FIELD: physics, image processing.
SUBSTANCE: invention is related to device for image generation for copier, laser printer and fax. Invention provides possibility to prevent any uneven density and deterioration in resolution during reciprocating scanning of laser with application of mirror. Device of image generation generates image on photosensitive element by means of scanning of photosensitive element with laser beam reflected by movable mirror, with the help of reciprocating motion of movable mirror, turn of angle of which is variable in accordance with electric signal. Device detects direction of movable mirror turn, and performs weighing, on the basis of rotation direction, data of two lines image along direction of auxiliary scanning in compliance with ratio of scanning length after beginning of laser recording, so that line of laser scanning would compensate image, which should be generated with the help of movable mirror.
EFFECT: provides possibility to prevent any uneven density and deterioration in resolution during reciprocating scanning of laser with application of movable mirror.
