means for controlling said modulating means in such a manner that a predetermined number of said plurality of light beams receive the same modulation to thereby produce the predetermined number of identical rows of light spots on said medium, said predetermined number being selected in accordance with the desired size of the information elements to be recorded;
• wherein the size of the information elements, defined by adjacent rows of identical light spots, is changed by varying the number of light beams receiving the same modulation.

A device for imaging light on a medium to form a plurality of information elements, comprising:

• a light beam generator;
• a medium for receving image information;
• means for forming a plurality of light beam modulated by information signals;
• deflector means for deflecting said modulated light beams in a first direction;
• means for moving said medium in a second direction different from said first direction;
• optical means for imaging said light beams, after modulation, on said medium;
• and
• means for controlling said forming means in such a manner that a predetermined number of said plurality of light beams receive the same modulation to thereby produce the predetermined number of identical rows of light spots on said medium wherein the size of the information elements is defined by adjacent rows of identical light spots and wherein said predetermined number is selected in accordance with the desired size of the information elements to be recorded.

A device for imaging light on a medium to form a plurality of information elements, comprising:

• a light beam generator;
• a medium for receiving image information;
• first means for deflecting said light beam in a predetermined direction with respect to said medium to form a plurality of light beams;
• means for modulating said plurality of light beams by information signals;
• second means for deflecting said plurality of modulated beams to scan said medium in a direction substantially perpendicular to said predetermined direction;
• means for providing signal corresponding to the desired size of the information elements;
• and
• means for imparting to said modulating means a signal for selectively varying the mode of modulation of said modulating means in such a manner that a predetermined number of said plurality of light beams, selected in accordance with the desired size of the information elements formed on said medium, are modulated by the same information signals in order to form rows of correlated light spots on said medium which define the information elements.
