Abstract
A data processing device and a method by which image data inputted line by line can be distributed as image data of the plural lines, and processing of the image data and converting the image data to a multiple beam image data can be performed by use of separate memories. The data processing device includes a data inputting mechanism configured to generate line by line in order dot-matrix-state data in synchronism with an input clock; at least m memories having a memorizing capacity capable of memorizing one or more lines of the dot-matrix-state data generated by the data inputting medium, wherein m is an integer equal to or greater than n.times.2, and n is another integer equal to or greater than two; a memory writing-in mechanism configured to write the dot-matrix-state data from the data inputting medium line by line in order into the at least m memories in synchronism with the input clock during a write-in period; a memory reading-out control mechanism configured to write in n lines of data generated by the data inputting mechanism line by line in order into n memories among the at least m memories in synchronism with the input clock, to simultaneously read out (m-n)-lines of d…
