IMAGE GENERATION DEVICE AND METHOD FOR CONTROLLING SAID DEVICE Russian patent published in 2007 - IPC G06T5/00 G03G15/01 

FIELD: generation of colored images.

SUBSTANCE: in accordance to the invention, data of image is stored, which image is supposed to be generated by each image generation block, in predetermined image data storage means; from predetermined means for storing information about exposition change value, showing value of shift relatively to scanning direction on image carrier of each image generator block, information is read about value of exposition change; coordinates of image data storage means reading address are transformed on basis of read information about exposition change value, and image data is read in accordance to information about transformed address; shade is corrected for pixel data, read at coordinate transformation stage based on information about transformed address; predetermined semitone processing is applied to image element data produced at correction stage; image element data, received during semitone processing stage, is outputted as signal for controlling exposition of exposition block of corresponding image generation block.

EFFECT: increased precision of reproduction.
