摘要： In the light amount correction in the main scanning direction, sets of correction values of black and cyan for which the reflection frequency of optical elements are equal to an even number of times are made common to each other (a correction value set—KC), and sets of correction values of magenta and yellow for which the reflection frequency of optical elements are equal to an odd number of times are made common to each other (a correction value set—MY), whereby sets of correction values stored in a correction value storage portion in a correction value setting portion are reduced to two sets. Furthermore, in connection with this, the number of DA converters is reduced to two DA converters of a DA converter—K, C and a DA converter—M, Y.

摘要： A beam light scanning device includes an image data processing unit operable to output image-processed data of neighboring pixels in such a way that the data is divided for distribution into first pixel data and second pixel data. The scanner also includes a synchronizer circuit that receives the first and second pixel data as output from the image data processor and outputs these pixel data while letting them be synchronized with clocks as synchronized based on a horizontal synchronous signal. The scanner further includes a couple of pulse width modulators or “PWMs”, a synthetic circuit, and a laser diode module. The PWMs are for adjustment of the pulse widths of the first and second pixel data as output from the synchronizer circuit respectively. The synthetic circuit combines together the pulse width-adjusted first and second pixel data. The LD emits a light beam indicative of the resultant combined pixel data.
